Sexual Reproduction. As compared to asexual reproduction, sexual reproduction of Toxoplasma gondii occurs within the definitive host. This cycle can be said to start when the host (wild or domestic cat) ingests oocysts/tissue infected with bradyzoite cysts.
Is toxoplasmosis asymptomatic?
For the most part, toxoplasmosis (the infection caused by Toxoplasma gondii) remains asymptomatic in healthy human beings. This is largely due to the fact that the body’s' immune system is able to control the parasite thus preventing the infection from getting out of control.
How to prevent toxoplasma?
To help prevent toxoplasma infection, it is essential to thoroughly wash your hands after handling cat litter, soil, or raw meat. Avoid eating food possibly contaminated with cat feces. It is also extremely important to cook food at safe temperatures. Make sure to use a food thermometer to measure your cooked meat’s internal temperature. The following are some prevention guidelines against toxoplasmosis: 1 Cook whole cuts of meat at a minimum of 145 degrees Fahrenheit, and allow for three minutes of rest time before consumption. Ground meat should be cooked at 160 degrees Fahrenheit, and no rest time is required. 2 The cooking temperature exception is poultry, which should be cooked at least 165 degrees Fahrenheit. Three minutes of rest time is also required. 3 Chance of infection is significantly reduced from freezing meat for several days at sub-zero temperatures. 4 Wash or peel fruits and vegetables thoroughly before consumption. 5 After coming in contact with raw poultry, meat, seafood, or unwashed vegetables and fruit, always wash counters, utensils, dishes, and cutting boards. 6 Oysters, mussels, or clams should not be eaten raw, since they may be contaminated with Toxoplasma from seawater. 7 Always wear gloves when gardening or contacting soil or sand. Afterwards, hands should be washed with warm water and soap.

What is the disease caused by Toxoplasma gondii?
Toxoplasmosis is a parasitic disease caused by Toxoplasma gondii, an apicomplexan. Infections with toxoplasmosis usually cause no obvious symptoms in adults. Occasionally, people may have a few weeks or months of mild, flu-like illness such as muscle aches and tender lymph nodes.
How is toxoplasmosis spread?
Toxoplasmosis is usually spread by eating poorly cooked food that contains cysts, exposure to infected cat feces, and from an infected mother to her baby during pregnancy . Rarely, the disease may be spread by blood transfusion. It is not otherwise spread between people.
Where are trophozoites found?
The toxoplasmic trophozoites causing acute toxoplasmosis are referred to as tachyzoites, and are typically found in various tissues and body fluids, but rarely in blood or cerebrospinal fluid. Swollen lymph nodes are commonly found in the neck or under the chin, followed by the armpits and the groin.
What is the condition of a baby with a positive antibody?
Congenital toxoplasmosis is a specific form of toxoplasmosis in which an unborn fetus is infected via the placenta. Congenital toxoplasmosis is associated with fetal death and miscarriage, and in infants, it is associated with neurologic deficits, neurocognitive deficits, and chorioretinitis. A positive antibody titer indicates previous exposure and immunity, and largely ensures the unborn fetus' safety. A simple blood draw at the first prenatal doctor visit can determine whether or not a woman has had previous exposure and therefore whether or not she is at risk. If a woman receives her first exposure to T. gondii while pregnant, the fetus is at particular risk.
Can you get T. gondii without knowing?
Due to the absence of obvious symptoms, hosts easily become infected with T. gondii and develop toxoplasmosis without knowing it. Although mild, flu-like symptoms occasionally occur during the first few weeks following exposure, infection with T. gondii produces no readily observable symptoms in healthy human adults. In most immunocompetent people, the infection enters a latent phase, during which only bradyzoites ( in tissue cysts) are present; these tissue cysts and even lesions can occur in the retinas, alveolar lining of the lungs (where an acute infection may mimic a Pneumocystis jirovecii infection), heart, skeletal muscle, and the central nervous system (CNS), including the brain. Cysts form in the CNS ( brain tissue) upon infection with T. gondii and persist for the lifetime of the host. Most infants who are infected while in the womb have no symptoms at birth, but may develop symptoms later in life.
Does T. gondii cause schizophrenia?
Some evidence links T. gondii to schizophrenia. Two 2012 meta-analyses found that the rates of antibodies to T. gondii in people with schizophrenia were 2.7 times higher than in controls. T. gondii antibody positivity was therefore considered an intermediate risk factor in relation to other known risk factors. Cautions noted include that the antibody tests do not detect toxoplasmosis directly, most people with schizophrenia do not have antibodies for toxoplasmosis, and publication bias might exist. While the majority of these studies tested people already diagnosed with schizophrenia for T. gondii antibodies, associations between T. gondii and schizophrenia have been found prior to the onset of schizophrenia symptoms. Sex differences in the age of schizophrenia onset may be explained in part by a second peak of T. gondii infection incidence during ages 25–30 in females only. Although a mechanism supporting the association between schizophrenia and T. gondii infection is unclear, studies have investigated a molecular basis of this correlation. Antipsychotic drugs used in schizophrenia appear to inhibit the replication of T. gondii tachyzoites in cell culture. Supposing a causal link exists between T. gondii and schizophrenia, studies have yet to determine why only some individuals with latent toxoplasmosis develop schizophrenia; some plausible explanations include differing genetic susceptibility, parasite strain differences, and differences in the route of the acquired T. gondii infection.

Tachyzoites
- As compared to asexual reproduction, sexual reproduction of Toxoplasma gondii occurs within the definitive host. This cycle can be said to start when the host (wild or domestic cat) ingests oocysts/tissue infected with bradyzoite cysts. Once they are ingested, the cyst wall is dissolved by proteolytic enzymes in the stomach and small intestine to release bradyzoites. The free bradyzo…
Bradyzoites
- Whereas sexual reproduction cycle only involves the definitive host (wild/domestic host), asexual reproduction requires both the definitive and intermediate hosts. To describe this type of reproduction, we can assume that it starts with the release of the oocysts into the environment. Typically, the oocysts released into the environment along with fecal matter (by the definitive ho…
Sporozoites
- Before penetrating the cell, the parasite first has to attach to the surface of the host cell. In order to do this, the parasite relies on receptor-ligand interactions to overcome the repulsive force caused by the net negative charge of both the parasite and host cell membrane. As compared to many other parasites, Toxoplasma gondii are capable of attaching and penetrating many differe…
