Brucellosis is a disease of high morbidity that affects several animal species, is transmitted to humans and, therefore, is a zoonosis. It is caused by bacteria of the genus Brucella. In this study we aim to determine seroprevalence, risk factors, and spatial distribution of caprine brucellosis in 14 municipalities in the central region of the state of Veracruz.
This cross-stratified multistage study was conducted between 2009 and 2012. It included 572 animals of 81 production units selected by consensus according to the value tables of Cannon and Roe. The diagnosis was by Card Testing and Radial Immunodiffusion. The seroprevalence was determined with the VassarStats® risk factor program and odds.
The overall seroprevalence was 0.52% (95% CI: 0.13-1.65) and production units 2.47% (95% CI: 0.43-9.46). They were identified as risk factor for infection, production units in feedlot system and Card Testing seroconversion to vaccine against brucellosis; and as a protective factor, vaccination.
Seroprevalence and distribution of goat brucellosis is low, the intensive system is a risk, and according with the Health Ministry in order that human cases are scarce.
布鲁氏菌病是一种发病率很高的疾病，可感染多种动物物种，并可传播给人类，因此是一种人畜共患病。它由布鲁氏菌属细菌引起。在本研究中，我们旨在确定韦拉克鲁斯州中部地区14个市山羊布鲁氏菌病的血清阳性率、危险因素和空间分布。
这项交叉分层多阶段研究于2009年至2012年进行。根据坎农和罗伊的价值表，通过共识选择了81个生产单位的572只动物。诊断采用卡片检测和放射免疫扩散法。血清阳性率通过VassarStats®危险因素程序和比值比来确定。
总体血清阳性率为0.52%（95%可信区间：0.13 - 1.65），生产单位的血清阳性率为2.47%（95%可信区间：0.43 - 9.46）。被确定为感染危险因素的有饲养场系统中的生产单位以及卡片检测中布鲁氏菌病疫苗血清转化；而疫苗接种则是一个保护因素。
山羊布鲁氏菌病的血清阳性率和分布较低，集约化养殖系统是一个风险因素，且根据卫生部的说法，这样人类病例就较为稀少。
