It employs a range of virulence factors to invade ocular tissues, leading to complications such as corneal scarring and perforation. Alarmingly, multidrug-resistant &lt;em&gt;P. aeruginosa&lt;/em&gt; isolates are increasing worldwide. For instance, a recent outbreak in the United States of America (USA) involving an extensively drug-resistant &lt;em&gt;P. aeruginosa&lt;/em&gt; PA1270 strain resulted in four deaths, four eye removals, and 14 cases of vision loss. A comprehensive understanding of the antibiotic resistance and virulence mechanisms of &lt;em&gt;P. aeruginosa&lt;/em&gt; is essential for the effective management of corneal infections.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Methods&lt;/h3&gt;&lt;div&gt;Whole-genome sequencing data from 70 &lt;em&gt;P. aeruginosa&lt;/em&gt; isolates collected from corneal samples were retrieved from the National Center for Biotechnology Information (NCBI) database and annotated using Prokka 1.14.6. Unique genes identified in these datasets were analyzed against the Comprehensive Antibiotic Resistance Database (CARD) to determine antimicrobial resistance profiles. The presence of acquired resistance genes and virulence factors were assessed using ResFinder and the Virulence Factor Database (VFDB), respectively. Roary v3.13.0 was used for pangenome analysis, while Snippy v4.6.0 was employed for whole-genome variant analysis. Furthermore, mobile genetic elements (MGEs) and pathogenicity islands (PIs) were identified using MobileElementFinder v1.0.3 and IslandViewer 4, respectively. In parallel, phenotypic characterization, including determination of minimum inhibitory concentrations (MICs) for selected antimicrobial agents, was performed using the broth microdilution method.
