title: [Studies on the persistence of the infectivity of Trypanosoma cruzi. II. Persistence of infectivity of T. cruzi in dead bugs (author's transl)].
abstract: Investigations into the viability time of T. cruzi in dead bugs experimentally infected with "Peru" strain showed a maximum of 9 days for Dipetalogaster maximus and 8 for Triatoma infestans maintained at ambient temperature (26 degrees C). On refrigeration survival was increased to 60 days. In routine xenodiagnosis in the refrigerator 90 day survival was noted of both T. cruzi and the vector bug.
