Resistance of group A beta-hemolytic streptococci to lincomycin and erythromycin.

abstract：:Gram-negative bacteria cause approximately 70% of the infections in intensive care units. A growing number of bacterial isolates responsible for these infections are resistant to currently available antibiotics and to many in development. Most agents under development are modifications of existing drug classes, which ...
