Cl. welchii Infection of the Eye

Pseudomembranous enterocolitis with jujunal perforation associated with CL. Welchii infection.

Food poisoning due to Cl. welchii.

THE report of the Medical Research Council for the year 1951-2 records that one of the most recent additions to the list of recognized causative organisms of food-poisoning is a heat-resistant variant of Cl. welchii. The present paper describes an outbreak of food-poisoning in an army camp in which there is evidence to presume that Cl. welchii was responsible. In a comprehensive study of clostr...

Free-sporing Cl. welchii in ordinary laboratory media and conditions.

A strain of Clostridium welchii produced spores in ordinary blood agar plates. Investigations confirmed that it was the character of this particular strain and that the laboratory media were not inducing sporulation. During a period of 12 months a total of 100 strains of Cl. welchii were studied. None of them produced spores in ordinary laboratory media and conditions when examined microscopica...

A Study of the Competition of Lecithin and Antitoxin for Cl. Welchii Lecithinase

Lecithin has been found to interfere with the combining reaction of Cl. welchii alpha toxin (lecithinase) and its antitoxin. If the lecithinase is first brought into contact with lecithin, and the antitoxin is then added, the antitoxin fails to stop the enzymatic reaction, but gradually decelerates it. If the lecithinase is brought into contact with both lecithin and antitoxin at the same insta...

Clostridium welchii and Bacillus cereus infection and intoxication BETTY

Clostridium welchii type A is a common agent of food poisoning when allowed to proliferate to large numbers in cooked foods, usually meat and poultry. The main factors of importance are survival of the spores, frequently found on raw products, through the cooking process, and possible contamination of cooked meats transferred to unclean containers; subsequent germination of spores and rapid mul...
