Cat Scratch Disease -- From Feline Affection to Human Infection

Abstract
Although cat scratch disease was first recognized more than 60 years ago, only in the past few years has real progress been made in identifying the microbes that cause this disorder. The diagnosis of cat scratch disease has relied on several criteria: a compatible clinical picture, usually with unilateral regional lymphadenitis; a history of contact with a cat, often followed by the formation of a papule at the site of primary inoculation; the exclusion of other identifiable causes, especially mycobacterial; the presence in a lymph-node biopsy specimen of multiple microabscesses or granulomas; and a positive response to a noncommercial skin . . .
