Blood samples from eastern sarus cranes housed at Nakhonratchasima
Zoo, Nakhon Ratchasima, northeastern, Thailand were collected in January,
2007. A morphological observation of the thrombocytes was examined using
scanning electron microscopy. The results revealed the following information:
The thrombocytes of the eastern sarus cranes are tiny cells and they display
a smooth, irregular, spherical and pseudopodic membrane surface with long
microfilament protrusions from their membrane. The thrombocytes of the
eastern sarus cranes use these microfilaments to attach to other blood
cells for movement and blood clumping. The long microfilaments were not
found in fish, reptiles and other domestic birds. The morphological structure
of the thrombocyte, the microfilaments and the activities of the eastern
sarus crane has not been reported previously.
