title: Hepatobiliary infections caused by Haemophilus species.
abstract: Haemophilus species are rarely associated with hepatobiliary infections. We report a case of hepatic abscess caused by Haemophilus paraphrophilus and review the English-language literature for reports of infections of the liver and biliary system caused by Haemophilus species. Most patients identified had predisposing conditions. The pathogenesis of hepatobiliary infections due to Haemophilus species may involve ascending spread from the gastrointestinal tract or hematogenous seeding following oropharyngeal colonization.
