congenital tremor s.
|
any of several similar congenital neurological diseases of pigs in which piglets have noticeable trembling, often owing to defective myelination of nerves. Mild varieties may clear up within a month but in severe cases the piglets cannot function normally and soon die. One variety is autosomal recessive; another is sex-linked; and others are caused by intrauterine viral infections such as with hog cholera virus. Affected pigs are called dancing or shaker pigs. Called also congenital trembles and myoclonia congenita.
