Airborne fungi isolated from rain water collected in Mexico City

Resumen

Español
A rcsearch was carried out on the lungi present in tlir atmosphere of Mexico City, through the analysis of rain watcr collected from June to Septcmber of 1982. To obtain data ori a wide range oí fungi, isolations were made on Sabouraud dextrosc agar and potatc) dcxtrosc agar plates incubated at the rnom tcmperaturc of 20-26QC for 48- 72 hours. During tlic sampling period 600 to GOOO colonies per m1 were rccorded. The most frequent fungi were Cladosporium, Alternaria, Penicillium and yeasts. The relationship between these airborne organisms and weather elements was established. It was found that wind speed was related to fungal counts through a corrclation coefficient of r = 0.80 (p < 0.01). Identification at thc species leve1 of some fungi, such as Penicillium citrinum, P. clavigerurn, Fusarium semitectum, Aspergillus niger, A. candidus, A. glaucus and A. tamarii, allowed to show the presence of both pathogenic and allergenic fungi. This infonnation could be used in further studies of a medical or agronomical character about. the effect of environmental factors on the abundance and dispersion of airborne fungi.
