Abstract
Extra intestinal Pathogenic Escherichia coli (ExPEC) is a leading cause of invasive infections. These include entities like bacteremia, respiratory tract infections, meningitis and sepsis among others. Invasive ExPEC infection complicates the clinical treatment of other conditions. It is also associated with increased mortality, duration of hospital stay, and worse clinical outcomes. Older adults having comorbidities are at highest risk of acquiring these infections. ExPEC is of particular interest in the AsiaPacific region, due to aging populations and increasing antimicrobial resistance.
