So Paulo, 09 – Researchers at the University of Texas were able to map the movements of the barber, who transmits Chagas' disease, using a radio microtransmitter coupled with the 39; insect. The study followed the behavior of the animal for three years and the first to use this technique to monitor insect vectors of diseases. The data was published Monday in the Journal of Medical Entomology
discovered by the Brazilian doctor Carlos Chagas, Chagas disease caused by the parasite Trypanosoma cruzi and transmitted mainly by the barber. It can also pbad from me to a child, through blood transfusions, or through a transplanted organ from an infected donor.
The initial symptoms are similar to those of the flu, but if left untreated, the disease becomes chronic and causes cardiac and digestive changes. The disease has an impact on Latin America and the southern United States.
A difficulty in studying these insects is the fact that they tend to move during the night and to hide all day long. For this new pilot study, the team relied on the help of three residents who reported the frequent appearance of the barber at home and, after catching insects, the researchers detained radio transmitters of only 0.2 grams on the back of animals using supercollate
The micro equipment was painted with a fluorescent paint to facilitate the process of recapture of the 11 barbers observed in the study.
18 movements were followed in periods ranging from one to 12 days, and the researchers reported that,
beetles and bees were already being monitored by radio transmitters in the course of studies, but no such badysis had ever been done with arthropod vectors.
This method is suitable for the study of barbers who, according to the study participants, have a low population density, so a large scale. and achieve results.
According to the main author of the study, Assistant Professor of Entomology Gabriel Hamer, badysis of the movement of the barber can help in actions to avoid the exposure of animals and humans to the vector of the disease
