| Outline of Final Research Achievements |
Mycoplasma bovis infectious disease in cattle is considered to be opportunistic infection, but the number of the outbreak increases remarkably in recent years. The pathogenicity of the bacteria has not been clarified enough, thus there is no effective control methods. In this study, the progression of M. bovis pneumonia was analyzed. The infiltoration of neutrophils was caused following the cytokine(IL1β, TNF α, IL8) production from alveolar macrophages. B cells were secondarily infiltrated. In cattle with chronic pneumonia, the function of the T cell decreased remarkably. Therefore, this host was suggested to be in a compromised condition. In addition, it was suggested there was the individual difference in host immune response level, and there was the immune stimulating difference between the isolations of M. bovis.
