often colonizes the gut asymptomatically, KLAs develop when hvKp disseminates from the gut to the liver via the portal vein. Strains expressing K1 and K2 capsule types demonstrate the highest resistance to clearance by Kupffer cells, the liver resident macrophages, and are responsible for most KLA cases. KLAs present as fibrously encapsulated lesions composed of bacteria, pus, and immune cells. Treatment typically involves a combination of abscess drainage and antibiotic therapy; however, clinical outcomes are often poor, even in the absence of antibiotic resistance. This is due, in part, to significant barriers to achieving effective antibiotic efficacy within abscesses that can result in devastating complications such as metastatic infection, liver resection, or death.
