Özet
Hepatozoon spp. are an apicomplexan protozoan parasites that infect vertebrates including mammals, marsupials, birds, reptiles, and amphibians. Among Hepatozoon species, H. canis and H. felis are causative agents of hepatozoonosis in dogs and cats, respectively and have veterinary importance. This study aimed to determine the prevalence of Hepatozoon spp. in stray cats living in İzmir and investigate genetic diversity among positive samples. To achieve this aim, the prevalence of Hepatozoon spp. 18S rRNA gene was screened by PCR in DNA samples extracted from blood samples of stray cats (n = 1012). Then, Hepatozoon-positive samples were sequenced and the generated data were used for species identification, phylogenetic and haplotype analyses. According to the results, among the samples screened, 2.37 % (24/1012) of them were found to be Hepatozoon-positive, and of these positive samples, 18 (18/24; 75 %) were successfully sequenced. BLAST and phylogenetic analyses revealed that all of these samples were H. felis. Also, phylogenetic analysis showed that H. felis samples were genotype I. Within H. felis samples isolated from cats living in different countries/regions, 9 haplotypes were detected and among these haplotypes, H-1 was found to be prevalent (n = 20 H. felis isolates). In conclusion, this study showed that the prevalence of Hepatozoon spp. was low in stray cats analyzed. Also, H. felis genotype I was predominant in comparison to other Hepatozoon species.
