Studies on Morphological Differentiation of Babesia bigemina and Babesia argentina Infections Using Smears and Tissue Sections of Organs of Splenectomized Calves


H. M. D. Hoyte
Abstract
The smears and tissue sections of organs (liver, lung, kidney, heart, lymph-node, brain) were carried out to compare the detection of parasites in the splenectomized calves artificially infected with B. bigemina and B. argentina, respectively.
The results obtained from this experiment were abstracted as follows:
1. In the calves infected with B. argentina the parasites were easily detected by the blood smears and tissue smears but, particularly, the detection of parasites in the kidneys and brain by tissue smears and tissue sections was greater useful. In this experiment, the packing of the parasite-infected red blood cells was found in the capillary vessels of the organs.
2. When the fresh infected-brain was kept at 5℃ refrigerator, Babesia argentina could be detected during 9 days from the brain smears. According to this results, we could do differentiate the parasites from the brain of the dead animal by the doubtful babesiosis in the field.
3. If we use the brain smears and brain sections in order to-survey or detect Babesia infections of cattle in Korea, these methods could be worthwhile for the differential diagnosis of B. argentina and B. bigemina.
