The hypervirulent polymerase chain reaction (PCR) ribotype 027 strain of Clostridium difficile produces toxins A, B and a binary
toxin. Toxin detection kits are commonly used in diagnostic laboratories, but have been unsuccessful in detecting all of the
relevant C. difficile strains, and the toxins produced. In this study, conventional PCR was used to detect the presence of the genes
of toxin A, toxin B and the binary toxin of C. difficile. Eighty-four frozen (collected between 2006-2007) and 13 fresh (collected in
2010) stool specimens, obtained in Pretoria, were analysed. The genes for toxin A, toxin B and the binary toxin were detected in
one of the fresh stool specimens. This may have implications for healthcare facilities, and suggests the possible emergence of
the highly virulent PCR ribotype 027 strain of C. difficile in Pretoria. This emphasises the importance of continuous surveillance
and monitoring of C. difficile outbreaks.
