Molecular Analyses of Biofilm-Producing Clinical Acinetobacter baumannii Isolates from a South Indian Tertiary Care Hospital.

Objectives: The aim of the study was to determine the presence of antimicrobial-resistance (AMR) genes, virulence genes, and mobile genetic elements (MGEs) in 14 biofilm-producing clinical isolates of Acinetobacter baumannii.

Materials And Methods: PCR amplification was performed to analyse the prevalence of genes associated with antibiotic resistance (extended-spectrum β-lactamases [ESBLs] and metallo-β-lactamases [MBLs]), virulence factors, MGEs (class 1 integron, Tn1213, and A. baumannii antibiotic resistance [AbaR]), and comM among the study isolates.
