Toxoplasmosis is an infection caused by the parasite Toxoplasma gondii, a microscopic single-cell organism that can be found in meat, cat faeces, the soil where cats defecate and unpasteurised goats’ milk.T. gondii is ubiquitous in birds and mammals. This obligate intracellular parasite invades and multiplies asexually as tachyzoites within the cytoplasm of any nucleated cell. When host immunity develops, multiplication of tachyzoites ceases and tissue cysts form; cysts persist in a dormant state for years, especially in brain and muscle.
Most cases of toxoplasmosis are mild and don't require treatment. Either no symptoms develop, or a full recovery is made without complications. If needed Most people will be treated with a combination of medicines called pyrimethamine, sulfadiazine and folinic acid. These medications usually need to be taken for at least four to six weeks.In the Norway, about 1,599,602 cases of Toxoplasmosis infection are reported in humans each year. Almost 12% of the Norway population is infected with Toxoplasmosis, a parasite of dogs and cats that can be passed from animals to humans.
