Abstract

13 strains of imperfect fungi have been studied in Lyon according to a biochemical criteria or growth of the studied species in a minimum but nitrogenous medium containing carbon elements. The inoculation is achieved by Api System ensemencement. The germination of the spores showing the carbon assimilation involves the appearance of a trouble. The intensity of this growth is coded by + or −.

The table of the characteristics for the various strains is studied thanks to a taxonomic method based on a relation of proximity by the Euclidean distance. Every strain is represented mathematically by a point in the characteristics-space. The strains are gathered into classes with regard to their proximity, every class being characterized by its centre of gravity. The similar characteristics are studied thanks to a classification tree or dendrogram.

The programme has regrouped the two species pathogenic fungi on the one hand and the ten strains taken in the atmosphere on the other hand, the telluric one having to be set apart.
