Paralysis of hind limbs in caprine reproducer caused by Lymphadenitis Caseous in Sergipe State

Abstract

A buck Anglo Lubiana breed of four years, used in intercropping for four owners presented sudden hindlimb paralysis and subsequent sternal decubitus, during the breeding season. In the clinical examination of the billy-goat, the same showed sensitivity until the region of the last thoracic vertebrae (T11 to T13), however, after this region the animal no presented sensibility and haven´t muscle tone and in the part cranial presented sensitivity and normal motor activities.  In the radiological examination detected an increase in the intervertebral space between T11 and T12 and T12 with caudal displacement and consequent reduction of the space between T12 and T13. The billy-goat did not respond to conservative medical treatment and was euthanized. In the necropsy was seen a bilateral fracture of the transverse processes in the dorsal region of the last thoracic vertebrae and extravasation of caseous material.  Ventral to the point of injury, inside of thoracic cavity was observed increased volume enclosed by capsule of dimensions of 7.0 x 4.5 cm, in position half right of vertebrae. The insulation material was identified as the etiologic agent Corynebacterium pseudotuberculosis. The use of billy-goats in intercropping exposes them to different types of sanitary management, increasing the risk of infection and spread of  Lymphadenitis Caseous among the herds, mainly because it's easy and rapid spread causing major economic and genetic damage, especially when there is formation of abscess  in viscera leading to death.
