FIGURE 2 in Age-associated hemogram and ultrastructural leukocyte morphology in Pygocentrus nattereri (Characiformes: Serrasalmidae) from the Brazilian Pantanal

FIGURE 2 | Erythrocytes, thrombocytes and lymphocyte in Pygocentrus nattereri from Brazilian Pantanal in light (A, B, C) and transmission electronic microscopy (D, E, F). A and D. Thrombocytes of elongated shape and scarce cytoplasm rich in canalicular system (arrow). B and E, monocytes of irregular shape, chamfered nucleus, abundant cytoplasm mitochondria (m), vacuoles (v), glycogen granules (g), Golgi apparatus (G), and free ribosomes (r) are also observed. C and F. Small lymphocyte with numerous projections, a large nucleus, and scarce cytoplasm with few mitochondria and organelles. ABC. May Grunwald-Giemsa-Wright stain. Scale bars = A–C = 10 µm; D–F = 2 µm.
