Prevalence of rabies virus infection and rabies antibody in stray dogs: a survey in Bangkok, Thailand.

To investigate the rabies antigen and antibody prevalences among stray dogs in Bangkok, Thailand, we took both a saliva and serum sample from each of 3314 stray dogs captured once each between December 2003 and June 2004. One 2-year-old female was antigen positive in the latex-agglutination test and confirmed by reverse transcription-polymerase chain reaction. The overall antibody seroprevalence from the enzyme-linked immunosorbent assay that we used was 62% (95% CI: 54, 70%).
