Mycological studies on otitis externa in dogs

ABSTRACT

Fifty dogs suffered from otitis externa which did not respond to antibiotic treatment were subjected to both clinical and mycological investigation, in a trial to detect the possible mycotic causative agent as well as 32 fungal isolates were isolated and characterized from normal dogs. By studying the effect of different antimycotic agents upon Pityrosporum canis, it was the predominant isolate [66.66%], and it was found to be more sensitive to clotrimazole and ketoconazole [100%], while miconaziale and epiconazole recorded 82.5% and nystatine 70%, but the fungus was not sensitive to amphotericin-B and 5-flucytosine
