Microbiota fúngica de um prédio com laboratórios da região de Araraquara-SP

From September 2000 to January 2001, airborne fungi were isolated from the building of the Clinical Analyses laboratories, including its didactic and research rooms, in Araraquara São Paulo State, Brazil, by using Andersen, MAS-100® (MERCK) machine, with Sabouraud chloramphenicol medium. After 5 days of incubation at 25°C, the colonies of the fungi were counted, resulting in the identification of 21 taxa. Cladophialophora spp. was the most isolated in internal and external environments as well, followed by Penicillium spp. and Mycelia spp. In accordance with the resolution n° 9, January 2003 (ANVISA), fungi considered unacceptable were found in nine internal environments and one of these presented the amount of fungi above of the acceptable limit. Among the obtained fungi, at least 16 taxa were reported as opportunistic, nine were related to plant diseases and seven were associated to allergy problems.

Epidemiologia das dermatofitoses em instituições públicas da região de Araraquara - SP

Dermatophytosis on skin, hair and nails are the most common infectious process in the world. A total of 94 individuals from Public Institutions from the city of Araraquara - Sao Paulo/Brazil, with suspected of dermatophytic lesions were examined in order to determine the incidence and etiology of dermatophytosis. 105 specimens were collected from August to December of 2001 in the Mycology Laboratory of the Faculdade de Ciências Farmacêuticas. It was observed that 47 samples were positive for dermatophytes. Trichophyton rubrum was the prevalent specie (59.6%), followed by Microsporum canis (17%), T. tonsurans (10.6%), T. mentagrophytes (8.5%) and Epidermophyton floccosum (4.3%). T. rubrum was the most frequent in interdigital lesions (81.5%) and M. canis was the main dermatophyte involved in scalp lesions (58.3%). Therefore, it was observed a predominance of antropophilic and zoophilic species, respectively. These results are in agreement with statistical data from South and Southeast regions of Brazil, as well as from other parts of the world in which these fungi were the most frequently isolates from tinea pedis and tinea capitis. In this study, it was also observed a high percentage of T. tonsurans (41.7%) in tinea capitis and this result was different from the statistical data collected until now in our region.
