2. FIG. 1
Prevalence of certain virulence-associated genes and pathogenicity islands among Escherichia coli group B2 strains obtained from Pakistani and Swedish infants. Pakistani B2 strains (n = 19) were identified using multiplex PCR, related to previously published data on virulence factor gene carriage [19], and compared with data obtained using the same methodology for the study of faecal B2 strains (n = 69) from Swedish infants [16]. Comparisons were made using Fisher's exact test. Prevalences that were significantly reduced in Pakistani as compared with Swedish B2 strains are indicated as follows: *p <0.05, **p <0.01, ***p <0.001.
