Molecular Epidemiology of <i>Escherichia coli</i> Clinical Isolates from Central Panama
<i>Escherichia coli</i> represents one of the most common causes of community-onset and nosocomial infections. Strains carrying extended spectrum β-lactamases (ESBL) are a serious public health problem. In Central America we have not found studies reporting the molecular epidemiology of...

<i>Escherichia coli</i> represents one of the most common causes of community-onset and nosocomial infections. Strains carrying extended spectrum β-lactamases (ESBL) are a serious public health problem. In Central America we have not found studies reporting the molecular epidemiology of <i>E. coli</i> strains implicated in local infections, so we conducted this study to fill that gap. <i>Materials and Methods:</i> We report on an epidemiological study in two reference hospitals from central Panama, identifying the susceptibility profile, associated risk factors, and molecular typing of <i>E. coli</i> strains isolated between November 2018 and November 2019 using Pasteur’s Multilocus Sequence Typing (MLST) scheme. <i>Results:</i> A total of 30 <i>E. coli</i> isolates with antimicrobial resistance were analyzed, 70% of which came from inpatients and 30% from outpatients (<i>p</i> < 0.001).
