La crianza del sajino (Tayassu tajacu) en cautiverio en nuestra amazonía está orientada a la obtención de carne y cuero, este último con fines de exportación para la fabricación de guantes y peleterías, manteniéndose el Perú como único exportador mundial de cueros de esta especie. Sin embargo, en la producción de esta y otras especies silvestres tropicales presentan escasos estudios que determinan las enfermedades infecciosas y/o parasitarias que ocasionan bajas en su producción. Tal es el caso del Trypanosoma sp. donde algunas de sus especies son zoonóticos. El objetivo del presente estudio fue determinar la presencia de Trypanosoma sp. en sajinos en cautiverio de Iquitos y Moyabamba. Se colectaron muestras de sangre de 38 sajinos procedentes de tres zoocriaderos y cuyas edades fluctuaban entre 3 meses y 2 años. Las técnicas diagnósticas empleadas fueron del microcapilar o técnica de Woo y del Frotis sanguíneo delgado. No se halló la presencia de Trypanosoma sp. en las muestras examinadas por diferentes razones entre ellas la baja sensibilidad de las técnicas usadas. La técnica de evaluación de riesgo por simulación Monte Carlo (programa @Risk) indico que el 95% de las observaciones analizadas se encontraron en un intervalo de 0.006 a 0.854% y que la probabilidad de encontrar la infección real en sajinos provenientes de Iquitos y Moyobamba se encuentra en un rango promedio de infección de 0.02%. Por ello se recomienda el uso de técnicas de mayor sensibilidad como el PCR. / In our Amazon region, the upbringing of the collared peccaries (Tayassu tajacu) in captivity is faced to the securing of meat and leather, the last one with ends of exportation for the manufacture of gloves and furrier's, being supported Peru as exporting world only one of leather of this species. Nevertheless, in the production of this one and other wild species of the Amazon region few ones are the studies destined to determine the infectious and/or parasitic illnesses that they cause low in his production. Such is the case of the Trypanosoma sp. which has been brought in a fortuitous way in collared peccaries, not going so far as to determine the implied species, fact that receives big importance because someone species of this parasite are zoonotics. The objective of the present study was to determine the presence of Trypanosoma sp. in collared peccaries in captivity of Iquitos and Moyobamba, for which they were sampled 38 collared peccaries proceeding from three breeding grounds and whose ages were fluctuating between 3 months and 2 years. The used tests were of the microcapillary or method of Woo and of the blood smear. The realized analyses did not allow us to determine the presence of the Trypanosoma sp. in the analyzed samples, nevertheless these results it does not indicate us that the illness should not exist in the collared peccaries of our Amazon region, but rather he allows us to conclude that they are more exhaustive necessary studies, with the employment of test with major sensibility as that of the PCR, which allow us to determine the real presentation of this illness, as well as to determine if it is that the Trypanosoma sp. in the collared peccaries, he behaves like in pigs in whom his detection is difficult for routine methods, since the period of parasitaemia is short.
