Pyogenic Hepatic Abscess and Septic Pulmonary Emboli Associated WithKlebsiella ozaenaeBacteremia

摘要

KLEBSIELLA OZAENAEis a nonmotile, aerobic, encapsulated, gram-negative rod named for its association with ozena, a chronic atrophic rhinitis, even though its etiologic role in this condition is conjectural. Its significance as a human pathogen is unclear, though it has been increasingly implicated as a low virulence opportunist.K ozaenaeis a rare isolate in cases of bacteremia and soft tissue or urinary tract infections,Klebsiella pneumomiaebeing more than a hundredfold more commonly identified. When identified, the majority ofK ozaenaeisolates have been from the respiratory tract and considered colonizers.We report the first published case of community acquired cryptogenic hepatic abscess with pulmonary emboli associated withK ozaenaebacteremia in a previously healthy patient. We then review the literature on the organism's role as a human pathogen.
