Otitis media of guinea pigs.
Otitis media occurred in 177 of 1373 guinea pigs necropsied during a six-year period. Streptococcus pneumoniae (20%), Streptococcus zooepidemicus (15%), Bordetella bronchiseptica (12%), and Pseudomonas aeruginosa (11%) were the most common bacteria isolated from affected tympanic bullae. Radiology and otoscopy were tested as means of antemortem screening for affected guinea pigs. Radiology gave 96% accuracy in diagnosing otitis media and proved to be a more satisfactory technique than otoscopy.
