Evaluation of camel neutrophil s structure and ultrastructure is essential for fundamental and applied research on innate immunobiology. There is little information on camel neutrophil s ultrastrucure. Healthy camel blood neutrophils were isolated, prepared, and stained for light, scanning, transmission electron microscopy, and organelles biometry. We observed that (1) the nuclei of healthy camel neutrophils were highly lobulated, predominantly ≥5 lobules/nucleus, with euchromatin and hetrochromatin portions and very low ratio of nucleus to cytoplasm, (2) surface of neutrophils contained many psuedopods, and (3) the cytoplasm contained enormous granules with different sizes and forms and high density at the center, as well as with many different organelles such as abundant mitochondria, rough endoplasmic reticulum, microtubules, phagolysosome, vacuoles, and Golgi apparatus. Biometric analyses of key organelles in neutrophils also shed some new lights on the features of camel neutrophils. This ultrastructural study emphasizes the notion that camel neutrophils are highly equipped with the cytoskeletal machinery for efficient organelle movement, phagocytosis, and microbicidal activities. The ultrastructural features of camel neutrophils observed in this study would be outstandingly comparable to the neutrophils of other ruminants and needs further detailed comparative study.
