is a protozoan parasite that infects several species of animals (domestic and wild) and is one of the most common causes of abortion in cattle worldwide. To better understand the epidemiological chain of neosporosis, update the disease status and propose control measures to improve milk production in Rio Grande do Sul (RS), the present study aimed to evaluate the seroprevalence of and its distribution in different municipalities of Rio Grande do Sul, Southern RS, Brazil, and determine the factors associated with exposure to in small dairy cattle producers in this region. Cattle from 51 dairy farms located in nine municipalities in the southern region of RS were included in this study. Small dairy farmers were interviewed to collect information about the characteristics of their herds. The association between potential associated factors and seropositivity in cattle was assessed using a logistic regression model with a generalized estimating equation. Seroprevalence in individual animals and between herds was 33.9% (95% CI = 28.1-39.9) (121/309) and 80.4% (95% CI = 67.5-88.9) (41/51), respectively. The high seroprevalence found indicates that cattle are susceptible to exposure by in a widespread manner in the Pelotas microregion. Furthermore, the sanitary management of cattle, the adaptation of tools that can improve the milk extraction technique and the technical monitoring of professionals who work on the properties can be effective alternatives for controlling
是一种原生动物寄生虫，可感染多种动物（家养和野生），是全球牛流产最常见的原因之一。为了更好地了解新孢子虫病的流行病学链，更新疾病状况并提出控制措施以提高南里奥格兰德州（RS）的牛奶产量，本研究旨在评估巴西南里奥格兰德州不同市的新孢子虫血清阳性率及其分布，并确定该地区小型奶牛养殖户中与新孢子虫暴露相关的因素。本研究纳入了来自RS南部地区9个市的51个奶牛场的牛。对小型奶农进行了访谈，以收集有关其畜群特征的信息。使用具有广义估计方程的逻辑回归模型评估牛潜在相关因素与血清阳性之间的关联。个体动物和畜群之间的血清阳性率分别为33.9%（95%CI = 28.1 - 39.9）（121/309）和80.4%（95%CI = 67.5 - 88.9）（41/51）。发现的高血清阳性率表明，在佩洛塔斯微区域，牛广泛易受新孢子虫暴露的影响。此外，牛的卫生管理、改进挤奶技术的工具的适配以及对养殖场工作人员的技术监测可能是控制的有效替代方法
