From Diarrhea to Bacteremia: Extended-Spectrum Beta-Lactamase (ESBL)-Producing Shigella in a Rare Clinical Scenario.

Though globally prevalent, infections rarely progress to bacteremia (shigellemia), particularly in immunocompetent individuals. Here, we report a case of shigellemia with extended-spectrum beta-lactamase (ESBL) in Qatar, involving a 53-year-old immunocompetent male with no significant medical history. The patient presented with a one-day history of frequent loose stools, fever, and mild central abdominal pain.
