Sažetak
The present study tested the hypothesis that levamisole exerts its immunopotentiating activity in weaned pigs vaccinated against colibacillosis by priming the lymphocytes and macrophages in the mesenteric lymph node (MLN). Ten weaned piglets were used and allocated into two equal groups. The experimental group was intramuscularly primed with levamisole at an immunostimulatory dose of 2.5 mg/kg given daily, in three consecutive days, and controls received saline according to the same schedule. Both groups were orally vaccinated with the vaccinal Escherichia coli strain on day zero and challenged with the virulent E. coli strain seven days later. All pigs were sacrificed on post-challenge day six. The health status of the two groups upon virulent challenge was evaluated by clinical observations and expression of CD25, SWC7 and SWC9 activation antigens by MLN and spleen T and B cells and macrophages, respectively, was tested using flow cytometry. Priming by levamisole significantly contributed to the effectiveness of a live attenuated oral vaccine against porcine post-weaning colibacillosis, as evidenced by a good health status of primed vaccinated vs un-primed vaccinated pigs. The CD3+, CD25+ and SWC9+ MLN but not spleen T cells and macrophages increased in experimental vs control pigs, implying that levamisole exerts its potentiating activity in the MLN by augmenting both recruitment and activation of cells that participate in cell-mediated immunity.
