ABSTRACT

Enzootic pneumonia (EP) is characterized by high morbidity and low mortality, and although pigs of all ages are susceptible to Mycoplasma hyopneumoniae infection, a variety of other respiratory pathogens plays an important role in the development of Porcine Respiratory Disease Complex (PRDC) like Actinobacillus pleuropneumoniae, Bordetella bronchiseptica, Pasteurella multocida, Streptococcus suis, influenza virus and porcine circovirus type 2 (PCV-2). A total of 280 pig lungs with typical EP lesions were processed by molecular techniques. M. hyopneumoniae and M. hyorhinis were detected as a result of bacteriological cultures. Streptococcus suis type II, P. multocida, Streptococcus spp. and S. equisimilis were found in lung tissue samples. These results are a contribution to the knowledge of the enzootic pneumonia and the factors should be kept in mind in future works for the control of this entity. This research sets the basis for more complete studies of EP molecular epidemiology in Cuba.
