Trichuris spp. infections can cause typhlitis or typhlocolitis in many species, but there are no published studies about its pathology in cats. Trichuris sp. infection in cats appears to be rare in most parts of the world but is frequent in some tropical and subtropical regions. The purpose of this study was to describe intestinal lesions associated with natural Trichuris sp. infections in cats of St. Kitts, West Indies. Comprehensive autopsies, histopathological assessment of small and large intestine, and total worm counts were performed in a cross-sectional study of 30 consecutive feline mortalities. Trichuris were found in 17 of 30 (57%; 95% confidence interval, 39%-74%) of the study cats with a median worm count of 11 (range, 1-170), indicating most cats had a low-intensity infection. Trichuris infection was associated with typhlitis but not consistency of feces or body condition score. In most cats examined, the typhlitis was categorized as mild (10/15, 67%) and, less frequently, moderate (2/15, 13%) or marked (3/15, 20%). The inflammatory infiltrate varied from predominantly eosinophilic (5/15, 33%) to neutrophilic (4/15, 27%), a mixture of eosinophilic and neutrophilic (2/15, 13%), a mixture of neutrophilic and lymphoplasmacytic (1/15, 7%), or a mixture of eosinophilic, neutrophilic, and lymphoplasmacytic (3/15, 20%). In some cats, surface erosions and catarrhal exudate were adjacent to adult worms. These findings are similar to those reported with low-intensity Trichuris infections in other species.

与自然Trichuris sp。相关的伤寒。猫感染。

旋毛虫属 感染可在许多物种中引起肺炎或肺炎,但目前尚无有关猫病理性的公开研究。旋毛虫 在世界上大多数地区,猫的感染似乎很少见,但在某些热带和亚热带地区却很常见。这项研究的目的是描述与天然Trichuris sp。相关的肠病变。西印度群岛圣基茨的猫感染。在连续30次猫死亡的横断面研究中,进行了全面的尸检,小肠和大肠的组织病理学评估以及蠕虫总数。在30只研究猫中,有17只(占57%; 95%置信区间,39%-74%)发现蠕虫,蠕虫中位数为11(范围1-170),表明大多数猫感染低强度。滴虫感染与伤寒相关,但粪便或身体状况评分不一致。在大多数接受检查的猫中,伤寒分为轻度(10/15,67%),较不常见的是中度(2/15,13%)或明显(3/15,20%)。炎性浸润从嗜酸性粒细胞(5/15,33%)到嗜中性粒细胞(4/15,27%),嗜酸性粒细胞和嗜中性粒细胞的混合物(2/15,13%),嗜中性粒细胞和淋巴浆细胞的混合物(1 / 15、7%)或嗜酸性,嗜中性和淋巴浆溶性混合物(3 / 15,20%)。在某些猫中,表面侵蚀和卡他性渗出液与成年蠕虫相邻。这些发现与其他物种的低强度滴虫感染报告的结果相似。较不频繁,中度(2/15,13%)或显着(3/15,20%)。炎性浸润从嗜酸性粒细胞(5/15,33%)到嗜中性粒细胞(4/15,27%),嗜酸性粒细胞和嗜中性粒细胞的混合物(2/15,13%),嗜中性粒细胞和淋巴浆细胞的混合物(1 / 15、7%)或嗜酸性,嗜中性和淋巴浆溶性混合物(3 / 15,20%)。在某些猫中,表面侵蚀和卡他性渗出液与成年蠕虫相邻。这些发现与其他物种的低强度滴虫感染报告的结果相似。较不频繁,中度(2/15,13%)或明显(3/15,20%)炎性浸润从嗜酸性粒细胞(5/15,33%)到嗜中性粒细胞(4/15,27%),嗜酸性粒细胞和嗜中性粒细胞的混合物(2/15,13%),嗜中性粒细胞和淋巴浆细胞的混合物(1 / 15、7%)或嗜酸性,嗜中性和淋巴浆溶性混合物(3 / 15,20%)。在某些猫中,表面侵蚀和卡他性渗出液与成年蠕虫相邻。这些发现与其他物种的低强度滴虫感染报告的结果相似。或嗜酸性,嗜中性和淋巴浆细胞性的混合物(3 / 15,20%)。在某些猫中,表面侵蚀和卡他性渗出液与成年蠕虫相邻。这些发现与其他物种的低强度滴虫感染报告的结果相似。或嗜酸性,嗜中性和淋巴浆细胞性的混合物(3 / 15,20%)。在某些猫中,表面侵蚀和卡他性渗出液与成年蠕虫相邻。这些发现与其他物种的低强度滴虫感染报告的结果相似。
