Resumen del taller sobre el uso de la reacción en cadena de la polimerasa (PCR) para distinguir entre Trypanosoma cruzi y tripanosoma rangeli

Abstract: Este taller se realizó con el propósito de transferir la tecnología de la reacción en cadena de la polimerasa (PCR) para la detección de J. cruzi y J . rangeli a laboratorios en Colombia involucrados en el diagnóstico y estudios epidemioló-gicos de la enfermedad de Chagas. Para demostración de la técnica se utilizaron muestras clínicas y epidemiológicas de áreas endémicas colombianas.En los ensayos se emplearon muestras de tripanosomas provenientes de diferentes medios de cultivo para evaluar el posible efecto… Show more

“…It was isolated from a primate, Aotus trivirgatus, in 1982 in San Marcos, Sucre, Colombia, and was identi®ed by polymerase chain reaction (PCR; Campbell et al 1993). Moreover, an experimental study on Rhodnius prolixus was done in our laboratory to corroborate the parasite's transmission via the bug's, saliva.…”

“…These strains were provided by Laboratorio de Parasitología, Instituto Nacional de Salud, (INS) (Bogotá, Colombia). Both parasites species were characterized by isoenzymes 24 and PCR using miniexon and minicircle sequences as targets 5,31,33 . The bulk parasite mass was cultivated in REI modified liquid medium, supplemented with 2% FCS and 100 µg/mL of gentamicin, and incubated at 24 °C.…”

“…Due to direct microscopic detection of trypanosomes, the traditional method for assessment of infection in vectors is not able to distinguish T. cruzi from T. rangeli infection, several polymerase chain reaction techniques have been developed 3,4,5,6,9,13,19,28,33,36,40,41 . However, current PCR assays used for mixed infection detection show some disadvantages such as the amplification of bands of similar size both in T. cruzi and T. rangeli 27,28 , the amplification of polymorphic fragments 11,19 , and bias to T. cruzi in the case of mixed T. cruzi and T. rangeli infection 9,33,36 .…”
