[Benign inoculation lymphoreticulosis or cat-scratch disease]

Discovered in 1950-51 by two great parisian medical teams, inoculation lymphoreticulosis, also called cat's scratch disease, is locoregional adenitis whose aetiology is imperfectly determined. Following, often bu not always, cat's scratch, it may evolve to suppuration. Pus is always aseptic. Attributed to Bedsonia's family micro-organism, no cultivation was possible up to date. Evolution is as a rule favourable, but disease is poorly accessible to tetracycline family's antibiotics. Diagnosis is possible by intradermoreaction. The antigen used is tyndallised pus of homologous infection. The role of the cat, still healthy, has not yet been explained.
