Abstract:
Purpose: The aim of this study was to evaluate the prevalence and distribution of canine babesiosis and hepatozoonosis in the south of Romania as well as to assess if there are differences in the prevalence between regions in that area.
Methods: Blood samples from 300 dogs from the south of Romania were screened for the presence of piroplasmids by PCR. Positive samples were further tested for the presence of Babesia spp. and Hepatozoon canis. Pearson's chi-square with Yates correction was used to determine if there is statistical difference between infected populations.
Results: Fifty-four percent (163/300) of the dogs were positive for Hepatozoon spp. or piroplasmids. Forty-eight percent (143/300) were infected with H. canis and 9.6% (29/300) were positive to B. canis. Three percent (9/300) of the dogs were co-infected with Babesia spp. and H. canis. The prevalence of H. canis in the south-west of Romania was significantly higher (p < 0.05) than that of three other regions while the prevalence of Babesia spp. infection in the south-east of the country was significantly higher (p < 0.05) compared to its south-west.
Conclusions: A high rate of H. canis infection was found in the stray dog population surveyed with the highest infection rate detected in south-western Romania. Babesia canis was found to pose the highest threat in south-eastern Romania, whereas B. vogeli infection was focused in the same region of high H. canis infection in south-western Romania. These infections should be of important concern to veterinarians and dog owners in Romania.
