Gastrointestinal and cardiopulmonary nematodes are frequently detected in dogs worldwide, posing a potential zoonotic risk. Some parasites, such as Capillaria aerophila and Capillaria boehmi, are often less considered being misdiagnosed with other trichurids. Here, we evaluated the occurrence of Capillaria spp. as well as of other endoparasites in hunting dogs from Basilicata region, Southern Italy. Individual faecal samples were collected from hunting dogs (n = 443) and examined by Mini-FLOTAC® flotation method. Additionally, 49 of the above samples were evaluated by the Baermann-Wetzel technique, and 90 sera samples were subjected to the Angio Detect™ test (IDEXX Laboratories Inc., Westbrook, Maine, USA). Out of 443 faecal samples, 251 (i.e., 56.6 %) scored positive for at least one parasite species, with hookworms being the most prevalent nematodes (i.e., 39.3 %), followed by C. aerophila (i.e., 20.5 %), Trichuris vulpis (i.e., 12.6 %) and Toxocara canis (i.e., 11.3 %). At the Baermann-Wetzel technique, 8.2 % (n = 4/49) of the faecal samples scored positive for Angiostrongylus vasorum, 4.1 % for Ancylostomatidae (n = 2/49) and 2.0 % for Strongyloides spp. (n = 1/49). A single serum sample scored positive for A. vasorum at the Angio Detect™ test. The results indicate that hunting dogs may harbour a high diversity of endoparasites, including those of zoonotic concern. Moreover, it is hypothesized that the occurrence of C. aerophila and C. boehmi may compromise the overall hunting performance due to the respiratory distress and impairment of scenting abilities. Therefore, control measures should be implemented to protect both dogs as well as humans living in close contact with them.
全球范围内，犬类中常检测到胃肠道和心肺线虫，存在潜在的人畜共患病风险。一些寄生虫，如嗜气毛细线虫和博氏毛细线虫，常被误诊为其他鞭虫，因而较少受到关注。在此，我们评估了意大利南部巴斯利卡塔地区猎犬体内毛细线虫属以及其他体内寄生虫的感染情况。从443只猎犬采集个体粪便样本，采用Mini-FLOTAC®漂浮法进行检测。此外，对上述49份样本采用贝尔曼-韦策尔技术进行评估，90份血清样本采用Angio Detect™检测（美国缅因州韦斯特布鲁克的IDEXX实验室公司）。在443份粪便样本中，251份（即56.6%）至少对一种寄生虫呈阳性反应，其中钩虫是最常见的线虫（即39.3%），其次是嗜气毛细线虫（即20.5%）、狐毛首线虫（即12.6%）和犬弓首蛔虫（即11.3%）。在贝尔曼-韦策尔技术检测中，49份粪便样本中有8.2%（n = 4/49）对血管圆线虫呈阳性反应，4.1%对钩口科线虫呈阳性反应（n = 2/49），2.0%对类圆线虫属呈阳性反应（n = 1/49）。在Angio Detect™检测中，一份血清样本对血管圆线虫呈阳性反应。结果表明，猎犬可能携带多种体内寄生虫，包括那些与人畜共患病相关的寄生虫。此外，据推测，嗜气毛细线虫和博氏毛细线虫的感染可能因呼吸窘迫和嗅觉能力受损而影响整体狩猎性能。因此，应实施防控措施以保护犬类以及与它们密切接触的人类。
