Coproporphyrin I and coproporphyrin III were isolated from the faeces and urine of cattle suffering from East Coast Fever. 2. The ratio of the I to the III series in the faeces of one animal was 1 : 1.15, whilst in that of another only traces of the I series could be detected. 3. In an accumulated sample of coproporphyrins extracted from the urine of East Coast Fever cattle the ratio of the I to the III series was found to be 1 : 0.31.en© 1938 ARC - Onderstepoort and Faculty of Veterinary Science.
