Bacteriologically a micro-organism was invariably found in the blood, organs and tissues. It possesses the characteristic morphology, biology, and experimental effects which are detailed in Appendix.
Experimentally the investigation was limited to the question of the causal relationship of the micro-organism to the disease. That such a relationship exists is fully proved by the insemination of a pure culture of the micro-organism in question into a previously healthy animal and its subsequent contraction of the disease in typical form and with typical results.
For full data in regard to the post-mortem results and micro-organismal nature of the disease, reference may be made to Appendices attached.
The following is a comparative statement of the differences and resemblances between this disease and Rinderpest :-
This Disease
DIFFERENCE BETWEEN
1. Micro-organism constantly present. 2. Mouth lesions extremely rare. 3. No skin eruption.
and
4. Trachea and bronchi normal or con-
gested.
Rinderpest.
1. No micro-organism.
2. Mouth lesions constantly present. 3. Skiu eruption commonly present.
4. Trachea and bronchi show croupous
changes.
RESEMBLANCES BETWEEN
This Disease and Rinderpest.
1. Rapid emaciation and weakness common to both.
2. Diarrhoea.
3. Intestinal lesions.
4. Hæmorrhagic lymphatic glands. This condition is constant in the
disease under consideration. It is common in Rinderpest.
5. Cardiac petechiæ.
Our conclusions are as follows:-
1. The disease is a form of Hæmorrhagic Septicemia,
2. It has no connection with Rinderpest.
3. It is allied to Pasteurellosis.
