The epithelial pathology of bovine genital tuberculosis.

The histopathology of the uterine and salpingeal epithelium of five cows affected with genital tuberculosis was studied. Both optical and scanning electron microscopy were used and the results were compared. Various forms and degrees of cellular lesions are described, including hypertrophy, flattening, detachment, nuclear protrusions and alterations of the cilia. In the different sites considered (uterus: intercaruncular and caruncular areas; salpinges: isthmus and ampulla) various characteristic lesions were observed.
