Abstract: the dispersal of airborne fungi is made through atmospherical air. knowledge of anemophilous fungi in a given city is important for the ecological diagnosis and specific treatment of allergic manifestations induced by inhaled allergens. their use in individuals' allergy is widespread, and probably will remain so in the years to come. the purpose of this research was to make a relationship between the airborne fungi and the patients' respiratory allergy (asthma and rhinitis) from the city of fortaleza, state of ceará, brazil. first a research was made in fortaleza about the fungal allergens dispersed in atmospherical air. fungal allergen extracts were made from the ten most predominant moulds in the air, using sodium bicarbonate. the prick tests were made in fifty patients with asthma and rhinitis and in ten healthy persons (with no respiratory allergy). the positive test was made using histamine and the negative test with sodium bicarbonate preparation. the predominant fungi in the air of fortaleza were: aspergillus, penicillium, curvularia, cladosporium, mycelia sterilia, fusarium, rhizopus, drechslera, absidia and alternaria. as determined by the prick test: three fungal extracts (aspergillus, alternaria and drechslera) were positive in all patients; two (penicillium and curvularia) were positive in thirty-five patients; two (cladosporium and mycelia sterilia) were positive in thirty patients; and three (rhizopus, absidia and fusarium) were positive in nine patients. all the control tests were negative. all the ten most predominant anemophilous fungi isolated in the air could provoke skin test reactivity in individuals with respiratory allergy in fortaleza.

Abstract: the possible involvement of saprobe fungi in dermatomycoses, as well as the determination of the incidence of dermatophytes in dogs and cats were studied. during a period of one year, 74 dogs and 18 cats, with cutaneous lesions suggesting mycoses were included in this study. the mycological analyses were conducted by direct microscopy and by fungal culture on sabouraud agar, chloramphenicol sabouraud agar and mycosel agar. of the 92 samples, 21 resulted in positive cultures for dermatophytes. dermatophyte fungi pure cultures were obtained from 13 samples. a simultaneous growth of dermatophytes plus saprobe fungi was observed in 8 of the samples. of the remaining 71 samples, no fungal growth was observed in 10 samples, and at minimum the growth of one saprobe fungi in 61. one, two and three genera of saprobe fungi were isolated in 29, 30 and 2 samples, respectively. microsporum canis was isolated in 6 (28.6 %) and 10 samples (47.6 %) from cats and dogs, respectively, and trichophyton mentagrophytes in 2 (9.5 %) and 3 samples (14.3 %) from cats and dogs, respectively. the following genera of saprobe fungi were also isolated: alternaria sp (1.9%), chaetomium sp (1.9%), rhizopus sp (2.9%), curvularia sp (3.9%), candida sp (6.8%), trichoderma sp (6.8%), fusarium sp (7.8%), cladosporium sp (8.7%), penicillium sp (21.4%) and aspergillus sp (37.9%).

Abstract: The aim of this study was identification of fungi in indoor and outdoor of asthmatic patients′ home environment. Opened plates (containing of Malt extract agar media) were used for isolation of fungi in the air of indoor (n=360) and outdoor (n=180) of 90 asthmatic patients home living in the city of Sari at the level of breathing height. Plates were incubated in room temperature for 7-14 days. Then grown fungi were identified by standard mycological techniques. A total of 1876 colonies with 31 and 1692 colonies with 27 genera of fungi were identified from indoor and outdoor of asthmatic patients’ home respectively. The most common fungi isolated were Cladosporium, Aspergillus and Penicillium. Stachibotyris, Oedocephalum, and Stemphillium showed the least frequencies among the isolated fungi. Cladosporium, Aspergillus, Penicillium, and Alternaria as the most common allergenic moulds had the most frequencies in indoor air of the houses of asthmatic patients.

Abstract: Se llevó a cabo una investigación sobre los hongos presentes cn la atmósfera de la Ciudad de México, a través del análisis del agua dc lluvia colectada durante los meses de junio a septiembre de 1982. Para lograr el aislamiento de una amplia gama de hongos se utilizaron los medios de Sabouraud dextrosa agar y papa dextrosa agar, incubados a temperatura ambiente (20-26vC) por 48-72 h. Durante cl muestre0 se registraron entre 600 y 6000 colonias por ml. Los hongos que aparecieron con más frecuencia fueron Cladosporium, Alternaria, Penicillium y levaduras. Se estableció la relación que existe entre la abundancia de estos organismos e11 cl airc y los factores ambientales. Se observó que la velocidad del viento cstuvo relacionada con la abundancia de los hongos en el agua de lluvia con una r de 0.80 (p < 0.01). La identificación de algunas colonias a nivel de especie, tales como Penicillium citrinum, P. clauigerurn, Fusarium semitectum, Asfiergillus niger, A. candidus, A. glaucus y A. tarnarii, permitió se alar la presencia de hongos patógenos o alergenos. Esta información puede servir de base para estudios futuros sobre la implicación de los factores ambientalcs en la abundancia y dispersión dc hongos importantes para los sectores médico y agrícola.

Abstract: knowledge of anemophilous fungi in a given city or region is important for the ecological diagnosis and specific treatment of allergic manifestations induced by inhaled allergens. in order to diagnose the presence of anemophilous fungi, several qualitative and quantitative techniques are used depending on the study place. this study of fungal air spores was performed with a rotorod sampler?, an equipment which samples the air through a plastic rod attached to an electric engine that makes it spin fast enough to collect the particles in the air. the samples were collected once a week during 24 hours using the standard cycle of the manufacturers. a total of 52 samples were obtained from april 2000 through march 2001. the results revealed prevalence of ascosporos (50.49%), cladosporium (17.86%), aspergillus/penicillium (15.03%), basidiosporos (3.84%), rusts (3.82%), and helminthosporium (2.49%), and a lesser frequency of botrytis (1.22%), alternaria (1.19%), smuts (0.90%), curvularia (0.87%), nigrospora (0.61%), and fusarium (0.08%). also, 1.59% of the spores detected here could not be identified by the systematic key used. more fungal spores were observed during the summer than during the autumn.

Journal of Applied Sciences , 2007,
Abstract: In this study, soil samples for isolation of heavy metal resistance fungi were collected from different distance of Electric Meter manufactory in Second Industrial City, Riyadh, Saudi Arabia. Soil samples were analyzed chemically for heavy metal concentrations, total soluble salts and pH and mechanically for composition of soils. Saturation percent were determined also. Eighteen fungal isolates were grown in 10 mM concentration of either lead or copper ions. Aspergillus was predominant and represented by 6 species. Fusarium was represented by 4 species. Mucor was represented by 3 species. Penicillium was represented by 2 species. While Alternaria, Cephaliophora, Eurotium were represented by one species each. The intraspecific variability in growth response to Pb2+ and Cu2+ on agar and liquid culture was studied among isolated fungi. The growth rate of some fungi isolated on solid media was less sensitive to addition of lead or copper than biomass production in liquid culture.

Abstract: Twenty soil samples from Eastren, Westren, Northen an Southern directions of Gold and Silver manufactory in second industrial city, Riyadh, Saudia Arabia were collected and analyzed chemically for heavy metal concentrations, total solubal salts and pH and mechanically for composition of soils. Saturation percent were determined also. From soil samples collected thirteen fungal isolates were able to grew in media containing 10 mM of either aluminium or cobalt ions. Aspergillus were predominant and represented by four species. Fusarium and Penicillium were represented by 3 species. While Auerobasidium, Mucor and Monascus were represented by one species each. Intraspecific variability in growth response to Al3+ and Co2+ on agar media was studied among isolated fungi.
