Mexican typhus virus can be passed through ticks by the method of rectal injection. The virus will remain alive in the ticks for at least 12 days. These studies, together with one of our preceding publications and the work of Dyer, demonstrate that there are at least three insects-bedbugs, fleas and ticks-which must be considered as possibilities in conveying typhus fever from an animal reservoir to man. Our work will be continued by a study of rats and mice caught in typhus regions such as Mexico City and its immediate vicinity, with a search for the virus in these rodents as well as an analysis of the insects found upon them or in the localities in which they are concentrated.
墨西哥斑疹伤寒病毒可通过直肠注射的方式在蜱中传播。病毒在蜱中的存活时间至少为 12 天。这些研究与我们之前的一篇出版物和 Dyer 的工作一起，证明至少有三种昆虫——臭虫、跳蚤和蜱——必须被视为将斑疹伤寒从动物宿主传播给人类的可能性。我们的工作将继续通过对在墨西哥城及其周边地区等斑疹伤寒疫区捕获的大鼠和小鼠进行研究来进行，在这些啮齿动物中寻找病毒，并分析在它们身上或在它们集中的地方发现的昆虫。
