↵* Data are expressed as absolute numbers of positive S. epidermidis isolates for virulent genes in each child group under study and their percentages in brackets. Different superscript letters (a or b) in the same row indicate significant differences in the presence of virulent genes among active and non-active CD patients and control children on applying χ2 test (p<0.05).
