 es Respuesta humoral de IgM e IgG en cerdos Criollos Mexicanos y Comercial, predestete sin reto inmunológico inducido
Mejía-Martínez, Karina; Lemus-Flores, Clemente; Zambrano-Zaragoza, José Francisco & González-Morteo, Carlos A.

Resumen

En el presente estudio se analizó la respuesta humoral IgM e IgG en Cerdos Criollos Mexicanos (Cerdo Cuino y Cerdo Pelón Mexicano), comparados con cerdos comerciales (CCO), F1Yorkshire-Landrace, para establecer diferencias que pudieran ser utilizadas como indicadores de resistencias a enfermedades. La muestra fue de 76 cerdos destetados a los 45 días de edad sin vacunación, se tomaron muestras de sangre al destete para evaluar niveles de anticuerpos IgM e IgG por ELISA, contra la vacuna Bacterina Mixta Porcina, que contiene cepas de Salmonella check for this species in other resources , Escherichia coli check for this species in other resources y Pasteurella check for this species in other resources , utilizando la misma mezcla antigénica sonicada para sensibilizar las placas. Los niveles de IgM anti-Bacterina Mixta Porcina fueron más altos en el Cerdo Pelón Mexicano (CPM) que en las otras razas (P <0,0001). Los niveles de anticuerpos IgG anti-Bacterina Mixta Porcina entre el Cerdo Cuino (CC) y el CPM, fueron iguales, sin embargo, ambas razas criollas fueron diferentes que los CCO, (P <0,0001), que tuvieron menor respuesta. Los resultados indican que los CPM, y en menor medida los CC, tienen una mejor respuesta humoral contra Salmonella, Escherichia coli y Pasteurella que los CCO sin reto inmunológico inducido.

 en Humoral immune response of IgM and IgG in Mexican Creole pig and commercial preweaning without induced immunological challenge

Abstract

In the present study the IgM and IgG humoral response was analyzed and compared between Mexican Creole Pigs (Cuino pig and mexican hairless pig) and commercial pigs (CP) F1 Yorkshire-Landrace, to establish differences that allowed to use them like indicator of resistance to disease. Seventy six weanling pigs to the 45 days of age without vaccination were included. A blood sample was obtained at weaning to evaluate the IgM and IgG antibody level to the bovine Pig Mixed Bacterin, contains stocks of Salmonella check for this species in other resources , Escherichia coli check for this species in other resources and Pasteurella check for this species in other resources , by ELISA. The sonicated Bacterin was used to sensitize plates. The IgM anti-bacterin levels were higher in mexican haerless pig (MHP) that in the other breeds (P <0,0001). No differences in the IgG anti bacterin levels between Cuino Pigs (CC) and MHP were found, nevertheless both Creole breeds were different that the CP (P <0,0001), who showed a lower antibody response. Our results show that MHP and CC have both a better humoral response to Salmonella, Escherichia coli and Pasteurella than CP.
