Infecciones por Escherichia coli en cerdos (2 de 2)

Steven McOrist S. McOrist

La colibacilosis postdestete y la enfermedad de los edemas son infecciones comunes en cerdos de todo el mundo – estas cepas de E coli parecen "formar parte" de la mayoría de granjas porcinas por lo que, de momento, la eliminación no es una opción.

Etiología de la enteropatía proliferativa porcina

Steven McOrist S. McOrist

El agente causal de la enteropatía proliferativa porcina (EPP, ileítis porcina) es la bacteria intracelular estricta Lawsonia intracellularis, que crece preferentemente en el citoplasma de las células del epitelio intestinal (McOrist et al., 1995). El crecimiento de esta bacteria se ve acompañado invariablemente de la proliferación localizada de células epiteliales inmaduras de las criptas que están infectadas.
