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(R), 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.
了解特定城市或地区的风媒真菌,对于由吸入性变应原引起的过敏表现的生态诊断和特异性治疗非常重要。为了诊断风媒真菌的存在,根据研究地点的不同,会使用多种定性和定量技术。本研究使用旋转杆采样器(R)对真菌空气孢子进行采样,该设备通过连接到电动发动机的塑料杆对空气进行采样,电动发动机使塑料杆快速旋转以收集空气中的颗粒。使用制造商的标准周期,每周采集一次样本,每次采集24小时。从2000年4月至2001年3月共获得52个样本。结果显示,子囊孢子的患病率为50.49%,枝孢属为17.86%,曲霉属/青霉属为15.03%,担子孢子为3.84%,锈菌为3.82%,长蠕孢属为2.49%,而葡萄孢属(1.22%)、链格孢属(1.19%)、黑粉菌(0.90%)、弯孢属(0.87%)、黑孢霉属(0.61%)和镰刀菌属(0.08%)的出现频率较低。此外,此处检测到的1.59%的孢子无法通过所使用的分类检索表进行鉴定。夏季观察到的真菌孢子比秋季更多。
