First report of CrpP prevalence in a South American country.

The presence of was established in 201 isolates from 9 Peruvian hospitals. The 76.6% (154/201) of the isolates presented the gene.

Tolerance to disinfectants (chlorhexidine and isopropanol) and its association with antibiotic resistance in clinically-related isolates.

Disinfectants play an essential role in controlling the dissemination of bacteria in health care settings, but it may also contribute to the selection of antibiotic resistance bacteria. This study looked at isolates collected from three hospitals in Lima, Peru, in order to evaluate: their susceptibility to chlorhexidine [CHG] and isopropanol [ISP]), and their association with antimicrobial susceptibility. We analyzed 59  isolates and assessed their CHG and ISP susceptibility by minimum inhibitory concentrations (MICs).

Multidrug resistance bacteremia in neonates and its association with late-onset sepsis and Coagulase-negative Staphylococci.

Introduction: This study aimed to assess the association between multidrug resistance (MDR) and late-onset sepsis (LOS) among newborns with bloodstream infection (BSI).

Methodology: In this cross-sectional study, we routinely tested every newborn with a presumptive diagnosis of sepsis admitted to the largest reference maternity hospital in Lima, Peru for BSI over an 18-month period. We tested every isolate for MDR by using the disk-diffusion method and assessed its associated factors by using a robust Poisson regression analysis with a particular focus on its association with LOS (vs.
