obsolete active evasion of symbiont immune response via regulation of symbiont complement system true OBSOLETE. Any mechanism of active immune avoidance which works by regulating the symbiont complement system, e.g. by possessing complement receptors which mediate attachment to, then infection of, symbiont macrophages, which are eventually destroyed. The symbiont is defined as the smaller of the organisms involved in a symbiotic interaction. This term was made obsolete because it does not represent a real process that exists in nature. active immune evasion via modulation of symbiont complement system biological_process GO:0051847 active immune evasion via regulation of symbiont complement system active evasion of symbiont immune response via regulation of symbiont complement system
