Cell-mediated immunity in experimental Nocardia asteroides infection.
Experimental mycetoma-like lesions developed in guinea pigs after subcutaneous injection of Nocardia asteroides. Although delayed hypersensitivity appeared earlier, increased macrophage migration inhibition and microbicidal activity appeared after 7 weeks. When the lesions healed, high cell-mediated immunity was present. Cell-mediated immunity was transferred to normal recipient guinea pigs fro...
متن کاملRelationship of macrophages to cell-mediated immunity in experimental Nocardia asteroides infection.
Marked in vivo intracellular killing of Nocardia asteroides occurred in the peritoneal macrophages obtained 72 h after an intraperitoneal challenge with N. asteroides, in guinea pigs either actively immunized with ribonucleic acid protein or passively immunized by immune spleen cell transfer from actively immunized donor guinea pigs. This specific killing of N. asteroides in immune macrophages ...
متن کاملNocardia asteroides ocular infection
Methods The ocular samples viz., corneal swab, corneal scraping, aqueous tap and vitreous tap were processed for culture and the isolated Nocardia species were further confirmed for speciation by standard microbiological procedures. Antibiotic susceptibility analysis for the confirmed isolates of N. asteroides was performed by agar disk diffusion method following the guidelines of Clinical Labo...
متن کاملNocardia asteroides osteomyelitis.
Nocardia asteroides osteomyelitis has previously been described only in acutely ill patients. It may occur as an isolated event or part of the disease spectrum of disseminated nocardiosis. An 84 year old immune competent man with N. asteroides right tibial osteomyelitis had an unusual presentation, presumed mechanism of disease and outcome. His course affords an opportunity to review the litera...
متن کامل[Nocardia asteroides keratitis].
Problems in management of ulcerative keratitis may arise from delays in diagnosis and from inadequate response to treatment. In the present case, a corneal injury was followed by Nocardia asteroides keratitis. The organism isolated was sensitive in vitro to both sulphonamides and penicillin, but there was no satisfactory clinical improvement with sulphonamides alone. Good response to treatment ...
