Aims: To screen Trichomonas vaginalis isolates from South Africa for the presence of a small double stranded RNA virus designated T vaginalis virus (TVV).
Methods: TVV was detected by simultaneous extraction of DNA and RNA, and its presence confirmed by electron microscopy and nuclease digestions.
Results: TVV was detected in 59 of 72 (81.9%) isolates.
Conclusions: These results indicate a possible higher infection rate of South African T vaginalis isolates by the double stranded RNA virus than has been reported for isolates elsewhere.
Keywords: Trichomonas vaginalis virus; double stranded RNA virus; sexually transmitted diseases
