Abstract:
Trypanosoma cruzi was isolated from a 20 year old male with no evidence of antibodies against this parasite until 12 months after the isolation and with no electrocardiographic alterations. The isolated sample obtained was characterized as T. cruzi I through PCR mini-exon. It had been reported without serologic reactivity to T. cruzi. It is the first case with lack reactivity reported in Mexico.
