Biologists and laboratory technicians at the Central Laboratory of Public Health (Lacen), a unit run by the Parreiras Horta Health Foundation (FSPH), participated in training to identify snails of the Biomphalaria species, the parasitic vector that transmits schistosomiasis. This activity was promoted by the Department of Morphology of the Federal University of Sergipe (UFS) and dealt with the morphological characteristics of freshwater snails in the state.

According to biologist Marta Leão, who works in the Laboratory of Entomology, Parasitology and Zoonoses in Lacen, the training provides more knowledge for the research and differentiation of snails. She also informed that in Sergipe, two genera of snails, Biomphalaria glabrata and Biomphalaria stramínea, were found. “Schistosomiasis infection occurs when people come into contact with fresh water where these types of infected snails are present,” the biologist explained.

According to the Director of Entomology and Parasitology, Karen Mora, the health promotion activity proposes the improvement and modernization of technologies, aimed at professionals working in the diagnosis of schistosomiasis. “This is a disease that is endemic in our state and is transmitted by snail. Correct diagnosis is essential to assist in treatment with a view to providing quality services to the population of Sergipe,” the director stressed.

According to data from the Lacen Parasitology Laboratory, an average of 4,000 tests are performed annually to monitor the quality of the schistosomiasis control program. In 2021, the sector recorded 3,854 analyzes, and in 2022, it recorded 4,235.

Parasitology

Schistosomiasis is a disease caused by Schistosoma mansoni, a parasite whose definitive host is human and that needs a freshwater snail as an intermediate host to develop its evolutionary cycle. The disease can be diagnosed through laboratory tests of stool or even an antibody test to check for signs of infection.
