Métodos de identificación bacteriana para la determinación del agente causal de infección estafilocócica.

Abstract

The prevalence of nosocomial infections by opportunistic bacteria is a major public health problem. In 2018, Ecuador reported a rate of 2.4/1000 nosocomial bloodstream infections associated with the use of catheters, these devices favor infections of a number of opportunistic microorganisms, including staphylococci, with a significant predominance of coagulase-negative Staphylococcus. One of the most common species of coagulase-negative Staphylococcus related to nosocomial infections due to the use of medical devices is S. epidermidis, which is part of the human microbiota and becomes the main opportunistic pathogen, having the ability to form biofilms; this being its main mechanism of pathogenicity, in addition to a diversity of genes related to both antibiotic resistance and virulence developed within the infected host. For this reason, it is important to analyze a practical case by means of a bibliographic review for the determination of the causal agent in a staphylococcal infection.
