All genotypes were determined by PCR except for aatA, which was assayed by gene probe. Adherence is determined by the ability to exhibit stacked-brick AA in the HEp-2 adherence assay. Genes are categorized according to genomic location on the plasmid or chromosome.Ca, case; Co, control; M, male; F, female; astA, EAST1; setA, ShET1; cdtABC, cytolethal distending toxin; +, presence of adherence, biofilm, or indicated gene; −, absence of adherence, biofilm, or indicated gene.
