The principal surveillance tool used to control bovine tuberculosis in cattle is the removal of animals that provide a positive response to the tuberculin skin-test. In this study we performed a longitudinal investigation of the immunological and diagnostic consequences of repeated short-interval skin-tests in cattle naturally infected with Mycobacterium bovis. Tuberculin skin-test positive cat...

hypersensitivity reactions to natural rubber latex have increased recently, especially among people with high exposure to latex allergens. hypersensitivity reactions to latex are related to many conditions like occupational asthma. our study was performed to determine the prevalence of hypersensitivity to natural rubber latex and potential food cross reactions in operation room personnel in shi...

Hypersensitivity responses to two highly purified and well characterized mycobacterial proteins and a preparation of mycobacterial arabinogalactanarabinomannan were studied by using guinea pig skin tests and in vitro-cultured human lymphocyte mitogenesis stimulation assays. The purified proteins were found to elicit delayed-type hypersensitivity skin test reactions and to stimulate mitogenesis ...

BACKGROUND Ipe is a resistant hardwood that contains naphtoquinones. It is easily found and frequently used in South and Central America. Naphtoquinones are skin sensitizers. OBJECTIVE To describe a case of occupational asthma related to Ipe wood dust. METHODS The patient was submitted to a clinical evaluation consisting of a respiratory symptom questionnaire, occupational history, serial m...

objective: the prevalence of respiratory allergies, especially those induced by fungi such as alternaria alternata, has dramatically increased over the past decade. this increase has caused major health problems worldwide. this study aimed to investigate the role of a. alternata in the etiology of allergic asthma, by using the skin prick test and assessment of ige specific to the fungus in the ...

A rapid reversed passive latex agglutination method that uses high-density latex particles for the detection of staphylococcal enterotoxins (SE) A to E was developed. It took 3 h for incubation, much less than the 16 h needed with a customary latex agglutination test for SE detection such as a commercial test kit (SET-RPLA; Denka Seiken Co. Ltd., Tokyo, Japan). The rapid test was shown to be hi...

Nine cases of diclofenac hypersensitivity recorded by the Allergy Vigilance Network in France from 2002 to 2012 were studied. Data from history, symptoms, skin tests, basophil activation tests, and oral challenge (OC) were recorded. Grade 3 severe anaphylactic reactions occurred in seven cases of nine. IgE-dependent anaphylaxis was confirmed in six cases: positive intradermal tests (n = 4), a s...

Material and method A prospective study was performed using ENDA questionnaire in 103 children [4.8 (2.7-7.9) years, 60% male] with 124 non-immediate type hypersensitivity reactions. Prick and intradermal skin testing with major/minor determinant mixture, penicilin G, ampicillin, amoxicillinclavulanate and the culprit drug were done. In patients with negative skin tests, patch and intradermal t...
