Multidrug-resistant <i>Pseudomonas aeruginosa</i> and its coexistence with β-lactamases at a tertiary care hospital in a low-resource setting: a cross-sectional study with an association of risk factors

Identification of XDR-PA and β-lactamases among MDR-PA isolates is crucial to prevent the use of unnecessary antibiotics. Early and prompt diagnosis of drug-resistant pathogens prevents treatment failure and encourages proper antibiotic therapy. Therefore, it is necessary to implement strict policies on the use of antibiotics without proper diagnosis.
