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.
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.
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.
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.
本研究旨在评估罗马尼亚南部犬巴贝斯虫病和肝孢子虫病的流行情况，并评估该地区不同地区之间的流行率是否存在差异。
通过 PCR 从罗马尼亚南部的 300 只狗的血液样本中筛选出梨形虫。对阳性样本进一步检测是否存在巴贝斯虫属和犬肝孢子虫。采用 Pearson 卡方检验（Yates 校正）来确定感染人群之间是否存在统计学差异。
54%（163/300）的狗感染了肝孢子虫属或梨形虫。48%（143/300）感染了犬肝孢子虫，9.6%（29/300）对犬巴贝斯虫呈阳性。3%（9/300）的狗同时感染了巴贝斯虫属和犬肝孢子虫。罗马尼亚西南部的犬肝孢子虫感染率明显高于其他三个地区（p<0.05），而该国东南部的巴贝斯虫属感染率明显高于其西南部（p<0.05）。
在所调查的流浪犬群体中，犬肝孢子虫的感染率很高，其中西南部的感染率最高。在罗马尼亚东南部，犬巴贝斯虫属感染的威胁最大，而在西南部犬肝孢子虫感染率较高的地区，感染了犬巴贝斯虫 vogeli。这些感染应引起罗马尼亚兽医和狗主人的高度关注。
