1. The state of being free from contamination by, or associated with any other living organism: Axeny is usually used in reference to pure cultures of microorganisms that are completely free of the presence of other organisms.
2. The situation of experimental animals that are raised under sterile conditions: Axeny is the condition, normally in animal research, in a germ free and sanitized environment.

dixenic, dixenous (adjective) (not comparable))
In biology and parasitology, a mixed culture of one organism together with two other species: Linda read that a dixenic parasite's development takes place between two different kinds of hosts to complete its life cycle.
