THE Chagas diseasecaused by a parasite and transmitted mainly by the “barber” insect, had a new species identified by researchers from the Oswaldo Cruz Institute (IOC/Fiocruz). The discovery, which had the help of scientists from Uruguay and Bolivia, was published in the journal “Zoo Keys», a scientific platform.

The new species was named “Panstrongylus noireaui», a tribute to the French researcher François Noireau. According to the institution, the species belongs to a genus of great medical importance for participating in the transmission of the protozoan. Trypanosoma cruzimain cause of the disease.

The identification came from a study that found genetic and molecular differences in specimens that until then had been described as belonging to the species. Panstrongylus rufotuberculatus, already known to the scientific community. Both belong to the family of insects commonly known as barbers. However, although the two species are very similar, a genetic analysis was carried out in which it was possible to observe a small distinction between them.

It should be noted that the Chagas disease It is transmitted through the barber’s feces. In the acute phase, it causes symptoms such as fever for more than seven days, headache, and swelling of the face and legs. In the chronic phase, it can cause heart and digestive problems.
