Trends in the distribution of Staphylococcus aureus phage patterns in New York State during 1966-1975

The phage patterns of 15 790 S. aureus isolates collected from human sources in New York State (exclusive of New York City) during the 10-year period 1966-1975 were analysed. The results showed changes in the distribution of phage groups and a steadily increasing incidence of nontypable S. aureus.
