Abstract
Leishmaniasis in wild canids is a vector-borne disease caused in Europe by the protozoan parasite Leishmania infantum. To date, there is limited information on clinical signs and laboratory abnormalities in wolves due to leishmaniasis. The current clinical case report described a female Iberian wolf (Canis lupus signatus) housed in semi-captivity conditions at the Centro del Lobo Ibérico "Félix Rodríguez de la Fuente", in Robledo de Sanabria, Zamora (Spain), with an interdigital ulcerous wound at the right forepaw, hyper-gammaglobulinemia, and abnormal liver blood parameters. Definitive serodiagnosis of leishmaniasis was established using antileishmanial serum antibodies and PCR analysis of different biological samples. A gold-standard anti-L. infantum treatment protocol consisting in subcutaneous meglumine antimoniate and oral allopurinol combination was installed. However, the presence of pain at the site of injection due to meglumine antimoniate administration forced its substitution by oral miltefosine. A progressive reduction of the levels of anti-L. infantum serum antibodies and the concentrations of gamma-globulin fraction was detected after antileishmanial treatment as well as a decline of liver GPT. To our knowledge, this is the first case of leishmaniasis diagnosed in a wolf housed in semi-captivity conditions, with the condition subsequently treated and successfully cured.

Occurrence of Leishmania infantum in Wild Mammals Admitted to Recovery Centers in Spain. Pathogens 2023; 12:1048. [PMID: 37624008 PMCID: PMC10458632 DOI: 10.3390/pathogens12081048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Revised: 08/11/2023] [Accepted: 08/14/2023] [Indexed: 08/26/2023] Open
Abstract
Zoonotic leishmaniasis caused by Leishmania infantum is distributed worldwide and affects humans and domestic and wild mammals. In Europe, specifically in the Mediterranean basin, leishmaniasis is endemic due to the concurrence of the phlebotomine vectors and reservoir mammals, including carnivorous wildlife species and other less studied wild species. In this article, spleen, skin, and eye or oral swabs taken from 134 wild mammals admitted to five wildlife recovery centers in Spain were used. PCR employing fragments of the Repeat region, ITS1, and SSUrRNA were used for detection, and positive samples were processed for sequencing. L. infantum was detected in three out of the nine species analyzed, including European hedgehog, European badger, and red squirrel, with percentages ranging from 11.53 to 35.71%, depending on the species. Most of the species showed higher percentages of positivity in spleen samples than in skin samples. A small number of animals from the remaining six species tested negative, including Algerian hedgehog, stone marten, least weasel, garden dormouse, western polecat, and Egyptian mongoose. Hedgehogs and badgers are good candidates for consideration as epidemiological sentinels and pose a higher risk as potential reservoirs of leishmaniasis based on their percentage of infection and wide distribution.

Abstract
Wild canids, as well as other wild animal species, are largely exposed to bites by ticks and other hematophagous vectors where the features favoring their presence and spread are found in wooded and semi-wooded areas. Much of the information about arthropod-borne infections concerns domestic and companion animals, whereas data about these infections in wild canids are not exhaustive. The present study is a narrative review of the literature concerning vector-borne infections in wild canids, highlighting their role in the epidemiology of arthropod-borne bacteria and protozoa.

Abstract
Leishmaniasis is a neglected tropical parasitic vector-borne disease that has emerged or re-emerged in recent years and is a major health problem. Algeria is a country where leishmaniasis reaches high levels of endemicity. This systematic review and meta-analysis was performed to collect, compile and summarise data on the prevalence of animal leishmaniasis in Algeria. Data were collected from 2004 to 2022 during which a number of 12 papers were published from dogs, cats, hedgehogs, and jackals. A total of 4812 dogs, 388 stray cats, 24 hedgehogs and 2 Jackals were included in this analysis. The diagnosis of leishmaniasis was performed using serological or molecular tests. The overall prevalence in dogs was 21.2 % (95 %CI, 15.7-26.9 %), and in stray cats, hedgehogs and Jackal was, respectively, 25.3 % (95 %CI, 17-36.6 %), 20.8 % (95 %CI, 8.8-40.9 %) and 50 %. This study is a comprehensive epidemiological analysis of canine leishmaniasis in Algeria and will therefore be a useful tool for researchers. Further studies are needed for a better and continuous assessment of the occurrence of this zoonosis. It can also be used to propose or improve appropriate national surveillance programs for these diseases.

Abstract
Mesocarnivores are small- or mid-sized carnivore species that display a variety of ecologies and behaviours. In Europe, wild mesocarnivores are represented by the red fox (Vulpes vulpes), the golden jackal (Canis aureus), the European wildcat (Felis silvestris), the Mustelidae of the genera Meles, Martes, Mustela, Lutra, the invasive species of raccoon dog (Nyctereutes procyonoides), raccoons (Procyon lotor), and American mink (Neogale vison). These abundant animals thrive in various habitats and often develop their activity close to human settlements. Thus, they may play an important role in the introduction, maintenance, and transmission of major parasitic zoonoses and promote bridging infections with domestic animals. Against this background, this article reports and discusses some of the most important endoparasites of wild mesocarnivores living in Europe, on the basis of their actual role as reservoirs, spreaders, or sentinels. The data derived from epizootiological studies in different European countries, and the proven or speculated implications of the detected endoparasites in human and domestic animals' health, are discussed. Through older and recent literature review, the state-of-the-art knowledge on the occurrence and prevalence of the parasites under consideration is presented, showing further, warranted investigations and the need for surveillance and vigilance.

Abstract
Leishmaniasis is a neglected vector-borne parasitic disease caused in Italy only by the species Leishmania infantum of the Leishmania donovani complex, which is the causative agent of the zoonotic visceral leishmaniasis (VL) and the sporadic cutaneous leishmaniasis (CL) in humans, and of the canine leishmaniasis (CanL). The disease is considered endemic in southern, central, and insular Italian regions and recognizes phlebotomine sand flies as vector and dogs as main reservoir. Among northern Italian region, Emilia-Romagna shows peculiar epidemiological situation and recent studies are questioning the role of dog as main reservoir of L. infantum. Due to their synanthropic relationship with humans, rodents have been tested for Leishmania spp. in several European countries. The aim of this study was to assess the presence of Leishmania spp. in peridomestic rodents in the Emilia-Romagna. The study was carried out on 136 peridomestic rodents collected by professional pest control services: 47 brown rats (Rattus norvegicus), 39 black rats (Rattus rattus) and 50 mice (Mus musculus). Specimens of earlobe skin, spleen, liver and prescapular lymph nodes were tested with a real-time PCR. Fifteen (11%) rodents, tested positive for Leishmania spp. in particular five brown rats (10.6%), five black rats (12.8%) and five mice (10%). Positivity was obtained from different target organs. These findings revealed the presence of Leishmania spp. in peridomestic rodents of Emilia-Romagna Region, also in two species never tested before in Italy, namely R. norvegicus and M. musculus.

Abstract
In the last decade, an upsurge of human leishmaniasis has been reported in the Emilia-Romagna region, Northeast Italy. Epidemiologic data have raised doubts about the role of dogs as the main reservoirs for Leishmania infantum. In the present study, a total of 1,077 wild animals were screened for L. infantum DNA in earlobe and spleen samples from 2019 to 2022. The lymph nodes were tested only in 23 animals already positive in the earlobe and/or spleen. A total of 71 (6.6%) animals resulted positive in at least one of the sampled tissues, including 3/18 (16.7%) wolves, 6/39 (15.4%) European hares, 38/309 (12.3%) roe deer, 1/11 (9.1%) red deer, 8/146 (4.9%) wild boars, 13/319 (4.1%) red foxes, 1/54 (1.9%) porcupine, and 1/59 (1.7%) European badger. Most of the infected animals (62/71) tested positive only in the earlobe tissue, only four animals (two roe deer and two wild boars) tested positive only in the spleen, and five animals (three roe deer and two red foxes) resulted positive for both tissues. L. infantum DNA was detected in the lymph nodes of 6/23 animals. L. infantum detection occurred in all seasons associated with low real-time PCR Ct values. Further research is needed in order to clarify the role of wildlife in the re-emerging focus of leishmaniasis in Northeast Italy.

Abstract
In the last decades, wildlife diseases and the health status of animal populations have gained increasing attention from the scientific community as part of a One Health framework. Furthermore, the need for non-invasive sampling methods with a minimal impact on wildlife has become paramount in complying with modern ethical standards and regulations, and to collect high-quality and unbiased data. We analysed the publication trends on non-invasive sampling in wildlife health and disease research and offer a comprehensive review on the different samples that can be collected non-invasively. We retrieved 272 articles spanning from 1998 to 2021, with a rapid increase in number from 2010. Thirty-nine percent of the papers were focussed on diseases, 58% on other health-related topics, and 3% on both. Stress and other physiological parameters were the most addressed research topics, followed by viruses, helminths, and bacterial infections. Terrestrial mammals accounted for 75% of all publications, and faeces were the most widely used sample. Our review of the sampling materials and collection methods highlights that, although the use of some types of samples for specific applications is now consolidated, others are perhaps still underutilised and new technologies may offer future opportunities for an even wider use of non-invasively collected samples.

INTERNATIONAL JOURNAL FOR PARASITOLOGY-PARASITES AND WILDLIFE 2021; 16:217-227. [PMID: 34703761 PMCID: PMC8524744 DOI: 10.1016/j.ijppaw.2021.10.005] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/02/2021] [Revised: 10/09/2021] [Accepted: 10/09/2021] [Indexed: 12/04/2022]
Abstract
The European hedgehog population is declining in Europe. It is therefore important to investigate the causes for the decline and monitor the general health of the species. We investigated the endoparasite occurrence in 299 dead European hedgehogs. Of these, endoparasites were detected in 69% of the individuals tested. We identified Crenosoma striatum, Capillaria aerophila (syn. Eucoleus aerophilus), Capillaria spp., coccidia, Cryptosporidium spp., Brachylaemus spp. and Capillaria hepatica. We also examined the hedgehogs for Giardia spp. and Echinococcus multilocularis but all were negative. Coccidia (n = 7, 2.5%) and Cryptosporidium spp. (n = 14, 5.2%) were only detected in individuals from Zealand, Lolland and Jutland south of the Limfjord. Single cases of Brachylaemus spp. (n = 1, 0.4%) and Capillaria hepatica (n = 1, 1.1%) were exclusively discovered in Jutland south and north of the Limfjord, respectively. These results indicate a regional difference in endoparasite species carried by European hedgehogs in Denmark. This stresses the need for hedgehogs to be cared for locally when admitted to wildlife rehabilitation centres, and to be released within their area of origin, to prevent spread of endoparasite infections among hedgehogs. Additionally, we explored the following possible determinants of parasite infection in the hedgehogs: sex, age, mortality category (in-care, natural and roadkill), infection with MRSA, genetic heterozygosity, month of death, geographical location and habitat type, and found that only age had a statistically significant effect on endoparasite prevalence, as we detected a lower occurrence of endoparasites in juvenile hedgehogs (<1 year) compared to the other age classes. However, pairwise comparisons of geographical regions did show significant differences in endoparasite occurrence: Zealand vs. Jutland south of the Limfjord and Zealand vs. Falster. We conclude that, in line with previous studies of European hedgehogs throughout their range in Western Europe, endoparasite infections are common and a natural part of their ecology. We investigated the endoparasites of 299 dead European hedgehogs from Denmark. We found that 69% (n = 206) of the hedgehogs hosted endoparasites. We detected Crenosoma, Capillaria, Cryptosporidium, Brachylaemus and coccidia spp. We explored possible determinants of overall endoparasite occurrence. We conclude that only age and geography significantly affected endoparasite occurrence.

Abstract
Leishmaniosis infection begins when a phlebotomine sand fly vector inoculates pathogenic protozoan parasites of the genus Leishmania into a mammalian host. In the case of Leishmania infantum, the domestic dog is considered to be the main parasite reservoir, and canine leishmaniosis (CanL) has a high mortality rate in untreated dogs. Hundreds of cases of human leishmaniosis (HL) are reported in the world each year, the incidence in Europe being relatively low. Leishmaniosis control is primarily focused on the dog, combining methods that prevent sand fly bites and boost host resistance to infection. However, these measures are only partially effective and new solutions need to be found. One of the main factors limiting CanL and HL control is the existence of a sylvatic Leishmania transmission cycle that interacts with the domestic cycle maintained by dogs. It is suspected that the main reservoir of infection in wildlife are rodents, whose expansion and rapid population growth worldwide is increasing the risk of human and zoonotic pathogen transfer. The aim of this review is therefore to analyze reports in the literature that may shed light on the potential role of rodents in the leishmaniosis transmission cycle in the Mediterranean area. Following the general methodology recommended for reviews, six databases (Google Scholar, Ovid, PubMed, Science Direct, Scopus and Web of Science) were explored for the period January 1995 to December 2020. The results extracted from 39 publications that met the established inclusion criteria were analyzed. It was found that 23 species of rodents have been studied in nine countries of the Mediterranean basin. Of the 3,643 specimens studied, 302 tested positive for L. infantum infection by serology, microscopy and/or molecular techniques.

Invasive Species as Hosts of Zoonotic Infections: The Case of American Mink ( Neovison vison) and Leishmania infantum. Microorganisms 2021; 9:microorganisms9071531. [PMID: 34361966 PMCID: PMC8304841 DOI: 10.3390/microorganisms9071531] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2021] [Revised: 07/09/2021] [Accepted: 07/14/2021] [Indexed: 01/29/2023] Open
Abstract
Leishmania infantum produces an endemic disease in the Mediterranean Basin that affects humans and domestic and wild mammals, which can act as reservoir or minor host. In this study, we analyzed the presence of the parasite in wild American minks, an invasive species in Spain. We screened for L. infantum DNA by PCR using five primer pairs: Two targeting kinetoplast DNA (kDNA), and the rest targeting the ITS1 region, the small subunit of ribosomal RNA (SSU) and a repetitive sequence (Repeat region). The detection limit was determined for each method using a strain of L. infantum and a bone marrow sample from an infected dog. PCR approaches employing the Repeat region and kDNA (RV1/RV2 primers) showed higher sensitivity than the other PCR methods when control samples were employed. However, only PCR of the Repeat region and nested PCR of SSU (LnSSU) detected the parasite in the samples, while the other three were unable to do so. The majority of the analyzed animals (90.1%) tested positive. American mink may act as an incidental host of the disease for other mammals and should be further investigated, not only for their negative impact on the local fauna, but also as carriers of zoonotic diseases.

Abstract
The aetiology and epidemiology of vector borne apicomplexan Babesia and Hepatozoon and kinetoplastid Leishmania infantum infections in wildlife have not been explored in wide areas of southern Spain. We investigated these infections in 151 wild carnivores, including foxes, badgers, beech martens, hedgehogs, wild cats, Egyptian mongooses, otters, genets and racoons. Overall, Hepatozoon, Babesia and L. infantum infections were detected in 68%, 48% and 23% of the wild animals surveyed, respectively. L. infantum-infected wildlife were more likely to be also infected with the apicomplexan Hepatozoon and Babesia spp. compared to the non-infected counterparts (p < .05). We report for the first time Hepatozoon martis in badgers and wild cats and H. canis in beech martens, and a Babesia sp. in wild cats from Spain. Our results also indicate the widespread distribution of H. canis in foxes (91%) and beech martens (13%), H. martis in beech martens (81%), wild cats (20%) and badgers (13%), H. felis in wild cats (60%), B. vulpes in foxes (64%), Babesia sp. type A closely related to B. vulpes, in badgers (58%) and Babesia sp. in wild cats (20%). Moreover, L. infantum infection was found in foxes (29%), beech martens (13%), badgers (8%) and 1/3 Egyptian mongooses. We also detected Cytauxzoon sp. in a wild cat and the first Sarcocystis sp. in a genet. This study provided evidence of increased risk of L. infantum infection in wildlife animals co-infected with Babesia spp. or Hepatozoon spp. and indicated that these infections are widespread in wild carnivores from Spanish Mediterranean ecosystems.

Abstract
Erinaceus europaeus is a cosmopolitan mammalian species broadly distributed in Europe, from natural to suburban areas. Due to its ecological role and susceptibility to distinct zoonotic agents, E. europaeus could be a suitable sentinel candidate for many global problems that negatively affect human and animal health. Hedgehogs can work as bioindicators to environmental contamination and can be hosts for multiple tickborne zoonotic agents. Thus, people who directly or indirectly make physical contact with this species are exposed to a variety of threats. Moreover, it has also been studied as an indicator for antibiotic resistance, which was already confirmed for tetracyclines. Additionally, it was also reported as a reservoir for methicillin-resistant Staphylococcus aureus (MRSA). More recently, hedgehogs have been recently recognised as potential reservoirs of MERS-CoV-like strains. Among other animals, this species can possibly represent an intermediate reservoir for SARS-CoV-2. The aim of this review is to briefly expose the scientific attainments about hedgehog health, namely agents, diseases, and threats that significantly affect general health concerns and that contribute to achieve One Health principles.

Abstract
Leishmaniasis are neglected diseases caused by several species of Leishmania that affect humans and many domestic and wild animals with a worldwide distribution. The objectives of this review are to identify wild animals naturally infected with zoonotic Leishmania species as well as the organs infected, methods employed for detection and percentage of infection. A literature search starting from 1990 was performed following the PRISMA methodology and 161 reports were included. One hundred and eighty-nine species from ten orders (i.e., Carnivora, Chiroptera, Cingulata, Didelphimorphia, Diprotodontia, Lagomorpha, Eulipotyphla, Pilosa, Primates and Rodentia) were reported to be infected, and a few animals were classified only at the genus level. An exhaustive list of species; diagnostic techniques, including PCR targets; infected organs; number of animals explored and percentage of positives are presented. L. infantum infection was described in 98 wild species and L. (Viania) spp. in 52 wild animals, while L. mexicana, L. amazonensis, L. major and L. tropica were described in fewer than 32 animals each. During the last decade, intense research revealed new hosts within Chiroptera and Lagomorpha. Carnivores and rodents were the most relevant hosts for L. infantum and L. (Viannia) spp., with some species showing lesions, although in most of the studies clinical signs were not reported.

Abstract
Infection with Leishmania parasites can lead to severe disease in humans and dogs, which act as a reservoir in zoonotic transmission. An increasing number of reports suggest that leishmaniosis is not restricted to dogs, but also affects many other mammalian and avian species. Consequently, this expands the potential reservoir and is of great public and veterinary health concern. The present study reviews, based on a comprehensive search of scientific literature published from 1 January 2001 to 31 December 2020, the currently available information on animal leishmaniosis in vertebrates in Europe, other than dogs and humans. This review provides an exhaustive list of mammals and birds in which infections with or exposure to Leishmania parasites have been detected in European countries. Most cases are reported from the Mediterranean region. Domestic animals, in particular cats, pose a concern because of close contact with humans. The wildlife reservoir is less likely to contribute to zoonotic transmission, with the exception of hares. This potentially large reservoir needs to be taken into account when developing control measures for zoonotic leishmaniosis. From a veterinary point of view, it is important that veterinarians are better aware of leishmaniosis and trained in its management.

Abstract
Malaria has been for millennia one of the best known and most destructive diseases affecting humans. Its high impact has aroused great interest for the development of new effective and reliable diagnostic techniques. Recently it has been recently published that hairs from mammal hosts are able to capture, hold and finally remove foreign DNA sequences of Leishmania parasites. The aim of this study was to check if Plasmodium falciparum (P. falciparum) DNA remains stable in blood samples deposited in Whatman paper after suffering different transport and storage conditions, and to compare the sensitivity of these results with those offered by thick a smear and Rapid Diagnostic Test, and besides to examine whether P. falciparum DNA would be detected and quantified by Real time quantitative PCR (qPCR) from hairs of people with different types of malaria. P. falciparum Histidine Repeat Protein II (pHRP-II) antigen detection and P. falciparum DNA were detected in 18 of 19 dry blood samples adhered to Whatman paper (94.74%), besides, Plasmodium DNA was also detected in seven out of 19 hair samples analyzed (36.84%), remaining stable until analysis for several months under the exposure to different environmental conditions. Although the sensitivity of PCR for the diagnosis of malaria in hair samples is not as high as blood analysis, the study of Plasmodium DNA presence in blood and hair could constitute a complementary tool with numerous advantages in sample collection, transport and storage. We suggest that the method could be also applied to medical, forensic and paleo-parasitological diagnosis, not only for malaria but also for searching many other pathogens in hair samples.

Abstract
Leishmania infantum is a protozoan causing leishmaniasis in humans and in dogs, among other animals, which is an endemic disease in the Mediterranean basin. In recent years, the role of wildlife as a possible reservoir of the disease was analyzed and several species of carnivores were reported to have the highest infection rates, with foxes and wolves being the more widely studied species; the role of rabbits and hares as reservoirs of leishmaniasis has also been described. In addition, several studies highlighted the role of bats as suitable hosts for Leishmania species (L. braziliensis, L. major, L. mexicana, and L. tropica) in South and Central America and Africa, but no Leishmania spp. infection in Chiroptera has been reported in Europe. In this study, samples from spleen, hair, and blood were analyzed to detect L. infantum DNA in bats from the Community of Madrid (Spain). Infection by L. infantum was detected in 59.2% of the bats studied (n = 16/27), with the spleen being selected as the site for detection, yielding 14/16 positive results (87.5% sensitivity), followed by hair (n = 7/16) and blood (n = 6/16). In two animals, samples from all three anatomical sites tested positive (7.4% of the total animals), while in four animals the spleen and hair samples tested positive (14.8%), in one animal the blood and hair samples tested positive (3.7%), and in another animal the blood sample only tested positive (3.7%). This is the first report of L. infantum detection in the common urban bat (Pipistrellus pipistrellus) in Europe.

Noninvasive Biological Samples to Detect and Diagnose Infections due to Trypanosomatidae Parasites: A Systematic Review and Meta-Analysis. Int J Mol Sci 2020; 21:E1684.

Abstract
Unicellular eukaryotes of the Trypanosomatidae family include human and animal pathogens that belong to the Trypanosoma and Leishmania genera. Diagnosis of the diseases they cause requires the sampling of body fluids (e.g., blood, lymph, peritoneal fluid, cerebrospinal fluid) or organ biopsies (e.g., bone marrow, spleen), which are mostly obtained through invasive methods. Body fluids or appendages can be alternatives to these invasive biopsies but appropriateness remains poorly studied. To further address this question, we perform a systematic review on clues evidencing the presence of parasites, genetic material, antibodies, and antigens in body secretions, appendages, or the organs or proximal tissues that produce these materials. Paper selection was based on searches in PubMed, Web of Science, WorldWideScience, SciELO, Embase, and Google. The information of each selected article (n = 333) was classified into different sections and data were extracted from 77 papers. The presence of Trypanosomatidae parasites has been tracked in most of organs or proximal tissues that produce body secretions or appendages, in naturally or experimentally infected hosts. The meta-analysis highlights the paucity of studies on human African trypanosomiasis and an absence on animal trypanosomiasis. Among the collected data high heterogeneity in terms of the I2 statistic (100%) is recorded. A high positivity is recorded for antibody and genetic material detection in urine of patients and dogs suffering leishmaniasis, and of antigens for leishmaniasis and Chagas disease. Data on conjunctival swabs can be analyzed with molecular methods solely for dogs suffering canine visceral leishmaniasis. Saliva and hair/bristles showed a pretty good positivity that support their potential to be used for leishmaniasis diagnosis. In conclusion, our study pinpoints significant gaps that need to be filled in order to properly address the interest of body secretion and hair or bristles for the diagnosis of infections caused by Leishmania and by other Trypanosomatidae parasites.

Prev Vet Med 2019; 175:104874. [PMID: 31901603 DOI: 10.1016/j.prevetmed.2019.104874] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2019] [Revised: 11/13/2019] [Accepted: 12/17/2019] [Indexed: 01/17/2023]
Abstract
A molecular survey of wild mammals was performed to assess their potential as reservoirs of L. infantum. A total of 156 specimens of wild mammalian fauna were obtained for analysis from areas in Catalonia with a reported incidence of canine leishmaniasis. They consisted of 124 small mammals: 35 Mus spretus (Muridae); 64 Erinaceus europaeus (Erinaceidae), 25 Sciurus vulgaris (Sciuridae) and 32 carnivores: 11 Vulpes vulpes (Canidae), 1 Felis catus (Felidae), 15 Meles meles, 4 Martes foina and 1 Mustela vison (Mustelidae). The analysis was performed on samples of liver, spleen, skin (ear) and blood extracted from the heart. Leishmania DNA was determined by a qPCR and specific anti-Leishmania antibodies were detected by an in-house (ELISA). Among the 156 specimens studied, 29.48% were positive in at least one of the samples studied and considered infected. In M. spretus, Leishmania DNA was detected in the liver, spleen or skin of 37.1% of 35 specimens, and 2 of the 13 specimens tested serologically were positive (15.38%). In E. europaeus, 34.4% of the 64 specimens were infected. Leishmania DNA was detected in 19/51 spleens and 5/50 skins; 2 of the 37 specimens analysed in both spleen and skin gave positive results in both samples. Serology was positive in 12.8% (6/47) by ELISA; 3 specimens were positive by both ELISA and qPCR. In S. vulgaris, Leishmania DNA was detected in 5 of 25 specimens (20%). Of the 32 carnivore specimens analysed, Leishmania DNA was detected in both samples studied (spleen and liver) of 4 (12.5%) (2 M. foina, 1 M. vison and 1 F. catus), which were not studied serologically. The data obtained indicate that small mammals, above all wild rodents and carnivores, could act as naturally infected hosts of L. infantum in this endemic area. Among the rodents, M. spretus stands out with the highest prevalence of infection. In E. europaeus, the presence of L. infantum DNA in spleen and skin, and antibodies in heart blood, reported here for the first time, indicates this small mammal could be a possible reservoir. Additionally, S. vulgaris, not previously studied as an L. infantum reservoir, showed non-negligible prevalence values, indicating a potential role in leishmaniasis transmission.

Serological evidence of Leishmania infection by employing ELISA and rapid tests in captive felids and canids in Brazil. VETERINARY PARASITOLOGY- REGIONAL STUDIES AND REPORTS 2019; 17:100308. [PMID: 31303228 DOI: 10.1016/j.vprsr.2019.100308] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/22/2018] [Revised: 05/23/2019] [Accepted: 05/28/2019] [Indexed: 11/23/2022]
Abstract
Visceral leishmaniasis (VL) is a zoonosis and the dog is considered the most important urban reservoir. Cases in cats have been reported, but little is known about Leishmania infection and disease in wild felids and canids kept in captivity in endemic areas. Thus, the serological pattern of wild felids and canids kept in captivity at the Belo Horizonte Zoological Garden was investigated using two primary antigens for conventional ELISA: k39 and rKDDR, as well as three serological rapid kits: Dual Path Platform (DPP®) immunochromatographic test, rKDDR Immunochromatographic assay and ELISA SNAP Leishmania IDEXX®. A total of 21 serum samples, 13 of wild felids and 8 wild canids of varying age and sex were evaluated. The results obtained in the tests were analyzed by agreement using Kappa coefficient, and between ELISA antigens all the analysis performed had showed significant agreement among both of them, as well between the three immunochromatographic tests. The results demonstrated that there is serological evidence of wild animals seropositive for Leishmania antibodies at the Belo Horizonte Zoological Garden, and that all the antigens and rapid tests used can be employed in serological screening for VL in wild felids and canids.

Abstract
Visceral leishmaniosis (VL) remains a serious public health problem in Brazil. Dogs are the main hosts of the parasite, developing canine leishmaniosis (CanL), hence the importance of an accurate diagnosis of the animals. Recently, the application of qPCR method to non-invasive samples obtained from dogs with CanL has shown high sensitivity. Thus, we analyzed by qPCR blood, hair (from healthy zones and cutaneous lesions) and cerumen of 16 dogs with confirmed leishmaniosis from Araçatuba, a Brazilian endemic area. Cerumen-qPCR showed the highest sensitivity (87.5%), followed by hair (lesions: 78.57%, healthy skin: 62.5%), and blood (68.75%). We also analyzed blood, hair and cerumen of 5 healthy dogs from a non-endemic area, obtaining 100% of specificity in all samples. The use of cerumen and hair for qPCR analysis provides high reliability, taking into account the sensitivity and total specificity of the method. The non-invasive sampling procedure without the need of specific conditions of storage and transport support the usefulness of hair and cerumen for the diagnosis of CanL.

Abstract
The diagnosis of leishmaniasis relies mainly on the use of invasive processes, to collect the biological material for detecting Leishmania parasites. Body fluids, which can be collected by non-invasive process, would greatly facilitate the leishmaniasis diagnosis. In the present study, we investigated the potency of urine immunoblotting to diagnose cutaneous and visceral leishmaniasis and we compared with routine molecular methods. A total of 80 samples, including 40 sera and their 40 corresponding urine samples were collected from 37 suspected patients with cutaneous and visceral leishmaniasis, and 3 healthy individuals (as control), in Ilam and Ardabil provinces of Iran. All sera and urine samples were analyzed, using immunoblotting. The confirmation of leishmaniasis infection was performed, using conventional and quantitative PCRs as well as by sequencing the amplicons. Among 37 suspected patients, 23 patients presented cutaneous lesions (CL) and 14 exhibited clinical symptoms reminiscent of visceral leishmaniasis (L. infantum). Among cutaneous patients, 15 were positive for zoonotic cutaneous leishmaniasis (L. major), and eight for anthroponotic cutaneous leishmaniasis (L. tropica). Molecular quantification of Leishmania parasites was performed on sera, urines and cutaneous biopsies of CL and VL patients, demonstrating that parasite load is lower in urines, compared to sera or biopsy. DNA can be detected in 20 out of 23 (86.9%) CL urine samples and in 13 out of 14 (92.8%) VL urine samples. Immunodetection analysis demonstrates that 22 out of 23 (95.6%) sera from CL patients and all patients suspected with VL are positive. For urine samples, 18 out of 23 (78.2%) urine of CL patients and 13 out of 14 (92.8%) urine of VL patients were positive, using Western blot. Therefore, immunodetection and molecular analysis using urine samples can be used as a diagnostic tool for surveying cutaneous and visceral leishmaniasis.

Abstract
Leishmaniasis is a vector-borne disease caused by many Leishmania species, which can infect both humans and other mammals. Leishmaniasis is a complex disease, with heterogeneous clinical manifestations ranging from asymptomatic infections to lesions at cutaneous sites (cutaneous leishmaniasis), mucosal sites (mucocutaneous leishmaniasis) or in visceral organs (visceral leishmaniasis), depending on the species and host characteristics. Often, symptoms are inconclusive and leishmaniasis can be confused with other co-endemic diseases. Moreover, co-infections (mainly with HIV in humans) can produce atypical clinical presentations. A correct diagnosis is crucial to apply the appropriate treatment and the use of molecular techniques in diagnosis of leishmaniasis has become increasingly relevant due to their remarkable sensitivity, specificity and possible application to a variety of clinical samples. Among them, real-time PCR (qPCR)-based approaches have become increasingly popular in the last years not only for detection and quantification of Leishmania species but also for species identification. However, despite qPCR-based methods having proven to be very effective in the diagnosis of leishmaniasis, a standardized method does not exist. This review summarizes the qPCR-based methods in the diagnosis of leishmaniasis focusing on the recent developments and applications in this field.

Abstract
In Pakistan leishmaniasis occurs periodically throughout the year and various out breaks are reported frequently. In continuation of our research on this neglected disease, the aim of present study is to explore: (1) the prevalence of cutaneous leishmaniasis in school boys; (2) Leishmania species identification in order to epidemiology and dynamics of the disease; (3) Identification of risk factors for Leishmaniasis especially for CL. The data was collected in August 2014 The experimental strategy involved a questionnaire for data collection and along with clinical diagnosis of 134 out of 9368 students for incidence of Leishmania spp. in 7 square kilometres area in the schoolboys at Tehsil Landi Kotal, District Khyber Agency, FATA Pakistan. The parasitological and molecular diagnosis of clinically suspected cutaneous leishmaniasis cases were performed using microscopical examination of Giemsa-stained smears of lesion exudates and minicircle kDNA semi nested PCR, respectively. Microscopy (x=1000) positive cases were 84/134 (62.6%) and 50/134 (37.4%) slides did not showed any presence of amastigotes of Leishmania spp. The samples were amplified using kDNA semi nested PCR and confirmed the presence of L. Tropica (Ac.no KT 985473). PCR positive cases were 97/134 (72.4%) and 37(27.6%) were negative. The prevalence of L. tropica in school boys was 1.4% (134/9368) in the total population studied (n=9368). The parasite prevalence might be greater as only male students were considered in the study due to ethical and social issues and limitations.

Abstract
Diagnosis of infection with Leishmania infantum by DNA detection in the hair has been recently demonstrated in dogs and wild animals. Our objective was to investigate if polymerase chain reaction (PCR) in hair might be used to identify infectious dogs. Thus, we assessed the infectiousness to Lutzomyia longipalpis by xenodiagnosis in comparison with the detection of L. infantum DNA by PCR in the hair, and with serology for anti-Leishmania IgG by ELISA in 15 positive dogs for L. infantum infection. Eight healthy dogs were included as negative controls. Among the 15 infected dogs, 13 were found positive in the ELISA (87%), 12 were PCR positive in the hair (80%), and 10 were positive in xenodiagnosis (67%). Positivity in the hair was associated with positivity in spleen (p=0.0003), seropositivity for antibodies (p=0.0006) and parasite transmission to L. longipalpis (p=0.0028). Considering the benefits to animal welfare and feasibility of hair sampling method, studies in larger and more diverse populations of naturally infected dogs from endemic areas should be conducted to evaluate the sensitivity, specificity, and predictive values of PCR using hair as a possible biomarker of infectiousness in dogs.

Abstract
In Tunisia, Leishmania parasites are responsible of visceral leishmaniasis, caused by Leishmania infantum species while three cutaneous disease forms are documented: chronic cutaneous leishmaniasis due to Leishmania killicki, sporadic cutaneous form (SCL) caused by L. infantum and the predominant zoonotic cutaneous leishmanaisis (ZCL) due to Leishmania major. ZCL reservoirs are rodents of the Psammomys and Meriones genera, while for SCL the dog is supposed to be a reservoir. Ctenodactylus gundii is involved in the transmission of L. killicki. However, other mammals could constitute potential reservoir hosts in Tunisia and other North African countries. In order to explore the role of hedgehogs as potential reservoirs of leishmaniasis, specimens (N=6) were captured during July-November period in 2011-2013 in an SCL endemic area in El Kef region, North-Western Tunisia. Using morphological characteristics, all specimens were described and measured. Biopsies from liver, heart, kidney and spleen of each animal were used to extract genomic DNA, which was further used in PCR assays to assess the presence of Leishmania parasites. Different PCRs targeting kinetoplast minicircles, ITS1, mini-exon genes and a repetitive Leishmania- specific sequence, were applied. To further identify Leishmania species involved, RFLP analysis of amplified fragments was performed with appropriate restriction enzymes. Using morphological characters, animals were identified as North African hedgehogs, also called Algerian hedgehogs, that belong to the Erinaceidae family, genus Atelerix Pomel 1848, and species algirus (Lereboullet, 1842). PCR results showed in total that all specimens were Leishmania infected, with different organs incriminated, mainly liver and spleen. Results were confirmed by direct sequencing of amplified fragments. Species identification showed that all specimens were infected with L. major, three of which were additionally co-infected with L. infantum. The present study demonstrates, for the first time in Tunisia, natural infection of hedgehog animals (Atelerix algirus) by the Leishmania parasites species L. major and L. infantum. L. major is also detected for the first time in wild animals captured in the North Western part of the country; likewise for the co-infection of these animals by the 2 Leishmania species. This mammal could play a potential reservoir role in epidemiology of SCL or ZCL and could contribute to emergence or extension of ZCL in the studied region.

Abstract
Leishmania (Leishmania) infantum is the cause of visceral leishmaniasis in the Americas. The disease is transmitted mostly through the bite of the invertebrate vector, the phlebotomine Lutzomyia longipalpis in the New World. Although the domestic dog is considered the most important reservoir of the disease, other mammalian, including wildlife, are susceptible to infection. The goal of this study was to perform xenodiagnosis to evaluate the capacity of naturally infected maned wolves (Chrysocyon brachyurus) and bush dogs (Speothos venaticus) to transmit Leishmania infantum to female sand flies (L. longipalpis). Xenodiagnoses were performed in February and August, 2013, when 77.7% (three maned wolves and four bush dogs) or 100% of the animals were positive, respectively. However, parasite loads in the engorged sand flies was low (<200 promastigotes and <150.2 parasites/μg of DNA). No statistically significant differences were observed between the two species or the two time points (February and August). In conclusion, this study demonstrated that maned wolves (C. brachyurus) and bush dogs (S. venaticus) asymptomatically infected with L. infantum are capable of transmitting L. infantum to the invertebrate host L. longipalpis, although the parasite loads in engorged phlebotomines exposed to these animals were very low.

First report of natural infection in hedgehogs with Leishmania major, a possible reservoir of zoonotic cutaneous leishmaniasis in Algeria. Acta Trop 2014; 135:44-9.

Abstract
We report here the first known cases of natural infection of hedgehogs with Leishmania major. Cutaneous leishmaniasis is an important public health problem in the area of M'sila, a semi-arid province in Algeria's northern Sahara, where two species of hedgehog live, Atelerix algirus and Paraechinus aethiopicus. The aim of this research was to survey Leishmania infection in these hedgehogs and evaluate whether they were reservoir hosts of Leishmania in an endemic zoonotic focus of leishmaniasis. Serological and molecular methods were used to determine the presence of Leishmania in 24 hedgehogs caught directly by hand and identified at species level as 19 A. algirus and 5 P. aethiopicus. Specific anti-Leishmania antibodies were detected in 29.2% of individuals by Western blot and in 26.3% by ELISA. The real-time PCR performed in spleen, ear and blood samples detected Leishmania spp. DNA in 12.5% of the individuals, one A. algirus and two P. aethiopicus. Three skin and two spleen samples of these animals were found to be parasitized and were identified by molecular test as L. major. Considering our results, it is suggested that hedgehogs have a potential epidemiological role as reservoir hosts of L. major.

Abstract
Visceral leishmaniasis (VL) is an emerging zoonosis caused by Leishmania (Leishmania) infantum. Although the domestic dog is the main vertebrate host, many zoo and wild mammal species have been diagnosed with L. infantum infection, especially in endemic areas. There are many available diagnostic approaches, including serological, parasitological and molecular tests. Among wild animals, carnivores and primates are more often clinically affected, with some species, such as the bush dog (Speothos venaticus) being especially susceptible to development of clinical signs. There are also reports and research articles of VL in felids, rodents, and marsupials. This work aims to review the occurrence of VL in zoo and wildlife and raise awareness of its importance in the field of conservational veterinary medicine.
