To determinate postinfectious antibodies for porcine proliferative enteropathy were studied 24 blood samples from each 5 farms arranged in the west of Romania coming from different age pigs, using MegaScreen®FLUO LAWSONIA (Diagnostik Megacore) kit. All studied farms proved the present of Lawsonia intracellularis infection. Seroprevalence within herds fluctuated between 33 and 54%. Age depending, dynamics of seroprevalence knows an increase at 91-140 days category and a decrease at finishing-slaughtering period. Thus, it was obtained a seroprevalence average of 32,8% at 45-90 day category, increasing to 71,9% for 91-140 days category and reaching to 62,5% in the last period of swine exploitation.
