Infezioni da Escherichia coli

La colibacillosi post-svezzamento e la malattia degli edemi sono infezioni comuni nei suini di tutto il mondo – questi ceppi di E coli sembrano "far parte" della maggior parte degli allevamenti di suini; pertanto, la possibilità di eradicazione per il momento non è un'alternativa. La vaccinazione delle scrofe o scrofette con vaccini nei confronti del coli ETEC, non produce alcun effetto sulle infezioni da E. coli post-svezzamento.
