Radioautography enzyme bands for penicillin susceptibility among pneumococci
Radioautography enzyme bands for penicillin susceptibility among pneumococci
Five distinct bands, each representing a different enzyme, are detected after incubation with penicillin-susceptible pneumococci. Reduced or absent labeling of one or more of the five bands results when strains have reduced susceptibility to penicillin. Labeling can generally be restored after incubation with higher penicillin concentrations.
