A reverse transcription nested PCR (RT-PCR) assay for the detection of
rubella virus RNA using primers from the E1 open reading frame was
established. This assay was found to be sensitive (detecting approximately
two synthetic RNA copies and RNA extracted from 0.1 50% tissue culture
infective dose of rubella virus) and specific; five wild- type rubella
strains and four vaccine strains were detected, and no nonspecific
amplification of 16 other RNA viruses or RNAs from seven cell types
occurred. Rubella virus RNA was detected in 12 pharyngeal swabs from
patients with serologically confirmed rubella; these RT-PCR results were in
complete agreement with virus isolation. Analysis of products of conception
obtained after confirmed primary maternal rubella infection by RT-PCR gave
92% agreement (12 of 13 samples) with virus isolation. No false-positive
results were obtained. The potential use of this assay for prenatal
diagnosis of congenital rubella infection and for investigating aspects of
the pathogenesis of chronic disease is discussed.
