Serratia marcescens antibiotic resistance mechanisms of an opportunistic pathogen: a literature review.

is a ubiquitous bacterium from order displaying a high genetic plasticity that allows it to adapt and persist in multiple niches including soil, water, plants, and nosocomial environments. Recently, has gained attention as an emerging pathogen worldwide, provoking infections and outbreaks in debilitated individuals, particularly newborns and patients in intensive care units. isolates recovered from clinical settings are frequently described as multidrug resistant. High levels of antibiotic resistance across species are a consequence of the combined activity of intrinsic, acquired, and adaptive resistance elements. In this review, we will discuss recent advances in the understanding of mechanisms guiding resistance in this opportunistic pathogen.
