[The pathogenesis of otitis externa].
In otitis externa the formerly grampositive colonization of the auditory canal changes towards a gramnegative microbial flora. Pseudomonas aeruginosa plays a major role in recurrent infections and in swimmer's ears. Various serotypes of ps. aeruginosa i.e. type 1;6 and 5 could be isolated. In swimmer's ears ps. maltophilia was identified twice. There was no correlation between the severity of the disease and the protease and lipase activity of pseudomonas isolates. Exoenzyme activity seemed to bear influence on the chronicity of the disease. Therapeutic success led to a decline of enzymatic activity.
