New opinions regarding Paullorum Disease. Nouveaux points de vue sur la pathogenie, le traitement et La prophylaxie de la septicémie des volailes dae à la Salmonella pullorum. Dr. J. Ch. Sparaparri. La Revue Avicole, 1937, p.453.

The pullorum bacil in itself does not cause the disease. It is only when the chickens are in a weakened state that the disease appears and then the bacilli are able to increase considerably. The writer considers lack of certain vitamins (A., B, C) to be the cause of weakness. This lack of. vitamins need not be present to such an extent as to cause avitaminosis, but only to such a degree as will cause a decrease of the powers of resistance in the body to the increase of the pullorum bacilli. The writer cured several chickens suffering from pullorum by a method of his own. In experiments carried out according to Harde's method a smaller quantity of vitamin C was found in the livers of sick chickens than in those of healthy ones. The quantity of vitamin A. was also smaller. Cure was affected by subcutaneous injections of Vit. A, B, and C.
