Molecular Characterization of Obtained from Blood Cultures of Paediatric Patients Treated in a Tertiary Care Hospital in Mexico.

Purpose: is one of the main causative agents of hospital-acquired (HA) infections. In Mexico, information about the characteristics of clinical isolates is limited. Our aim was to characterize strains obtained from blood cultures of paediatric patients treated in a tertiary care hospital.

Nosocomial, Multidrug-Resistant Klebsiella pneumoniae Strains Isolated from Mexico City Produce Robust Biofilms on Abiotic Surfaces but Not on Human Lung Cells.

Background: Klebsiella pneumoniae (Kpn) strains are a leading cause of hospital-acquired infections, including ventilator-associated pneumonia. Resistance to antibiotics, biofilm formation, and the production of certain fimbriae play an important role in the pathogenesis.

Aim: We investigated the genetic relatedness, antibiotic resistance, virulence potential, and ability to form biofilms of Kpn strains isolated from hospital-acquired infections (n = 76).
