Isolation of Pleuropneumonia-like Organisms from H. influenzae with the Aid of Penicillin.

Abstract

With the aid of penicillin, a strain of pleuropneumonia-like organism has been isolated from a culture of Hemophilus influenzae. This strain could be kept in continuous cultivation. Colonies of similar organisms were seen in 3 other cultures of H. influen-zae, but their propogation in pure culture was not successful.
