Toxoplasma gondii is an obligate intracellular parasitic protozoan (specifically an apicomplexan) that causes toxoplasmosis.
Toxoplasmosis may cause flu-like symptoms in some people, but most people affected never develop signs and symptoms.
Some people, however, develop signs and symptoms similar to those of the flu, including:
Body aches
Swollen lymph nodes
Headache
Fever
Fatigue
Confusion
Poor coordination
Seizures
Lung problems that may resemble tuberculosis or Pneumocystis jiroveci pneumonia, a common opportunistic infection that occurs in people with AIDS
Blurred vision caused by severe inflammation of your retina.
