An assessment of thermal stability of Clostridium difficile toxoid formulations.

Strains of Clostridium difficile produce toxins A and B that can cause diarrhoea and pseudomembranous colitis. Currently, there is no preventative therapy for this infection but antibodies to the toxins provide protection, therefore a toxoid-based vaccine is needed. To evaluate thermal stability, a lyophilized and liquid formulation of toxoids A and B were… CONTINUE READING
