When different toxins are produced on the same host, but these toxins affect different host species, the term pathotype should be used in addition. All isolates which are not confined to specific hosts and / or toxins should retain only the binomial name until such specificity is found."
If multiple poisons are produced by a single host affecting various host types, then the term pathotype must be applied alongside them. Isolates without defined host or toxin restrictions should retain their binomial names until specific characteristics are identified.
