Toxoplasmosis is a common infectious disease in cats. It is found in almost 300 species of mammals and in about 60 species of birds. It does not spare a person either. Up to half of the world's population is infected with toxoplasmosis. In the United States, 23% of the population are native speakers, in Russia - about 20%, and in some parts of the world the share of speakers reaches 95%.

It usually proceeds chronically, sometimes acutely, characterized by a complex of nervous phenomena, as well as pathology of pregnancy and childbirth. The causative agent of the disease is the simplest unicellular, parasitic in tissues, Toxoplasma gondii. For a long time, the dog was considered the main source of infection. However, recent studies have proven the leading role of cats in the life cycle of the pathogen.

The cat is the final (definitive) host of the parasite, since only in the small part of its intestine can sexual reproduction of the causative agent of toxoplasmosis occur. With feces, the pathogen enters the external environment and under favorable conditions for a long time (up to 17 months) retains its ability to become infected.

In other animals (and in humans), Toxoplasma multiplies in the cells of various tissues only through repeated division (asexual reproduction) and is practically not released into the external environment, but form in the muscles a cluster of parasites enclosed in a dense shell, which can be in the tissues for years.

Most often, Toxoplasma infection occurs through contaminated feed. The latent (incubation) period ranges from several days to several weeks. The acute course of the disease in cats is rare and occurs mainly in young animals. In this case, various uncharacteristic symptoms are observed. Drooling, runny nose, coughing and rapid breathing are indicative of a respiratory illness. Vomiting and diarrhea that is difficult to stop raise suspicion of panleukopenia. Paralysis, convulsions indicate damage to the central nervous system.

The chronic course of the disease is characterized by emaciation, paresis of the limbs, miscarriages and the birth of freaks are possible in pregnant animals. The latent course of the disease is characteristic of cats.

The diagnosis of toxoplasmosis is made on the basis of comprehensive laboratory tests of blood and feces. Antibiotics are not effective in treating toxoplasmosis. Certain drugs are used, for example, chloridine (daraprim), in combination with sulfodemizine, sulfadimethoxine, and chemicalcide. For disinfection, you can use a 1.5-2% chloramine solution.

An effective preventive measure is daily thorough cleaning of the litter box and rinsing it with boiling water. The following rules must be followed: examine cats for toxoplasmosis; not to allow close contact of children and pregnant women with cats; wash your hands thoroughly after interacting with cats and handling raw meat; thorough destruction of cat feces; cats should not be kept in rooms where food is stored; stubborn fight against rodents in food warehouses.

Human toxoplasmosis. With toxoplasmosis, the brain, visual organs are primarily affected, and then the internal organs, lymph nodes and skin.

Congenital toxoplasmosis can be acute or chronic. Acute toxoplasmosis is usually accompanied by fever, headache, and muscle pain.

Chronic toxoplasmosis can take years. It is characterized by a slight fever, weakness, headaches, irritability, decreased vision, memory and performance, enlarged liver, spleen, and lymph nodes. Frequent myocardium, pneumonia. Only laboratory tests can determine the cause of the disease.
