Isolation of an L Type Culture from a Gram Positive Spore-Bearing Bacillus. ∗

Summary

Colonies similar in appearance and properties to the L type colonies of Gram negative bacilli were isolated from cultures of several large Gram positive bacilli. The L type colonies obtained from a spore-producing strain grew equally well from cultures obtained from heated spores as from the original culture, indicating that the L type colonies grew from the bacilli and were not an accidental contamination of the culture.
