Bronchpneumonia as a health problem on pig farms (research review)

Abstract

Bronchopneumonia is one of the most important respiratory diseases in pigs in intensive breeding. Bronchopneumonia rarely occurs and passes as a monoinfection, and therefore mixed infections are the most common finding. Isolated microorganisms include, for example, Porcine reproductive and respiratory syndrome virus (PRRSV), Porcine circovirus type 2 (PCV-2), Mycoplasma hyopneumoniae, Influenza virus, Actinobacillus pleuropneumoniae, Pasteurella multocida, Bordetella bronchiseptica. Of particular importance in the development of bronchopneumonia in pigs are non-specific factors, such as transport, low temperature, inadequate nutrition, environmental conditions in the boxes, overcrowding and other stressors. Pulmonary pasteurellosis is the result of a lung infection with the bacterium Pasteurella multocida. It most often occurs as the last stage of enzootic pneumonia or a complex of respiratory diseases in pigs. The complex of respiratory diseases is one of the most common and economically most expensive diseases of pigs, especially if the pigs come from commercial farms. Pulmonary pasteurellosis is present in different housing conditions of pigs. P. multocida as a frequent resident of the nasal flora of pigs is difficult to eradicate since it can interact with many other pathogens. The aim of our study was to examine the antimicrobial susceptibility of bacterial isolates originating from pigs in intensive production.
