adhesion of symbiont to host cell adhesion of symbiont spore to host adhesion of symbiont spore to host during symbiotic interaction GO:0075004 biological_process The attachment of a spore of the symbiont to its host via adhesion molecules, general stickiness etc. The host is defined as the larger of the organisms involved in a symbiotic interaction. Note that this term should not be used to annotate gene products of the host. It should only be used to annotate those gene products from the symbiont involved in this process.
