RESUMO
Throat cultures from an adult pharyngitis patient yielded Streptococcus pneumoniae as a single organism, with a very high bacterial count. The isolate was found to be macrolide and fluoroquinolone resistant, and the same strain was cultured from the patient's denture washing solution. Ceftriaxone therapy, a gradual reduction in the bacterial count and progressive clinical improvement proceeded at the same pace, so we labelled this clinical case as a pneumococcal pharyngitis.

We present two cases of exudative pharyngitis due to Streptococcus dysgalactiae subsp. equisimilis, Lancefield group G. While the participation of this organism as an agent of pharyngitis is well documented, we focus on failure of beta-lactam therapy, a phenomenon that is well described for pharyngitis due to Streptococcus pyogenes. Therefore, these case reports add to our knowledge of pharyngitis caused by non-S. pyogenes streptococci.
