Lab M media for Clostridium
perfringens.
Lab M's Perfringens Agar-OPSP is designed for the enumeration
of Clostridium perfringens in foods, and the company's Perfringens
Agar Base (TSC) is used in the preparation of Tryptose Sulphite
Cycloserine (TSC) Agar for the enumeration and presumptive
identification of the organism.
Clostridium perfringens is widely distributed in the environment
and is part of the normal flora in human and animal intestines. Since
its spores can survive cooking and subsequently germinate to form
vegetative cells, it is also an important cause of food poisoning.

Perfringens Agar OPSP uses a combination of sulphadiazine,
oleandoymcin & polymyxin to achieve selectivity, whilst cycloserine
is used with the TSC formulation. Both OPSP and TSC combine sodium
metabisulphite & ferric ammonium citrate to form the basis of the
indicator system with which C. perfringens reduces sulphite, producing
the black colonies synonymous with these media. For lull details of Lab
