RESUMO
This pilot study was to determine if early oral flea exposure reduces the incidence of flea allergy dermatitis (FAD) in cats. Eighteen kittens, assigned to three groups, received no flea exposure, oral flea exposure or flea infestation for 12 weeks. Then all the kittens were exposed continually to fleas for 31 weeks. Sensitization was monitored using intradermal testing (IDT), in vitro measurement of anti-flea saliva immunoglobulin E (IgE) and development of FAD. There was no statistically significant difference between groups in IDT reactions, in vitro data or clinical scores. The development of FAD was not associated with the presence of anti-flea saliva IgE. However, the development of a delayed reaction to flea bite was associated with symptoms after flea exposure. Although not statistically significant, the FAD scores in the oral group were lower than in the controls. Further studies are required to determine the role of oral flea exposure in the development of FAD in cats.

Recent advances in our knowledge of cat flea biology and the discovery of new nontoxic control methods have greatly simplified and improved flea control. Instead of relying on adulticides for the bulk of flea control, the veterinarian now focuses on the immature stages, particularly the larvae and the eggs. By doing this, environmentally "friendly" flea control methods are employed that are much safer for the veterinarian, the pet owner, and the cat.

Otitis externa can be a complicated and difficult disease to diagnose and treat. Because of the unique physiology of the ear canal and common pathophysiology of otitis externa regardless of the underlying cause, the clinician must rely on history, dermatologic examination, and ancillary tests to determine the cause and appropriate therapy for a particular case.
