Mycoplasma haemocanis (Mhc) and “Candidatus Mycoplasma haematoparvum” (CMhp) are the main haemoplasma species known to infect dogs. The aim of this study was to determine the prevalence of haemoplasma species infections in hunting dogs from southern Italy and assess related risk factors. 1,433 hunting dogs living in Campania region were tested by qPCR assay. The prevalence was 19.9 %; 13.1 % for Mhc and 11.4 % for CMhp; 4.6 % showed a coinfection with both haemoplasma species. Statistical analysis revealed living in Salerno province (Mhc: OR 3.72; CMhp: OR 2.74), hound (Mhc: OR 5.26; CMhp: OR 8.46) and mixed breed (Mhc: OR 3.38; CMhp: OR 2.80), rural environment (Mhc: OR 12.58; CMhp: OR 10.38), wild mammal hunting (Mhc: OR 8.73; CMhp: OR 8.32), cohabitation with other animals (Mhc: OR 2.82; CMhp: OR 2.78) and large pack size (Mhc: OR 2.96; CMhp: OR 1.61) as risk factors for haemoplasmas. Male gender (OR 1.44) and tick infestation history (OR 1.40) represented risk factors only for Mhc, while adult age (2−7 years - OR 2.01; > 7 years - OR 1.84) and large body size (OR 1.48) were associated only to CMhp. Mhc infection was significantly associated to Babesia vogeli (p < 0.05) and Hepatozoon canis (p < 0.001), while CMhp with H. canis (p < 0.001). This study adds information on haemoplasma species distribution in hunting dogs in southern Italy. Outdoor lifestyle and contact with wild fauna, through greater exposure to tick infestation, or possibly wounds acquired during hunting or fighting, could be factors contributing to haemoplasma infections.

支原体haemocanis（MHC）和“暂定支原体haematoparvum” （招商局亚太）已知感染犬主haemoplasma品种。这项研究的目的是确定意大利南部狩猎犬中血友病物种感染的流行程度，并评估相关的危险因素。通过qPCR测定法测试了生活在坎帕尼亚地区的1,433只猎犬。患病率为19.9％；Mhc为13.1％，CMhp为11.4％; 4.6％的人同时出现两种血友病。统计分析表明，他们生活在萨勒诺省（Mhc：OR 3.72; CMhp：OR 2.74），猎犬（Mhc：OR 5.26; CMhp：OR 8.46）和混合品种（MhcMhc：OR 3.38；CMhp：OR 2.80），乡村环境（Mhc：OR 12.58；CMhp：OR 10.38），狩猎野生哺乳动物（Mhc：OR 8.73；CMhp：OR 8.32），与其他动物同居（Mhc：OR 2.82；CMhp：OR 2.78）并以大包装（Mhc：2.96；CMhp：OR 1.61）作为血肿的危险因素。男性（OR 1.44）和tick虫病史（OR 1.40）仅代表Mhc的危险因素，而成年年龄（2-7岁-OR 2.01；> 7岁-OR 1.84）和大体重（OR 1.48）相关仅对CMhp而言。h感染与巴贝斯虫（p <0.05）和犬肝炎（p <0.001）显着相关，而CMhp与犬肝炎（p <0.001）显着相关。这项研究增加了意大利南部狩猎犬中血肿种类分布的信息。户外生活方式和与野生动植物的接触，可能是由于更多地接触tick虫，或在狩猎或战斗中可能会受伤，可能是导致血友病感染的因素。
