Relationship between Toxigenicity and Sporulating Potency of Clostridium Novyi.

Some properties of heat-resistant and heat-sensitive strains of Clostridium perfringens. I. Heat resistance and toxigenicity.

Heat resistance at 100 C (D-values), sporulating ratios, toxigenicity for mice, and lecithinase activity (as micrograms per milliliter of enzyme, ascertained by the lecithovitellin reaction) were determined for four strains of Clostridium perfringens. A definite inverse relationship between thermal resistance and toxigenicity was found. The D-values ranged from 17.6 for the most heat-resistant ...

Plasmidome Interchange between Clostridium botulinum, Clostridium novyi and Clostridium haemolyticum Converts Strains of Independent Lineages into Distinctly Different Pathogens

Clostridium botulinum (group III), Clostridium novyi and Clostridium haemolyticum are well-known pathogens causing animal botulism, gas gangrene/black disease, and bacillary hemoglobinuria, respectively. A close genetic relationship exists between the species, which has resulted in the collective term C. novyi sensu lato. The pathogenic traits in these species, e.g., the botulinum neurotoxin an...

Biochemical Properties of the Toxins of Clostridium novyi and Clostridium hemolyticum.

The report of Oakley, Warrack, and Clarke (1947) on the toxins of the Clostridium novyi (oedematiens) group and of Clostridium hemolyticum indicates the complexity of this topic and presents the pertinent historical data. It is known that the toxins C. novyi and C. hemolyticum involve a lecithinase catalyzing the hydrolysis of lecithin to phosphorylcholine and a diglyceride. In view of the exis...
