In the natural world exist many parasites who specialized in hypnosis and replacing host. A recent study published in the Journal of the Royal Society has pointed out the existence of the parasite "cannibalism". Accordingly, the parasite after entering the host, directly controlling behavior and making the hosts eat their fellows.
Mandy Bunke Leeds University and her research team points out that both parasite and cannibalism existed about 3,000 species, are present everywhere in nature.
In this study, experts have focused on understanding celticus duebeni Gammarus shrimp species live in the waters off Ireland in County Antrim or Downhill River (Northern Ireland) and tiny parasites Pleistophora mulleri.
Researchers tracked the interactions between parasites and shrimp Gammarus Pleistophora mulleri duebeni celticus. They found, invading parasites, feeding nutrients from its host and raised.

Mandy Bunke explained that every parasite is very small in size, but only about 5 micrometers can reproduce and spread to millions of shrimp hosts quickly.
Once a body enters the shrimp, they will destroy muscle shrimp, shrimp suck nutrients that are always in a state of hunger and then gradually dominate the behavior of its host. At this point, the parasite infected shrimp will look to fellow - creatures smaller shrimp to eat.
Alison Dunn from the University of Leeds, said: "Perhaps the only way to cannibalism are paying smaller shrimp infected shrimp can survive."
Experts said that, we can this parasitic infection after consuming food infected shrimp. However, studies have not found out whether human behavior has not cannibals or after infection with this parasite.
Another study by scientists Glen McConkey showed that 10-20% of the UK population are infected with the parasite Toxoplasma gondii - it directly affects the production of dopamine - an important chemical in the brain.
A lot of evidence that, Toxoplasma gondii invade the central nervous system of humans, cause health problems such as schizophrenia disease, functional neurosis and brain cancer.
Mark Torchin of the Smithsonian Tropical Research Institute told Discovery News that: "Some parasites have been proven to be capable of strongly altering the host. This finding will help us have better new look tiny parasite, but extremely dangerous. "
