title: [Propionibacterium avidum cutaneous abscess in a young immunocompetent].
abstract: Severe infections by Propionibacterium avidum are rare, we report a case of abscess of the root of the thigh in a young immunocompetent adult with no risk factor for infection with Propionibacterium sp. The liquid of abscess pus was inoculated immediately on culture media enriched and incubated under an atmosphere 5 to 10% CO2. The isolated strain was identified by API Coryne gallery (bioMérieux, Marcy l'étoile, France). An MIC of ciprofloxacin was performed by E-test (bioMérieux Marcy l'étoile). Cultivation led to the isolation after 3 days of incubation of pure and abundant culture of Propionibacterium avidum. To our knowledge, this is only the third documented case of infection by this organism in immunocompetent patient without iatrogenic risk. Thus, further studies on the pathogenicity of P. avidum are more than necessary.
