e and, in turn, reduce the risk to human health. Most strains of E. coli are harmless but some, like O157:H7, can cause severe illness and even be fatal when ingested by humans from contaminated meat, vegetables or water. Vaccination of cattle with Econiche can help reduce the risk of food and waterborne contamination with E. coli O157:H7.
"Cows carry E. coli O157:H7 but they don't get sick. Where the disease manifests itself is people encountering contaminated food or water, usually from cow feces," said Dr. Brett Finlay, University of British Columbia microbiologist and bacterial diseases expert, whose research led to the development of the vaccine. "If we block the colonization of cows by O157, we basically decrease the number that humans are exposed to, and thus, dropping the disease levels in humans."
On-farm interventions to reduce the shedding of E. coli O157:H7 by cattle, such as simple vaccination of cattle with Econiche, have the potential to reduce food and water contamination and the consequences associated with human infection with the deadly bacteria. Clinical trials conducted with Econiche have shown a significant reduction in the amount of E. coli shed in the manure of vaccinated cows.
Human exposure and infection with E. coli O157:H7 can result in serious health consequences, including abdominal pain and severe bloody diarrhea. In severe cases, kidney damage can occur and progress to serious complications and even death.
Econiche is manufactured in the Bioniche production facility in Belleville, Ontario, where a $25-million expansion is taking place, supported by the Ontario and Canadian governments. Vaccine supply will be limited during this manufacturing expansion period.
About E. coli O157:H7
An estimated 100,000 cases of human infection with the E. coli O157:H7 organism are reported each year in North America. Two to seven per cent of those people develop haemolytic ure
