Platelets are found in the blood of all mammals and serve the same basic hemostatic functions in all. Species differences in the morphology and activities of platelets in human and domesticated animals have been observed, but there is little published information regarding the blood pictures of wild animals. In this study, the ultrastructure of buffalo platelets was compared with that of bovine and human platelets. Buffalo platelets were found to be smaller than human platelets and intracellularly had larger alpha-granules, possessed distinctive dense granules and a more distinct microtubuli system, but they lacked the open canalicular system observed in the human type. This morphology is similar to that of cattle platelets.
血小板存在于所有哺乳动物的血液中，且在所有哺乳动物中发挥相同的基本止血功能。人们已经观察到人类和家养动物血小板在形态和活性方面存在物种差异，但关于野生动物血液图片的公开信息很少。在本研究中，对水牛血小板的超微结构与牛和人类血小板的超微结构进行了比较。发现水牛血小板比人类血小板小，细胞内有更大的α颗粒，具有独特的致密颗粒和更明显的微管系统，但它们缺乏人类血小板类型中观察到的开放管道系统。这种形态与牛血小板的形态相似。
