Trypanosoma cruzi parasitemia observed in immunocompromised patients: the importance of the artificial xenodiagnosis. Rev. Inst. Med. trop. S. Paulo [online]. 2001, vol.43, n.2, pp.113-115.

Trypanosoma cruzi parasitemia observed in immunocompromised patients (transplant or positive HIV) occurred more frequently by the artificial xenodiagnosis method (10/38) compared with hemoculture (2/38), given the same quantity of blood. Other ways of diagnosis, like mice inoculation (5/38), QBC and buffy coat (2/38), were evaluated also. This result showed the importance of the artificial xenodiagnosis. The other techniques increased only one more patient positive.
