Abstract
Clostridium difficile is the prime etiologic agent in the production of pseudomembranous colitis by its powerful cytotoxin. The most common test for the toxin is a tissue culture method with neutralization of cytopathic effect by a C. difficile antiserum. This method is expensive and requires a minimum of 72 hours before results can be obtained. Attempts to create a rapid method, counterimmunoelectrophoresis, enzyme-linked immunosorbent, latex agglutination, and fluorescent antibody test are fraught with many problems. This report describes a rapid method for the identification of C. difficile, using gas-liquid chromatography (GLC) for the demonstration of caproic acid, a product of the organisms fatty acid metabolism.
