Methicillin-Resistant Staphylococcus aureus Bloodstream Infections in Hospitalized Patients in Peru.

There is a knowledge gap in the epidemiology of methicillin-resistant Staphylococcus aureus (MRSA) causing bloodstream infections (BSIs) in Peru. Through a surveillance study in 13 hospitals of 10 Peruvian regions (2017-2019), we assessed the proportion of MRSA among S. aureus BSIs as well as the molecular typing of the isolates.

Microbiological and molecular characterization of antimicrobial resistance in uropathogenic Escherichia coli from peruvian public hospitals.

We characterized the antimicrobial resistance of 70 Escherichia coli isolates obtained from patients with a urinary tract infection (UTI) from 8 public hospitals in Peru. Resistance profiles were identified using the automated MicroScan® system. A standard polymerase chain reaction was used for the detection of the bla TEM, bla CTX-M, bla SHV and bla PER genes.

The Prevalence of Rheumatoid Arthritis in Chile: A Nationwide Study Performed as Part of the National Health Survey.

Objective: Genetic and environmental backgrounds influence the development of rheumatoid arthritis (RA). In Latin America, epidemiologic data are scarce. We aimed to determine the prevalence of RA in Chile in a population-based study.
