Flow cytometric analysis of leukocyte populations in the bronchoalveolar lavage fluid (BALF) of healthy and diseased camels. A Gating strategy for the identification of BALF leukocytes. Camel BALF leukocytes were classified based on their forward (FSC) and side (SSC) light scattering characteristics into a major population of FSC^high/SSC^high macrophages, a smaller population of FSC^low SSC^high granulocytes, and two minor populations of FSC^high SSC^low monocytes and FSC^low SSC^low lymphocytes. B Total leukocyte count and the percentage of macrophages (C), granulocytes (D), monocytes (E), and lymphocytes (F) in BALF from healthy and diseased camels were calculated and presented graphically as mean ± SEM. * indicates a significant difference between the two groups (p < 0.05; t-test)
