Molecular diagnosis and typing of Trypanosoma cruzi populations and lineages in cerebral chagas disease in a patient with AIDS
Trypanosoma cruzi DNA was amplified from an intracranial biopsy and peripheral blood of an HIV patient with encephalitis; this episode was indicative of AIDS and congenital Chagas disease. The analysis of a microsatellite locus revealed a multiclonal parasite population at the brain lesion with a mo...
