Coliscour is a colistin-based antimicrobial, which is a drinking water-based medication.

CEVA says the product has zero levels of resistance, is easily and efficiently administered in drinking water via header tanks or dosing pumps and it is approved to treat severe bacterial infections, particularly those due to E.coli and Salmonella spp.

Phil McGuire, CEVA’s business unit manager, said: "We simply felt that the easiest way to avoid confusion between our product and a totally different non-prescription product of a similar name was to give ours a new name that also reflects its use, hence Coliscour."
