Seroprevalence and risk factors associated with visceral leishmaniasis in dogs in Jaciara, State of Mato Grosso

Introduction Visceral leishmaniasis is a neglected disease. Jaciara, State of Mato Grosso has the most cases. This study aimed to determine the risk factors and seroprevalence of canine visceral leishmaniasis in urban and rural areas. Methods This cross-sectional study of domestic dogs used enzyme-linked immunosorbent assay and indirect immunofluorescence test. Results The prevalence was 54.7% among 345 analyzed samples. Short coat, age of 1-6 years, and living less than 100m from vegetation posed the highest infection risks. Conclusions Certain dog behaviors and characteristics, and their correlation with environmental conditions, were relevant in the high prevalence of canine leishmaniasis in Jaciara.一、引言 内脏利什曼病（Visceral leishmaniasis）是一类被忽视的传染病。马托格罗索州（Mato Grosso）的雅西阿拉（Jaciara）是该疾病病例最多的地区。本研究旨在明确城乡地区犬内脏利什曼病（canine visceral leishmaniasis）的血清阳性率及其相关危险因素。 二、研究方法 本项针对家犬的横断面研究（cross-sectional study）采用了酶联免疫吸附试验（enzyme-linked immunosorbent assay）与间接免疫荧光试验（indirect immunofluorescence test）开展检测。 三、研究结果 本次研究共分析345份样本，血清阳性率为54.7%。其中短毛犬、1至6岁龄犬只以及居住距离植被带不足100米的犬只感染风险最高。 四、结论 犬只的部分行为与特征，及其与环境条件的相关性，与雅西阿拉地区犬利什曼病的高流行率密切相关。
