摘　　要：为初步调查山东省莘县羊弓形虫病流行情况及潜在风险因素,2023年3月一2024年3月从莘县49个羊场户采集羊血清样品1240份,采用间接血凝试验(IHA)检测弓形虫抗体,并进一步分析影响该地区羊弓形虫病流行的相关风险因素。结果显示:莘县17个羊场户的103份血清样品为弓形虫抗体阳性,场群阳性率和个体阳性率分别为34.69%(17/49)和8.31%(103/1240),其中乡镇D场群阳性率(71.43%,5/7)和个体阳性率(17.11%,32/187)最高。进一步分析发现,不同年龄阶段、养殖模式和季节的羊群弓形虫抗体阳性率差异显著(P<0.05),且养殖场内是否养犬猫和卫生管理情况显著影响羊弓形虫感染率(P<0.05),但不同性别羊群弓形虫抗体阳性率差异不显著(P>0.05)。结果表明:莘县羊群存在弓形虫病流行,且有多种风险因素(羊群年龄、季节、养殖模式和场内是否养犬猫等)可影响羊弓形虫病流行。本研究为该地区羊弓形虫病防控提供了依据。In order to preliminarily investigate the prevalence and potential risk factors of sheep toxoplasmosis in Shenxian County,Shandong Province,a total of 1240 sheep serum samples were collected from 49 farms/households in the county from March 2023 to March 2024,the antibodies against T.gondi were detected using indirect hemagglutination assay(IHA)and relevant risk factors affecting the prevalence of the disease in this region were analyzed.The results showed that 103 positive serum samples were detected from 17 farms/households,the positive rates at farm/group and individual level were 34.69%(17/49)and 8.31%(103/1240),respectively,and highest in D Township,which were 71.43%(5/7)and 17.11%(32/187),respectively.It was further revealed that the positive rate of antibodies against sheep T.gondi was greatly different(P<0.05)depending on different ages,breeding modes and seasons,and the infection rate of sheep T.gondi was greatly affected(P<0.05)by the status whether there were dogs or cats on farms and the level of hygienic management,but with slight difference(P>0.05)among different genders of sheep.In conclusion,T.gondii was prevalent in Shenxian County,being affected by various risk factors(ages,seasons,breeding modes,whether there were dogs or cats on farms,etc).A scientific basis was provided for future prevention and control of sheep toxoplasmosis in the region.
