In the present study prevalence of the resident fungal flora in the healthy dromedary camels’ ears during 2007-2008 was investigated. Total 95 samples were collected using premoistened swabs from the right and/or left external ear canal of 95 dromedary camels and cultured on Sabouraud glucose agar, Blood agar and modified Dixon’s agar media. A total of 27 species of fungus were isolated from 90 of the camels sampled (94.7%). Both filamentous fungi and yeasts were isolated, with a predominance of Aspergillus, Malassezia and Candida species, which were found in 23.9, 21.8 and 18.6% of cultures, respectively. Among the fungal isolates, A. niger (29.5%) and C. albicans (19.8%) were the most prevalent fungal agents, representing significant values in comparison with the other fungal isolates (P<0.05). In addition, 4 certain pathogens identified as Nocardia asteroides, which was not commonly related to fungal flora of animals’ ears, were found. Adult animals (³ 3 years old) were being more frequently colonised (P<0.05).
