RESUMO
A total of 330 dust and soil samples collected from different sites at 13 elementary schools and seven public parks in the province of Isfahan, Iran were examined for the frequency of keratinophilic fungi by the hair-baiting technique. Two hundred and fourteen isolates of keratinophilic fungi belonging to seven species were identified. The most frequent isolate was Chrysosporium keratinophilum (54.2%). The frequency and distribution of these keratinophilic fungi are discussed in relation to the presence of children in these environments.

The incidence of opportunistic fungi in bronchoalveolar lavage specimens from patients suspected of tuberculosis in Isfahan, Iran, was determined. From 200 patients 36 yeasts (18%) and seven filamentous fungi (3.5%) were isolated. Out of 44 patients who had fungal infections, 12 cases were affected with definite tuberculosis.

In this study the prevalence and causative agents of dermatophytoses in Isfahan, a large province of Iran, were determined. Of 16,578 clinically suspected cases 13.3% were affected with dermatophytoses. Lesions of tinea capitis were the most prevalent clinical type of dermatophytoses (54.1%), followed by tinea corporis (23.8%) and tinea pedis (8.9%). Trichophyton verrucosum was the most frequent causative agent (32.8%), followed by Epidermophyton floccosum (17.6%), T. mentagrophytes (16.2%) and Microsporum canis (12.3%). We found a relationship between the spread of dermatophytoses and live-stock infected with dermatophytoses in Isfahan.

In this study, bronchoalveolar lavage (BAL) specimens from 247 immunocompromised patients were investigated for the incidence of opportunistic fungi. In the direct examination and culture of the specimens, 5 (2.02%) of filamentous fungi and 55 (22.26%) yeasts were isolated and identified as follows: Aspergillus fumigatus (2), A. terreus (1), A. nidulans (1), Mucor sp. (1), Candida albicans (29), C. glabrata (3), C. Parapsilosis (1), Trichosporon beigelii (1), Candida sp. (13) and unknown yeasts (8). In addition, one strain of Nocardia asteroides and two strains of Streptomyces sp. were isolated.

During the one-year period of this study, 288 samples were taken and 954 fungal colonies were isolated from the air of Isfahan, Iran. Among the fungi isolated, Cladosporium, yeasts, Penicillium, Aspergillus and Alternaria were the most frequent isolates respectively. This study showed that environmental factors affect the number and types of airborne fungi, opportunistic fungi, in Isfahan. Sampling location was an important factor: there were more fungal colony counts in the centre and populated locations of the city than in the less populated and rural areas. Regarding collection time, the most colony counts were obtained from samples collected at mid-day and the least in the morning. This study indicated that the incidence of airborne fungi with clinical significance had a direct relationship with the variation of environmental conditions. The results of the present study contribute towards a better understanding of the pattern of occurrence of airborne fungi, and may be useful for allergists, clinicians and epidemiologists.

The present study determined the extent and causative agents of dermatophytoses in Esfahan, a large city of Iran. Specimens from patients were examined for etiologic agents by direct microscopic procedure and by culture. Out of 12,000 patients with skin diseases, 10.8% were affected with dermatophytoses. Among the 10.8% group, lesions of tinea capitis were most common (72.1%) and Trichophyton verrucosum was the most frequent (43.8%) dermatophyte isolated from the patients. We found a relationship between the spread of dermatophytoses and live-stock infected with dermatophytoses.
