Title: The fine structure of granules in eosinophil leucocytes from aquatic and terrestrial birds. Author: Maxwell MH. Journal: Tissue Cell; 1978; 10(2):303-17. PubMed ID: 566969. Abstract: The ultrastructure of eosinophil granules from various aquatic and terrestrial birds has been described. Granules of three basic types were found. The first had a crystalline internum and was found only in the order Anseriformes, which included the black-necked screamer, ducks, geese and swans. The crystals occurred in three morphological forms. The second and least common granule examined contained a non-crystalline internum which was either homogeneous or composed of microfilaments or microtubules. The largest and most common group of birds had a homogenous granule with no internum shown. Homogeneous granules occurred less frequently than did those with interna.[Abstract] [Full Text] [Related] [New Search]
