Pathogenesis of otitis externa and otitis media in dogs and cats

Medical therapy of otitis externa and otitis media.

Medical regimens for the successful treatment of infectious otitis may vary widely depending on the degree of pathologic changes of the external ear canals, the status of the tympanic membranes, and the specific microorganisms involved. Chronic otitis media is especially problematic, because impaction of the bullae can be difficult to resolve and these cases often involve antibiotic-resistant b...

Diagnosis and treatment of otitis media in dogs and cats.

Otitis externa/media is commonly found in dogs with chronic ear diseases and in cats with upper respiratory disease and polyps. Diagnosis of otitis media requires attention to history and clinical signs, but it also requires other methods of determining disease within the bulla. If the integrity of the eardrum cannot be determined, assume that there is middle ear disease and proceed accordingly...

Microbial Evaluation and Management of Otitis Externa in Dogs

The study was conducted to record the microbial inhabitants of the nirmal ear canal and isolate microbial infective agents in otitic ears in dogs. The microorganisms were isolated from 87.5% of normal ears, which included Staphylococcus spp. (37.5%) followed by S. pyogenes (25.0%), P. aeruginosa (12.5%) and E. coli (12.5%). The fungus Candida spp was isolated from 37.5% normal ears, which was a...

Otitis externa in dogs: microbiology and antimicrobial susceptibility

The aims of the study were to determine the prevalence of bacterial/yeast otitis externa in dogs and to analyse antimicrobial susceptibility. Among 257 swab ear samples from Bulgarian dogs with otitis externa, bacteria and yeast species were isolated in 93.77% of cases as mono-infections (109 cases) involving mainly coagulase positive staphylococci (60 strains), Malassezia pachidermatis (97 str...
