Parasitemia constante durante 24 horas consecutivas na infecção experimental pelo Trypanosoma cruzi

By Ítalo A. Sherlock

Abstract

Observou-se aparasitemia horária do Trypanosoma cruzi através de hemoscopias e de xenodiagnósticos horários, em camundongos na fase aguda da infecção e em cobaias e camundongos na fase crônica. O número de T. cruzi no sangue e o número de triatomíneos positivos por xenodiagnósticos foi freqüente e variável mas não foi cíclico durante as 24 horas do dia. A qualquer hora, tanto na fase aguda como na crônica, o T. cruzi pôde ser detectado através hemoscopias e xenos. Não foi constatado um ritmo circadiano para o T. cruzi.<br>The hourly parasitaemia of Trypanosoma cruzi in mice with acute infection and in mice and guinea pigs with chronic infections was checked by means of hourly blood examinations and xenodiagnosis. The number of T. cruzi in the blood and the number of positive xenodiagnosis in both acute and chronic infections was frequent and variable but not cyclical during the 24 hours of the day. T. cruzi was demonstrable at any time of the day by either blood examination or xenodiagnosis
