N2 - Although recent studies have begun to describe and quantify IgE responses in bovine serum and secretions, little is known about the distribution and quantity of IgE containing cells in cattle. In the present study, cells with cytoplasmic IgE were quantitated in bovine lymphoid tissues, using immunoperoxidase staining and evaluation by an image analysing computer (Quantimet). Frozen sections from retropharyngeal, bronchial and mesenteric lymph nodes, tonsil and spleen were stained from 11 calves, some of which had been exposed to antigen by aerosol or injection. Although individual variability was considerable, bronchial and mesenteric lymph nodes generally contained the greatest percentage of IgE containing cells, while retropharyngeal lymph node, tonsil, and spleen had less. Parenteral immunization with ovalbumin appeared to increase the splenic percentage, while aerosol exposure to ovalbumin was associated with a greater percentage of IgE containing cells in bronchial lymph nodes. Comparison of the present results with those reported for other species shows some similar trends in IgE localization.
