Of the 200 Clostridium spp. known to exist, approximately 30 have been associated with human disease. Commonly found in soil, marine sediment and mammalian intestinal tracts, these gram-positive bacilli are known to cause infections ranging from cellulitis to septicemia. Isolates that are identified by clinical microbiology laboratories include Clostridium perfrigens species in 20–40% of cases. However, when Clostridium sporogenes is identified, is rarely considered to be pathogenic. We present a case of Clostridium sporogenes bacteremia secondary to lower limb cellulitis and osteomyelitis in an immunocompetent patient.
