Absence of both circadian rhythm and Trypanosoma cruzi periodicity with xenodiagnosis in chronic chagasic individuals

Absence of both circadian rhythm and Trypanosoma cruzi periodicity with xenodiagnosis in chronic chagasic individuals

Revista Da Sociedade Brasileira de Medicina Tropical 33(5): 427-430

Xenodiagnoses were performed every 3 hours for up to 72 hours consecutively, using 10 Triatoma infestans 3rd instar larvae each time, in 18 chronic chagasic patients with positive serology and/or xenodiagnosis. Of 237 xenodiagnoses performed in total, 87 (36.7%) were positive. There was no statistically significant difference in the positivity of assays performed during the day (9:00 to 18:00) compared to those performed at night (21:00 to 6:00).
