Tetracycline resistance and tetM in pathogenic urogenital bacteria.

abstract：:The resistance mechanisms of methicillin-resistant strains of Staphylococcus saprophyticus were characterized. Penicillin-binding protein (PBP) studies demonstrated an inducible PBP identical to PBP 2a in the membranes of these isolates. The amount of beta-lactamase produced was minimal. PBP 2a is responsible for the ...
