J Vector Ecol. 2008 Jun;33(1):205-7. doi: 10.3376/1081-1710(2008)33[205:seotgr]2.0.co;2.

Abstract

We tested sera from 176 homeless people in Houston for antibodies against typhus group rickettsiae (TGR). Sera from 19 homeless people were reactive to TGR antigens by ELISA and IFA. Two people had antibodies against Rickettsia prowazekii (epidemic typhus) and the remaining 17 had antibodies against Rickettsia typhi (murine typhus).
