| Summary: | Peripheral blood leucocytes of the turbot, Scophthalmus maximus, were characterised into 4 distinct groups following morphological, morphometric and histochemical examination. Total and differential cell counts were determined. Thrombocytes, the most abundant leucocyte type (52%), were highly mobile and encountered in several morphological forms. Granulocytes, representing 5.6% of the leucocyte population, histochemically most resembled the mammalian neutrophil. Both large and small lymphocytes (40.8%), were encountered. Monocytes were rarely observed (1.6%). Thrombocytes and monocytes were phagocytic in vitro at 12oc and 22oc, showing increased phagocytic activity at the higher temperature. The thymus was paired and consisted of a well developed outer cortex and an inner meduallary region. The spleen was bounded by a fibrous tissue capsule and contained a large volume of blood. Diffuse areas of red and white pulp, ellipsoids and melanomacrophage centres were apparent. Lymphocytes, thrombocytes and mature ... |
