Abstract：
Many zoonotic parasitic diseases, including Toxocara cati, may be spread by stray cat populations. This study aimed to determine the prevalence of parasites by performing parasitological and histopathological examinations on stray cats in Shiraz, Iran. A total of 106 stray cats from different geographical areas of Shiraz, southern Iran, were examined for the presence of parasites. The overall prevalence was found to be 83.02% (88/106), and eight parasites were found. The parasites included three genera of cestodes [Joyeuxiella echinorhynoides (52.83%), Taenia taeniaeformis (21.70%), and Dipylidium caninum (1.89%)], three nematodes [Physaloptera praeputialis (23.59%), Toxocara cati (15.09%), and Rictularia sp. (1.89%)], one protozoa [Isospora spp. (6.60%)], and one arthropod [Ctenocephalides felis (5.66%)]. The prevalence did not significantly differ between males and females. It did appear, nevertheless, that the age of cats may be regarded as a risk factor for these parasitic infections. Histopathological examination revealed some parasite-induced lesions in the intestine and stomach, including hyperemia, hemorrhage, mucosal destruction and inflammation. The lung tissues showed some histopathological lesions such as hemorrhage, edema, emphysema and mild inflammation, and dormant larvae were found in one tongue sample. The results of the present study showed that parasitic infections and, more importantly, T. cati are relatively prevalent in stray cats, and the people living in this area are at serious risk of this zoonotic disease. The cats in this region need to be monitored, and specific preventive measures should be developed by public health officials.
摘要：
许多人畜共患寄生虫病，包括弓形虫，可能由流浪猫种群传播。这项研究旨在通过对设拉子的流浪猫进行寄生虫学和组织病理学检查来确定寄生虫的患病率，伊朗。共有106只来自设拉子不同地理区域的流浪猫，伊朗南部,检查寄生虫的存在。总体患病率为83.02％（88/106），发现了八种寄生虫。寄生虫包括三个属的cestodes[Joyeuxiellachinorhynoides（52.83％），牛带虫(21.70%),和犬碘（1.89%）]，三种线虫[Physalopterapraeputialis（23.59％），弓形虫(15.09%)，和Rictulariasp.（1.89%）]，一个原生动物[Isosporaspp.（6.60%）]，和一个节肢动物[Ctenocephalidesfelis（5.66％）]。男性和女性的患病率没有显着差异。它确实出现了，然而，猫的年龄可能被认为是这些寄生虫感染的危险因素。组织病理学检查显示肠道和胃中一些寄生虫引起的病变，包括充血,出血,粘膜破坏和炎症。肺组织显示一些组织病理学病变，如出血，水肿,肺气肿和轻度炎症,在一个舌头样本中发现了休眠的幼虫。本研究的结果表明,寄生虫感染,更重要的是,T.cati在流浪猫中相对普遍，生活在这个地区的人们面临着这种人畜共患疾病的严重风险。这个地区的猫需要被监控,公共卫生官员应制定具体的预防措施。
