Endoparasitic infections are common in stray cats. Many of these parasites are responsible for zoonoses, and stray cats can be a source of environmental contamination. The prevalence of parasites in 139 stray colony cats in the city of Milan, northern Italy, was investigated by faecal examination. The overall prevalence of endoparasites was 50.4%, with 11 different parasites found. Parasites with zoonotic potential were detected in 49.6% of cats. Concurrent infections with two or more zoonotic parasites were recorded in 14.3% of cats. Among the parasites found, the most common was Toxocara cati (33.1%; P <0.0001). The other species found by coproscopic examination were: Ancylostoma tubaeformae (7.2%), Isospora species (4.3%), Trichuris vulpis (2.9%), Dipylidium caninum (2.9%), Aelurostrongylus abstrusus (2.9%), Eucoleus aerophilus (syn Capillaria aerophila) (1.4%), Spirometra species (1.4%), Taenia pisiformis (0.7%) and Hymenolepis nana (0.7%). Coproantigen specific for Giardia duodenalis was detected in 2.9% of the samples. Pseudoparasites (eggs of mites) were found in 4.3% of the samples. No sample contained Toxoplasma gondii oocysts, despite the fact that 70 cats tested positive for T gondii-specific IgG antibodies, and none of the diarrhoetic samples tested positive for Cryptosporidium species oocysts. Variables linked to infection were body condition score (BCS), the presence of diarrhoea and infection with G duodenalis. Cats infected with G duodenalis were more likely to have a low BCS (odds ratio (OR) = 11.5, P = 0.02) and diarrhoea (OR = 30.7, P = 0.0007). The results of the present study confirm that endoparasitic infections, most of which have zoonotic potential, are distributed in stray colony cats of Milan.
体内寄生虫感染在流浪猫中很常见。这些寄生虫中的许多会引发人畜共患病，流浪猫可能成为环境污染源。通过粪便检查对意大利北部米兰市139只流浪猫群落中的寄生虫感染率进行了调查。体内寄生虫的总体感染率为50.4%，共发现了11种不同的寄生虫。49.6%的猫检测出具有人畜共患潜力的寄生虫。14.3%的猫记录到感染了两种或更多种人畜共患寄生虫。在所发现的寄生虫中，最常见的是猫弓首蛔虫（33.1%；P<0.0001）。通过粪便检查发现的其他种类有：管状钩口线虫（7.2%）、等孢球虫属（4.3%）、狐毛首线虫（2.9%）、犬复孔绦虫（2.9%）、猫圆线虫（2.9%）、嗜气欧氏线虫（同嗜气毛细线虫）（1.4%）、裂头绦虫属（1.4%）、豆状带绦虫（0.7%）和微小膜壳绦虫（0.7%）。2.9%的样本检测出十二指肠贾第虫的粪抗原。4.3%的样本中发现了假寄生虫（螨卵）。尽管70只猫的弓形虫特异性IgG抗体检测呈阳性，但没有样本含有刚地弓形虫卵囊，腹泻样本中也没有隐孢子虫属卵囊检测呈阳性。与感染相关的变量有身体状况评分（BCS）、腹泻情况以及十二指肠贾第虫感染。感染十二指肠贾第虫的猫更有可能身体状况评分较低（优势比（OR）=11.5，P=0.02）且出现腹泻（OR=30.7，P=0.0007）。本研究结果证实，体内寄生虫感染（其中大多数具有人畜共患潜力）在米兰的流浪猫群落中广泛存在。
