Molecular detection of hemotropic mycoplasmas in cats and dogs from northern Vietnam: Evidence of interspecies transmission of Mycoplasma suis-like and Mycoplasma haemocanis-like in cats
Hemoplasmas are bacteria of the genus Mycoplasma that can attach to red blood cells and cause hemolytic anemia. The two main species that can infect dogs are Mycoplasma (M.) haemocanis and ‘Candidatus (Ca.) M. haematoparvum’; and three major species that can infect cats are M. haemofelis, ‘Ca. M. haemominutum’, and ‘Ca. M. turicensis’. However, there is a lack of research data regarding hemoplasma species infecting dogs and cats in Vietnam. Therefore, we aimed to investigate the molecular presence of hemotropic Mycoplasma in dogs and cats in northern Vietnam. We collected blood samples from dogs and cats and used PCR to precisely target the 16S rRNA gene of hemoplasma species in the blood samples. The results indicated that 1.2 % (95 % CI: 0.5 %–2.7 %; 6/489) of all samples, 1.4 % of cat samples (95 % CI: 0.4 %–3.5 %; 4/288) and 1 % of dog samples (95 % CI: 0.1 %–3.5 %; 2/201) were infected with hemoplasmas. Phylogenetic analysis showed the presence of two different species of hemoplasma, namely M. haemocanis-like and M. suis-likeg. Additional genetic characterization based on the 23S rRNA and RNase P RNA (rnpB) genes indicated that M. haemocanis-like isolates could be M. haemocanis, rather than M. haemofelis. Moreover, we detected M. haemocanis-like and M. suis-like in the blood samples collected from cats, indicating the possibility of interspecies transmission. Although previous studies have detected hemoplasma species in Vietnam, to the best of our knowledge, this study is the first to report the presence of M. haemocanis-like and M. suis-like in cats and M. haemocanis-like in dogs from Vietnam.
期刊介绍:
Research in Veterinary Science is an International multi-disciplinary journal publishing original articles, reviews and short communications of a high scientific and ethical standard in all aspects of veterinary and biomedical research.
The primary aim of the journal is to inform veterinary and biomedical scientists of significant advances in veterinary and related research through prompt publication and dissemination. Secondly, the journal aims to provide a general multi-disciplinary forum for discussion and debate of news and issues concerning veterinary science. Thirdly, to promote the dissemination of knowledge to a broader range of professions, globally.
High quality papers on all species of animals are considered, particularly those considered to be of high scientific importance and originality, and with interdisciplinary interest. The journal encourages papers providing results that have clear implications for understanding disease pathogenesis and for the development of control measures or treatments, as well as those dealing with a comparative biomedical approach, which represents a substantial improvement to animal and human health.
Studies without a robust scientific hypothesis or that are preliminary, or of weak originality, as well as negative results, are not appropriate for the journal. Furthermore, observational approaches, case studies or field reports lacking an advancement in general knowledge do not fall within the scope of the journal.
