The examination of the reliability of ultrasonography for the diagnosis of meniscal injuries in dogs by surgical verification

MS infection most frequently occurs as a subclinical (infection with no clinical signs) upper respiratory infection. It may cause respiratory signs when combined with other pathogens, such as infectious bronchitis virus. MS receives its name, because occasionally the bacteria become systemic and result in infection of the membrane that covers the joints (synovium). Clinical signs are observed when joints become affected. The birds become pale comb, lame, and have retarded growth. Swelling of the joints and breast blisters may be observed. Infection of the respiratory tract may result in inflammation of the air sacs, which result in higher condemnations of meat birds at slaughter. Egg production is minimally or not affected at all. Eggs produced by an infected flock are suitable for human consumption.
