Summary Isolation and diagnosis of some fungal types from external ear canal infection cases with sensitivity test to some antifungal agents

Abstract

This research included isolation of some types of fungi of molds and yeasts from cases of inflammation of
external ear canal in human from AL- yarmouk Teaching Hospital, by collection of 50 samples from males and
females and from different ages during summer season , also 10 samples from non infected cases were taken as
control. Also sensitivity test of some isolates against some important antifungal agents which commonly used
in the treatments of infection of external ear canale cases.
After cultivation of isolates on saboroud dextrose agar, diagnosed as follows :
9 isolates of Aspergillus niger, 6 isolates of Aspergillus fumigatus, 3 isolates of Aspergillus flavus, one isolate of
Aspergillus terrus, 10 isolates of Candida albicans, 5 isolates of Candida tropicalis, 2 isolates of Candida
parapsilosis.
The results of the sensitivity tests of some isolates against the antifungal agents appeared as follows: the isolates
of Aspergillus spp. were very sensitive to Clotrimazole and Econazole, while were less sensitive against
Nystatine.
Whereas the species of Candida were very sensitive to Nystatine and Econazole, but less sensitive against
Clotrimazole.
