Abstract

A total of 100 Jordanian clinical isolates was analysed for the presence of the enterotoxin genes , , , and using multiplex PCR. Twenty-three isolates (23 %) were potentially enterotoxigenic. The prevalence of , and plus among the total clinical isolates was 15, 4 and 4 %, respectively. None of the isolates harboured , or genes. isolates were subjected to DNA fingerprinting by randomly amplified polymorphic DNA (RAPD) analysis to test whether isolates harbouring the toxin genes were genetically clustered. A total of 13 genotypes was identified at a 47 % similarity level. Genotypes I and V accounted for the largest number of enterotoxigenic isolates (19 %). This study has demonstrated the genetic diversity of Jordanian clinical isolates and shown that the presence of the toxin genes is not genotype specific.
