Nosocomial Pneumonia in Georgia: A Focus on Gram-Positive Bacteria and Antimicrobial Resistance.

Nosocomial pneumonia represents a significant clinical challenge worldwide, and in Georgia, the burden of this healthcare-associated infection is a growing concern. This study investigates the role of gram-positive bacteria in nosocomial pneumonia cases, focusing on their prevalence, antimicrobial resistance patterns, and associated risk factors. A retrospective analysis of 484 clinical samples collected from 397 patients between May 2022 and September 2024 highlights the distribution of pathogens, with a particular emphasis on and .

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.
