Amplification and analysis of human DNA present in mosquito bloodmeals

Abstract
DNA fingerprinting should permit the identification of individual human hosts of hematophagous arthropods, providing epidemiologically useful information, for example, the biting rates on different people and the impact of insecticide-impregnated bednets. Investigations reported here demonstrate that it is possible to extract, amplify and fingerprint human DNA from the bloodmeals of individuals female Anopheles gambiae mosquitoes kept at 24.degree. C for up to 10-15 h post-ingestion.
