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.

Colistin resistance in multidrug-resistant Klebsiella pneumoniae strains at a perinatal maternal institute in Lima, Peru, 2015-2018.

The objective of this study was to evaluate the presence of colistin- and carbapenemic-resistant genes in multidrug-resistant Klebsiella pneumoniae strains isolated at the Instituto Materno Perinatal de Lima (2015-2018). Susceptibility levels were analyzed by disk diffusion and microdilution. The presence of colistin- and carbapenemic-resistant genes was determined by polymerase chain reaction (PCR) and was related to clonality.

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 and its association with Enterobacteriales and age among pregnant Peruvian women with- bacteremia.

Introduction: This study aimed to assess the prevalence of multidrug resistance (MDR) and its associated factors among pregnant Peruvian women with bacteremia.

Methodology: In an 18-month cross-sectional study, all pregnant women were routinely tested with a presumptive diagnosis of sepsis admitted to the largest reference maternity hospital (Instituto Nacional Materno Perinatal) in Lima, Peru for bacteremia. Every isolate was tested for antimicrobial susceptibility as defined by the Institute of Clinical and Laboratory Standards (CLSI).

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.

Disseminated cutaneous histoplasmosis in newly diagnosed HIV.

We present a woman with a widespread severe papulopustular eruption, fever, and fatigue of 5 weeks' duration. HIV infection was diagnosed, with an absolute CD4(+) count of 3 cells/µL. The eruption was consistent with disseminated cutaneous histoplasmosis.

Acral vesicles and bullae in a patient with severe rheumatoid arthritis.

We present the case of a 56-year-old black woman with rheumatoid arthritis who developed worsening fatigue, fever, weight loss, and a vesiculobullous skin eruption while being treated with certolizumab pegol for her arthritis. Microscopic findings confirmed the diagnosis of a neutrophilic dermatosis.
