Heterogeneity among influenza H3N2 isolates recovered during an outbreak. Brief report.

Isolates of the H3N2 subtype recovered during an outbreak have been analyzed at the genomic and protein level. No reassortant genomes were detected. By T1-oligonucleotide fingerprinting of RNA segments coding for hemagglutinin (HA), nucleoprotein (NP), and neuraminidase (NA) two genotypes were found.
