Neutrophilic cholangitis/cholangiohepatitis results from ascending bacterial infection from the small intestines.  [[Escherichia coli]], [[Staphylococcus spp.]], ''Streptococcus spp.'', ''Clostridium spp.'', ''Bacillus spp.'', ''Actinomyces spp.'', ''Bacteroides spp.'' and occasionally ''Salmonella spp.'' have been isolated.  Concurrent biliary tract disease are common in cats, especially pancreatitis and inflammatory bowel disease.  Other predisposing factors include bile duct obstruction, cholelithiasis, cholecystitis.

Neutrophilic cholangiohepatitis is characterised by infiltration of large numbers of neutrophils into portal areas of the liver and into the bile ducts.  It results from ascending bacterial infection from the small intestines.  [[Escherichia coli]], [[Staphylococcus spp.]], ''Streptococcus spp.'', ''Clostridium spp.'', ''Bacillus spp.'', ''Actinomyces spp.'', ''Bacteroides spp.'' and occasionally ''Salmonella spp.'' have been isolated.  Concurrent biliary tract disease are common in cats, especially pancreatitis and inflammatory bowel disease.  Other predisposing factors include congenital or acquired abnormalities of the biliary system such as that of anatomic abnormalities of the gall bladder or common bile duct, bile duct obstruction caused by inspissated bile, cholelithiasis and cholecystitis.
