title: [Hypersensitivity in patients with Hebra's prurigo caused by flea bite].
abstract: The authors present a study of hypersensitivity of patients with Hebra's prurigo (HP) to feleabites. Thirty six patients were studied. With the results obtained the following conclusions are held: 1. Among the probable responsible factors found in the history of patients with HP, the flea bite is the principal factor. 2. Almost all the patients with HP who were studied show hypersensitivity to flea bites. 3. With the flea bites on the patients with HP, one can observe the clinical and histopathology similarity of both the experimental and elementary lesions of the disease. 4. It was possible to show humoral antibodies in the serum of the patients with HP immunodiffusion technique to the 1:40 flea extract.
