Clinical and Hematological Studies on Hemolytic Icterus of Foals

Abstract

Ten cases of hemolytic icterus of foals were studied clinically and hematologically. The results obtained are summarized as follows. 1. The mode of occurrence of the disease in question and the clinical signs of diseased foals coincided with those of the hemolytic icterus of foals reported already. 2. Anemia, high icterus index, appearance of erythrophages and sideroleu kocytes, and reduced red blood cell fragility were characteristic findings in the blood. 3. The red blood cells of diseased foals were hemolyzed in the hemolytic test. They were positive for the direct Coombs' test. 4. Erythrophages and slight or almost perfect destruction of red blood cells were seen by electron microscopy.
