| cat-scratch fever | <disease> A self-limiting bacterial infection of the regional lymph nodes (lymphadenitis) caused by afipia felis, a gram-negative bacterium recently identified as bartonella henselae. It usually arises one or more weeks following a feline scratch, with raised inflammatory nodules at the site of the scratch being the primary symptom. It results in tender and enlarged lymph glands above the site of injury. A chronic benign adenopathy, especially in children and young adults, commonly associated with a recent cat scratch or bite and caused by bacteria including Bartonella henselae and Alipia felis; the lymphadenopathy usually resolves spontaneously within a period of several months, but complications involving central nervous system, liver, spleen, lung, and skin have been seen. Synonym: benign inoculation lymphoreticulosis, benign inoculation reticulosis, cat-scratch fever, regional granulomatous lymphadenitis. (05 Mar 2000) |
