With veterinarians are frequently consulted regarding this disease. And since, by the particular characteristics of the life cycle of the causative agent, many doctors and other health professionals are still confused about how human infection and the proper role of pet cats in the transmission of the disease, rarely noted that the general population is poorly informed about the problem, which, in certain circumstances, generate unnecessary conflicts and anxieties. This note seeks to clarify the main aspects of this pathology, the responsibility of the pet cat, and the precautions to be taken with respect to it.
Description: Toxoplasmosis is a parasitic disease caused by a microscopic parasite (not visible to the naked eye) called Toxoplasma gondii, which can affect any warm-blooded animal subject, including humans and birds. We know that worldwide there are over 500 million people affected. Asymptomatic chronic form affects more than 50% of the human population of the United States Norteamérica.Este small body goes through different and reproductive stages of development, but particularly one of its forms makes it resistant and allows perpetuation in nature. This form is called oocysts, and we know that they can only occur in members of the cat family. That is the fundamental importance of the cat: The oocysts produce those resistant to the disease can persist in nature and can be transmitted. But beyond this, the cat does not play a major role in the development of human disease or animal.Ya once within a body, the parasite multiplies and invades the organs by producing signs of acute infection, and then you can encysting in tissues. Sometimes, only the cyst without producing any disease, which provides the bearer of antibodies that will eventually protect you from further reinfection. How
infects humans: People become infected by congenital transmission (through the placenta), or through ingestion of raw infected meat or undercooked meat or by contact with it, or by ingestion of oocysts. The most common source of infection appears to be the consumption of undercooked meat, especially pork and sheep. Apparently, few infections from beef. Rabbit meat is also important in this regard. The poor hygiene of food and utensils used in cooking is also important. It should be note that the tap water, by itself, effectively kills the parasite in certain forms such superficies.Con about cats, there is evidence that having a cat as a pet, have direct contact with cats, or work with them ( for example, a veterinarian), there is a major risk factor for the person involved. What
the infection in cats: Most cats become infected with Toxoplasma do between 6 months and one year of age, they begin to hunt, and maybe eat a mouse or a bird infected . After this primary infection, the cat begins to eliminate oocysts (parasite-resistant form) process that takes between 10 and 15 days. Then come the antibodies and the cat does not remove more oocysts in his life. The only way you can remove it again if you have a demolition of their defenses by a terrible disease immunosuppressive. But this is very rare. Since then, it is very little time in which a cat eliminates oocysts in their stool, the risk of human infection from cats is very low. It should also be noted that for infectious, oocysts expelled by the cat, must mature (sporulate). And that process they claim 2 or 3 days. That is dangerous not just come out with the feces of cats. Therefore, if care is taken to eliminate the cat litter daily, the risk is almost nonexistent. How
infect other animals herbivores (who we eat their meat) are infected by eating, along with grass, mature oocysts spread by a cat. We get infected if they eat undercooked meat from these infected animals.
congenital infection in humans: The embryo can be infected through the placenta only if your mother has a primary infection (ie if making first contact with the parasite) during pregnancy. In these cases the baby may suffer damage of varying severity, including nerve damage, eye, and even death. If women had antibodies before become pregnant, the baby will have no problem although her mother may have contact with Toxoplasma.
Laboratory tests: The most common test for the detection of antibodies in humans, is the Sabin-Feldman dye.
prophylaxis and precautions: There are several measures that will allow us to minimize the risk of infection: 1 - Cook meat thoroughly and carefully clean the utensils used in cooking. 2 - Wash the vegetables, especially those eaten raw. 3 - As the cats become infected by eating contaminated rodents and birds, try as far as possible, to control the hunting habits. 4 - Eliminate daily feces cats. That will ensure that if the cat is infected and then being eliminated oocysts, they will not mature and become dangerous at home. To the extent possible pregnant women should avoid handling cat feces that have recently come to the house.
Final Thoughts: I hope this note has clarified quite the controversial topic of toxoplasmosis. And that distressed pregnant women having a cat for several years and receive an indication (sometimes the individual physician) to get rid of him, know that this cat (and almost certainly any other) will get sick. And therefore can still enjoy it without risks purrs of her beloved pet. Or at least less risk than it involves eating a steak and salad.
