What causes E. coli bacteremia?

Third, urinary tract infection (UTI) is the leading source for E. coli bacteremia, accounting for more than 50% of cases. The risk of UTI increases with age due to physiological changes that lead to bladder dysfunction and urinary catheter use, which increase the risk of bacterial colonization and infection.

How is E. coli bacteremia treated?

E coli meningitis requires antibiotics, such as third-generation cephalosporins (eg, ceftriaxone). E coli pneumonia requires respiratory support, adequate oxygenation, and antibiotics, such as third-generation cephalosporins or fluoroquinolones.

What happens if E. coli gets in your bloodstream?

The presence of E. coli in the bloodstream can result in the induction of a vigorous host inflammatory response that lead to sepsis, which is associated with high morbidity and mortality (Russo and Johnson, 2003; Miajlovic and Smith, 2014). In addition, the rates of multidrug resistant (MDR) E.
