An epidemiological and molecular study regarding the spread of vancomycin-resistant Enterococcus faecium in a teaching hospital in Bogotá, Colombia 2016.

Background: Enterococcus faecium is ranked worldwide as one of the top ten pathogens identified in healthcare-associated infections (HAI) and is classified as one of the high priority pathogens for research and development of new antibiotics worldwide. Due to molecular biology techniques' higher costs, the approach for identifying and controlling infectious diseases in developing countries has been based on clinical and epidemiological perspectives. Nevertheless, after an abrupt vancomycin-resistant Enterococcus faecium dissemination in the Méderi teaching hospital, ending up in an outbreak, further measures needed to be taken into consideration.

[Antimicrobial susceptibility profile in urinary pathogens causing community-acquired infections in diabetic patients in Colombia].

Introduction: Urinary tract infection is the most common pathology in diabetic patients, and an important determinant of morbidity and mortality among them. The increasing resistance of uropathogens acquired in the community to commonly used antibiotics is alarming.

Objective: To identify the profile of antibiotic susceptibility of uropathogens responsible for communityacquired infections among diabetic patients in hospitals in Colombia.

Emergence of Providencia rettgeri NDM-1 in two departments of Colombia, 2012-2013.

Introduction: In Colombia, between 2012 and 2013, 19 isolates with NDM were identified, of which 14 corresponded to Providencia rettgeri.

Methods: The isolates were identified by Vitek-2, and antimicrobial susceptibility was evaluated by broth microdilution. The carbapenemase phenotypes were determined with Modified Hodge Test and synergy tests with EDTA/SMA and APB, the genotypes by PCR using specific primers for KPC, GES, IMP, VIM, OXA-48 and NDM, and genetic relationships were established with DiversiLab.
