OVINE CASEOUS LYMPH-ADENITIS 211 only a single gland is affected. The relative frequency with which the various glands become the seat of the lesions may be given as follows: prescapular, precniral, superficial inguinal, bronchial, mediastinal, subhimbar, deep inguinal and scrotal. Rarely the suprasternal and mesenteric glands are affected. Sivori mentions the mesenteric glands among those frequently affected. He fails, however, to men- tion the mesenteric glands as the seat of lesions in the detailed descrip- tion of twelve typical cases of caseous broncho-pneumonia caused by the bacillus of Fig. 48. lung op sheep studded with nodules (Gilruth). When first invaded by the bacterium, the adenoid tissue becomes hyperplastic and the gland enlarges to several times its original size. On section the surface is found to be edematous but otherwise normal in appearance. This is followed by the formation of various centers of degeneration which show concentric layers and gradually become confluent. Finally, the total volume of the gland is transformed into a homogeneous, caseous mass. At the same time the distended capsule increases in thickness and forms a sac which confines the semi- fluid, grumous mass. In rare instances the sac ruptures and when close to the surface the contents will be discharged. Under ordinary circumstances, the caseous contents become cohesive and sticky and of the consistency of putty. In very old cases the mass becomes dry and mealy, with little or no tendency to calcification. The greenish-yellow color of the caseous mass, which is stated to be most.
