Little is known about Toxoplasma gondii infection among cattle living in the Cerrado (Brazilian savanna) biome in Brazil. In particular, there is no epidemiological data relating to infection in quilombo lands, i.e. areas settled by Afro-descendants of escaped slaves. The aim of this study was to determine the prevalence, spatial distribution and risk factors associated with T. gondii infection among cattle in the Kalunga quilombo, in the Cerrado biome. Blood samples were collected from 1533 cattle for antibody detection using the indirect fluorescence antibody test (IFAT). The study area was subdivided into five macroregions to determine the spatial distribution of infection. An objective questionnaire was applied to the cattle owners to evaluate risk factors, which were analyzed using univariate analysis and logistic regression. The prevalence of T. gondii infection among cattle was 8.93% (137/1533), and antibodies were found in 49.6% of the herds (66/133), in all macroregions. The risk factors associated with T. gondii infection in cattle were the following: number of animals in the herd (OR: 30.56), purchase of cattle (OR: 2.57), age group (OR: 1.95) and average annual temperature (OR: 1.77). Thus, the occurrence rate, spatial distribution and risk factors associated with T. gondii infection among cattle in the Kalunga quilombola community are documented here, for the first time.
关于生活在巴西塞拉多（巴西热带稀树草原）生物群落中的牛的弓形虫感染情况，人们了解甚少。特别是，没有关于逃亡奴隶的非洲后裔定居地区（即基隆博土地）感染情况的流行病学数据。本研究的目的是确定塞拉多生物群落中卡伦加基隆博地区牛的弓形虫感染率、空间分布及相关风险因素。采集了1533头牛的血样，采用间接荧光抗体试验（IFAT）检测抗体。研究区域被划分为五个大区域以确定感染的空间分布。向牛主人发放了一份客观问卷以评估风险因素，并采用单因素分析和逻辑回归进行分析。牛群中弓形虫感染率为8.93%（137/1533），在所有大区域的牛群中，49.6%（66/133）检测到抗体。与牛弓形虫感染相关的风险因素如下：牛群数量（比值比：30.56）、购买牛（比值比：2.57）、年龄组（比值比：1.95）和年平均温度（比值比：1.77）。因此，本文首次记录了卡伦加基隆博社区牛群中弓形虫感染的发生率、空间分布及风险因素。
