Aerobic gram-negative bacteremia

Aerobic gram-negative bacteremia is a systemic bloodstream infection characterized by the presence of viable aerobic or facultatively anaerobic gram-negative bacteria circulating in the vascular system It most commonly originates from primary focus sites such as the urinary tract, gastrointestinal tract, lungs, or intravascular catheters, predominantly affecting hospitalized, elderly, and immunocompromised individuals Clinically, it manifests along a continuum from fever, rigors, and tachycardia...

Aerobic gram-negative bacteremia is a systemic bloodstream infection characterized by the presence of viable aerobic or facultatively anaerobic gram-negative bacteria circulating in the vascular system Clinically, it manifests along a continuum from fever, rigors, and tachycardia to severe sepsis, septic shock, and multiple organ dysfunction

It most commonly originates from primary focus sites such as the urinary tract, gastrointestinal tract, lungs, or intravascular catheters, predominantly affecting hospitalized, elderly, and immunocompromised individuals

It most commonly originates from primary focus sites such as the urinary tract, gastrointestinal tract, lungs, or intravascular catheters, predominantly affecting hospitalized, elderly, and immunocompromised individuals Pathophysiologically, the condition is driven by the shedding of bacterial outer membrane lipopolysaccharide (endotoxin), which triggers intense host cytokine release, widespread endothelial damage, and microvascular hypoperfusion
