The infrequency of the occurrence of Bacillus proteus in otogenic infections and the high mortality which it causes make it of sufficient interest to justify reporting the present case.
Since 1912 only 9 cases have been reported in the literature. Seven of the patients gave a history of chronic otitis; all were operated on and 4 had the lateral sinus obliterated and the internal jugular vein ligated. The blood cultures were positive in all but 1 case, and that was the only case in which the patient recovered. The mortality was 89 per cent; 3 patients died of meningitis and 5 of the overwhelming bacteremia.
REVIEW OF THE LITERATURE
Ross1 in 1912 reported the case of a boy aged 9 months who died after an illness of about six days. There had been typical signs and symptoms of meningitis. From the spinal fluid organisms were isolated. Both ears contained pus.
