Reversal of Penicillin-Induced L-Phase Growth of Haemophilus influenzae by Spermine and Its Effects on Antibiotic Susceptibility.

Abstract

Spermine at a concentration of 0.001 m initiated the reversion of penicillin-induced L-phase growth of Haemophilus influenzae to bacillary growth on penicillin L-phase medium. Reversion of L-phase colonies to bacillary colonies required 3 to 5 days. This spermine reversal of variant growth also occurred on penicillin induction medium in the presence of… (More)
