摘要: Introduction: Rickettsia typhi causes murine or endemic typhus, which is transmitted to humans primarily through flea bites contaminated with feces. Synanthropic and domestic animals also contribute the infection cycle of R. typhi. Cases typhus in were reported rural community Bolmay, Yucatan, Mexico, between 2007 2010.  Objective: To identify presence estimate frequency dogs from a locality previous reports humans.  Materials methods: Whole blood samples taken 128 dogs. Total DNA was extracted for use polymerase chain reaction (PCR) amplify fragments 17 kDa omp B genes confirms spp. The products sequenced, alignment analysis performed using BLAST tool.  Results: 5.5 % (7/128). identified 99% 100% homology genes, respectively.  Conclusion: We confirmed studied but at low frequency. However, there potential risk transmission humans.
