Clostridium sordellii is found in the environment and occasionally in animal (including human) intestines and may cause myonecrosis and large outbreaks of enterotoxemia. A few cases of fatal clostridial infection in bears (Ursus spp.) have been described worldwide but none attributed to C. sordellii. We describe a fatal case of septicemia caused by C. sordellii in an illegally trapped brown bear (Ursus arctos). At necropsy, acute gangrenous myositis was the primary lesion. Serohemorrhagic edema was observed in the abdominal cavity, thorax, pericardium, and skeletal muscle, mostly affecting femoral, humeral, and scapular muscles. Hemorrhage was observed in the heart, skeletal muscles, stomach, and intestine. Liver, spleen, and kidney appeared with loss of consistency, hemorrhages, and edema. Microscopically, primary lesions were in skeletal muscle, stomach, and small intestine, with gram-positive, clostridial-like bacilli. Biochemical and molecular tests identified C. sordellii in cultures from liver, muscle, and intestine. Sequences showed a homology of >99% with the 16S rRNA gene sequence of C. sordellii. The severity of effects of the C. sordellii infection reveal the importance of this pathogen as a wildlife health risk with conservation concerns, as well as the need to consider possible infection with this pathogen in management actions involving immobilization, stress, or severe muscular activity of wild brown bears.

Clostridium perfringens (CP) is an anaerobic, Gram-positive bacillus associated with malignant diseases and near-term pregnancies. The necrotic tissue that results from these disease processes fuels the proliferation of CP, leading to gas gangrene and subsequently sepsis. Herein, we report a case of a 41-year-old female patient with a history of invasive molar pregnancy that was further complicated with a CP infection. Although past research has shown a link between Clostridium infection and choriocarcinoma (Chern-Horng and Hsieh, 1999), no previous cases of CP infection have been associated with invasive molar pregnancy. We also report complete resolution of the CP sepsis and its associated symptoms following the hysterectomy.

Clostridium perfringens sepsis with intravascular haemolysis is a catastrophic process with a reported mortality of between 90 to 100%. We successfully treated a case of severe clostridial infection with a liver abscess following laparoscopic cholecystectomy, the first to our knowledge. A 59-year-old man presented one week after an uneventful laparoscopic cholecystectomy with jaundice, peritonism, sepsis and acute renal failure. He was found to have a haemolytic anaemia, unconjugated hyperbilirubinemia and blood cultures grew Clostridium perfringens. A CT revealed a large gas forming abscess in the gallbladder fossa and right lobe of liver. He was treated with directed antibiotic therapy and underwent emergency laparotomy, drainage of the abscess and peritoneal washout. He required intensive care support, parenteral nutrition and inotropic support for a limited period. CT liver angiogram post op was normal. Continued renal dysfunction necessitated protracted haemofiltration. This resolved and the patient was discharged home at 2 months.

Clostridium septicum is a highly virulent pathogen which is associated with colorectal malignancy, hematological malignancy, immunosuppression, diabetes mellitus and cyclical neutropenia. Presentation may include disseminated clostridial infection in the form of septicemia, gas gangrene, and mycotic aortic aneurysms. We report the case of a 62-year-old female presenting with necrotizing fasciitis of her left thigh and subsequently developing rectal bleeding. While she was being treated with empiric antibiotics, her blood culture was found to be positive for C. septicum. We would like to highlight the importance of early colorectal cancer screening in minimizing the occurrence of undetected tumors which provide an optimal growth environment for C. septicum, leading to localized and/or remote infection.
