The objective of the study was to identify the seroprevalence of anti-Toxoplasma gondii antibodies in sheep herds from 3 municipalities from Jalisco, Mexico, as well as estimate the association between seroprevalence and certain factors presents in the farms. In total, 12 sheep farms that maintain only hair breeds were included in the work. From these farms, 336 blood samples were collected, corresponding 324 to ewes and 12 rams. Serum samples were subjected to ELISA test, and the association between the frequency of antibodies and some potential risk factors was estimated. The overall seroprevalence to anti-T. gondii antibodies in the population studied was 17.8% (60/336; 95% confidence interval [C.I.] 14-22), all farms had positive animals, and the seroprevalence of antibodies ranged between 7 to 32%. Seroprevalence in specific municipalities was 18.7% in Lagos de Moreno, 17.8% in Encarnación de Díaz, and 16.9% in San Juan de los Lagos. Seroprevalence in ewes was 17.5% (57/324; 95% C.I. 13-22), and seroprevalence in rams was 25% (3/12; 95% C.I. 6-57), while among breeds it was 17.8% in Pelibuey (20/112; 95% C.I. 11-26), 16.6% in Kathadin (14/84; 95% C.I. 9-26), 15.4% in Blackbelly (13/84; 95% C.I. 8-25), and 23.2% in Dorper (13/56; 95% C.I. 13-36); no differences were observed among breeds (p < 0.05). The presence of cats on the farms was associated with seroprevalence (odds ratio [OR] 2.8; 95% C.I. 1.8-7.3, p < 0.001), as was the absence of a rodent-control program (OR 1.5; 95% C.I. 0.8-3.2, p < 0.05). No other factors were identified as associated with seroprevalence.

墨西哥哈利斯科州绵羊的弓形虫感染的血清阳性率及相关因素。

该研究的目的是鉴定来自墨西哥哈利斯科州3个市的绵羊群中弓形虫抗弓形虫抗体的血清阳性率,并估算血清阳性率与农场中某些因素之间的关联。总的来说,这项工作包括了12个仅保留毛发品种的养羊场。从这些农场收集了336个血液样本,相当于324头母羊和12头公羊。对血清样品进行ELISA测试,并评估抗体频率与某些潜在危险因素之间的关联。总体血清阳性率为抗-T。研究人群中的刚地抗体为17.8%(60/336; 95%置信区间[CI] 14-22),所有农场的动物均为阳性,抗体的血清阳性率在7%至32%之间。在拉各斯·德·莫雷诺,特定城市的血清阳性率在拉各斯·德·莫雷诺为18.7%,在恩卡纳西翁·德·迪亚兹为17.8%,在圣胡安·德洛斯拉各斯为16.9%。母羊的血清阳性率是17.5%(57/324; 95%CI 13-22),公羊的血清阳性率是25%(3/12; 95%CI 6-57),而在Pelibuey中则是17.8%(20) / 112; 95%CI 11-26),Kathadin(16/84; 95%CI 9-26),16.6%在Blackbelly(13/84; 95%CI 8-25),和Dorper 23.2% (13/56; 95%CI 13-36);品种间未观察到差异(p <0.05)。农场中猫的存在与血清阳性率相关(优势比[OR] 2.8; 95%CI 1.8-7.3,p <0.001),以及缺少啮齿动物控制计划的情况(OR 1.5; 95%CI 0.8- 3.2,p <0.05)。尚无其他因素与血清阳性率相关。圣胡安·德·洛斯·拉各斯的9%。母羊的血清阳性率是17.5%(57/324; 95%CI 13-22),公羊的血清阳性率是25%(3/12; 95%CI 6-57),而在Pelibuey中则是17.8%(20) / 112; 95%CI 11-26),Kathadin(16/84; 95%CI 9-26),16.6%在Blackbelly(13/84; 95%CI 8-25),和Dorper 23.2% (13/56; 95%CI 13-36);品种间未观察到差异(p <0.05)。农场中猫的存在与血清阳性率相关(优势比[OR] 2.8; 95%CI 1.8-7.3,p <0.001),以及缺少啮齿动物控制计划的情况(OR 1.5; 95%CI 0.8- 3.2,p <0.05)。尚无其他因素与血清阳性率相关。圣胡安德洛斯拉各斯的9%。母羊的血清阳性率是17.5%(57/324; 95%CI 13-22),公羊的血清阳性率是25%(3/12; 95%CI 6-57),而在Pelibuey中则是17.8%(20) / 112; 95%CI 11-26),Kathadin(16/84; 95%CI 9-26),16.6%在Blackbelly(13/84; 95%CI 8-25),和Dorper 23.2% (13/56; 95%CI 13-36);品种间未观察到差异(p <0.05)。农场中猫的存在与血清阳性率相关(优势比[OR] 2.8; 95%CI 1.8-7.3,p <0.001),以及缺少啮齿动物控制计划的情况(OR 1.5; 95%CI 0.8- 3.2,p <0.05)。尚无其他因素与血清阳性率相关。Pelibuey(8%)(20/112; 95%CI 11-26),Kathadin(16/84; 95%CI 9-26),16.4%Blackbelly(13/84; 95%CI 8-25) ,以及在Dorper中的23.2%(13/56; 95%CI 13-36);品种间未观察到差异(p <0.05)。农场中猫的存在与血清阳性率相关(优势比[OR] 2.8; 95%CI 1.8-7.3,p <0.001),以及缺少啮齿动物控制计划的情况(OR 1.5; 95%CI 0.8- 3.2,p <0.05)。尚无其他因素与血清阳性率相关。Pelibuey(8%)(20/112; 95%CI 11-26),Kathadin(16/84; 95%CI 9-26),16.4%Blackbelly(13/84; 95%CI 8-25) ,以及在Dorper中的23.2%(13/56; 95%CI 13-36);品种间未观察到差异(p <0.05)。农场中猫的存在与血清阳性率相关(优势比[OR] 2.8; 95%CI 1.8-7.3,p <0.001),以及缺少啮齿动物控制计划的情况(OR 1.5; 95%CI 0.8- 3.2,p <0.05)。尚无其他因素与血清阳性率相关。缺少啮齿动物控制程序(OR 1.5; 95%CI 0.8-3.2,p <0.05)。尚无其他因素与血清阳性率相关。缺少啮齿动物控制程序(OR 1.5; 95%CI 0.8-3.2,p <0.05)。尚无其他因素与血清阳性率相关。
