A Deficiency Disease of Foxes

Abstract

A common and highly destructive dietary disease of silver foxes in captivity is pathologically the counter-part of Wernicke's hemorrhagic polioencephalitis of man. The disease in foxes is caused by feeding fish as 10 per cent., or more, of the diet. It is probable that the fish induce a B(1) avitaminosis which causes the characteristic pathology and the resultant symptoms.
