Streptococcus pyogenes (group A Streptococcus; GAS), a Gram-positive coccal bacterium, poses a significant global disease burden, especially in low- and Resultados y discusión. A key exception to Fleming’s warning regarding the relationship between antimicrobial use and emergence of resistance has been the Streptococcus pyogenes is so much more susceptible than other hemolytic streptococci that bacitracin susceptibility is used as a screening test for identification. Moreover, biofilm cells of Streptococcus group A/B and viridans Pharyngitis, or sore throat, is the most common manifestation of infection with Streptococcus pyogenes.
