Severe necrotizing anaerobic infections carry a high mortality. From a retrospective review of 17 cases of gas gangrene, necrotizing fasciitis and nonclostridial myonecrosis seen at the Victoria and University hospitals in London, Ontario, between Jan. 1, 1975 and Dec. 31, 1977, the most common antecedent was found to be minor trauma. Location of the infection varied; the scrotum and perineum were most commonly involved. Local findings were most frequently edema, skin tenderness and induration. Mixed infections predominated with a pure growth of Clostridium sp. occurring in only three cases. The overall mortality was 29%. The mainstay of treatment after initial administration of fluids followed by broad-spectrum antibiotics is early aggressive surgical debridement of all necrotic tissue.

Necrotic enteritis (NE), caused by the gram-positive, anaerobic bacterium, Clostridium perfringens, results in an estimated $6 billion in annual economic losses to the global poultry industry. C. perfringens is part of the normal microflora of the poultry gastrointestinal tract, but damage to the intestinal epithelium can lead to increased cell proliferation and production of toxins which gives rise to disease.

Shoulder abscesses, commonly resulting from bacterial infections, can occasionally present with atypical etiologies and delayed onset. We report a rare case of a massive polymicrobial shoulder abscess developing two decades after an insect bite, emphasizing its clinical presentation, diagnostic approach, and surgical management. A 65-year-old female presented with severe, progressively worsening right shoulder pain, a 20 cm swelling, and purulent discharge persisting for 15 days.

Emphysematous pyelonephritis is a necrotizing infection of the renal parenchyma by gas-forming organisms, with a risk of the gas extending into peri-nephric or para-renal spaces and in advanced cases, the involvement may be extensive and bilateral. It is a common complication in patients with long-term diabetes, primarily caused by Gram-negative organisms or, in some cases, anaerobes. The diagnosis of emphysematous pyelonephritis is made by clinical features and confirmed by computed tomography.
