The study identifies the absence of the AbaR-type resistance island and the tet(A) gene in Acinetobacter baumannii A118, which may explain its susceptibility to various antibiotics. It also characterizes genes such as cat, bla_ADC, bla_OXA-51-like, carO, and pbp2, which are involved in resistance to chloramphenicol, cephalosporins, carbapenems, and other antibiotics.
