Induction of the delayed footpad and wattle reaction to killed Staphylococcus aureus in chickens.
Two experiments were conducted to induce the delayed footpad reaction (DFR) to killed Staphylococcus aureus antigen. In Experiment 1, tracheal, cloacal, and choanal swabs were collected from chickens prior to sensitization with S. aureus to determine the carrier status of S. aureus. The second experiment compared the DFR to the delayed wattle reaction (DWR). Chickens were subjected to single or...
متن کاملPassive transfer of delayed-type hypersensitivity to cell walls of Staphylococcus aureus.
Protracted inflammatory dermal reactions to staphylococcal cell walls were observed in guinea pigs passively sensitized by transfer of peritoneal exudate cells but not by immune serum from guinea pigs actively sensitized with heat-killed cells of Staphylococcus aureus. The experiments verify the hypothesis that the protracted reaction is a cell-mediated immune response which is resolvable from ...
متن کاملVirus-induced delayed-type hypersensitivity reaction is sequentially mediated by CD8+ and CD4+ T lymphocytes.
After subcutaneous inoculation into the hind foot of a mouse, the lymphocytic choriomeningitis (LCM) virus multiplies locally, attaining 10(7)-10(8) mouse infectious units per g of tissue; elimination commences around day 7. About 1 day earlier, the foot begins to swell, which is regarded as a delayed-type hypersensitivity (DTH) reaction. To answer the question of whether the local inflammatory...
متن کاملRole of IL-16 in delayed-type hypersensitivity reaction.
Interleukin (IL)-16 is a chemoattractant cytokine for CD4(+) leukocytes. Because delayed-type hypersensitivity (DTH) reaction is mediated by T helper 1 (Th1) cells and CD4(+) T cells can be chemoattracted by IL-16, we have investigated the involvement of IL-16 in the DTH reaction. Immunohistochemical analysis revealed the IL-16 expression in infiltrating cells and epithelial cells in the DTH fo...
متن کاملPrevalence of clindamycin-resistant Staphylococcus aureus induced by macrolide resistance
Introduction: Since the incidence of various infections caused by Staphylococcus aureus increases, the use of effective antibiotics such as clindamycin has been growing to treat the systemic and local infections caused by such organisms. Antibiotic-resistant species are emerging and spreading in today's communities due to misuse of antibiotics and incomplete treatment, turning into a serious ch...
