Group F β-hemolytic Streptococcus, Tonsillitis and Myocarditis

Abstract

A case of tonsillitis and myocarditis is reported, where the only positive microbiological finding was a throat swab growing group F beta-hemolytic streptococci. The patient made an uneventful recovery after treatment with benzylpenicillin and clindamycin.

Streptococcal Tonsillitis and Acute Streptococcal Myocarditis: An Unusual Combination Assessed by Cardiac Magnetic Resonance Imaging and Endomyocardial Biopsy

“…2 Apart from these studies, the rest of the literature includes only case reports, without cardiac MRI or endomyocardial biopsy evaluation. [8][9][10][11][12][13] To our knowledge, our study constitutes the largest series of patients with tonsillitis and concurrent myocarditis evaluated by both cardiac MRI and endomyocardial biopsy. Although all of our patients were taking penicillin during the development of myocarditis, hypersensitivity to peni cillin was not considered as a possible cause, because the patients recovered completely despite the continued penicillin therapy and none had evidence of a hypersensitivity reaction.…”
