To the Editor: We appreciate Dr. Centor's1 observations and comments on the literature regarding the role of non-group A strep in acute pharyngitis. In our population, group B was associated with 3 of the 4 classic criteria—fever, cervical adenopathy, and exudates—but not absence of cough (Figure 5 in our article2), suggesting that it may also represent a pathogen. Given the concerns for group B strep infection in the young adult population that includes pregnant women this certainly warrants further investigation, which we hope to pursue.
