The spread of drug-resistant influenza viruses type A to close contacts in families, schools, and nursing homes has been well documented. To investigate whether drug-resistant influenza viruses circulate in the general population, 2017 isolates colle

An avian H5N1 influenza A virus (A/Hong Kong/156/97) was isolated from a tracheal aspirate obtained from a 3-year-old child in Hong Kong with a fatal illness consistent with influenza. Serologic analysis indicated the presence of an H5 hemagglutinin.

SummaryFour influenza type B viruses isolated in Russia during periods of relatively low (1987–8) or high (1990–1) influenza B activity were characterized antigenically using a microneutralization assay. These isolates were antigenically similar

The antigenic and genetic characteristics of the haemagglutinins of influenza type B viruses isolated since 1988 during periods of both widespread activity (1990/1991) and sporadic activity (1989/1990) were examined using microneutralization tests an

The sequence of the 1600 3' terminal nucleotides of the RNA of rubella virus was determined from cDNA synthesized from both virion and intracellular RNA using reverse transcriptase and an oligodeoxythymidine primer and cloned into a bacterial plasmid

The generation of defective-interfering (DI) particles by rubella virus during serial undiluted passage and persistent infection in Vero cells was studied. A series of 24 serial undiluted passages was initiated with plaque-purified virus. The virus t
