eosinophilic

Certain structures take up only acid dyes, and are called acidophilic, oxyphilic, or eosinophilic.

Myelocytes are named according to the character of their granules—neutrophilic, eosinophilic, and basophilic myelocytes.

Nuclei, basophilic granules, and all blood parasites are blue; erythrocytes are red or pink; eosinophilic granules, bright red.

Eosinophilic leukocytes are common in gonorrheal pus and in asthmatic sputum.
