<i>Streptococcus Pneumoniae</i> Isolates Relatively Insensitive to Penicillin G Recovered from Patients in Switzerland

Abstract

The sensitivity to penicillin G of pneumococci isolated in Switzerland has been determined by the quantitative tube dilution method. 3 out of 100 strains were relatively insensitive to this antibiotic (minimum inhibitory concentration greater than 0.1 μg/ml), thus confirming observations already made in other countries. These results underline the necessity of routinely testing the sensitivity of pneumococci to penicillin G.
