Key Findings

The study identified several beta-lactamase genes (blaPER-2, blaOXA-58, blaTEM-1, and blaOXA-498) along with other resistance determinants such as strA, strB, ereA, sul1, and aacC2 in the Acinetobacter johnsonii strain Aj2199. These genes contribute to resistance against various antibiotics, highlighting the presence of horizontal genetic transfer in this strain.
