Researchers at the Instituto Oswaldo Cruz (IOC / Fiocruz) are analyzing the cycle of transmission of toxoplasmosis in the Pantanal region. The new study seeks to determine the prevalence of infection by Toxoplasma gandii in wild animals, cattle, sheep, swine and human population.

According to the researchers, the close relationship of wildlife to domestic animals and humans cause expansion of zoonotic infectious agents, such as toxoplasmosis, knowledge of these agents may contribute to the epidemiological understanding and result in prevention and control of disease .

At first, there is the possibility that the wild cat, such as jaguars, ocelots and other cat species are contaminating the pastures with feces containing the parasite. As oxen and sheep, like any other animal, feed this pasture, can be infected. Eating meat from these animals, when prepared and handled improperly, can potentially lead to infection, the researcher explained Magyda Dahroug, adding that consumption of well-cooked meat poses no risk. She predicts that by the year end results must be completed. For expert Regina Amendoeira, the choice of the Pantanal region was essential for the proper development of the research. We chose the Pantanal region because we had never studied this type of biome, said.

About <b> toxoplasmosis </ b>

Toxoplasmosis is an infectious disease acquired congenitally or postnatal, caused by the protozoan Toxoplasma gondii, whose form of resistance (the cyst) is found in the feces of cats and other felines. Men and other animals can also stay in the form of cysts in their tissues. The disease can be acquired by ingestion of contaminated food and may present clinical cases ranging from asymptomatic to those with severe manifestations in the myocardium, liver and central nervous system. It can also cause fever, fatigue, headache, lymph infarcted and body aches.
