Abstrakt		We have used six independent polymerase chain reactions (A1-A3 and B1-B3) for amplificantion of the entire sequence of the two toxin genes tcdA and tcdB of several Clostridium difficile strains. With this approach we have detected (1) restriction site polymorphisms which are distributed all over the genes, and (2) deletions that could be found only in tcdA. Characteristic differences between strains were mainly focused to the 5' third of tcdB (B1 fragment) and/or the 3' third of tcdA (A3 fragment). The possible use of our approach for typing of C. difficile toxin genes is discussed.
