PLATE 3 



Fig. 9. Section of right kidney. Proximal convoluted tubules with deeply 

 stained cells; the abnormal tubules are surrounded by massive infiltration of 

 stroma by monocytes, plasma cells, lymphocytes, and polyblasts. Zenker fixation 

 and Giemsa stain, x 98. 



Figs. 10, 14. Epithelial cells of the tubules filled with intracytoplasmic colonies 

 of brucellas. Some of the cells are still normal, others necrobiotic. x 777. 



Fig. 11. Section through renal tubule with epithelia serving as host cells for 

 brucellas, x 388. 



Fig. 12. Necrotic collective tubule plugged with masses of Brucella. Zenker 

 fixation-hematoxylin stain, x 388. 



Fig. 13. Focal arrangement of monocytes surrounding tubule with cells con- 

 taining brucellas. Zenker fixation and Giemsa stain, x 510.
