Is Toxoplasma gondii a virus?

Toxoplasma gondii is a protozoan parasite that infects most species of warm-blooded animals, including humans, and causes the disease toxoplasmosis.

What type of disease is toxoplasmosis?

Toxoplasmosis (tok-so-plaz-MOE-sis) is a disease that results from infection with the Toxoplasma gondii parasite, one of the world’s most common parasites. Infection usually occurs by eating undercooked contaminated meat, exposure from infected cat feces, or mother-to-child transmission during pregnancy.

Is Toxoplasma a coccidia?

Toxoplasma gondii and Eimeria spp. are widely prevalent Coccidian parasites that undergo sexual reproduction during their life cycle.

How do humans get toxoplasmosis?

Eating undercooked, contaminated meat (especially pork, lamb, and venison) or shellfish (for example, oysters, clams or mussels). Accidental ingestion of undercooked, contaminated meat or shellfish after handling them and not washing hands thoroughly (Toxoplasma cannot be absorbed through intact skin).

What is toxoplasmosis of the brain?

Cerebral toxoplasmosis is usually caused by reactivation of the latent cystic form of T. gondii in the central nervous system (CNS) and it as a major cause of morbidity and mortality among human immunodeficiency virus (HIV) infected patients, particularly in developing countries.

Where is toxoplasmosis found in the body?

Toxoplasma gondii has been found in the kidneys, bladder and intestine of infected humans. There have been rare cases of organ transplant recipients acquiring toxoplasmosis infection. Contaminated human urine and feces could possibly be a source of infection but transmission from this source has not been proved.

What are the signs of toxoplasmosis in humans?

Symptoms of toxoplasmosis Swollen lymph glands, especially around the neck. Muscle aches and pains. Headache. Fever.

How does toxoplasmosis affect the brain?

Scientists have shown how the toxoplasmosis parasite hides away in the brain, altering synapses and potentially causing depression, schizophrenia and autism. Mice infected with toxoplasmosis parasites behave strangely: They lose their natural fear of cats.

Can toxoplasmosis be cured?

Many congenital toxoplasmosis cases can be cured with medications. Even children who had severe infections at birth may never show signs of severe long-term damage if they are diagnosed and treated early. Delays in diagnosis and treatment can contribute to a poor prognosis.

What does toxoplasmosis do to the brain?

A research group from the University of Leeds has shown that infection by the brain parasite Toxoplasma gondii, found in 10-20 percent of the UK’s population, directly affects the production of dopamine, a key chemical messenger in the brain.

Can toxoplasmosis cause mental illness?

Infection by the parasite Toxoplasma, which affects about 33% of world population, is associated with an increased risk of several mental health disorders, the most strongly with schizophrenia.

How is toxoplasmosis diagnosed?

The diagnosis of toxoplasmosis is typically made by serologic testing. A test that measures immunoglobulin G (IgG) is used to determine if a person has been infected.

Who is most at risk for toxoplasmosis?

The Centers for Disease Control and Prevention (CDC) estimates that over 40 million people in the United States may have the parasite. Of those with the parasite, the people most at risk of serious illness are people with weakened immune systems and babies born to parents with toxoplasmosis.

Does Toxoplasma go away?

Does toxoplasmosis go away? For most people, toxoplasmosis will go away without treatment after a few weeks or months. But those people requiring treatment may need to stay on medication for weeks or months for the infection to clear.

What causes coccidiosis?

Causes. Coccidiosis is caused by protozoan parasites of the genus Eimeria. These are obligated intracellular parasites with complex life cycles including sexual and asexual stages.

Is malaria a coccidia?

Plasmodium, a genus of parasitic protozoans of the sporozoan subclass Coccidia that are the causative organisms of malaria. Plasmodium, which infects red blood cells in mammals (including humans), birds, and reptiles, occurs worldwide, especially in tropical and temperate zones.

Is coccidiosis viral or bacterial?

Coccidiosis is a parasitic disease of the intestinal tract of animals caused by coccidian protozoa. The disease spreads from one animal to another by contact with infected feces or ingestion of infected tissue. Diarrhea, which may become bloody in severe cases, is the primary symptom.
