Summary:The eosinophil leukocytes of fishes contain no peroxidase activity while, in general, those of animals higher than fishes, are peroxidase positive. However, there are exceptions to these general findings as follows: 1. Although the eosinophil leukocytes of American urodeles such as Triturus viridescens viridescens and Pseudotriton ruber, are peroxidase positive, those of many other urodeles examined are peroxidase negative.2. In reptiles, only the eosinophil leukocytes of the Trigonocephali and the Gecko japonicus are peroxidase negative.3. In these exceptional cases, however, the neutrophil leukocytes are generally intensely peroxidase positive, suggesting that there is a dissociation in hematopoiesis between eosinophil leukocytes and neutrophil leukocytes. In electron micrographs of the eosinophil leukocytes in the penhepatic zone zone of Triturus viridescens viridescens, the reaction products of peroxidase activity were evidenced in the form of dense material localized in the eosinophil granules in the cytoplasm. Neither mitochondria nor any other components in the leukocyte showed increases in density. The eosinophil granules of the salamanders such as Triturus viridescens viridescens, Ambystoma maculatum and Triturus pyrrhogaster did not possess an internal structure comparable with the central core of the human eosinophil granules.
