Abstract
Feline chaphamaparvovirus (FeChPV) is a recently discovered parvovirus in cats that is linked to respiratory and enteric diseases. Notably, FeChPV is also detected in healthy cats, warranting further investigation into its clinical significance. This study aimed to assess the presence of FeChPV in cats across Thailand while also exploring its genetic characteristics through phylogenetic, recombination, and selective pressure analyses. Molecular investigations were performed on oropharyngeal swabs from both healthy (n = 165) and diseased (n = 167) cats. The findings revealed an FeChPV detection rate of 10.2 % (34/332), with the virus detected in both healthy (9.1 %, 15/165) and diseased cats (11.4 %, 19/167). However, no significant association was observed between these conditions and the presence of FeChPV (p = 0.5879). Among the FeChPV-positive cases, 61.8 % (21/34) exhibited concurrent detection with common feline viruses. Apart from oropharyngeal swab samples, FeChPV was also detected in additional clinical samples, including nasal swabs, auricular swabs, rectal swabs, and urine samples. Phylogenetic analysis of the complete coding sequence indicated that most FeChPV strains in this study clustered into a single clade, except for BKK052 and CB050. Two recombinant strains (C14 and HF2) from China were found, in which FeChPV CB050 Thai strain served as putative minor and major parents, respectively. The NS1 and VP1 codon sequences underwent negative selective pressure, with multiple positive selection sites observed. Although a specific disease associated with FeChPV infection could not be concluded, underlying health conditions may increase susceptibility to FeChPV infection. Further research is essential to comprehensively understand the role of this virus in feline health.
期刊介绍:
(aka Journal of Molecular Epidemiology and Evolutionary Genetics of Infectious Diseases -- MEEGID)
Infectious diseases constitute one of the main challenges to medical science in the coming century. The impressive development of molecular megatechnologies and of bioinformatics have greatly increased our knowledge of the evolution, transmission and pathogenicity of infectious diseases. Research has shown that host susceptibility to many infectious diseases has a genetic basis. Furthermore, much is now known on the molecular epidemiology, evolution and virulence of pathogenic agents, as well as their resistance to drugs, vaccines, and antibiotics. Equally, research on the genetics of disease vectors has greatly improved our understanding of their systematics, has increased our capacity to identify target populations for control or intervention, and has provided detailed information on the mechanisms of insecticide resistance.
However, the genetics and evolutionary biology of hosts, pathogens and vectors have tended to develop as three separate fields of research. This artificial compartmentalisation is of concern due to our growing appreciation of the strong co-evolutionary interactions among hosts, pathogens and vectors.
Infection, Genetics and Evolution and its companion congress [MEEGID](http://www.meegidconference.com/) (for Molecular Epidemiology and Evolutionary Genetics of Infectious Diseases) are the main forum acting for the cross-fertilization between evolutionary science and biomedical research on infectious diseases.
Infection, Genetics and Evolution is the only journal that welcomes articles dealing with the genetics and evolutionary biology of hosts, pathogens and vectors, and coevolution processes among them in relation to infection and disease manifestation. All infectious models enter the scope of the journal, including pathogens of humans, animals and plants, either parasites, fungi, bacteria, viruses or prions. The journal welcomes articles dealing with genetics, population genetics, genomics, postgenomics, gene expression, evolutionary biology, population dynamics, mathematical modeling and bioinformatics. We also provide many author benefits, such as free PDFs, a liberal copyright policy, special discounts on Elsevier publications and much more.
