Detection and significance of inapparent infection in chagas disease in western Venezuela
Añez Reverol, Nestor Oswaldo; Rojas E., Agustina del V.; Crisante R., Gladys E.; Carrasco Guerra, Hugo A.; Parada F., Henry; Yépez, José Yancarlos; Borges P., Rafael E.; Guevara, Palmira; Ramirez, José Luis (Am. J. Trop. Med. Hyg., 65(3), 2001, 2001)Inapparent infections of Trypanosoma cruzi were detected in symptomless seropositive people living in close proximity, and under the same conditions of risk, to patients with acute Chagas disease. Similar infections were ... -
Detection of Leishmania causing visceral Leishmaniasis in the old and new worlds by a polymerase chain reaction assay based on telomeric sequences
Chiurillo, Miguel Angel; Sachdeva, Monica; Dole, Vananda S.; Yépez, José Yancarlos; Miliani, Efraim; Vázquez, Laura; Rojas E., Agustina del V.; Crisante R., Gladys E.; Guevara, Palmira; Añez Reverol, Nestor Oswaldo; Madhubala, Rentala; Ramirez, José Luis (Am. J. Trop. Med. Hyg., 65(5), 2001, 2001)We present a new polymerase chain reaction assay based on telomeric sequences of Leishmania donovani. When this assay was used in dilutions of purified L. donovani DNA, a strong amplification signal was observed with 1 fg ... -
