Infectious myositis is rather uncommon. When caused by anaerobic organ
isms, myositis is usually polymicrobial, Trauma, ischemia, or a contig
uous focus of infection is often an antecedent of myositis. We report
a case of monomicrobial veillonella myositis in an immunocompromised p
atient. The infection responded to debridement and therapy with metron
idazole.
