Acholeplasma bactoclasticum sp. n., an Anaerobic Mycoplasma from the Bovine Rumen

A strain of a strictly anaerobic, filterable, bacteriolytic microorganism has been isolated from the bovine rumen. It has the microscopic and colonial morphology characteristic of mycoplasmas and is resistant to penicillin G. Sterols are not required for growth, and physiological properties show it to be distinct from Acholeplasma laidlawii, A. granularum, and A. axanthum. It is proposed that the organism be named Acholeplasma bactoclasticum sp. n. The type strain is ATCC 27112.
