General Information
Term symbiont entry into host ID (Ontology) GO:0044409 (Gene Ontology)
Definition Entry of a symbiont into the body, tissues, or cells of a host organism as part of the symbiont life cycle. The host is defined as the larger of the organisms involved in a symbiotic interaction.
Also Known As "entry into host" ; "host invasion" ; "host penetration" (for all, see Synonyms field below)
