Toxoplasmosis in cats
Toxoplasmosis in cats
Toxoplasma gondii (Toxoplasmosis) in just comb toe mouse spleen mononuclear cells discovered by the French scholar in 1980, belongs to the native biological taxonomy - Apicomplexan - coccidiosis Gang - coccidiosis Head - Sarcocystis Branch - Toxoplasma, body arched, full name Toxoplasma gondii (Toxoplasma gondii). Toxoplasma gondii belongs to opportunistic pathogenic protozoa. When the body's immune function is normal, toxoplasma infection usually does not show obvious clinical symptoms.
Ways of infection of Toxoplasma gondii:
The intermediate host or the terminal host ingests foods containing infected worms (including tachyzoites, bradyzoites, and mature oocysts), including untreated meat products, dairy products, egg products, and drinking water.
Studies have shown that with a very small probability, Toxoplasma gondii can be infected through the mouth, nose, eye conjunctiva, or broken skin or mucous membrane; flies, cockroaches, earthworms, etc. can be used as media for the transmission of Toxoplasma oocysts; arthropods carry oocysts also The meaning of communication.
Clinical manifestations of Toxoplasma gondii:
Whether it develops after infection with Toxoplasma gondii depends on factors such as the virulence of the strain, the number of infections, the route of infection, and the immunity of the host. Cats are poorly sensitive to Toxoplasma gondii, only a few will have clinical symptoms, and the damage to the body is very limited.
The worm strains infected by the host are very virulent and fail to produce sufficient immunity.
The host immune function is weak, and the bradyzoites of Toxoplasma gondii in the body may become tachyzoites with vigorous metabolism and rapid proliferation
In cats infected with toxoplasma gondii, the clinical symptoms are mostly related to the central nervous system, visual, respiratory and gastrointestinal systems, including fever, jaundice, shortness of breath, cough, anemia, muscle pain, dyskinesia, hind limb paralysis, etc., and there are also cases of encephalitis, premature birth or abortion.
How to keep cats away from Toxoplasma gondii?
Cats are both the intermediate host and the final host of Toxoplasma gondii. Therefore, in terms of prevention, it is necessary to consider both the prevention of the cat itself and the prevention of people living together or other susceptible animals (such as dogs).
Prevent environmental infections
1. Do not drink untreated raw water/tap water directly;
2. Wear gloves when touching the outside soil, sand or cat litter box, and wash your hands with soap and warm water after touching;
3. Inform children of the importance of hand washing;
4. Feed the cat's finished dry food, wet food, or fully cooked/frozen homemade food, avoid directly feeding raw or semi-cooked meat;
5. For cats with confirmed or suspected infection of Toxoplasma gondii, the litter should be cleaned and replaced every day to prevent the oocysts in the litter box from becoming infectious oocysts.
If the family has pregnant women or immunosuppressed people
1. Avoid cleaning and replacing cat litter yourself. If it is unavoidable, wear disposable gloves when handling, and wash your hands with soap and warm water after handling.
2. Cats are kept indoors completely to avoid preying on possible intermediate hosts or insect-preserving hosts such as mice and earthworms.
3. Do not adopt or come into contact with stray cats (especially kittens) whose infection status is unknown, and do not raise new cats during pregnancy.
Whether for cats, humans or other animals, food-borne infection is the main way of toxoplasma infection, and food hygiene should be paid attention to daily. Humans or other animals interacting with cats have a very low probability of infection. If the cat itself is not infected with Toxoplasma gondii, it is impossible to talk about it. Develop good hygiene habits and prevent diseases from entering the mouth. This is to avoid toxoplasma infection. The best way!
