Division 3 Biological agents which have not been classified for inclusion in groups 2 to 4 of the list are not implicitly classified in group 1.F1

For genera where more than one species is known to be pathogenic to man, the list will include those species which are known to be the most frequently responsible for diseases, together with a more general reference to the fact that other species of the same genus may affect health.

When a whole genus is mentioned in the classified list of biological agents, it is implicit that the species and strains known to be non-pathogenic are excluded.
