Abstract:
Mycopasmatic or enzootic pneumonia is the most common disease of the respiratory system under in the intensive pig
production. It is clinically manifested by coughing, a chronic inflammatory process in the lungs, high morbidity and a
relatively low percentage of deaths. The infection can be transmitted horizontally and vertically. Mycoplasma
hyopneumoniae invades the epithelial cells of the trachea, bronchi, bronchioles and alveoli and disrupts the function of
the ciliary body. Evagination of epithelial cells occurs, so that the cleansing of the airway mucosa by the mucociliary
apparatus is inhibited. As a result, bacterial complications (Pasteurella, Bordetella, Klebsiella, Actinobacillus,
Hemophilus) are common.M.hyopneminia can play imortant role in PRDC. The development of Mycoplasma
hyopneumoniae is favoured by large congregations of pigs in small spaces, inadequate environmental conditions
(microclimate), parasitic infections and inadequate nutrition. Mycoplasma hyopneumonia can be a significant health
problem on the fattening farm, exacerbated by the influence of non-specific factors as well as the spread of other
bacterial pathogens.
