Supplement

Peptostreptococcus is fastidious,commensal and hard to isolate bacterium which requires proper methods of bacterial collection, transportation and cultivation in which cells is small, spherical and occurs in pairs or individually short chains. It produces large amount of lactic acids during carbohydratefermentation which is becomepathogenic or evensepticemic in immunosuppressed individuals.

Peptostreptococcus infections can takes place throughout the body including head, neck, central nervous system, abdomen, chest, skin, bone, soft tissues and joint but has been more predominantly found in soft tissue abscesses and subcutaneous as well as in diabetes-related foot ulcers and chronic infections of sinuses, mastoid, ears and teeth.

Peptostreptococcus is a synergistic bacterium which resolute by mutual induction of increased mortality, sepsis enhancement, augmented abscess inducement and enhancement of growth. Its capability to generates capsular materials is an importantvirulence mechanisms as well as by influencing interactions in diverse infections. It also implicated in endocarditis and bacteremia as well as paravalvular abscess and pericarditis.
