We report on the bacterial flora of the external ear canal and of induced aural cholesteatoma in 14 Mongolian gerbils ( Meriones unguiculatus). In the control, nonmanipulated external ear canal, gram-positive and gram-negative organisms were isolated. In the contents of the cholesteatoma sac, only monomicrobial, gram-negative isolates were found; in each animal they were different from the isolates from the nonmanipulated external ear canal. Obligate anaerobes were absent in all cases. Ligation of the external ear canal in the left ear provoked cholesteatoma in all cases.

Epithellal migration on the tympanic membrane of young and aged gerbils was studied; Sudan black B was used as a marker dye. The epithelial migration center was found at the region of umbo, manubrium, and the short process of the malleus. The epithellal migration rates of the gerbiis aged 3 to 6 months, 9 to 12 months, and 24 to 30 months were approximately 116, 113, and 86 μm per day, respectively. These findings suggest that the low epithelial migration rate on the tympanic membrane and external ear canal might play an important role on the high occurrence rate of external ear keratosis that results from accumulation of keratin debris in the aged gerbil ears.
