On Argelius II a non-corporeal entity that fed on fear assumed the form of one of the planet's inhabitants. It was later discovered the same entity had taken the form of "Jack the Ripper" in Terran history. The entity traveled between planets taking over host humanoid bodies. The entity then used the host body to murder women to feed on their fear. The entity took complete control of the body, making it harmful and the host was no longer conscious of its surroundings. (TOS: "Wolf in the Fold")
The neural parasites that invaded Starfleet Command were another type of parasite. Officers of Starfleet were taken over by neural parasites that attached themselves to the spinal cord and brain of the host. The host was left unable to control his own actions, and in the case of the Queen parasite, the host's body was left destroyed when the Queen exited. (TNG: "Conspiracy")
In 2377, B'Elanna Torres fainted while in engineering. Icheb scanned her with a medical tricorder and detected a lifeform inside her. He quickly believed it to be a parasite. Seven of Nine then did her own scan and found she was actually pregnant with her first child. (VOY: "Lineage")
