The Creeping Flesh (1973)

A scientist comes to believe that evil is a disease of the blood and that the flesh of a skeleton he has brought back from New Guinea contains it in a pure form. Convinced that his wife, a Folies Bergere dancer who went insane, manifested this evil, he is terrified that it will be passed on to their daughter. He tries to use the skeleton's blood to immunise her against this eventuality, but his attempt has anything but the desired result.

In an ancient castle, a mad scientist is trying to revive his dead daughter by an operation, but there are certain body parts he needs that he can't get. His problem is solved when a group of drunken party-goers stumble into his castle.

A doctor in Florida conducts shady experiments involving maggots and stolen body parts, which may be in preparation for a larger plot.
