| Summary: | Antimicrobial-resistant pathogenic bacteria are an increasing problem in public health, especially in the healthcare environment, where nosocomial infection microorganisms find their niche. Among these bacteria, the genus <i>Acinetobacter</i> which belongs to the ESKAPE pathogenic group harbors different multi-drug resistant (MDR) species that cause human nosocomial infections. Although <i>A. baumannii</i> has always attracted more interest, the close-related species <i>A. pittii</i> is the object of more study due to the increase in its isolation and MDR strains. In this work, we present the genomic analysis of five clinically isolated <i>A. pittii</i> strains from a Spanish hospital, with special attention to their genetic resistance determinants and plasmid structures. All the strains harbored different genes related to β-lactam resistance, as well as different MDR efflux pumps. We also found and described, for the first time in this species, point mutations that seem linked with colistin resistance, which highlights the relevance of this comparative analysis among the pathogenic species isolates. |
