Tetracycline resistant (Tc R ) strains of three of the major species of strictly anaerobic rumen bacteria Megasphaera elsdenii, Selenomonas ruminantium and Butyrivibrio fibrisolvens , were recovered with an isolation medium containing 20 μg/ml tetracycline. Only two of 14 strains of these species from other sources, isolated without antibiotic selection, showed tetracycline resistance. Evidence was found for the presence of plasmids in two tetracycline‐resistant strains of M. elsdenii , and in some strains of S. ruminantium.
