1. Bacillary white diarrhea probably is present wherever poultry husbandry is practised. The infection has been found in 71 of the 100 countries of North Carolina. The disease is highly contagious and is productive of great monetary loss to the poultrymen of the State.
2. The disease produces a septicemis condition in chicks, resulting in a pathological condition of the internal organs. The lesions produced are fairly constant, and are typical of the disease.
3. The disease may assume a virulent form in adults. The clinical history of infected adults shows slight deviations in respiration, elevation in temperature, a leucocytosis in the blood, and is not usually fatal.
4. Studies of the carrier bird show that the focalized condition of the disease does not noticeably affect the respiration; there may be temporary elevation of temperature; the annual body weight curve follows that of normal birds; there is a distinct tendency to nest more often than the normal bird, and that the death rate in carrier birds is abnormally high.
