Geographical distribution of Trypanosoma cruzi in triatomine vectors in the Sta...
Cominetti,Marlon Cezar; Csordas,Bárbara Guimarães; Cunha,Rodrigo Casquero; Andreotti,RenatoIntroduction This work presents the initial findings of a molecular epidemiological investigation of Trypanosoma cruzi in triatomine insects in State of Mato Grosso do Sul. Methods A total of 511 triatomines from different regions of the state were examined. Deoxyribonucleic acid (DNA) was extracted from the intestinal contents of the insects using phenol-chloroform-isoamyl alcohol (25:24:1). Polymerase chain r...

Cunha,Rodrigo Casquero; Andreotti,Renato; Cominetti,Marlon Cezar; Silva,Elaine AraújoLeishmaniasis is a zoonotic disease caused by protozoa of the genus Leishmania (Ross, 1903) and is the focus of considerable attention in human and veterinary medicine. In the city of Campo Grande, MS, the causative agent of visceral leishmaniasis is Leishmania infantum (= L. chagasi) primary vector, comprising approximately 92.9% of the local sandfly population, is Lutzomyia longipalpis. The aim of this work w...
Monitoring Trypanosoma cruzi infection in triatomines using PCR in Mato Grosso ...
Cominetti,Marlon Cezar; Almeida,Robson Ferreira Cavalcante de; Goncalves,Guilmara Maria do Amaral; Andreotti,RenatoIntroduction The aim of the present study was to assess the polymerase chain reaction (PCR) as a method for detecting Trypanosoma cruzi infection in triatomines that had been previously determined by microscopic examination in the State of Mato Grosso do Sul, Brazil. Methods In total, 515 specimens were collected. Material from the digestive tract of each triatomine was analyzed for the presence of T. cruzi by ...

Cominetti,Marlon Cezar; Andreotti,Renato; Oshiro,Elisa Teruya; Dorval,Maria Elizabeth Moraes CavalheirosINTRODUCTION: This work was an epidemiological investigation of the risk of Trypanosoma cruzi transmission in the rural Quilombola community of Furnas do Dionízio, State of Mato Grosso do Sul, Brazil. METHODS: Of the 71 animals examined, seven were captured (two opossums, Didelphis albiventris; four rats, Rattus rattus; and one nine-banded armadillo, Dasypus novemcinctus) and 64 were domestic (one canine, Canis...
