HAL: Hospital Arzobispo Loayza, HNCH: Hospital Nacional Cayetano Heredia. New alleles and new sequence types described in this study are highlighted in bold. (−) negative phenotype. PS: Pan-susceptible; MR: Moderately drug-resistant; MDR: Multi drug-resistant. XDR: Extensively drug-resistant. XDR*: isolates resistant to all the antimicrobial agents tested except colistin. (1) wound/abscesses, (2) urine, (3) bronchial secretion, (4) catheter, (5) sputum.
