[PMID: 39823715 DOI: 10.1016/j.vetmic.2025.110390] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2024] [Revised: 01/08/2025] [Accepted: 01/11/2025] [Indexed: 01/20/2025]
Abstract
Although wild and domestic carnivores share some haemotropic Mycoplasma species, information about the circulation of this pathogen in grey wolves (Canis lupus) populations is still very limited. Thus, a geographically broad-based investigation was performed for determining the occurrence and diversity of Mycoplasma spp. in three different wolf populations from southern Europe. Between 2001 and 2023, spleen samples from 285 grey wolves from Spain (n = 129), Italy (n = 113), and Portugal (n = 43) were collected. The presence of haemotropic Mycoplasma was assessed targeting the 16S rRNA gene using two PCR assays in parallel; in addition, the 16S-23S rRNA intergenic spacer was analysed for further identification of the positive samples. The influence of the sampling country, sex, and age of the animals on the prevalence of Mycoplasma spp. was also assessed by a generalized linear model analysis. The percentage of positive wolves was 13.3 % (38/285), and the occurrence was significantly higher in Spain (20.9 %) than in Italy (8.0 %) and Portugal (4.7 %). Mycoplasma haemocanis (10.5 %) and Candidatus M. haematoparvum (2.1 %), were identified; in addition, an uncultured Mycoplasma sp. was also detected (0.7 %). Our results confirm the circulation of potentially zoonotic Mycoplasma in wolf populations from southern Europe. To our knowledge, this is the first report of Ca. M. haematoparvum in wolves from Italy and Portugal. In addition, a Mycoplasma sp., previously found in dogs, has been detected for the first time in wolves. Further studies are needed to fully molecularly characterise haemotropic Mycoplasma spp., which will serve as a basis for the study of its ecoepidemiology.

Shi H, Li G, Li D, Zhai H, Ji S, Hu Y, Wang L, Yao L. Molecular investigation reveals three hemotropic mycoplasmas in cats and three tick species in China. Front Vet Sci 2025; 12:1522904. [PMID: 39950087 PMCID: PMC11821626 DOI: 10.3389/fvets.2025.1522904] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2024] [Accepted: 01/06/2025] [Indexed: 02/16/2025] Open
Abstract
To date, the primary hemoplasmas that infect cats include Mycoplasma haemofelis, 'Candidatus Mycoplasma haemominutum', and 'Candidatus Mycoplasma turicensis'. In addition, other hemoplasmas Mycoplasma species have also been identified in cats. In central China, no infections or potential vectors with hemotropic mycoplasmas have been recorded in cats. To elucidate the prevalence of hemotropic mycoplasmas in both cats and parasitic ticks, this study investigated the occurrence of hemotropic mycoplasma infections in ticks and cats. A total of 78 blood samples were collected from both anemic and healthy cats, along with 284 ticks from the cats' body surfaces and 356 ticks found in the surrounding environment. Following the morphological and molecular identification of ticks, all samples were screened for pathogens using PCR detection and sequence analysis. The results indicated the presence of 392 Haemaphysalis longicornis, 152 Rhipicephalus microplus, and 76 Rhipicephalus sanguineus sensu lato in cats and their surrounding environment. Molecular detection revealed the amplification of 156 'Ca. M. haemominutum', 96 'Candidatus Mycoplasma haemobos', 41 M. haemofelis, and 64 Rickettsia felis-positive amplicons from both cats and ticks. Notably, when comparing the infection rates of 'Ca. M. haemobos' in the environment group, no significant differences were observed in the infection rates among the three tick species from anemic or healthy cats (p > 0.05, α = 0.05). Furthermore, sequence analysis of 'Ca. M. haemobos' indicated two novel sequence types that were most closely related to an isolate from buffalo in China. In conclusion, in this study, in addition to 'Ca. M. haemominutum' and M. haemofelis, 'Ca. M. haemobos' was first detected in cats. 'Ca. M. haemominutum' appears to be associated with anemic syndrome in cats, while further research is needed to explore the relationship between 'Ca. M. haemobos' and clinical signs in felines. Additionally, these three hemotropic mycoplasmas were also found in three species of ticks, and transmission experiments are required to investigate the capacity of these ticks to transmit hemoplasmas Mycoplasma among animals.

Molecular screening of selected vector-borne pathogens circulating in owned dogs in the Caribbean archipelago of Guadeloupe (France). Vet Parasitol Reg Stud Reports 2024; 56:101132. [PMID: 39550188 DOI: 10.1016/j.vprsr.2024.101132] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2024] [Revised: 08/30/2024] [Accepted: 09/30/2024] [Indexed: 11/18/2024]
Abstract
Vector-borne diseases represent a major health challenge, both because of the complexity of their control, their common zoonotic nature, or the pathology they can cause in the individual. In tropical areas, surveillance of these diseases is even more important, since the activity of vectors is usually continuous throughout the year. To develop effective prophylaxis and surveillance programs, it is important to know the identity and prevalence of these pathogens as well as their distribution in a given territory. In Guadeloupe, a French archipelago located in the Lesser Antilles of the Caribbean, no information exists about vector-borne diseases in companion animals. With this aim, blood samples were obtained from 46 owned dogs with outdoor access from five different veterinary clinics located in the two mainland islands, and the presence of DNA of the main canine vector-borne pathogens (CVBP) was investigated through diverse PCR protocols. At least one pathogen was detected in 30.4 % of the dogs. The most frequently detected CVBP was Coxiella burnetii (17.4 %), followed by Dirofilaria immitis (8.7 %), and Candidatus Mycoplasma haematoparvum, Hepatozoon canis and Rickettsia spp. (2.2 % in all cases). One dog was coinfected with Candidatus M. haematoparvum and D. immitis. All samples were negative for Anaplasma spp., Ehrlichia spp., Bartonella spp., Borrelia burgdorferi sensu lato, piroplasmids, and Leishmania spp. No significant differences in pathogen occurrence were observed between the two main islands or according to the dog's sex and age groups. This study contributes to filling a relevant gap in the knowledge of vector-borne diseases in the Caribbean.

Detection and characterization of hemotropic Mycoplasmas in Iberian wolves (Canis lupus signatus) of Cantabria, Spain. INFECTION, GENETICS AND EVOLUTION : JOURNAL OF MOLECULAR EPIDEMIOLOGY AND EVOLUTIONARY GENETICS IN INFECTIOUS DISEASES 2024; 124:105659. [PMID: 39173940 DOI: 10.1016/j.meegid.2024.105659] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/06/2024] [Revised: 08/13/2024] [Accepted: 08/19/2024] [Indexed: 08/24/2024]
Abstract
Hemoplasmas (hemotropic mycoplasmas) are uncultivable wall-less bacteria able to infect mammalian erythrocytes. Hemoplasmas can cause anemia, especially in immunocompromised hosts, predisposing to secondary infections and even leading to death. Between 2017 and 2023, spleen samples of 131 wild Iberian wolves (Canis lupus signatus) of Cantabria (Spain) were screened for Mycoplasma spp. using a real-time PCR able to amplify a 360 bp fragment of the 16S rRNA gene and confirmed by direct Sanger sequencing. Additional conventional PCRs were performed to screen for coinfections by different Mycoplasma species and to discriminate between Mycoplasma haemocanis/haemofelis (Mhc/Mhf). Overall, 24/131 (18.3%) animals were PCR-positive. Biological and environmental factors potentially promoting hemoplasma infection in this species were analyzed. Two different hemoplasma species were detected: Mhc/Mhf (18/131; 13.7%) and Candidatus Mycoplasma haematoparvum (CMhp) (3/131; 2.3%), each with one nucleotide sequence type (ntST); three other sequences were not classified. No Mhc/Mhf and CMhp coinfection were observed. The 12 Mhc/Mhf suitable for ribonuclease P RNA sequencing were confirmed as Mhc. Mhc ntST was 100% identical to a Mhc sequence previously obtained in domestic dogs (Canis lupus familiaris), and in wild Iberian wolves of northwestern Spain (Asturias and Galicia) at a similar prevalence to the one found herein, suggesting a high Mhc genetic homogeneity in this wild population. CMhp ntST was 100% identical to CMhp sequences from domestic dogs. To our knowledge, this is the first description of CMhp in the Iberian wolf. The high genetic similarity observed in Mhc and CMhp sequences, as well as their high similarity with domestic dog sequences, suggest its recent introduction, a high level of intraspecific transmission within the wild wolf population, and likely, interspecific transmission between wolves and domestic dogs.

Abstract
Hemotropic Mycoplasma species are vector-borne bacteria that attach and grow on the surface of erythrocytes in various mammals, yet reports of canine hemoplasmosis in Iran are scarce. The aim of this study was molecular detection and identification of hemoplasmas in the blood of dogs (n = 370) from five provinces of Iran and ectoparasites infesting them including Ctenocephalides canis and Pulex irritans fleas, Rhipicephalus sanguineus sensu lato ticks, Heterodoxus spiniger lice and Hippobosca longipennis keds. Hemotropic Mycoplasma spp. pathogens were detected using genus-specific conventional PCRs, and subsequently identified using species-specific PCRs for Mycoplasma haemocanis (Mhc), and Candidatus Mycoplasma haematoparvum (CMhp). Sanger sequencing was then performed to confirm the species. Correlation of infection and risk factors (geographical area, keeping condition, body condition, sex, age, ectoparasite infestation) were analyzed. In total, 210 dogs (56.7%) were tested PCR-positive for hemotropic Mycoplasma spp. Species-specific PCR and sequencing revealed infection with Mhc in 17.8%, with CMhp in 7.02% and co-infection in 31.9% of dogs. Flea infestation, poor body condition, and being older than 3-years-old correlated with hemoplasmosis. In ectoparasites, DNA of hemoplasmas were detected only in fleas i.e. Mhc in P. irritans, CMhp in P. irritans and C. canis, and co-infection in C. canis. To our knowledge, this is the first large-scale molecular epidemiology study of canine hemoplasmosis in Iran. Considering the high prevalence of canine hemoplasmosis all over the country including potentially zoonotic CMhp, effective ectoparasite control strategies, regular examination of dogs, successful chemoprophylaxis and public awareness strategies are advocated.

Abstract
BACKGROUND Ixodid ticks, particularly Rhipicephalus sanguineus s.l., are important vectors of various disease-causing agents in dogs and humans in Cuba. However, our understading of interactions among tick-borne pathogens (TBPs) in infected dogs or the vector R. sanguineus s.l. remains limited. This study integrates microfluidic-based high-throughput real-time PCR data, Yule's Q statistic, and network analysis to elucidate pathogen-pathogen interactions in dogs and ticks in tropical western Cuba. METHODS A cross-sectional study involving 46 client-owned dogs was conducted. Blood samples were collected from these dogs, and ticks infesting the same dogs were morphologically and molecularly identified. Nucleic acids were extracted from both canine blood and tick samples. Microfluidic-based high-throughput real-time PCR was employed to detect 25 bacterial species, 10 parasite species, 6 bacterial genera, and 4 parasite taxa, as well as to confirm the identity of the collected ticks. Validation was performed through end-point PCR assays and DNA sequencing analysis. Yule's Q statistic and network analysis were used to analyse the associations between different TBP species based on binary presence-absence data. RESULTS The study revealed a high prevalence of TBPs in both dogs and R. sanguineus s.l., the only tick species found on the dogs. Hepatozoon canis and Ehrlichia canis were among the most common pathogens detected. Co-infections were observed, notably between E. canis and H. canis. Significant correlations were found between the presence of Anaplasma platys and H. canis in both dogs and ticks. A complex co-occurrence network among haemoparasite species was identified, highlighting potential facilitative and inhibitory roles. Notably, H. canis was found as a highly interconnected node, exhibiting significant positive associations with various taxa, including A. platys, and E. canis, suggesting facilitative interactions among these pathogens. Phylogenetic analysis showed genetic diversity in the detected TBPs. CONCLUSIONS Overall, this research enhances our understanding of TBPs in Cuba, providing insights into their prevalence, associations, and genetic diversity, with implications for disease surveillance and management.

Occurrence of Mycoplasma parvum in German Pigs of Different Age Groups Using a Novel Quantitative Real-Time PCR Assay. Pathogens 2022; 11:pathogens11111374. [PMID: 36422625 PMCID: PMC9692515 DOI: 10.3390/pathogens11111374] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Revised: 11/11/2022] [Accepted: 11/14/2022] [Indexed: 11/19/2022] Open
Abstract
Mycoplasma (M.) parvum is a hemotrophic bacterium circulating in the blood of pigs but is not considered a primary pathogen. Only a handful of studies dealing with this agent have been published since its first description in 1951, and many issues, including epidemiology and the impact of subclinical infections, are yet to be elucidated. This study aimed to establish a M. parvum specific real-time PCR for its detection and quantification in porcine blood and the application of this assay to obtain insights into the occurrence of M. parvum in German pigs. Furthermore, 16S rDNA amplicons of M. parvum positive blood samples were phylogenetically analyzed using MEGA 11 software. The established qPCR targeting the M. parvum glyceraldehyde-3-phosphate dehydrogenase encoding gene (gap) showed a lower detection limit of 10 gene copies per reaction and no cross-reactivity within the specificity test. A total of 36.0% (n = 72) of the sampled fattening pigs, 25.0% (n = 15) of the sows, and 4.37% (n = 8) of the boars tested M. parvum positive. The dendrogram showed the typical allocation of the M. parvum isolates into the "haemominutum group" subgroup within the hemotrophic Mycoplasma species. Both the novel established qPCR and the obtained epidemiological data can serve as an important basis for future studies dealing with M. parvum.

Molecular detection of haemophilic pathogens reveals evidence of Candidatus Mycoplasma haemobos in dogs and parasitic ticks in central China. BMC Vet Res 2022; 18:254. [PMID: 35778709 PMCID: PMC9248110 DOI: 10.1186/s12917-022-03361-x] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2022] [Accepted: 06/22/2022] [Indexed: 11/21/2022] Open
Abstract
Background In addition to Mycoplasma haemocanis and Candidatus Mycoplasma haematoparvum, a few hemoplasma species that mainly infect other livestock have been detected in dogs. ‘Candidatus Mycoplasma haemobos’ (Ca. M. haemobos) has been found in a variety of animals in China. The present study was aimed to investigate the occurrence of ‘Ca. M. haemobos’ infections in dogs and ticks collected from the Henan province, China. Results Overall, 55 dog blood samples and 378 ticks on skins were collected from anemic and healthy dogs, and these samples were subjected to PCR, sequence analysis, and identification. The results showed that Haemaphysalis longicornis (266) and Rhipicephalus (Boophilus) microplus (112) were the only two parasitic ticks on dogs. Molecular detection revealed that 163 M. haemocanis, 88 ‘Ca. M. haemobos’ and 32 Anaplasma platys positive amplicons could be amplified from dogs, H. longicornis and R. (B.) microplus. In addition, co-infections (M. haemocanis + A. platys and ‘Ca. M. haemobos’+ A. platys) could be also detected. Conclusions To the best of our knowledge, this is the first molecular evidence of ‘Ca. M. haemobos’ natural infection in dogs and tick species identified as H. longicornis and R. (B.) microplus from China.
