Destructive Knee Joint Infection Caused byPeptostreptococcus micros: Importance of Early Microbiological Diagnosis

摘要

Peptostreptococcus micros is a commensal of the oral cavity and the genitourinary tract that rarely causes serious infections. A case of a destructive knee joint infection with rapid progress caused by P. micros is presented. The significance of the microbiological findings was initially not acknowledged, which contributed to a nonsuccessful clinical outcome.
