Toxoplasma infection linked with neurological diseases

Toxoplasma gondii is a protozoan parasite that infects a third of the world's population. It is acquired through the consumption of undercook meat or unwashed vegetables. New research has shown that Toxoplasma leads to the disruption of glutamates, a neurotransmitter which transmits excitatory signals between neurons. Glutamate buildups are usually seen in traumatic brain injuries and can also be caused by Toxoplasma. The astrocytes which are suppose to remove the glutamate buildups become swelled during the infection and the glutamate transporters that are suppose to help remove the glutamates are not expressed properly. Weird fact about these parasites are that they can only sexually reproduce in cats.
