摘　　要：本文报道了火鸡组织滴虫在孔雀肝脏和肾脏中的发育及其致病作用。结果表明,肝肾中虫体的分裂方式为典型的二分裂繁殖法;肝脏和肾脏表面分布有从芝麻到绿豆大小不等的黄白色坏死灶;肝肾细胞坏死,有大量淋巴细胞浸润。This paper dealed with the development and pathogenicity of Histomonas meleagridis in the liver and kidney of naturally infected peacocks. The discrete focal necroses with yellowwhite colour and different size were scattered on the surface of liver and kidney. Under the light microscope, large numbers of lymphocytes infiltrated in the lesions, and the hepatocytes and kidney cells in the centers of the lesions were necrotic and disintegrating. Numerous histomonads were visible in the liver and kidney by light microscopy, and most of them were spherical or oval in shape with a rounded nucleus. Some organisms were in the process of reproduction. Multiplication of the organisms was initiated with the division of nucleolus into two mucleoli which were located in the same nucleus. Subsequently, the nucleus divided, and gave rise to two daughter nuclei, each of which contained a nucleoles. Following the nucleus division, the cytoplasm invaginated, and then two developing daughters connected only by a bit of cytoplasm. Eventually, two new daughter cells, which were morphologically identical to the mother cell, were formed. The results proved that H. meleagridis reproduced in the liver and kidney by binary fission.
