Retrospective descriptive study compares antimicrobial susceptibility profiles in Klebsiella spp. and other enterobacteria, suggesting significant resistance patterns.
Key Points
This research aims to compare the antimicrobial susceptibility profiles of Klebsiella spp. and other bacteria that produce the NDM enzyme.
Performed a retrospective descriptive analysis of medical records from a tertiary hospital for cases of NDM-producing microorganisms.
Gathered data on etiologic agents, antibiograms, and classification as infection or colonization.
Organized data into groups based on etiologic agents and analyzed with a chi-square test.
57 records of positive cultures identified, with 75.44% classified as infections and 24.56% as colonizations.
Klebsiella spp. represented 57.89% of the sample, notably Klebsiella pneumoniae.
87.72% susceptibility rate to amikacin; 96.49% resistance to beta-lactams; 78.95% resistance to carbapenems.
Klebsiella spp. showed greater resistance to quinolones compared to other bacteria (p = 0.03).
