Summary: | After vaccination with the live PF strain of Trypanosoma cruzi, 194 blood cultures were performed in 143 mice, 9 dogs, 5 Cebus monkeys and 7 human subjects. Some of these blood cultures were simultaneously done with xenodiagnosis, subinoculation in baby mice and/or culture of viscerae. The trypanosomes isolated from the few positive cases (6,1%) were incapable of infecting baby mice were considered as cases of immunotolerance. All the other tests were negative. |
