Popis: ABSTRACT: This study aimed at performing cytometric phenotyping of the blood samples from free-living, young white-eyed parakeets (Psittacara leucophthalmus), stained with 3,3-dihexyloxacarbocyanine [DiOC6(3)]. DiOC6(3)-stained whole blood samples from 19 free-living, young white-eyed parakeets were analyzed by flow cytometry and cell types were distinguished by their typical fluorescence in blue laser channel (FL-1) and SSC (side scatter). It was possible to differentiate erythrocytes (58.3±13.6) from leukocytes (32.4±13.1) and some of the leucocyte subpopulations: lymphocytes/thrombocytes (29.7±7.7), monocytes (30.6±8.5), and granulocytes (5.9-26). However, lymphocytes and thrombocytes could not be sorted in the plots. Our study determined that the predominant population in white-eyed parakeet (P. leucophthalmus) was lymphocytes, thrombocytes, and monocytes in the leucocytes gates in comparison to the granulocyte population. The cytometry method and use of DiOC6(3) stain was available for parakeets blood samples and can be studied and applied to other species of parrots.
