Sensibilidad a trimetoprima-sulfametoxazol de Streptococcus pyogenes aislados de infecciones invasivas
Susceptibility of Streptococcus pyogenes isolated from invasive infections to trimethoprim-sulfamethoxazole

Medicina (B.Aires); 78 (5), 2018
Se cree erróneamente que los estreptococos del grupo A (EGA) son universalmente resistentes a trimetoprima-sulfametoxazol (TMS). Esto se debe a que la timidina presente en los medios habitualmente usados para determinar sensibilidad in vitro a antibióticos antagoniza el efecto antibiótico de TMS. El o...
