Symptoms
No. But humans are a dead end host for Toxoplasma, because it encysts in the muscles and hopes to be eaten by a cat. The cat is the definitive host, the only animal that the organism can complete its life cycle in and shed oocytes in the feces.
Causes
T. gondii has captured the imaginations of scientists and cat lovers ever since it was learned it can control the behavior of rodents. It changes their brains so they lose their innate fear of the smell of cat urine. In fact, it precisely alters their fear reaction so that they love the smell of cat pee.

What is the best treatment for toxoplasmosis?
Currently recommended treatment drugs for toxoplasmosis target the tachyzoite stage of the parasite and do not eradicate encysted parasites in the tissues. Pyrimethamine, considered the most effective drug against toxoplasmosis, is a standard component of therapy. Pyrimethamine is a folic acid antagonist and can cause dose-related suppression of the bone marrow, which is mitigated by concurrent administration of folinic acid (leucovorin). Leucovorin protects the bone marrow from the toxic effects of pyrimethamine. A second drug, such as sulfadiazine or clindamycin (if the patient has a hypersensitivity reaction to sulfa drugs), should also be included. The fixed combination of trimethoprim with sulfamethoxazole has been used as an alternative, as well as other drugs such as atovaquone and pyrimethamine plus azithromycin, which have not been extensively studied (see: Montoya JG, Boothroyd JC, Kovacs JA. Toxoplasma gondii in Mandell, Douglas, and Bennett’s Principles and Practice of Infectious Diseases, 8th, Edition, 2017 Mandell GL, Bennett JE, Dolin R, Eds. Churchill Livingstone Elsevier, Philadelphia, PA.)

What is the best treatment for toxoplasmosis?
The folate pathway, involved in DNA synthesis with the dihydrofolate reductase (DHFR) and dihydropteroate synthetase (DHPS) enzymes, is the main target of anti-Toxoplasmadrugs. Pyrimethamine (PYR) and trimethoprime (TMP), two major drugs in the treatment of acute toxoplasmosis, both act on parasite DHFR, but are unable to distinguish it from the enzyme of the human host. Taken alone, they are not enough powerful, thus they must be associated in combination regimens with sulfonamides which block DHPS. Therefore, current treatment regimens have side effects due to myelotoxicity (not to mention more severe ones that can be life-threatening), and require discontinuation of therapy, or, more frequently, induce lack of compliance. This is a serious drawback, as patients (congenitally infected neonates, immunocompromised patients) usually need prolonged courses of treatment. Most of all, no current drug is able to eliminate T. gondiicysts from the infected host, which remain quiescent, provided that the immune system is strong enough to hamper their reactivation into tachyzoites.
Where is the National Reference Laboratory for Toxoplasmosis located?

Is spiramycin good for MFTP?
Women infected during pregnancy (or around conception) are generally offered spiramycin (SPI), a potent macrolide antibiotic that concentrates in the placenta, making it an ideal preliminary treatment option for the prevention of MFTP (Table 1). Due to the low rate of adverse effects, SPI is a comfortable treatment option while awaiting amniocentesis. Unfortunately, SPI is ineffective for the treatment of an established fetal infection, since it barely crosses the placental barrier (Robert-Gangneux et al., 2011).
Is T. gondiiis drug resistant?
Drug resistance in T. gondiiis considered to be a negligible issue, compared to poor compliance and the spectrum of adverse events. However, failure of the long-term PYR-based treatment for congenital toxoplasmosis (CT), possibly due to the development of drug-resistant T. gondiistrain, has been reported (Villena et al., 1998). Moreover, Silva et al. have recently isolated a sulfadiazine-resistant T. gondiistrain from congenitally infected newborns in Brazil (Silva et al., 2017). Although limited by the slow multiplication of the parasite and the transmission routes of the disease, both preventing wide spread of a resistant strain, this finding shows that drug resistance development in T. gondiiis possible.
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.
