Tsis tas li ntawd, puas yog Gram zoo cocci zoo ib yam li MRSA?
Cov kab mob aureus tau raug hu ua methicillin-resistant lossis MRSA . MRSA Cov kab mob feem ntau pom muaj kev tiv thaiv rau ntau yam tshuaj tua kab mob. Vim MRSA yog li tshuaj tua kab mob resistant (drug-resistant), nws yog hu ua "superbug" los ntawm qee cov neeg tshawb xyuas. aureus, grams - zoo cov kab mob uas tshwm sim hauv cov kab zoo li txiv hmab txiv ntoo hu ua cocci ua.
