Stimulation of immunoglobulin-containing cells and isotype-specific antibody response in experimental Mycoplasma hyopneumoniae infection in specific-pathogen-free pigs.

abstract：:An exoprotein of Staphylococcus aureus 100 that elicited a positive ileal loop response in the rabbit model was investigated in this study. The protein, as it occurred in the culture supernatant fluid, could be detected initially in the late log phase of growth under aerobic and anaerobic conditions. It was stable und...
