Description
Summary:Cultural, biochemical, and serologic studies conducted with the simplest medium and by the use of the simplest technic with 53 strains concerned in human and animal botulism have shown that the action on native protein, the peptolytic property, the fermentation reactions, the agglutination and the toxin-antitoxin neutralization test are of importance for classification. On the basis of cultural and peptolytic behavior the anaerobes are arranged in two groups: Clostridium botulinum (nonovolytic, Sörensen figures 1 to 6) and C1. parabotulinum (ovolytic, Sörensen figures 18 to 21). The agglutination tests subdivide the four, possibly five, toxicologic types (A, B, Cα, Cβ and D) into at least 15 subgroups while the fermentation reactions place the strains in at least 8 groups. Strains fundamentally different from those commonly encountered on the North American continent have been isolated in Europe, Australia and Africa.
