[Fungal spores in the atmosphere at Besançon, France: seasonal and annual variations during 1988 and 1989]. / Les spores fungiques dans l'atmosphère de Besançon, France: variations saisonnières et annuelles au cours des années 1988 et 1989.

Airborne spora in the atmosphere of Besançon were weekly determined, searching links between appearance of species and seasonal allergies. By comparison of the results of the two years, it is easy to see many variations. At first, the number of colonies collected is very different, 2,990 colonies in 1988, 9,841 in 1989. During 1989, some genera are present in greatest quantities. It is the case of Cladosporium and Epicoccum in summer and Aspergillus in autumn. For the allergologists, Alternaria, very abundant during 1989, is perhaps the outstanding incident, this genus being considerated as very allergenic.
