Abstract

CASTRO, Cleudson  and  PRATA, Aluizio. Absence of both circadian rhythm and Trypanosoma cruzi periodicity with xenodiagnosis in chronic chagasic individuals. Rev. Soc. Bras. Med. Trop. [online]. 2000, vol.33, n.5, pp. 427-430. ISSN 0037-8682.  http://dx.doi.org/10.1590/S0037-86822000000500003.

Xenodiagnoses were performed every 3 hours using 10 Triatoma infestans 3rd instar for 24 to 72 hours, in 18 chronic chagasics with positive serology and/or xenodiagnosis. There was no statistically significant difference in the positivity of assays performed during the day (9:00 to 18:00h) compared to those performed at night (21:00 to 6:00h), (c2 = 0.1526 p = 0.696). Xenodiagnosis was performed in ten of the patients for 13 successive days but there was no periodicity detected in the positive assays.

Keywords : Circadian rhythm; Trypanosoma cruzi parasitemia; Serial xenodiagnoses.
