During 2020-2021, countries in Latin America and the Caribbean reported clinical emergence of carbapenemase-producing Enterobacterales that had not been previously characterized locally, increased prevalence carbapenemases detected, co-production multiple some isolates. These increases were likely fueled by changes related to COVID-19 pandemic, including empirical antibiotic use for potential COVID-19-related bacterial infections healthcare limitations resulting from rapid rise cases....

ABSTRACT Polymyxins are last-resort antimicrobial agents used to treat infections caused by carbapenem-resistant Enterobacteriaceae . Due the worldwide dissemination of polymyxin resistance in animal and human isolates, we aimed characterize associated with presence mcr-1 nonfermenter Gram-negative bacilli, using isolates collected retrospectively Colombia from 2002 2016. A total 5,887 clinical were studied, 513 found be resistant polymyxins. Susceptibility colistin was confirmed broth...

In 1998, the Colombian government initiated an immunization program for children under one year of age with a Haemophilus influenzae capsular type b conjugate vaccine. After two years, surveillance Instituto Nacional de Salud Microbiology Group reported 40% decrease in meningitis cases caused by H. influenzae. This effect was attributed to vaccination. The uses standardized slide agglutination technique serotype current study validated accuracy method means PCR technique. From five years...
