Clostridium difficile and its toxins

An investigation of Clostridium difficile has shown :

1. that the organism is resistant to cresols and phenolq
and may be grown from material grossly contaminated with
other organisms by culture in media containing these
substances; strains isolated before this method was
evised are also resistant to cresols and phenol;

2. that the organism divides into four daughter cells;

3. that each strain examined has a different strain specific
agglutinogen, and that the strains are otherwise
antigenically complex;

4. that the sugar reactions are fairly consistent

5. that gelatin is liquefied by all available strains in
three weeks; and that apart from this there is no
proteolytic activity

6. that the hyaluronidase produced by all strains is
antigenically uniform? and so is the lethal toxin;

7. and that the 'haemolysin' is almost certainly complex.
