Previous work suggested that domestic animals could act as a reservoir of epidemic typhus. To test this hypothesis, sera from buffaloes, camels, donkeys, goats, pigs and sheep in different parts of Egypt were submitted to the complement-fixation test, using the common soluble typhus antigen. The highest percentage of positive results was obtained with camel and donkey sera and the positivity rate was higher towards the end of the year than in June and July. Animals from the Western Desert area were more frequently positive than those from other regions. Attempts to isolate rickettsiae by intraperitoneal injection of guinea-pigs resulted in some febrile reactions, but so far no rickettsiae have been isolated.
以往的研究表明家畜可能是流行性斑疹伤寒的储存宿主。为验证这一假说，采集了埃及不同地区水牛、骆驼、驴、山羊、猪和绵羊的血清，使用常见的可溶性斑疹伤寒抗原进行补体结合试验。骆驼和驴血清的阳性结果百分比最高，且年末的阳性率高于6月和7月。来自西部沙漠地区的动物比其他地区的动物更频繁地出现阳性。通过豚鼠腹腔注射试图分离立克次体，引发了一些发热反应，但迄今为止尚未分离出立克次体。
