The occurrence of common respiratory parasites of domestic cats (the metastrongyloid "cat lungworm" Aelurostrongylus abstrusus and the trichuroid Capillaria aerophila) and of neglected respiratory nematodes of felids (Troglostrongylus brevior, Angiostrongylus chabaudi and Oslerus rostratus) was here evaluated in two and three geographical sites of Northern and Central Italy, respectively. In 2014-2015, individual fecal samples of 868 domestic cats were examined microscopically and genetically, and epidemiological data related to parasitic infections were evaluated as possible risk factors by binary logistic regression models. The most common parasite was A. abstrusus in both mono- and poli-specific infections, followed by T. brevior and C. aerophila, while cats scored negative for other parasites. Cats positive for A. abstrusus (1.9-17 % infection rate) and C. aerophila (0.9-4.8 % infection rate) were found in all examined sites, while cats scored positive for T. brevior (1-14.3 % infection rate) in four sites. Also, T. brevior was here found for the first time in a domestic cat from a mountainous area of Northern Italy. The occurrence of lungworms was statistically related to the presence of respiratory signs and more significant in cats with mixed infection by other lungworms and/or intestinal parasites. Cats living in site C of Central Italy resulted statistically more at risk of infection for lungworms than cats living in the other study sites, while animals ageing less than 1 year were at more risk for troglostrongylosis. Finally, the presence of lungworms was more significant in cats with mixed infection by other lungworms and/or intestinal parasites. These results are discussed under epidemiological and clinical points of views.
本文评估了意大利北部和中部两个及三个地理区域内家猫常见呼吸道寄生虫（圆线虫类“猫肺线虫”——隐匿管状线虫和毛首线虫类嗜气毛细线虫）以及猫科动物被忽视的呼吸道线虫（短管圆线虫、沙氏血管圆线虫和吻状奥氏线虫）的感染情况。2014年至2015年期间，对868份家猫个体粪便样本进行了显微镜检查和基因检测，并通过二元逻辑回归模型评估了与寄生虫感染相关的流行病学数据，将其作为可能的风险因素。在单种和多种寄生虫感染中，最常见的寄生虫是隐匿管状线虫，其次是短管圆线虫和嗜气毛细线虫，而其他寄生虫检测结果均为阴性。在所有检测地点均发现了隐匿管状线虫呈阳性的猫（感染率为1.9% - 17%）和嗜气毛细线虫呈阳性的猫（感染率为0.9% - 4.8%），在四个地点发现了短管圆线虫呈阳性的猫（感染率为1% - 14.3%）。此外，在意大利北部山区的一只家猫中首次发现了短管圆线虫。肺线虫的出现与呼吸道症状在统计学上相关，并且在同时感染其他肺线虫和/或肠道寄生虫的猫中更为显著。生活在意大利中部C地点的猫在统计学上比生活在其他研究地点的猫感染肺线虫的风险更高，而年龄小于1岁的动物感染管圆线虫病的风险更高。最后，在同时感染其他肺线虫和/或肠道寄生虫的猫中，肺线虫的存在更为显著。本文从流行病学和临床角度对这些结果进行了讨论。
