E. coli is a Gram-negative (bacteria which do not retain crystal violet dye), facultative anaerobic (that makes ATP by aerobic respiration if oxygen is present, but is capable of switching to fermentation or anaerobic respiration if oxygen is absent) and nonsporulating bacterium.
Abscesses are often polymicrobial, and E coli is one of the more common gram-negative bacilli observed together with anaerobes. Cholecystitis and cholangitis result from obstruction of the biliary system from biliary stone or sludge, leading to stagnation and bacterial growth from the papilla or portal circulation.
