Abstract

Enzootic pneumonia by Mycoplasma hyopneumoniae and pleuropneumonia by Actinobacillus pleuropneumoniae are among the most common and economically relevant pulmonary diseases in swine herds. We herein investigated the activity and expression of 5-lipoxygenase (5-LOX) and cyclooxygenase-2 (COX-2) in healthy and diseased porcine lungs, by means of immunohistochemical, immunochemical and biochemical assays. Diseased lungs showed a significantly higher activity and expression of 5-LOX and COX-2 in a wide range of cell types, thus suggesting the likely involvement of both enzymes in the pathogenesis of bacterial porcine pneumonia. Consistently, increased enzyme activities were paralleled by increased leukotriene B4 (LTB4), a 5-LOX product and prostaglandin E2 (PGE2), a COX-2 product, content in diseased versus healthy lungs.
