Caracterización de la resistencia a tetraciclina en Salmonella Typhimurium proveniente de aislamientos clínicos colombianos

Abstract

Nontyphoidal salmonella (NTS) is one of the major causes of bacterial diseases transmitted by food worldwide (1). In addition, these bacteria are on the WHO priority list due to the development and dispersion of multiresistance to antibiotics (2). Among them, the incidence of tetracycline resistance was documented in the international outbreak of Salmonella Typhimurium infections occurred between 2008 and 2010 in the United States, the United Kingdom and Canada (3). In Colombia, the national surveillance of Acute Diarrheal Disease performed by the Microbiology Group of the Instituto Nacional de Salud confirmed that 77.7% (n=2167) of the clinical isolates of S. Typhimurium recovered from 1997 to 2016 are resistant to tetracycline.
