That certain species of Bacillus proteus are pathogenic to man has gradually been proved. Infections with this organism frequently accompany urologic conditions and summer diarrhea of children. Such infections, always associated with other organisms, occur in other parts of the body. If looked for the bacillus would probably be observed more frequently in infections of the throat, nose and ear.
Reports in the literature are gradually accumulating to show that the cases of B. proteus septicemia associated with acute otitis media, acute mastoiditis and peritonsillar abscess, with consequent venous thrombosis and septicemia, carry a high mortality.1 In 1935 Smith and Miller2 reported a case of thrombosis of the lateral sinus caused by B. proteus. Positive cultures of material from the lateral sinus and the blood were obtained. The history was that of chronic otitis media complicated by thrombosis of the lateral sinus and septicemia.
