Abstract

In total, 901 dairy cow sera and data were collected from 51 farms in Nakhon Pathom, Ratchaburi and Kanchanaburi provinces (Western Region of Thailand). Serum samples were processed via the multispecies ELISA method to detect IgG antibodies against Toxoplasma gondii infection. The results demonstrated that the calculated true prevalence was 1.48% (95% CI, 0.64-2.75%) for the individual-level and 29.41% (95% CI, 18.71-43%) for the farm-level. The univariate risk factor analysis showed that the number of total owned cats, the presence of stray cats, and the frequency of cleaning per day were significant factors (p < 0.2). These three factors were subjected to logistic regression analysis, and the results revealed that the frequency of cleaning farms per day was a potential risk factor for T. gondii-seropositive farms (OR = 2.745, 95% CI, 1.15-8.69, p = 0.02). The frequency of cleaning might increase the T. gondii oocyst distribution within the barn area, thus increasing the possibility of infection. Our findings show that T. gondii continues to circulate in the dairy cow population in the western part of Thailand. The presence of cats on farms was not found to be associated with T. gondii infection, but the high frequency of cleaning the floor was, and contributed to the potential risk of infection.

泰国西部地区奶牛弓形虫感染的流行率和风险因素。
从泰国西部地区那空帕通府、叻丕府和北碧府的 51 个牧场共收集了 901 份奶牛血清和数据。通过多物种酶联免疫吸附法处理血清样本,检测弓形虫感染的 IgG 抗体。结果表明,计算得出的个体真实感染率为 1.48%(95% CI,0.64-2.75%),农场真实感染率为 29.41%(95% CI,18.71-43%)。单变量风险因素分析表明,所有养猫数量、是否有流浪猫以及每天的清洁频率是显著的风险因素(P
