Detection of carbapenemases in Enterobacterales susceptible in vitro to meropenem.
Enferm Infecc Microbiol Clin (Engl Ed)
January 2025
Introduction: Carbapenemase-producing Enterobacterales (CPE) is a global threat. We evaluate the prevalence of CPE among isolates categorized as meropenem-susceptible, but that meet the European Committee on Antimicrobial Susceptibility Testing (EUCAST) screening cut-off values for carbapenemase detection, and analyze the susceptibility of these isolates to new available drugs.
Methods: We analyzed 257 isolates from patients hospitalized in a tertiary hospital in Brazil, from July 2022 to April 2023.
Nasopharyngeal transmission of Streptococcus pneumoniae is a prerequisite for the development of pneumococcal diseases. Previous studies have reported a relationship between respiratory viruses and S. pneumoniae infections.

The aim of the study was to describe an outbreak of carbapenem-resistant A seifertii among neonates admitted to the neonatal intensive care unit (NICU) at a tertiary care hospital.
Methods: All patients with carbapenem-resistant A seifertii diagnosed and admitted to the NICU from June 2023 to October 2023 were included.
Iquitos Virus in Traveler Returning to the United States from Ecuador.
Emerg Infect Dis
November 2024
Article Synopsis
- A traveler returning to the U.S. from Ecuador experienced an acute fever and was initially thought to have Oropouche fever.
- Further testing revealed that the illness was actually due to a rare infection with Iquitos virus, which is related to Oropouche virus.
- Iquitos virus shares two out of three genome segments with Oropouche virus, highlighting the complexity of diagnosing such infections.
Rapid colorimetric polymyxin B microelution directly from positive blood bottles: because patients with serious infections should not have to wait for results of culture-based methodologies.
Eur J Clin Microbiol Infect Dis
July 2024
Purpose: To evaluate the performance of the rapid colorimetric polymyxin B microelution (RCPEm) in determining polymyxin B resistance directly from Enterobacterales-positive blood cultures.
Methods: A set volume of positive blood culture bottles (diluted 1:10) was inoculated into a glucose-broth-phenol red solution (NP solution), where a polymyxin B disk was previously eluted (final concentration of 3 µg/mL). Test was read each 1 h for up to 4 h.
