Abstract
We show here how pathogenicity islands can be analysed using GenomeAtlases, which is a method for visualising repeats, DNA structural characteristics, and base composition of chromosomes and plasmids. We have applied this method to the E. coliplasmid pO157, and the Y. pestisplasmid pPCP1. In both cases pathogenic genes were shown to differ in A+Tcontent and structural properties. Furthermore, examination of an antibiotic resistance gene cluster from S. typhimuriumshowed that the same was true for genes encoding antibiotic resistance.
