Abstract
BACKGROUND Oral focal epithelial hyperplasia (FEH) is an uncommon infection affecting humans, chimpanzees, bonobos, and howler monkeys. This study describes 10 cases of free-ranging brown howler monkeys (Alouatta guariba clamitans) diagnosed with FEH and Alouatta guariba Papillomavirus 1 (AgPV 1). METHODS We analyzed demographic characteristics, rescue conditions, clinical and pathological findings, and species-specific behavior factors in these cases. The study assessed the frequency of occurrence and potential contributing factors of FEH and AgPV 1 infection. RESULTS The frequency of FEH was 8.13%. Most affected howlers were adult or geriatric males with comorbidities or stressful conditions. Clinical and pathological observations were consistent with AgPV 1 infection. Species-specific behaviors and environmental stressors were identified as contributing factors. CONCLUSIONS FEH associated with AgPV 1 affected mainly adult or geriatric males with ongoing comorbidities or stressful conditions. Further research is needed to understand these factors for effective management.

Abstract
Cutaneous plaques and squamous cell carcinoma (SCC) are common in captive North American snow leopards (SLs) (Panthera uncia). Our objective was to determine whether these lesions are potentially associated with papillomavirus(es). Polymerase chain reaction (PCR) was performed on 3 cutaneous plaques using degenerate primers for papillomaviruses. A putatively novel papillomavirus was identified that shared 76% sequence identity to Felis catus papillomavirus 2. Specific PCR for this virus was performed on 5 cutaneous SCC samples and 7 normal skin samples, which were all positive. In situ hybridization for this putatively novel virus was performed, which revealed strong hybridization signals within hyperplastic cells in cutaneous plaques (n = 3) and within neoplastic cells in cutaneous SCC samples (n = 5). No hybridization signals were identified within normal skin. Ultimately, identification of a causal viral agent in the development of plaques and SCC in SLs will help guide therapeutic intervention and lay the foundation for development of prophylactic vaccines.

Feline Facial Spindle Cell Tumors in 29 Cats: Histomorphological and Immunohistochemical Characterization. Animals (Basel) 2024; 14:1103.

Abstract
Soft tissue tumors/sarcomas (STSs) in felines, encompassing a variety of mesenchymal tumors with similar histomorphological features, present diagnostic challenges due to their diverse cellular origins and the overlap with other tumor types such as feline sarcoid. This study aimed to delineate the clinical, histomorphological, and immunohistochemical characteristics of 34 feline facial spindle cell tumors affecting 29 cats, including testing for bovine papillomavirus type 14 (BPV14), the virus causing feline sarcoids. Only five out of 12 tumors previously diagnosed as feline sarcoids based on histomorphology were confirmed by PCR for BPV14, underscoring the importance of comprehensive diagnostic approaches to accurately distinguish between STSs and feline sarcoids. This study shows that most facial spindle cell tumors were compatible with peripheral nerve sheath tumors (PNSTs) based on positive immunohistochemical staining for Sox10 and other immunohistochemical markers such as GFAP, NSE, and S100. Some of these tumors displayed as multiple independent masses on the face or as erosive and ulcerative lesions without obvious mass formation, an atypical presentation and an important highlight for general practitioners, dermatologists, and oncologists. This study also describes periadnexal whorling of neoplastic cells as a novel histomorphologic finding in feline facial PNSTs and emphasizes Sox10 as a useful complementary immunohistochemical marker for the diagnosis of facial PNST in cats, providing valuable insights for veterinary pathologists.

Abstract
As part of a comparative research agenda that promises insights that help extend the human lifespan and combat cancer, cancer prevalence in zoo animals has received recent attention. Here, we want to draw attention to a principle of cancer research that was introduced into the zoo world as early on as 1933, but that seems to have gone somewhat forgotten: Cancer is mainly a disease of old age, and therefore studies aiming at identifying taxa that are particularly susceptible or resistant to cancer must control for whether the respective zoo populations are 'old.' In a comparative context, 'old age' cannot be measured in absolute terms (e.g., years), but only in relation to a species' maximum lifespan: Species that achieve, across zoos, a higher mean lifespan as a percent of their maximum lifespan are 'older.' When applying this metric to former as well as more recently published data on cancer prevalence, it appears that those species that become relatively old in zoos-in particular, the carnivores-have a relatively high cancer prevalence. Any improvement in animal husbandry-which reduces premature deaths-should, by default, lead to more cancer. Cancer in zoo animals, like any other old-age condition, might therefore be embraced as a proxy for good husbandry. Rather than following a sensationalist approach that dramatizes disease and death per se, zoos should be clear about what their husbandry goals are, what relative longevities they want to achieve for which species, and what old-age diseases they should therefore expect: in the end, one has to die of something.

Abstract
Our study aims are: (1) to evaluate phenotypically normal canine conjunctival and orbital tissue and tissue from canine lobular orbital adenomas (CLOAs) for the presence of viral genomic material and (2) phylogenetically classify detected DNA viruses to determine if a DNA virus is associated with CLOAs. A total of 31 formalin fixed paraffin embedded CLOA tissue samples, 4 papillomas or sarcoid, and 10 fresh clinically normal conjunctival tissues were included in this study. Genomic DNA was isolated from all samples and sequencing libraries were prepared. The libraries were molecularly indexed and pooled and viral DNA was enriched via targeted sequence capture utilizing ViroCap. The libraries were sequenced on the Illumina HiSeq platform and compared to known viral DNA reference genomes to identify viral DNA. Carnivore parvovirus was identified in 6.4% and 20% of CLOA tissue and normal conjunctival samples, respectively. This study showed that conjunctival tissue from healthy dogs and CLOAs uncommonly harbor DNA viruses, and no DNA virus was associated with these tumors. Further studies are needed to evaluate the etiologic cause of CLOAs.

Abstract
Papillomaviruses (PVs) are a family of small DNA tumor viruses that can induce benign lesions or cancer in vertebrates. The observation that animal PV capsid-proteins spontaneously self-assemble to empty, highly immunogenic virus-like particles (VLPs) has led to the establishment of vaccines that efficiently protect humans from specific PV infections and associated diseases. We provide an overview of PV-induced tumors in horses and other equids, discuss possible routes of PV transmission in equid species, and present recent developments aiming at introducing the PV VLP-based vaccine technology into equine medicine.

Abstract
The involvement of Felis catus papillomavirus type 2 (FcaPV2) in feline Merkel cell carcinoma (MCC) has been previously hypothesized. In this study, the expression and localization of FcaPV2 oncogene mRNA, the integration of FcaPV2 genes, and p53 mutations in feline MCC were examined by RNAscope in situ hybridization (ISH), whole genome sequencing (WGS), and Sanger DNA sequencing, respectively. Furthermore, the morphological and molecular characteristics of FcaPV2-positive (FMX-MCC01) and FcaPV2-negative (AS-MCC01) MCC cell lines were compared in vitro and in vivo using immunofluorescence, ISH, xenotransplantation into mice, and immunohistochemistry. ISH for FcaPV2 E6/E7 detected viral RNA in 18/21 FcaPV2-positive MCC and not in 1/1 FcaPV2-negative MCC. WGS of 2 FcaPV2-positive cases revealed the integration of FcaPV2 genes in both cases. In cultured cells and xenograft tissues of FMX-MCC01, most cells were positive for E6/E7 by ISH and p16CDKN2A, a few cells were positive for the retinoblastoma protein (pRb), and all cells were negative for p53. In cultured cells and xenograft tissues of AS-MCC01, all cells were negative for p16CDKN2A, most cells were positive for pRb, and some cells were positive for p53. Missense mutations in p53 were identified in 8/10 FcaPV2-positive and 1/1 FcaPV2-negative MCC. These results suggest that the expression of integrated FcaPV2 oncogenes might be associated with reduced expression of the tumor suppressor proteins pRb and p53 and might contribute to the development of feline MCC. On the other hand, p53 mutations may be involved in both FcaPV2-positive and FcaPV2-negative MCC tumorigenesis.

Abstract
Papillomaviruses (PVs) are well recognized to cause pre-neoplastic and neoplastic diseases in humans. Similarly, there is increasing evidence that PVs play a significant role in the development of pre-neoplastic and neoplastic diseases of the haired skin of dogs and cats, and the mucosa of horses. As the mechanisms by which PVs cause neoplasia are well studied in humans, it is valuable to compare the PV-induced neoplasms of humans with similar PV-associated neoplasms in the companion animal species. In the second part of this comparative review, the pre-neoplastic and neoplastic diseases thought to be caused by PVs in humans, dogs, cats, and horses are described. This includes PV-induced cutaneous plaques, cutaneous squamous cell carcinomas (SCCs) and mucosal SCCs within the four species. The review concludes with a discussion about the potential use of vaccines to prevent PV-induced diseases of dogs, cats, and horses.

Abstract
Canis familiaris papillomavirus (CPV) is a member of the Papillomaviridae family and is found in dogs. After infection, the host can remain asymtomatic or develop benign ephitelial neoplasms such as papillomas and pigmented viral plaques, which can progress to cancer, in the form of squamous cell carcinoma (SCC). In humans, 227 types of human papillomavirus (HPV) have been described, with a well-established risk classification for cancer development. In addition, it is also known that variants of some high-risk HPV types may present different risks in respect of SCC development. In dogs, however, only a few types of CPV have been identified, despite the growing interest in this area, and knowledge on the genetic characterization of CPV variants is still scarce. Recent studies of CPV have shown that, as with HPV, benign neoplasia can develop into cancer, but it is believed that there are many more types and variants still to be described. Therefore, the aim of this study was to describe the genetics and biology of CPV, with the focus on what is known about lesions, geographic localization, virus types and variants.

Abstract
In recent years, growing attention has been paid to the influence/role of infectious diseases in tumour development and progression. Investigations have demonstrated that some infectious organisms can have a direct role in the development of neoplasia, whereas others can predispose to neoplasia by alterations in the immune response, or by creating a pro-inflammatory environment. Feline leukaemia virus was one of the first infectious agents recognised as an oncogenic organism, and along with feline immunodeficiency virus has received the most attention. Since the discovery of this retrovirus, several other organisms have been associated with neoplastic processes in cats, these include gammaherpes virus, mouse mammary tumour virus, papillomaviruses, hepadnavirus, Helicobacter species, and the parasitic infections Platynosomum fastosum and Opisthorchis viverrini. This review summarises the findings to date.

Histopathological Findings and Metagenomic Analysis of Esophageal Papillary Proliferation Identified in Laying Broiler Breeders. Vet Sci 2022; 9:vetsci9070332.

Abstract
Simple Summary This study describes the histopathological finding of mucosal papillary proliferation observed in the esophagus of chicken and attempts to determine its infectious etiology using metagenomics. Unlike squamous metaplasia of the esophageal mucosa due to vitamin A deficiency, the stratified squamous epithelial cells of the esophagus were completely replaced by increased numbers of ducts/ductules, lymphocytes, and connective tissue, and multiple hyperplasia of the esophageal gland was observed. As the result of the metagenomic analysis of esophagus samples from this chicken, no viral cause was identified; however, the contributing role of Bradyrhizobium sp. could not be excluded. In this study, we report the first histopathological examination of a rare case of an esophageal papillary lesion appearing as adenoma in a chicken and highlight the importance of histopathological results for a definitive diagnosis of such cases. Abstract White or pale-yellow nodules 2–7 mm in length were observed in the esophageal lumen in a number of laying broiler breeders with reduced laying rates. Metaplasia of the mucosal epithelial layer and mucous gland, as well as lymphocyte infiltration under the esophageal mucous gland and epithelial cell layer, were observed, which we found were caused by vitamin A deficiency. In one chicken, however, the stratified squamous epithelial cells of the esophagus were completely replaced by increased numbers of ducts/ductules, lymphocytes, and connective tissue, resulting in a papillary morphology. The ducts were surrounded by a fibrous stroma. Multiple hyperplasia of the esophageal gland was also observed and the esophageal glands were lined by a single layer of columnar cells, and a large number of lymphocytes were infiltrated into the submucosal layer. Based on the gross findings, this papillary proliferation was considered papilloma, but histopathologically, a mass composed of squamous epithelium was not observed. Therefore, the papillary lesion appeared as adenoma with squamous metaplasia of the esophageal gland and ectasia, or mucosal epithelial papillary hyperplasia, associated with chronic esophagitis. A metagenomic analysis of the esophagus samples from this chicken was performed to determine the infectious etiology. No viral cause was identified; however, a contributing role of Bradyrhizobium sp. could not be excluded. In this study, we report the first histopathological examination of a rare case of esophageal papillary proliferation in a chicken and highlight the importance of histopathological results for a definitive diagnosis of such cases.

Abstract
Papillomaviruses, which are epitheliotropic and may induce epithelial tumors, have been identified in several avian species, including ducks. An adult female mallard duck (Anas platyrhynchos) was admitted to a wildlife rehabilitation center with 2 beige, well-demarcated, firm masses: one in the subcutis under a wing, and the other on a digit of the right foot. After euthanasia, the masses were fixed in formalin for histologic examination. Both tumors had a lobular organization with cartilage cores surrounded by densely cellular interlacing bundles of spindle cells. Neoplastic chondroblasts in both masses, particularly the digital mass, contained basophilic intranuclear inclusion bodies, which consisted of assembly complexes of icosahedral virions of 44-nm diameter. Next-generation sequencing allowed whole genome assembly of a novel papillomavirus (Anas platyrhynchos papillomavirus 2) related most closely to Fulmarus glacialis papillomavirus 1 (59.49% nucleotide identity). Our case supports the observation that certain papillomaviruses can productively infect mesenchymal cells and induce neoplasia.

Papillomaviruses in Domestic Cats. Viruses 2021; 13:v13081664. [PMID: 34452528 PMCID: PMC8402708 DOI: 10.3390/v13081664] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2021] [Revised: 08/20/2021] [Accepted: 08/20/2021] [Indexed: 12/26/2022] Open
Abstract
Papillomaviruses (PVs) are well established to cause hyperplastic papillomas (warts) in humans and animals. In addition, due to their ability to alter cell regulation, PVs are also recognized to cause approximately 5% of human cancers and these viruses have been associated with neoplasia in a number of animal species. In contrast to other domestic species, cats have traditionally been thought to less frequently develop disease due to PV infection. However, in the last 15 years, the number of viruses and the different lesions associated with PVs in cats have greatly expanded. In this review, the PV life cycle and the subsequent immune response is briefly discussed along with methods used to investigate a PV etiology of a lesion. The seven PV types that are currently known to infect cats are reviewed. The lesions that have been associated with PV infections in cats are then discussed and the review finishes with a brief discussion on the use of vaccines to prevent PV-induced disease in domestic cats.

Abstract
We encountered a case of cutaneous squamous cell carcinoma (SCC) in a 17-year-old female
koala at a zoo. A fragile, papillary, elevated mass was found on the third digit of the
right hind limb. SCC was identified histopathologically: squamous cell-like polygonal
tumor cells showed a nest-like growth pattern with epidermal down growth, central
keratinization and necrotic foci, and invaded dermal connective tissues. Metastatic
lesions were observed in various organs, including the lung and axillary lymph node: in
the lung, multiple metastatic foci similar to the primary lesion, and in the axillary
lymph node, individual polygonal tumor cells infiltrated the sinusoids.
Immunohistochemistry revealed that the tumor cells were positive for proliferating cell
nuclear antigen, which exhibited 32–33% of labeling indices in the tumor cells. To our
knowledge, this is the first report of a case of SCC in a digit of a koala.

Abstract
Abstract
Sarcoid tumors were described by means of histopathological and molecular procedures in a 5-year-old donkey. Histopathological examination showed epithelial changes including hyperkeratosis, epithelial hyperplasia, koilocytosis, and rete peg formation. Neoplastic fibroblastic cells were plumb, large spindle to stellate and embedded in dense collagenous tissue. Results of Polymerase Chain Reaction and DNA sequence analysis showed that the etiological agent belonged to Bovine Papilloma Virus-II species in the delta papilloma virus genus. This case study represents the first report demonstrating the presence of Bovine Papilloma Virus-II in donkey sarcoid.

Proteomic profiles and cytokeratin 13 as a potential biomarker of Ovis aries papillomavirus 3-positive and negative cutaneous squamous cell carcinomas. Res Vet Sci 2020; 134:112-119.

Abstract
Ovis aries papillomavirus 3 (OaPV3) is an epidermotropic PV reported in sheep cutaneous squamous cell carcinoma (SCC). The presence of OaPV3 DNA and its transcriptional activity in cutaneous SCC, as well as its in vitro transforming properties, suggest a viral etiology for this neoplasm. Nevertheless, the reactome associated with viral-host interaction is still unexplored. Here, we investigated and compared the proteomic profiles of OaPV3-positive SCCs, OaPV3-negative SCCs, and non-SCC samples by liquid chromatography tandem-mass spectrometry (LC-MS/MS) analysis, bioinformatics tools, and immunohistochemistry (IHC). OaPV3-positive SCCs (n = 3), OaPV3-negative SCCs (n = 3), and non-SCCs samples (n = 3) were subjected to a shotgun proteomic analysis workflow to assess protein abundance differences among the three sample classes. Proteins involved in epithelial cell differentiation, extracellular matrix organization, and apoptotic signaling showed different abundances in OaPV3-positive SCCs tissues (P ≤ 0.05) when compared to the other tissues. Cytokeratin 13 (CK 13) was among the most increased proteins in OaPV3-positive SCC and was validated by immunohistochemistry on 10 samples per class, confirming its potential as a biomarker of OaPV3 infection in SCC. Collectively, results provide a preliminary insight into the reactome associated with viral-host interaction and pave the way to the development of specific biomarkers for viral-induced sheep SCC.

Abstract
Equus caballus papillomavirus type-2 (EcPV-2) has been proposed as a causal factor in equine genital squamous cell carcinoma (SCC). This study had 2 objectives: first, calculate the frequency of papillomavirus (PV) and EcPV-2 infection in papillomas, carcinomas in situ (CIS), and SCCs in Western Canadian horses; and second, determine if EcPV-2 status of equine SCCs is associated with overall survival (OS). EcPV-2 status of 115 archived tissue samples, spanning 6 years, was determined using broad spectrum (MY09/11) and EcPV-2-specific polymerase chain reaction (PCR) assays, EcPV-2-E6/E7 chromogenic RNA in situ hybridization (R-ISH), and amplicon sequencing. A retrospective survey gathered data on history, outcome, breeding, treatment, and rationales of referring veterinarians when managing PV-associated diseases. Histologic grade and completeness of surgical margins of SCCs were also considered. EcPV-2 DNA was identified in 10/58 (17%) SCC, 8/27 (30%) papillomas, 0/5 CIS, and 0/11 lesions identified as "other." Overall, 18/101 (18%) of these lesions were positive for EcPV-2. EcPV-2 was identified in 10/35 (29%) SCCs arising from genital tissues but in 0/22 SCCs from other locations. There was no association between breeding history and EcPV-2 status of genital SCCs. EcPV-2 status of genital SCCs was not associated with OS (P = .76). The strongest negative predictors of OS were a lack of treatment (P < .01) and recurrence post-treatment (P < .01). Weaker predictors of OS included older age at time of diagnosis (P = .02). Completeness of margins at surgical excision, concurrent disease, treatment type, anatomic location of the SCC (anogenital vs other), and histologic grade of the SCC did not influence OS (P > .1).

Abstract
Equus caballus papillomavirus type 2 (EcPV-2) has been recognized as a potential cause of a subset of genital squamous cell carcinomas (SCCs) in horses. In the current study, we measured EcPV-2 seropositivity in 50 healthy horses from Western Canada, and these were compared to a herd of horses with known EcPV-2 exposure. Second, the presence of EcPV-2 DNA was measured using EcPV-2-specific PCR (polymerase chain reaction), performed on a variety of tissues collected at necropsy from 70 horses that lacked any history, gross, or histologic evidence of neoplasia or papillomavirus-associated disease. EcPV-2-specific RNA in situ hybridization (R-ISH) was performed on PCR-positive samples to identify the specific tissues infected. The prevalence of asymptomatic infection with EcPV-2 in Western Canadian horses was 20/70 (29%). Exposure to EcPV-2 as measured by seropositivity was 18/50 (36%). EcPV-2 positivity by anatomic location, as measured by R-ISH, was as follows: penis 10/29 (35%), vulva 5/34 (15%), eyelid 8/68 (12%), oral mucosa 7/65 (11%), skin from muzzle 7/68 (10%), and retropharyngeal lymph node 2/64 (3%). The youngest horses with EcPV-2 infection, based on PCR, were fetuses, suggesting for the first time that vertical transmission of EcPV-2 occurs in horses. The current study observed an increased prevalence of EcPV-2 as compared to previous studies. We suggest that this difference is due to our use of biopsies in place of superficial swabs. We propose that EcPV-2 infection in asymptomatic horses is more common than previously reported and that the virus' role in equine genital SCCs may be more complex than originally thought.

Abstract
Papillomaviruses (PVs) are circular double-stranded DNA virus belonging to Papillomaviridae family. During the infection cycle, PVs translate proteins that can influence cell growth and differentiation, leading to epidermal hyperplasia and papillomas (warts) or malignant neoplasms. Canis familiaris papillomaviruses (CPVs) have been associated with different lesions, such as oral and cutaneous papillomatosis, pigmented plaques, and squamous cell carcinomas (SCCs). Here, we report a clinical case of a mixed bred female dog with pigmented plaques induced by CPV16 (Chipapillomavirus 2) that progressed to in situ and invasive SCCs. Gross and histological findings were characterized, and the lesions were mainly observed in ventral abdominal region and medial face of the limbs. In situ hybridization (ISH) revealed strong nuclear hybridization signals in the neoplastic epithelial cells, as well as in the keratinocytes and koilocytes of the pigmented viral plaques. The full genome of the CPV16 recovered directly from the lesions was characterized, and the phylogenetic relationships were determined. The identification of oncoprotein genes (E5, E6, and E7) by high throughput sequencing (HTS) and their expected domains are suggestive of the malignant transformation by CPV16.

Abstract
Coilocytic atypism of tumors of epithelial origin is considered as a marker of HPV infection, regardless of the type of neoplasm, which is a clinical manifestation of papillomatosis. Many neoplasms in dogs are diagnosed depending on the identification of specific cellular and tissue atypism, which underlies the histological diagnosis. According to the recent studies, the following types of neoplasm can be distinguished depending on the taxonomic affiliation of HPV: papillomas of various localization, cancerous epidermodysplasia verruciformis, pigment affects (including plaque), inverted and squamous papillomas, squamous cell carcinomas. Histological studies are an affordable diagnostic method that allows studying the morphological features of coylocytary atypism of squamous papillomas of dogs. Squamous cell papillomas in dogs have a number of morphological and cytological features, due to the predominance of the keratinization process. In this case, the process of differentiation of epithelial cells is consistent and all layers typical of the skin of dogs are distinguished. The corneal layer prevails over all the described layers, the activity of the cells of the basal layer is noted. Coilocytes are localized in a spinous and granular layer, but depending on their location, they have distinctive morphological and quantitative characteristics. Despite the polymorphism of the manifestation of coylocytary atypism in animals within the limits of specific affects, as well as depending on the type of neoplasm, there are no common morphological criteria for evaluating coylocytosis depending on oncogenesis. It was noted that the morphological and quantitative characteristics of coilocytes depend on their location, while they have a morphology described by many researchers, including in various animal species.

Abstract
Papillomaviruses cause persistent infections in skin and mucosal membranes and, in at least one species, are also be able to infect a tissue of mesenchymal origin. Infections may either be subclinical or induce proliferative lesions. Of the known papillomaviruses, the majority that have been characterized are from humans and other mammals. Currently, only fifteen complete bird and reptile papillomavirus genomes have been described, and they have been found in birds (n = 11), turtles (n = 2), and snakes (n = 2). Using next-generation sequencing technologies and virus-specific PCR, we have identified two novel papillomavirus genomes, Hemidactylus frenatus Papillomavirus 1 and 2 (HfrePV1, HfrePV2), in the widely distributed and highly invasive Asian house gecko (H.frenatus) and mute gecko (Gehyra mutilata) on Christmas Island and Cocos (Keeling) Islands. HfrePV1 was also detected in critically endangered Lister’s geckos (Lepidodactylus listeri) in their captive breeding colony on Christmas Island. Tissue-containing virus included epidermis, oral mucosa, and liver (HfrePV1) and epidermis, liver, and colon (HfrePV2). Concurrent infections were found in both H.frenatus and G.mutilata. Invasive mourning geckos (Lepidodactylus lugubris) (n = 4), Sri Lankan house geckos (Hemidactylus parvimaculatus) (n = 3), flat-tailed house geckos (Hemidactylus platyurus) (n = 4) from the Cocos Islands, and blue-tailed skinks (Cryptoblepharus egeriae) (n = 10) from Christmas Island were also screened but were not found to be infected. The novel HfrePV1 and HfrePV2 genomes were 7,378 bp and 7,380 bp in length, respectively, and each contained the early (E1, E2, and E7), and late (L1 and L2) open-reading frames. Phylogenetic analysis of the concatenated E1, E2, and L1 proteins from both papillomaviruses revealed that they clustered with, but were basal to, the Sauropsida clade containing bird and reptile viruses. This study sheds light on the evolution of papillomaviruses and the distribution of pathogens in a highly invasive species impacting endangered populations of geckos.

Abstract
BACKGROUND Canine lobular orbital adenomas are benign tumors that arise from orbital glandular tissue and extend into the orbit, conjunctiva, and third eyelid. Surgical excision is challenging and recurrence rates are high following excision alone. Enucleation and exenteration reduces the likelihood of recurrence, but is a radical therapeutic option for an otherwise visual and comfortable eye. Human papillomavirus causes 4.5% of worldwide cancers in people and has been identified in up to 23% of benign salivary gland tumors. To date, the etiology of canine lobular orbital adenomas has not been established and it is reasonable to consider canine papillomaviruses as an associative agent with benign glandular tumors in dogs. Identification of the underlying etiology of these tumors may help establish treatment or preventative measures. The purpose of this study was to evaluate conjunctival and orbital tissue of phenotypically normal dogs and tissue from canine lobular orbital adenomas for the presence of papillomavirus DNA. RESULTS Thirty seven canine lobular orbital adenoma samples (36 formalin fixed paraffin embedded (FFPE) tissue samples from 33 dogs and one freshly collected sample) were evaluated via polymerase chain reaction for the presence of papillomavirus DNA. Conjunctival tissue samples, from 10 dogs with normal ocular examinations, excised immediately following euthanasia, were used as phenotypically normal controls. Three FFPE and one freshly collected tissue samples previously confirmed to be positive for papillomavirus DNA were used as positive controls. PCR products verified positive controls. Papillomavirus DNA was not detected in fresh conjunctival tissue of the phenotypically normal control dogs or in samples of fresh or FFPE canine lobular orbital adenoma tissue. CONCLUSIONS An association between papillomavirus and the development of canine lobular orbital adenomas is unlikely. Further research is needed to evaluate if other viruses play a role in the pathogenesis of canine lobular orbital adenomas.

Abstract
OBJECTIVES Papillomaviruses (PVs) are ubiquitous host- and site-specific viruses. PV infections in cats are associated with oral papillomas, viral plaques, Bowenoid in situ carcinomas (BISCs), squamous cell carcinomas and sarcoids; this association is primarily based on PCR detection of PV DNA within said lesions. PV DNA is frequently detectable on normal feline skin; thus, it is possible that some of the implicated DNA is commensal rather than associated with lesion formation. Therefore, the aim of the present study was to use fluorescence in situ hybridization (FISH) to localize PV DNA within feline BISCs, to provide additional evidence that PV infection may influence the development of these neoplasms. METHODS FISH probes targeting Felis catus papillomavirus type 2 (FcaPV2) DNA were used to localize FcaPV2 DNA within 42 BISCs from which FcaPV2 DNA had previously been amplified via PCR. RESULTS Fifteen of 42 BISC lesions (35.7%) demonstrated intralesional FcaPV2 using FISH. Probe annealing was predominantly located within the nuclei of koilocytes found in the upper strata of the epidermis. Probes were typically scattered multifocally within the lesions; most commonly this was near the periphery of the BISCs. CONCLUSIONS AND RELEVANCE These results confirm that a proportion of BISCs contain FcaPV2 DNA. These results further support a causative association between FcaPV2 and BISCs in cats.

Abstract
Over the span of several years, 3 Indo-Pacific humpbacked dolphins died and were necropsied in Thailand. These 3 animals were all captive-bred at Oasis Sea World (Chanthaburi, Thailand), and displayed similar macroscopic progressive cutaneous lesions diagnosed as squamous cell carcinomas. In 2 of the 3 animals, necropsy revealed a severe fibrinosuppurative tracheitis and pneumonia secondary to metastasis of a cutaneous squamous cell carcinoma which extended from the head throughout the trunk and flippers. The tumors were characterized by coalescing botryoid masses with severe areas of cutaneous erosion, ulceration and necrohemorrhagic dermatitis. There was evidence of metastasis to the lungs and hilar lymph nodes. Necropsy of the third animal revealed similar progressive cutaneous squamous cell carcinomas but without evidence of metastasis. DNA molecular analysis of homogenized neoplastic tissue was conducted using polymerase chain reaction for both herpesvirus and papillomavirus in 2 of the 3 cases. In the first case, the tissues were positive for a herpesvirus alone, and this was phylogenetically classified as an alphaherpesvirus. This new herpesvirus has been tentatively named Sousa chinensis alphaherpesvirus. The second animal was negative for this novel herpesvirus and the third was not analyzed. In addition to the captive population, there is photographic evidence from 2 separate wild populations of Indo-Pacific humpbacked dolphins in the Gulf of Thailand, of a macroscopically identical proliferative and ulcerative process suspected to be squamous cell carcinomas.

Abstract
PRACTICAL RELEVANCE Prior to 1990 papillomaviruses (PVs) were not recognised to infect or cause disease in domestic cats. Since this time, the use of histology, immunohistochemistry and, more recently, molecular techniques has revealed that PVs almost certainly cause feline viral plaques and Bowenoid in situ carcinomas, oral papillomas and feline sarcoids. In addition, there is increasing evidence that PVs play a significant role in the development of feline cutaneous squamous cell carcinomas, one of the most common skin cancers of cats. Recent studies have also revealed that most cats are asymptomatically infected with PVs. This raises a critical question that is currently unanswered: why do only a small proportion of infected cats develop disease? In the future it may be possible to prevent PV-induced diseases by using a vaccine to prevent PV infection. Alternatively, novel therapies may be developed that prevent PVs from causing clinical disease by stimulating the host immune response. CLINICAL CHALLENGES A recognition of the skin diseases caused by PVs is important to more accurately predict disease progression. Unfortunately, there are currently no non-surgical treatments that have been proven to be beneficial in cats and clinical management of PV-induced skin disease in cats can be challenging. GLOBAL IMPORTANCE PVs have a worldwide distribution and negatively impact feline health and welfare globally. AUDIENCE This review is aimed at clinicians, especially those who regularly treat cats with skin disease. The review will also be useful to oncologists and researchers who have an interest in how cancer develops in cats. EVIDENCE BASE In producing this update the authors have drawn on recently published peer-reviewed literature.

Abstract
The present paper describes Felis catus papillomavirus (FcaPV) type 5-associated cutaneous mass in a Domestic Shorthair cat. Histological examination revealed multicentric
epidermal acanthosis with papillomavirus-associated cytopathic changes, which progressed to a tumor lobule with intact basement membrane. An association between FcaPV-5 and the cutaneous
lesions was confirmed by detection of virus antigen and genes using immunohistochemistry, polymerase chain reaction (PCR), sequencing analysis, and in situ hybridization.
Based on these findings, the lesions were diagnosed as FcaPV-5-associated viral plaques and Bowenoid in situ carcinoma (BISC). To date, this is the first reported case of
FcaPV-5 infection in a cat in Japan, and the second case reported worldwide. For the first time this papillomavirus type is associated with BISC development.

Abstract
A 12-year-old neutered male domestic shorthair cat was presented with a 3-year history of multiple nonpruritic, ulcerated, plaque-like skin lesions but no other clinical signs. A systemic examination revealed mild lymphadenopathy. Histopathologic analysis of the skin lesions revealed multicentric basosquamous carcinoma (BSC). Immunohistochemical analysis, PCR, and sequencing detected Felis catus papillomavirus type 2 (FcaPV-2) within the tumors. As BSC is rare in cats, clinical behavior has not been established. To our knowledge, this is the first case report to demonstrate detection of FcaPV-2 within a BSC in a domestic cat.

Abstract
Cutaneous pigmented viral plaques is a disorder of epidermal growth caused by canine papillomavirus type 4 (CPV-4). There is currently no standard of care for managing this condition and it has not been reported in the Hungarian Vizsla. This case series documents the clinical features of canine pigmented viral plaques in Hungarian Vizsla dogs and the treatment of a severe case using a novel topical agent tigilanol tiglate (EBC-46). A 4-year-old spayed Hungarian Vizsla in Australia was presented for multiple cutaneous pigmented plaques extending from the ventral cervical region. Lesions were neither painful nor pruritic. The number and size of these sessile plaques increased over time, with the largest lesions eventually taking on an exophytic (wart-like) appearance. These lesions did not affect the dog's wellbeing. Two much less severe cases in a 5-year-old Vizsla from the UK and a 7-year-old Vizsla from New Zealand were also diagnosed. Histology was consistent with papillomavirus-induced pigmented plaques and CPV-4 DNA sequences were amplified from paraffin-embedded formalin-fixed tissue using the polymerase chain reaction from the most severely affected patient. Topical imiquimod was ineffective although used for only a short time. Two topical applications of novel anti-neoplastic diterpene ester tigilanol tiglate as a gel, 9 days apart, greatly reduced the size and number of lesions in a limited portion of skin treated, over the lateral hock. While CPV-4 has been previously reported to cause pigmented plaques, most commonly on pug dogs, but sporadically on other breeds, this is the first report of this virus causing plaques in Hungarian Vizslas. The cases illustrate some of the difficulties in diagnosing papillomavirus-induced disease in dogs, especially in its early stages. Topical tigilanol tiglate is a potentially useful topical therapy for this viral-induced disorder of cell growth and represents a treatment deserving of further investigation.

Abstract
Preclinical infection model systems are extremely valuable tools to aid in our understanding of Human Papillomavirus (HPV) biology, disease progression, prevention, and treatments. In this context, rodent papillomaviruses and their respective infection models are useful tools but remain underutilized resources in the field of papillomavirus biology. Two rodent papillomaviruses, MnPV1, which infects the Mastomys species of multimammate rats, and MmuPV1, which infects laboratory mice, are currently the most studied rodent PVs. Both of these viruses cause malignancy in the skin and can provide attractive infection models to study the lesser understood cutaneous papillomaviruses that have been frequently associated with HPV-related skin cancers. Of these, MmuPV1 is the first reported rodent papillomavirus that can naturally infect the laboratory strain of mice. MmuPV1 is an attractive model virus to study papillomavirus pathogenesis because of the ubiquitous availability of lab mice and the fact that this mouse species is genetically modifiable. In this review, we have summarized the knowledge we have gained about PV biology from the study of rodent papillomaviruses and point out the remaining gaps that can provide new research opportunities.

Abstract
Papillomaviruses (PVs) are small, non-enveloped DNA viruses that cause mucocutaneous tumours including squamous cell carcinoma (SCC) in man. In animals, evidence supports a causal role for PVs in the development of cutaneous and oral SCC in some species. In reptiles, three cases of papilloma or fibropapilloma have been associated with PV infection, but no association has been reported to date with SCC. Two cases of cutaneous epithelial tumours, multiple papillomas in a spiny-tailed lizard (Uromastyx acanthinura) and SCC in a Dumeril's boa (Acrantophis dumerili), were investigated by polymerase chain reaction. PV DNA was amplified from samples of both lesions. Typical microscopical features suggestive of PV infection (e.g. the presence of koilocytes) were observed in the lesions from the spiny-tailed lizard. This is the first report of an association between PV and SCC in reptiles. Further studies are needed to better clarify the role of PVs in these species and to characterize the PV strains involved.

Abstract
Squamous cell carcinoma (SCC) is a common malignancy affecting humans and other animals. Papillomaviruses (PVs) are frequently reported as causal agents of cutaneous benign and malignant epithelial lesions in different animal species, but only few studies have investigated their role in ovine SCC. In this study, we explore the possible involvement of the Ovine aries PVs (OaPV1, OaPV2, OaPV3) in cutaneous SCC using an integrated histological and molecular approach. Forty cutaneous SCCs from different anatomical locations of Sardinian sheep and 40 matched non-SCC samples were evaluated histologically and by polymerase chain reaction (PCR) to assess the presence of ovine PVs. In addition, DNA in situ hybridization (ISH) and reverse transcription-polymerase chain reaction (RT-PCR) were carried out to evaluate the cellular localization and viral transcriptional activity, respectively. OaPV3 DNA was detected in 26 of 40 (65%) SCCs and in 12 of 40 (30%) non-SCC samples using PCR. OaPV1 and OaPV2 were not detected. OaPV3 viral DNA was observed by ISH in malignant epithelial squamous cells of 18 of 40 (45%) SCCs. In addition, the viral transcriptional activity was identified in 24 of 40 (60%) SCCs by RT-PCR. Notably, a higher viral positivity was observed in SCCs compared with non-SCC samples. The considerable infection rate of OaPV3 in the most common skin tumor of the sheep suggests that PV could represent a key factor in the onset of ovine SCC.

Abstract
Papillomaviruses (PVs) cause disease in both dogs and cats. In dogs, PVs are thought to cause oral papillomatosis, cutaneous papillomas and canine viral pigmented plaques, whereas PVs have been rarely associated with the development of oral and cutaneous squamous cell carcinomas in this species. In cats, PVs are currently thought to cause oral papillomas, feline viral plaques, Bowenoid in situ carcinomas and feline sarcoids. Furthermore, there is increasing evidence that PVs may also be a cause of cutaneous squamous cell carcinomas and basal cell carcinomas in cats. These diseases are discussed in this review. Additionally, there is a brief overview of PV biology, including how these viruses cause disease. Diagnostic techniques and possible methods to prevent PV infection are also discussed.

Abstract
A 48-yr-old captive white rhinoceros ( Ceratotherium simum ) was euthanized due to old age, pododermatitis, and progressive laminitis of the middle toe of the left fore- and hindlimbs. Severe chronic necrotizing periodontitis and dental loss was diagnosed, although food intake prior to death had not decreased. In addition, extensive ulceration of the tongue was noted. Histologically, squamous cell carcinoma of the tongue was diagnosed with chronic severe ulcerative glossitis. Metastatic lesions were not detected. Clinicians should monitor the oral health of aging rhinoceros due to the occult nature of these lesions.

Abstract
Aside from a handful of notable exceptions, neoplasia is not reported as a major cause of mortality in wild animal populations and often goes undetected. For northern brown bandicoots specifically, there are few reported tumors in the literature and on file in the Australian Registry of Wildlife Health. This report describes a case of squamous cell carcinoma in a northern brown bandicoot (Isoodon macrourus), with metastases to the draining lymph nodes and lung. This neoplasm consisted predominantly of well-differentiated squamous cells and multifocal keratin pearls, with areas possibly consistent with epithelial to mesenchymal transition, as identified by positive immunohistochemical staining by both pancytokeratin (AE1/AE3) and vimentin. Additional investigations were negative for bandicoot papillomatosis carcinomatosis viruses.

Abstract
CASE SUMMARY A 16-year-old, castrated male, feline immunodeficiency virus (FIV)-positive, domestic shorthair cat developed multiple skin lesions. Most of these were Bowenoid carcinoma in situ and contained DNA sequences consistent with Felis catus papillomavirus type 2. Two additional lesions that developed in the skin and subcutaneous tissues between the digital and carpal pads on the left forelimb and right hindlimb were shown by cytology, histology and culture to be caused by Prototheca wickerhamii. These lesions failed to improve in response to systemic therapy treatment with itraconazole, but excision by sharp en bloc resection with follow-up oral itraconazole therapy proved curative for one lesion, although the other lesion recurred, necessitating a second surgery. RELEVANCE AND NOVEL INFORMATION This is only the second reported case of feline protothecosis from Australia and the first case that has been cultured and identified to the species level. Also of great interest was the presence of multiple papillomavirus-associated neoplastic lesions, which may have afforded a portal of entry for the algal pathogen and the cat's positive FIV status; the latter might have impacted on both viral and algal pathogenesis by effects on immunocompetence.

Abstract
Currently, fifteen bovine papillomavirus (BPV) types have been identified and classified into four genera: Deltapapillomavirus, Epsilonpapillomavirus, Dyoxipapillomavirus, and Xipapillomavirus. Here, the complete genome sequence of a new BPV type (BPV 04AC14) recovered from a papillomatous lesion is reported. The genome is 7,282 bp in length and exhibits the classic genetic organization and motifs of the members of Papillomaviridae. Maximum likelihood phylogenetic analyses revealed that BPV 04AC14 clusters with members of the Xipapillomavirus genus. The nucleotide sequence of the L1 capsid protein of the novel BPV is closely related to its counterpart, BPV3, with which it shares 79% similarity. These findings suggest that this virus is a new BPV type of the Xipapillomavirus genus.

Abstract
Papillomaviruses (PV) are associated with benign mucosal and cutaneous epithelial proliferations. In dogs, PV-associated pigmented plaques and papillomas can undergo malignant transformation, but this is rare, and most cases of canine squamous cell carcinoma do not arise from PV-induced precursor lesions. We describe herein the progression of pigmented plaques to invasive and metastatic squamous cell carcinoma associated with 2 canine papillomaviruses (CPV) in 2 related Basenji dogs. Immunohistochemistry for PV antigen revealed strong nuclear immunoreactivity within keratinocytes from pigmented plaques from both dogs, consistent with a productive viral infection. Polymerase chain reaction (PCR) using degenerate primers for the L1 gene revealed PV DNA sequences from 2 different CPVs. In situ hybridization for CPV revealed strong hybridization signals within the pigmented plaques and neoplastic squamous epithelial cells from both dogs. We report here progression of PV-associated pigmented plaques to metastatic squamous cell carcinoma within 2 Basenji dogs associated with 2 different CPVs.

Abstract
Head and neck squamous cell carcinoma (HNSCC) is the most common oral cancer worldwide. Local bone invasion into the maxilla or mandible and metastasis to regional lymph nodes often result in a poor prognosis, decreased quality of life and shortened survival time for HNSCC patients. Poor response to treatment and clinical outcomes are the major concerns in this aggressive cancer. Multiple animal models have been developed to replicate spontaneous HNSCC and investigate genetic alterations and novel therapeutic targets. This review provides an overview of HNSCC as well as the traditional animal models used in HNSCC preclinical research. The value and challenges of each in vivo model are discussed. Similarity between HNSCC in humans and cats and the possibility of using spontaneous feline oral squamous cell carcinoma (FOSCC) as a model for HNSCC in translational research are highlighted.

Abstract
Squamous cell carcinomas (SCCs) are the second most common cancer of the canine oral cavity resulting in significant morbidity and mortality. Recently a dog with multiple oral SCCs that contained a novel papillomavirus (PV) was reported. The aim of the present study was to determine the genome of this novel PV. To do this a short section of PV DNA was amplified from an oral SCC and 'back-to-back' primers were designed. Due to the circular nature of PV DNA, these primers were then used to amplify the remainder of the genome by inverse PCR. The PCR product was sequenced using next generation sequencing and the full genome of the PV, consisting of 8007 bp, was assembled and analysed. As this is the seventeenth PV identified from the domestic dog, the novel PV was designated Canis familiaris papillomavirus (CPV) type 17. Similar to other CPV types, the putative coding regions of CPV-17 were predicted to produce 5 early and 2 late proteins. Phylogenetic analysis of ORF L1 revealed greater than 70% similarity to CPV-2 and CPV-7 and we propose that CPV-17 also be classified as a Taupapillomavirus 1. While it appears CPV-17 is only rarely present in canine oral SCCs, evidence suggests that this PV could influence the development of oral SCCs in this species.

Abstract
We describe numerous pale plaques affecting the inguinal skin of a grey wolf (Canis lupus). Histologically, these were consistent with papillomaviral plaques. Immunohistochemistry confirmed papillomavirus antigens, and partial sequencing of the L1 gene suggests this is a novel papillomavirus most-closely related to Canis familiaris Papillomavirus 5.
