A new stain for identification of avian leukocytes.
Differential staining of avian leukocytes was achieved within 6 min following brief fixation in a methanolic solution of C.I. acid red 360 followed by immersion in a mixture containing C.I. basic blue 41, C.I. basic blue 141, and C.I. acid red 52. Heterophils contained black angular and punctate granules. Eosinophils contained bright purple granules. Lymphocytes displayed red nuclei and blue cytoplasm. Monocytes contained red-brown nuclei and lavender cytoplasm. Basophils showed red-orange granules. Thrombocytes stained deep purple. Compared to traditional panoptic stains like Wright's or Giemsa's, the new staining method provides brighter colors, more precise details of cellular structures, and shorter staining time. Significantly, it facilitates identification of avian leukocyte species based on differences in color as well as differences in size and shape.
