【摘要】 本文报道鸡卡氏白细胞原虫病34例的血液变化。白细胞分类及形态学观察:1.由于鸡的发病时期先后不同,34例中发现裂殖子期的鸡占21只,配子体期的占13只。2.血红蛋白在20％以下的占8只,21～30％的占10只,30～40％的占12只,41～50％的占3只,51％的占1只,3.红细胞每立方毫米有54～91万个的占7只,100～200万个的占19只,200～300万个的占8只,红细胞形态多数呈嗜碱性、多染性、圆形、核疏松呈网状,细胞浆甚少,无性系细胞明显增多;4.白细胞每立方毫米有1.1～2万个的占8只,3.1～4万个的占6只,4.1～5万个的占6只,5.1～6万个的占4只,8.3～10.8万个的占4只,分类尚未发现有规律性变化;5.血小板在1万个以下的占5只,1.1～2万个的占11只,2.1～3万个的占8只,3.1～4万个的占2只,血小板一般体积增大,偏向园形,有些体积接近正常,但核肿大,结构疏松。 本文并结合现代文献资料对血液学的变化进行了讨论。更多还原

【Abstract】 The present paper presents the results of the study on the haematological changes in 34 cases of Leucocytozoon caulleryi infection in chickens.The results obtained are summed up as follows:1 . All the blood samples examined were taken from chicekens of different stages of Leucocyto zoon caulleryi infection, and of the 34 cases 21 were found to be of schizont stage and 31 gametocyte stage.2.Haemoglobin estimation-Eight cases were below 20%, 10 cases 21-30%, 12cases 30-40%, 3 cases 45-50% and only one case was 51%.3.Erythrocytes-s for red cell counts, 7 cases were 540,000-910,000/mm3 , 19cases 1,000,000-2,000 , 000/mm3 and 8 cases 2,100,000-3,000,000/mm3. Morphological alternations in the red cell picture showed that the majority of red cells retained their basop-hilia and appeared to be polychromatophilic and round-shaped. Neuclei were loose in structure and were reticular in appearance,the cells containing very little cytoplasm.peripheral erythropoietic red cells increased evidently.4 . Leucocytes-Total leucocyte countings revealed that 8 cases ranged 11000-20000/mm3 6 cases 31, 000-40, 000/mm3, 6 cases 41,000-50, 000/mm3 , 4 cases51, 000-60, 000/mm3 and 4 cases 83,000-108,000/mm3. No regular pattern of changes in the leucocyte picture was found in differential leucocyte counts.5. Thrombocytes--In platelet counts, 5 cases were below 10,000/mm3, 11 cases11,000-20,000/mm3,8 cases 21,000-30,000/mm3, and 2 cases 31,000-40,000/mm3. Morphologically, they were in general enlarged in size and tended to be round-shaped. Some of them were nearly normal in size, but their nuclei were loose in structure,A brief discussion based on current literature on the haematological changes was also made in this paper.更多还原
