Prevalence of Fecal Carriage of CTX-M-15 Beta-Lactamase-Producing in Healthy Children from a Rural Andean Village in Venezuela.

Objectives: Antimicrobial resistant extended-spectrum-β-lactamase-producing (ESBL-PE) have been shown to be present in healthy communities. This study examined healthy children from the rural Andean village of Llano del Hato, Mérida, Venezuela, who have had little or no antibiotic exposure to determine the prevalence of fecal carriage of ESBL-producing (ESBL-EC).

Methods: A total of 78 fecal samples were collected in healthy children aged from 1 to 5 years.

[Clinical and microbiological study of catheter-associated urinary tract infections in internal medicine services of a Venezuelan university hospital].

Objectives: To determine the clinical and microbiological characteristics of catheter-associated urinary tract infections (CA-UTI) in patients admitted to the Internal Medicine services of the Hospital Universitario de Los Andes (HULA), Mérida, Venezuela and to establish the clonal distribution of multi-resistant Enterobacteriaceae that produce this infection.

Materials And Methods: Seventy-three adult patients with bladder catheterization were studied between January and July 2015. The microbiological processing of the urine samples was performed using conventional and automatized methods.

Nosocomial outbreak of extended-spectrum β-lactamase-producing Enterobacter ludwigii co-harbouring CTX-M-8, SHV-12 and TEM-15 in a neonatal intensive care unit in Venezuela.

Enterobacter spp. have emerged as an important group of pathogens linked to outbreaks in neonatal intensive care units (NICUs), usually involving strains expressing extended-spectrum β-lactamases (ESBLs). The aim of this study was to describe the first nosocomial bloodstream infection outbreak caused by Enterobacter ludwigii co-harbouring CTX-M-8, SHV-12 and TEM-15 in a NICU in a Venezuelan hospital.

First Description of KPC-2-Producing Klebsiella oxytoca Isolated from a Pediatric Patient with Nosocomial Pneumonia in Venezuela.

During the last decade, carbapenem resistance has emerged among clinical isolates of the Enterobacteriaceae family. This has been increasingly attributed to the production of β-lactamases capable of hydrolyzing carbapenems. Among these enzymes, Klebsiella pneumoniae carbapenemases (KPCs) are the most frequently and clinically significant class-A carbapenemases.
