Coulomb's law and Newton's law of universal gravitation are based on action at a distance. Historically, action at a distance was the earliest scientific model for gravity and electricity and it continues to be useful in many practical cases.
Experiments have involved a wide range of parasites, diseases, and hosts. The effects on humans have been of special interest. The effects on humans have been of special interest. The tendency of many parasitic worms to pacify the host's immune response allows them to mollify some diseases, while worsening others.
Coulomb's inverse-square law, or simply Coulomb's law, is an experimental law [1] of physics that calculates the amount of force between two electrically charged particles at rest. This electric force is conventionally called the electrostatic force or Coulomb force . [ 2 ]
Coulomb's law states that: [5] The magnitude of the electrostatic force of attraction or repulsion between two point charges is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them. The force is along the straight line joining them.
Nematomorpha (sometimes called Gordiacea, and commonly known as horsehair worms, hairsnakes, [1] [2] [3] or Gordian worms) are a phylum of parasitoid animals superficially similar to nematode worms in morphology, hence the name. Most species range in size from 50 to 100 millimetres (2.0 to 3.9 in), reaching 2 metres (79 in) in extreme cases ...

Many of the worms referred to as helminths are intestinal parasites. An infection by a helminth is known as helminthiasis, helminth infection, or intestinal worm infection. There is a naming convention which applies to all helminths: the ending "-asis" (or in veterinary science: "-osis") is added at the end of the name of the worm to denote the ...
The more common approach for parasites is to indirectly induce behavioral responses by interacting with the host's immune system [8] to create the necessary neuroactive compounds to induce a desired behavioral response. [9] Parasites can also indirectly affect the behavior of their hosts by disturbing their metabolism, development, or immunity. [9]
