Sixty-three consecutive streptococcal blood isolates from neutropenic patients, represented mainly by viridans group streptococci, were evaluated in vitro for antibiotic susceptibility. Of these isolates, 79.3% were highly susceptible to penicillin (MIC, less than or equal to 0.12 microgram/ml). Overall, imipenem was the most active agent, followed by teicoplanin and vancomycin. All other agents showed decreased activity against streptococcal isolates that were not highly susceptible to penicillin.
