Evidence that Tn5565, which includes the enterotoxin gene in Clostridium perfringens, can have a circular form which may be a transposition intermediate
Abstract
The Clostridium perfringens enterotoxin gene is on a transposon-like element, Tn5565, integrated in the chromosome in human food poisoning strains. The flanking IS elements, IS1470 A and B, are related to IS30. The IS element found in the transposon, IS1469, is related to IS200 and has been found upstream of cpe in all Type A strains. PCR and sequencing studies from cell extracts and plasmid isolations of C. perfringens indicate that Tn5565 can form a circular form with the tandem repeat (IS1470)2, similar to the transposition intermediates described for a number of IS elements.
