Three field strains of Mycoplasma dispar were inoculated, by aerosol inhalation, into a total of eight naturally-born, colostrum-deprived calves. All three strains produced macroscopic pneumonia, each in one calf. Histopaithologically an exudative bronchitis accompanied by moderate interstitial cell proliferations was found. Reisolation studies indicated that the entire respiratory tract is the natural habitat of Mycoplasma dispar, which apparently does not spread via the blood stream.
通过气溶胶吸入法,将三株支原体菌株接种到总共八头自然出生、未摄入初乳的犊牛体内。所有三株菌株均引发了肉眼可见的肺炎,每株在一头犊牛身上引发。组织病理学检查发现伴有中度间质细胞增殖的渗出性支气管炎。再分离研究表明,呼吸道是支原体的自然栖息地,显然它不会通过血流传播。
