ULCERATIVE DERMATITIS, THROMBOCYTOPENIA, AND NEUTROPENIA IN FOALS AND ADULTS
 
Description    Foals less than 4-days of age developed transient ulcerative dermatitis, thrombocytopenia, and neutropenia. Affected foals survived and were healthy as yearlings. The cause of this cluster of signs is unknown but it might be associated with colostral antibodies or other factors in colostrum. A similar condition was seen in an adult horse.
