Abstract

The authors encountered a case of Babesiasis in Korean native cative cattle at Gyeongbug prefecture. After the clinicohematological observation the patient was treated a single dose of ganaseg and the following results were obtained. 1. Initial symptoms observed were high fever, anorexia, depression and cessation of rumination and these were followed by marked hemoglobinuria and mild degree of icterus. 2. The erythrocyte count decreased to $3.6{ imes}10^6/mm^3$ and the infected erythrocyte rates were 9.7 percent with Babesia sp. and 0.2 percent with Theileria sp. 3. Marked increase in band neutrophil was observed. 4. The morphology of the protozoa in erythrocytes was different from that of so-called large-type Piroplasma: various forms including paired pear-shaped, single round, oval and pear-orspindle-shaped were detected, of which the former two forms were dominant. 5. A single dose of ganaseg administered intramuscularly was highly effective for the treatment of Babesiasis.
