Nosocomial Pneumonia in Georgia: A Study of Extended Spectrum Beta-Lactamase (ESBL)-Producing Versus Non-extended ESBL Gram-Negative Bacterial Profiles.

Background: Nosocomial pneumonia is a significant healthcare challenge, particularly in the face of rising antimicrobial resistance among Gram-negative bacteria. The production of extended spectrum beta-lactamase (ESBL) exacerbates treatment complexities.

Aim: This study investigates the prevalence and resistance patterns of ESBL-producing and non-ESBL Gram-negative bacteria in nosocomial pneumonia cases in Georgian hospitals to inform antibiotic stewardship and treatment strategies.
