The only roundworms that have a symbiotic relationship with humans live in our digestive tracts. They absorb nutrients and release toxic waste without giving us any benefit. Thus, roundworms have a parasitic relationship with humans. Technically parasitism (one organism benefits, the other is harmed) is considered a different form of interaction between species as symbiosis (both organisms benefited). The other possibility is commensalism (one organism benefits, the other is not affected).
