title: Acute glomerulonephritis in three siblings and suspected emm49-type Streptococcus pyogenes infection.
abstract: Three siblings with poststreptococcal acute glomerulonephritis are presented. Streptococcal infection, impetigo, and pharyngitis preceded the acute glomerulonephritis. In one patient, emm49-type Streptococcus pyogenes was isolated, a strain which has not been reported as nephritogenic in Japan.
