Hepatitis B antigen (HBsAg) in wild triatominae in Brazil

A total of 3,200 impressions were fixed on filter paper and were identified as containing human blood obtained from blood-sucking arthropods of the Triatoma and Panstrongylus genre. The impressions were then examined for the presence of the hepatitis B antigen (HBsAg). The immunodifusion technique s...

Sumario:A total of 3,200 impressions were fixed on filter paper and were identified as containing human blood obtained from blood-sucking arthropods of the Triatoma and Panstrongylus genre. The impressions were then examined for the presence of the hepatitis B antigen (HBsAg). The immunodifusion technique showed that 12 impressions were presumably HBsAg positive, but the radioimmunoassay technique only confirmed 7 positive results. The positive samples were all obtained from Triatoma infestans nymphae.
