Association of a major protein antigen of Mycoplasma arthritidis with virulence.

abstract：:The role of the hypothalamus-pituitary-adrenal (HPA) axis in regulating the growth of Mycobacterium avium in Mycobacterium bovis BCG-resistant and -susceptible congenic mice was evaluated. Restraint was used to activate the HPA axis, which resulted in an increase in the level of corticosterone in the plasma. Activatio...
