Summary: | Objective. To detect the presence of specific antibodies against Hepatitis E virus (HEV) in pigs slaughtered in Antioquia, the department where the greatest amount of pork is produced and consumed in Colombia. Materials and methods. Between September 2011 and May 2012, blood samples from pigs were obtained in five slaughterhouses of Antioquia, four of them located in the Aburra Valley subregion and other located in northern subregion. Serum were evaluated with a commercial ELISA kit for diagnosing HEV in humans but adapted to detect IgG and IgM antibodies in pigs. Results. A 100.0% seropositivity for IgG antibodies was found in 1000 samples evaluated, and 82.06% for IgM antibodies were found in 740 samples. Conclusions. These results indicate that pigs in slaughter age in Antioquia, and possibly in Colombia, have been exposed to HEV at some point in their production process and a high percentage of them can arrive to slaughterhouses with recent infection. Key Words: Antibodies, ELISA, Hepevirus, IgM, IgG, zoonosis (Source: DeCS). Objetivo. Detectar la presencia de anticuerpos especificos contra el virus de la Hepatitis E (HEV) en cerdos faenados en Antioquia, departamento donde se produce y consume la mayor cantidad de carne de cerdo en Colombia. Materiales y metodos. Entre septiembre de 2011 y mayo de 2012, se obtuvieron muestras de sangre de cerdos en cinco plantas de faenado, cuatro de ellas ubicadas en el Valle de Aburra y una en la subregion Norte del departamento de Antioquia, las cuales fueron evaluadas mediante un kit de ELISA comercial para diagnostico de HEV en humanos pero adaptado para la deteccion de anticuerpos tipo IgG e IgM en cerdos. Resultados. Se encontro una seropositividad de 100.0% para anticuerpos tipo IgG en 1000 muestras evaluadas y de 82.06% para anticuerpos tipo IgM en 740 muestras. Una muestra de heces positiva para la deteccion del genoma HEV es similar al genotipo 3 encontrada en Estados Unidos. Conclusiones. Estos resultados indican que los cerdos en edad de faenado en Antioquia y posiblemente en Colombia, han tenido exposicion a HEV del, un virus zoonotico emergente a nivel mundial, en algun momento de su proceso productivo. Palabras clave: Anticuerpos, ELISA, Hepevirus, IgM, IgG, zoonosis (Fuente: DeCS). |
