Open the CIPO recordAbstract From the Canadian patent
A preparation from the scrapings of healthy animals is cultured and administered to animals. This preparation confers a strong measure of protection against the subsequent colonization by enteropathogenic bacteria including Salmonella species, Campylobacter species and Escherichia coli 0157:H7, which currently cause an unacceptably high incidence of morbidity and mortality in humans and reduce productivity in livestock populations.

Why it's free to use
- Filed October 10, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 10, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 10, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
