Streptococcus intermedius is a gram-positive bacterium belonging to the S. anginosus group, which is part of the normal human flora. This group of organisms is distinguished from other Streptococcal species by its virulence and shared ability to form abscesses. S. intermedius expresses several pyogenic exotoxins that contribute to its ability to form biofilms, lyse cells to traverse tissues, and liquefy pus. This report presents a case of osteomyelitis of the radius caused by S. intermedius. The patient required extensive and repeated debridement and was successfully treated with a first-generation cephalosporin.
