Importância da distribuição geográfica dos vetores da doença de chagas em Pernambuco, Brasil, em 2012 / The importance of the geographical distribution of Chagas disease vectors in Pernambuco during 2012
Foram examinados 3.323 triatomíneos.A infecção natural por tripanossomatídeos foi detectada em 21,3 por cento dos exemplares. Triatomabrasiliensis foi a espécie mais frequente no intradomicílio (24,3 por cento), Triatoma pseudomaculata(14,9 por cento) e Panstrongylus megistus apresentaram proporcionalmente taxa de infecção naturalsuperior às demais (40,8 por cento) no peridomicílio.
To underscore the importance of geographic distribution and behavior of vectors ofChagas disease in the state of Pernambuco.
Methods:
The material analyzed included 100 percent of theinsects infected with Trypanosoma spp., and 40 percent of negative insects, examined at the EndemicDisease Laboratory for taxonomic confirmation, searching for the parasite in feces of the insects,with Quality Control to confirm the diagnosis.
Results:
A total of 3,323 triatomines. Naturalinfection by trypanosomes was detected in 21.3 percent of the specimens. Triatoma brasiliensis wasthe most frequent intradomiciliary species (24.3 percent), outside the home Triatoma pseudomaculata(14.9 percent) and Panstrongylus megistus had a natural infection rate proportionally superior to the others(40.8 percent).
Conclusion:
The current knowledge of the geographical distribution of Chagas diseasevectors is important as a platform to integrate actions between health services, contributing to theentomological surveillance and control of the insects.
