为了研究家庭庭院饲养的家畜是否可能通过动物预防保护居住者免受疟疾的侵害，对巴基斯坦和阿富汗难民村的学童进行了寄生虫流行情况调查，并根据每个儿童家庭是否养牛进行了分析。养牛家庭的儿童寄生虫感染率（15.2%）显著高于不养牛家庭的儿童（9.5%）。不同村庄之间的流行率比较显示，寄生虫率与拥有牛的家庭比例呈正相关。后一项发现支持了Sota-Mogi理论模型的预测，即当病媒是嗜动物性的、感染率低、人与牛的比例高时，家畜可以增加而不是减少疟疾的传播。所有这些条件都适用于研究区。
To examine the possibility that domestic cattle kept in house courtyards might protect occupants against malaria through zooprophylaxis, parasite prevalence surveys were conducted of schoolchildren in Pakistani and Afghan refugee villages and analysed according to whether each child's family kept cattle. Parasite prevalence (15.2%) was significantly greater among children of families which kept cattle than among those which did not (9.5%). Comparison of prevalence between different villages revealed a positive correlation between parasite rates and the proportion of families owning cattle. The latter finding supports the prediction of the Sota-Mogi theoretical model that domestic animals can enhance rather than reduce malaria transmission when vectors are zoophilic, the infection rate low, and the human:cattle ratio high. All these conditions applied in the study area.
