Molecular Characterization of Extended-Spectrum β-Lactamase-Producer Klebsiella pneumoniae Isolates Causing Neonatal Sepsis in Peru.

ABSTRACT: Klebsiella pneumoniae (KP) is the most common cause of neonatal sepsis in the low- and middle-income countries. Our objective was to describe the phenotypic and molecular characteristics of extended-spectrum β-lactamase (ESBL)-producer KP in neonatal care centers from Peru. We collected 176 non-duplicate consecutive KP isolates from blood isolates of neonates from eight general public hospitals of Lima, Peru. The overall rate of ESBL production was 73.3% (N = 129). The resistance rates were higher among ESBL-producer isolates when compared with the nonproducers: 85.3% versus 12.8% for gentamicin (P < 0.01), 59.7% versus 8.5% for trimethoprim-sulfamethoxazole (P < 0.01), 45.0% versus 8.5% for ciprofloxacin (P < 0.01), and 36.4% versus 12.8% for amikacin (P < 0.01). A total of 359 β-lactamas
