这个词是什么意思？
A species of gram-negative bacteria that causes MYCOPLASMA PNEUMONIA OF SWINE. The organism damages the CILIA in the airways of the pig, and thus compromises one of the most effective mechanical barriers against invading pathogens. The resulting weakening of the IMMUNE SYSTEM can encourage secondary infections, leading to porcine respiratory disease complex.
