Brucellosis is an infectious disease of manifold symptoms. The eye is one of the many sites of its manifestations, although the disease is relatively rarely recognized through its ocular signs. In its acute or its chronic form, brucellosis is second to no other disease, syphilis not excluded, in its ability to masquerade under innumerable guises.
Of the pathology, only enough will be said to show why the symptoms may be so varied. The organism has been isolated from the heart in cases of endocarditis and pericarditis ; from the lung in cases of pleurisy and pneumonia ; from the liver in cases of necrosis and abscess ; from the gastrointestinal tract in cases of ulceration of the small and large bowel and of appendical infection ; from the mesenteric lymph nodes ; from the spleen in cases of necrosis ; from the fallopian tubes in cases of salpingitis ; from the ovary in cases of infected cyst
