Hair samples from 58 healthy camels were examined for the presence of saprophytic fungi. One -hundred and seventy-four samples were obtained from three different locations of dromedary camel's body. Several fungal specific media were used for isolating and identifying the saprophytes. Fungal isolates belonged to 15 genera. The most common in order of frequency were members of the genera Aspergillus (48% of the total examined camels), Penicillium (16.1%), Mucor (14.2%), Alternaria alternata (5.6%), Rhizopus (3.1%), Chrysosporium (2.7%), Acremonium (1.1%), Scoupolariopsis (1%), Cladosporium (0.8%), Fusarium, Psuedallescheria boydii and Stachybotrys atra (0.2%). The highest frequently yeasts isolated were related to Candida species (6%), followed by Geotrichum candidum (0.6%) and Malassezia species (0.2%). Skin infections caused by any of the contaminants were not encountered. The study demonstrates that Aspergillus, Penicillium and Mucor species were the common components of healthy camel skin mycoflora, and that camel hair analyzed in this study was free from true dermatophyte.

Abstract
Fungal agents, especially yeasts, are resident in digestive system as microflora and they can invade the mucosal tract in animals with predisposing factors. The prevalence of the resident fungal flora in the digestive tract of healthy broilers and layers during April to September 2008 was investigated. ...

Fungal agents, especially yeasts, are resident in digestive system as microflora and they can invade the mucosal tract in animals with predisposing factors. The prevalence of the resident fungal flora in the digestive tract of healthy broilers and layers during April to September 2008 was investigated. The samples were taken from the preventriculus, jejunum and cecum contents of 120 birds and cultured on Sabouraud glucose agar. Both filamentous fungus and yeasts were isolated and a predominance of the Candida species was found, followed by Trichosporon beigelii, Geotrichum candidum, Rhodotorula rubra and Saccharomyces cerevisiae species, which were found in 84.6%, 5.5%, 4.6%, 3.3% and 0.5% of cultures, respectively. Among the yeast isolates, Candida albicans (45.8%) was the most prevalent fungal agent, representing a significant proportion when compared to the other fungal isolates (P

Abstract
The aim of this study was to isolate and identify airborne fungi from locations in Babol city, Babolkenar forest and a beach on the Caspian Sea (all in North part of Iran) in spring and summer. Of 126 samples collected, the most clinically important isolated fungi were Mucor spp. (18.6%) in the forest, ...

The aim of this study was to isolate and identify airborne fungi from locations in Babol city, Babolkenar forest and a beach on the Caspian Sea (all in North part of Iran) in spring and summer. Of 126 samples collected, the most clinically important isolated fungi were Mucor spp. (18.6%) in the forest, Alternaria spp. (13.4%) at the beach; and Cladophialophora spp. (15.8%), Mucor spp. (11.7%) and Alternaria spp. (10.6%) in the urban areas. Non-sporulating fungal isolates were grouped in Mycelia sterilia. The concentration of air spora in the forest location was significantly greater than the other locations (p
