Extract

In 1915 Wickware reported on an investigation at Ottawa, of a serious disease which had appeared anlong ducks. Examination of the blood of affected ducks showed the presence of a protozoon parasite which Wickware named Leucocytozoon anatis. O'Roke (1930) reports that the disease is apparently not harmful to adult ducks, but is pathogenic to ducklings, the mortality being 35 per cent in the cases studied.
