Immunohistochemical characterization of mononuclear cells in delayed hypersensitivity reactions to Paracoccidiodes brasiliensis (paracoccidioidin test)
(Kluwer Academic Publ, 1993-10-01)
The density and distribution of T cells, T helper cells, macrophages and B cells at the site of skin tests with a cytoplasmic Paracoccidioides brasiliensis antigen (paracoccidioidin) was studied at 24 and 48 h post-challenge ...
TH1/TH2 balance in concomitant immediate and delayed-type hypersensitivity diseases
(Elsevier B.V., 2009-06-04)
In spite of the observation of mutual inhibitory properties of TH1 and TH2 CD4+ cells, a group of patients developed simultaneously immediate and delayed-type hypersensitivity reactions that are theoretically antagonistic. ...
DELAYED-TYPE HYPERSENSITIVITY RESPONSE IN AN ISOGENIC MURINE MODEL OF PARACOCCIDIOIDOMYCOSIS
(Kluwer Academic Publ, 1994-06-01)
The specific delayed-type hypersensitivity (DTH) response was evaluated in resistant (A/SN) and susceptible (B10.A) mice intraperitoneally infected with yeasts from a virulent (Pb18) or from a non-virulent (Pb265) ...

Delayed type hypersensitivity induced by intradermal inoculation of a Neospora caninum tachyzoite antigen in previously exposed cattle
(Elsevier Science, 2019-01)
The aim of this study was to evaluate delayed type hypersensitivity (DTH) induced by the intradermal inoculationof a Neospora caninum tachyzoite soluble lysate in cattle previously exposed with the protozoa. Fourexperimental ...
Skin hypersensitivity tests in buffaloes parasitized with Toxocara vitulorum.
(Elsevier B.V., 1996-06-01)
Skin tests were done using larval extract and excretory-secretory (ES) antigens injected intradermally in the neck area of 30, 11- to 200-day-old buffalo calves and nine 27- to 100-day postparturition buffalo cows, the ...
