First report on the occurrence of Trypanosoma rangeli Tejera, 1920 in the state of Ceara, Brazil, in naturally infected triatomine Rhodnius nasutus Stal, 1859 (Hemiptera, Reduviidae, Triatominae)


, : First report on the occurrence of Trypanosoma rangeli Tejera, 1920 in the state of Ceara, Brazil, in naturally infected triatomine Rhodnius nasutus Stal, 1859 (Hemiptera, Reduviidae, Triatominae). Memorias do Instituto Oswaldo Cruz 102(5): 643-645

The aim of this work was to identify and report the occurrence of Trypanosoma rangeli and Trypanosoma cruzi in naturally infected Rhodnius nasutus ( Hemiptera, Reduviidae, Triatominae) in the state of Ceara, Brazil. Triatomines feces, salivary glands, and hemolymph were collected for fresh examination, and specific detection of T. rangeli and T. cruzi DNA by polymerase chain reaction was carried out. The specific characterization of these two parasites showed the simultaneous presence of both parasites in two ( 7.7%) of the 26 positive insects. Our results provide further knowledge on the geographical distribution of T. rangeli in Brazil.
