| Abstract |
|
For the ultrastructural observation on Babesia gibsoni(B gibsoni), the protozoa were challenged experimentally to splectomized dog. To examine the ultrastructure of the B gibsoni in the erythrocyte, the infected erythrocytes were collected at the cephalic or jugular vein of the dog. The results obtained by TEM(transmission electron microscopy) were as follows; 1. The sizes of protozoa in erythrocytes are $0.92{pm}0.36{mu}m{ imes}0.67{pm}0.21{mu}m$, the sizes of nucleus of the protozoa are $0.55{pm}0.24{mu}m{ imes}0.38{pm}0.26{mu}m$, and sizes of rhoptries in plasma of the protozoa are $0.33{pm}0.05{mu}m{ imes}0.25{pm}0.07{mu}m$, respectively. 2. The tropozoite membrane in the erythrocyte was one, and it's nuclear membrane was made up of double. But the protozoa of initial stage in infected erythrocyte had double clear mambranes, and distinguished from plasma membrane of red blood cell. 3. The mitochondrialike structures covered with two membranes were observed in the protozoa. 4. Mitochondria and vesicles of the reticulocyte were observed near protozoa in the erythrocyte. 5. There are rhoptry, coiled structure and single nucleous in the merozoite. 6. The shape of rhoptry was round or ovoid form and in occasionally, the content of rhoptry was lost partially. 7. There was able to observe the dividing process of the protozoa. 8. Maurer's cleft-like structure was observed. |
