Abstract: The present study provided quantitative information on the plasma cell in respiratory system of pig without respiratory diseases. Plasma Cells (PC) were counted in the tonsils, epiglottis, trachea and 11 additional anatomical regions of the 2 lungs of adult pigs. Five clinically healthy animals were studied, of approximately 100 kg, serologically negative for Mycoplasma hyopneumoniae, PRRS, Aujesky and Actinobacillus pleuropneumoniae. Samples were processed by paraffin inclusion and stained with green methyl-pyronin. The tonsil (9.42±7.13 ***p>0.001) and right cranial lung lobe (apex) (3.24±4.74) were found to contain the highest amount of PC, while, the lowest amounts were detected in trachea (0.26±0.42) and left cranial lung lobe (apex) (0.6±0.44). These data, obtained from pigs clinically healthy, will enable comparisons to be made in future studies of pigs with infectious respiratory diseases.
