Abstract
CONTRARY to current information, Provost and Doetsch1 reported recently that Caryophanon latum Peshkoff is a Gram-positive bacterium. Evidence cited for this contention, in addition to staining, included susceptibility to egg-white lysozyme and formation of ‘protoplasts’. The results of the investigation reported here indicate that protoplasts are formed when osmotically buffered suspensions of C. latum are exposed to egg-white lysozyme, and that these bodies possess many characteristics common to protoplasts of other Gram-positive bacteria.
