EXPERIMENTAL INFECTION MODEL TO OBTAIN E. GRANULOSUS ADULT FORMS AND SECONDARY HYDATIDIC CYSTIC IN THE GOLDEN HAMSTER (MESOCRICETUS AURATUS)

EXPERIMENTAL INFECTION MODEL TO OBTAIN E. GRANULOSUS ADULT FORMS AND SECONDARY HYDATIDIC CYSTIC IN THE GOLDEN HAMSTER (MESOCRICETUS AURATUS)

The objective of the study was to evaluate an alternative animal model to the use of canines as definitive host and the use of sheep as definitive host of Echinococcus granulosus. Thirty three female Golden hamsters (Mesocricetus auratus) were used. In group A, 16 animals of one month of age were orally infected with 3000 viable protoscoleces of E. granulosus; and in group B, 17 animals of 4.5 months of age were intraperitoneal infected with 1500 viable protoscoleces. All protoscoleces were obtained from fertile cysts collected from naturally infected sheep. No adult forms of E. granulosus were recovered from group A, while in group B secondary hydatid cysts were recovered in 9 animals (52.9%) at 2.5, 3.5 and 6.5 months after infection. All recovered cysts were infertile.

El objetivo del estudio fue evaluar un modelo animal alternativo al uso de caninos como hospedero definitivo y al uso de ovinos como hospedero definitivo de Echinococcus granulosus. Se utilizaron 33 hámster dorados (Mesocricetus auratus) hembras. El grupo A, conformado por 16 hámster de un mes de edad fue infectado, vía oral, con 3000 protoescólices viables de E. granulosus por animal; y el grupo B, conformado por 17 hámster de 4.5 meses de edad fue infectado, vía intraperitoneal, con 1500 protoescólices viables por animal. Todos los protoescólices provenían de quistes fértiles de ovinos naturalmente infectados. No se logró obtener E. granulosus adultos en los animales del grupo A, mientras que en el grupo B se obtuvo quistes hidatídicos secundarios en 9 animales (52.9%) a los 2.5, 3.5 y 6.5 meses post-infección; sin embargo, todos los quistes obtenidos fueron infértiles.
