SUMMARY

The present study was conducted on the blood cells of ten apparently healthy Kadaknath fowls. The granules of basophils were stained metachromatically when stained with 1 % toludine blue stain for mucopolysaccharides. Black coloured Sudanophilic granules were observed in the cytoplasm of the eosinophils. Glycogen in the form of light pinkish violet coloured granules was demonstrated by periodic acid Schiff’s stain only in the eosinophils. Acid ferrocyanide stain showed positive reaction in the form of fine blue coloured granules in siderocytes.

The metachromatic reaction of toludine blue was used to evaluate immature basophil population and myeloproliferative disease in human beings (Parwaresch, 1976). The pattern of acid Schiff’s stain reactivity was used to characterize lymphocytic leukemias (Schwarze, 1980). The paucity of literature led to initiate the presen
