High resistance to carbapenems and cephalosporins was observed with Shigella sp. The other strains of enterobacteria isolated from newborns only, among which were identified: 7 (35%) Escherichia coli; 5 (25%) Klebsiella oxytoca; 5 (25%) Enterobacter sp, 3 (15%) Shigella sp. newborns without their mothers showed a variable resistance profile to the antibiotics tested.
