Abstract：
Understanding the epidemiology of canine parasitic infections, gastrointestinal helminthic infections in particular, is crucial for designing an efficient control programs targeted at minimizing the risks of zoonotic transmission. A total of 470 dogs attending veterinary clinics in Northeastern Nigeria were screened for gastrointestinal helminths using standard parasitological techniques. Epidemiological risk factors associated with the canine parasitic infections were assessed using multivariable logistic regression analysis. In total, 77.9% (366/470) of dogs had harboured one or more species of the gastrointestinal helminths: Ancylostoma caninum (40.2%), Toxocara canis (35.1%) Trichuris vulpis (26.6%), Spirocerca lupi (5.7%), Taenia/Echinococcus (12.3%), Dipylidium caninum (10.9%) and Diphyllobothriid ova (2.8%). Female dogs (OR=2.1; p=0.02), local breeds (OR=2.3; p<0.01), younger dogs (OR=3.2; p<0.001), dogs adopted as security guards (OR=1.8; p<0.01) and poor body condition score (OR=3.1; p<0.001) were strongly associated with A. caninum infection. For T. canis and T. vulpis, younger dogs (OR=2.5; p=0.02 and OR=2.3; p<0.01) and poor body condition score (OR=4.2; p<0.001 and OR=2.2; p<0.01) were the strong predictors for infection, whereas female dogs (OR=2.8; p=0.02), younger dogs (OR=4.1; p<0.001) and poor body condition score (OR=4.0; p<0.001) were strongly associated with D. caninum infection in dogs. The results revealed high prevalence of gastrointestinal helminths-some of which have zoonotic potential-among dogs underlying huge public health risk.
摘要：
了解犬寄生虫感染的流行病学，尤其是胃肠道蠕虫感染，对于设计旨在最大程度地减少人畜共患传播风险的有效控制程序至关重要。使用标准寄生虫学技术对尼日利亚东北部兽医诊所的470只狗进行了胃肠道蠕虫筛查。使用多变量logistic回归分析评估与犬寄生虫感染相关的流行病学危险因素。总的来说,77.9％（366/470）的狗有一种或多种胃肠道蠕虫：Ancylostomacaninum（40.2％），犬弓形虫(35.1%)鞭毛虫(26.6%),Spirocercalupi（5.7％），棘球蚴/棘球蚴(12.3%),犬二吡啶（10.9％）和二叶虫（2.8％）。雌性犬（OR=2.1；p=0.02），当地品种(OR=2.3；p<0.01)，较年轻的狗（OR=3.2；p<0.001），作为保安的狗(OR=1.8;p<0.01)和不良身体状况评分(OR=3.1;p<0.001)与犬A.对于T.canis和T.vulpis，较年轻的狗（OR=2.5;p=0.02和OR=2.3;p<0.01）和不良身体状况评分（OR=4.2;p<0.001和OR=2.2;p<0.01）是感染的有力预测因子，而雌性狗（OR=2.8；p=0.02），年轻犬(OR=4.1;p<0.001)和不良身体状况评分(OR=4.0;p<0.001)与犬中D.caninum感染密切相关。结果表明，在狗中，胃肠道蠕虫的患病率很高，其中一些具有人畜共患潜力，这对公共健康构成了巨大的风险。
