Pediatric central nervous system infections in the Amazon: clinical and laboratory profiles.

Background: Central nervous system (CNS) infections are important causes of mortality and morbidity in children, and they are related to severe problems such as hearing loss, neurological sequelae, and death. The objective was to describe clinical and laboratory exam profiles of children who were diagnosed with CNS infections.

Methods: We conducted a cross-sectional study based on medical records, which included pediatric patients aged from 3 months to 15 years, with a clinical suspicion of CNS infection between January 2014 to December 2019.

High levels of gut carriage of antimicrobial-resistant Escherichia coli in community settings in Rio de Janeiro, Brazil.

The prevalence and risk factors for gut carriage of antimicrobial-resistant Escherichia coli among individuals living in the community in Rio de Janeiro, Brazil, are unknown. The aim of this study was to determine the prevalence of colonization with antimicrobial-resistant E. coli, including isolates producing ESBL and harboring plasmid-mediated quinolone resistant (PMQR) genes in this community.

OXA-181 carbapenemase carried on an IncX3 plasmid in high-risk Escherichia coli ST167 isolated from a traveler returning from Sub-Saharan Africa to Brazil.

This is the first detection and genomic analysis of an OXA-181-carbapenemase-producing E. coli in Brazil, from a traveler returning from Sub-Saharan Africa. The ST167 isolate carries bla inserted in an IncX3 plasmid.

Acquisition of antimicrobial resistance determinants in Enterobacterales by international travelers from a large urban setting in Brazil.

Background: Antimicrobial resistance is increased by international mobility. We present data about intestinal colonization of travelers departing from a middle-income country.

Methods: Travelers were recruited from 2015 to 2019, collected an anal stool specimen and answered a questionnaire before and after travel.
