ABSTRACT
OBJECTIVE:
To verify the incidence of T. cruzi transmission through breastfeeding during acute experimental Chagas' disease.METHODS:
Fifteen female Swiss mice were mated and, after pregnancy confirmation, placed in individual cages. A few hours after birth, the females were inoculated with 0.1 mL of blood containing approximately 3 x 10(5) trypomastigote forms of Y strain of T. cruzi and continued breastfeeding for 25 days.RESULTS:
In 142 offspring examined no infection through breast-feeding was observed.CONCLUSIONS:
The low number of trypomastigote forms ingested by the newborn mice combined with biological and biochemical characteristics of blood trypomastigotes may explain the lack of transmission in this experiment.
