Antimicrobial Resistance Trends at a Pediatric Hospital in Guatemala City, 2005-2019.

Antimicrobial resistance (AMR) is increasing worldwide. We analyzed AMR rates for bacterial species identified from pediatric blood cultures between 2005 and 2019 at a single institution in Guatemala. We found significantly increased rates in Gram-negative resistance, with a high prevalence of carbapenem-resistant Acinetobacter and Klebsiella harboring the New Delhi metallo-beta-lactamase gene.
