The etiology of nosocomial infections has markedly changed during past decades. Streptococci were the major nosocomial pathogens in the preantibiotic era. However, following the introduction and use of sulfonamides and penicillin, Staphylococcus aureus became the predominant pathogen in the 1950's. Aerobic gram negative rods gained prominence as nosocomial pathogens with widespread use of aminoglycosides and first generation cephalosporins through the early 1970's. Subsequent widespread use of broad spectrum cephalosporins was associated with changes in the frequency and etiology of nosocomial infections into the 1980's with the trend towards certain gram-positive pathogens. For example, in nosocomial bloodstream infections from 1980 to 1989 marked increases in the incidence of coagulase-negative staphylococci, S. aureus, enterococci, and Candida albicans infections occurred.
