A new parasite called Toxoplasma
Gondi has been discovered. This parasite has infected eleven percent of all
Americans and half of the world’s population. Toxoplasma has the ability to
alter behavior and cause the host to commit dangerous tasks. Toxoplasma was
found to have the ability to turn the host’s genes on and off. However,
Toxoplasma can only reproduce in cats. Once Toxoplasma produces cysts inside of
the cat, the cysts enter the soil through the cat’s feces. Some animals are
afraid of cats, such as mice. However, mice are not aware of the cat’s presence
after being infected with toxoplasma. This parasite has the ability to take
over a host’s nervous system and render it useless. After being infected, a
host will begin to produce excess amounts of arginine vasopressin, a
neurotransmitter. Scientists believed that they could be able to reverse this
process and make a prey further aware of the predator. In order to test this
theory, scientists used mice and injected them with molecular caps. The molecular
caps would counteract toxoplasma and increase awareness of surroundings.
However, this injection is in progression and has functioned properly.
Scientists need to be aware of the
new threats that are spreading across the world. Through research and testing,
we will be able to understand how this parasite affects the inner workings of
our body. Scientists will soon be able to develop a remedy, which will help a
host fight against Toxoplasma. However, this parasite is newly discovered and
seems to be a form of pathogen. Scientists understand that no one wants to be controlled. They will work as hard as they can in order to guarantee that every host has control over themselves.
