Initial studies on "six months disease" in sheep.

Enterotoxaemia in sheep due to Clostridium welchii type D was indicated by field and laboratory investigations in Nepal. Morphological, cultural, biochemical, biological and toxin-producing characteristics observed were used to type the isolates. In anaerobic meat medium, all isolates produced pinkish discoloration of meat. All the strains fermented lactose, maltose, dextrose and sucrose whereas, salicine was fermented only by 17 strains. All but five strains were MR negative. Out of 200 isolated, 166 produced both alpha and epsilon toxins and the remaining 34 non-toxogenic strains are likely to be variants which have lost their toxogenicity. Epidemiologically the local name "Six months disease" and enterotoxaemia are considered to be identical diseases.

ICMSF methods studies. XII. Comparative study for the enumeration of Clostridium perfringens in feces.

As the second phase of an international comparative study for the enumeration of Clostridium perfringens, four methods were compared for "total" and spore counts of C. perfringens in fecal specimens: the SFP (Shahidi-Ferguson perfringens) agar (A), TSC (tryptose-sulfite-cycloserine) agar (B), SC (sulfite-cycloserine) agar (C), and neomycin blood agar (D) methods. In both the total and spore count procedures, the confirmed C. perfringens counts in method D were lower than in methods A, B, and C. Little differences among methods were found in the percentages of presumptive colonies confirmed as C. perfringens. The nonspecific counts in methods A and D were generally greater than in B and C, but nonspecific microorganisms did not interfere in the enumeration of C. perfringens spores by any of the four methods. In overall performance, methods B and C were superior to A and D. The mean C. perfringens spore count was only 0.17 log lower than the mean total count. Spore counts alone are, therefore, adequate in investigations of C. perfringens outbreaks.

Clostridium perfringens toxin types from wild-caught Atlantic cod (Gadus morhua L.), determined by PCR and ELISA.

Ninety-five fecal samples from Atlantic cod (Gadus morhua L.), caught along the northern Norwegian coast, were examined bacteriologically for occurrence of C. perfringens. Isolates were examined by polymerase chain reaction (PCR) for genes encoding the four lethal toxins (alpha, beta, epsilon, and iota) for classification into toxin types and for genes encoding enterotoxin and the novel beta2 toxin for further subclassification. In addition, a commercial enzyme-linked immunosorbent assay (ELISA) kit for detection of C. perfringens alpha, beta, and epsilon toxin was used. Clostridium perfringens could be isolated in 37 fecal samples (38.9%) from cod. All isolates were C. perfringens toxin type A (alpha toxin positive) as determined by PCR and also ELISA. In addition, in isolates from two cod (2.1%) the gene encoding for beta2 toxin was found (A, beta2) by PCR. Genes encoding for beta, epsilon, and iota toxins and enterotoxin were not found. This is the first detection of C. perfringens alpha and beta2 toxin in cod and of beta2 toxin in fish in general. The origin of this bacterium in cod is discussed.

Multimicrobial sepsis including Clostridium perfringens after chemoembolization of a single liver metastasis from common bile duct cancer.

A 65-year-old woman underwent resection of a distal common bile duct carcinoma (Whipple's procedure). Twelve months later a single hepatic metastasis was detected and a chemoembolization was performed. Immediately after chemoembolization the patient developed a multimicrobial sepsis including Clostridium perfringens. CT scans depicted pathognomonic signs of gas-containing abscess in the necrotic liver metastasis. She was subsequently treated with broad-spectrum antibiotics, abscess drainage and hyperbaric oxygen therapy. We conclude that antibiotic prophylaxis is recommendable for chemoembolization of liver metastasis in patients with risk factors like intestinal biliary reflux (bilioenteric anastomosis or papillotomy and biliary stenting) and bile duct cancer, otherwise severe sepsis including clostridium bacteremia may occur.

Infection after depressed fracture in the west of Scotland.

Of 216 compound depressed fractures of the skull seen between the years 1974-1978, nine (4%) became infected. This is significantly less than the 10% found in previous years. Efforts are being intensified to train primary surgeons, stressing the importance of immediate referral and early treatment.
