Abstract
Bacterial examinations of chronic otitis media from 1976 to 1987 were retrospectively studied. Staphylococcus aureus and Pseudomonas aeruginosa were commonly detected during these 12 years. Proteus species have decreased in detection rate, but glucose non-fermentative gram-negative rod species have increased. Gentamicin-tolerant Staphylococcus aureus have become increasingly more common in recent years.
