aAccounting for 23.9% (93 of 388) of the global population of the villages studied and not significantly different from it for male/female ratio or age distribution.
bBacteria with intermediate susceptibility were categorized as resistant.
cExtended spectrum β-lactamase E. coli.
dAcinetobacter baumanni: 9 (all with the same susceptibility pattern including susceptibility to ureidopenicillins, third generation cephalosporins, aminoglycosides, and quinolones) and Ochrobactrum spp. (identified by 16s RNA genes sequencing): 2.
