Quantification of mononuclear cells and CD3+, WC1+ and CD21+ lymphocytes in baseline, stressed and tick-bitten skins of tick-resistant (white boxes) and tick-susceptible (gray boxes) bovines. a Numbers of mononuclear cells/mm2 in paraffin-fixed sections stained with May-Grünwald and Giemsa. b-d Numbers of CD3+, WC1+ and CD21+ lymphocytes (Fig. b-d, respectively) in cryopreserved sections stained with peroxidase-immunohistochemistry in a depth of 0.0625 mm2 into the dermis. Values followed by the same capital letter differ significantly (P < 0.05) between different types of skin from the same breed. Asterisks indicate significant (P < 0.05) differences in comparisons between the same types of skin from different breeds
