متن کاملDouble stranded RNA virus in South African Trichomonas vaginalis isolates.
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 po...

متن کاملCharacterization of double-stranded RNA satellites associated with the Trichomonas vaginalis virus.
Three small and distinct satellite double-stranded RNAs (dsRNAs) denoted s1, s1', and s2 were recently described for a Trichomonas vaginalis isolate harboring a dsRNA virus. Since characterization of these satellite dsRNAs might provide insight into the virus replication cycle and virus-host interactions, full-length cDNAs to s1 and s1' dsRNAs were synthesized and sequenced. s1 dsRNA has 688 bp...
