Each ml contains:

Colistin (sulphate)



Target species: Calves, kids, lambs and Poultry


Baycolisty® is indicated for gastrointestinal infections caused by colistin sensitive microorganisms like E. coli, Haemophilus and Salmonella spp.

Mechanism of action:

Colistin sulphate is an antibiotic from the group of polymyxins with bactericidal activity against gram-negative bacteria like E. coli, Haemophilus and Salmonella spp. Polymyxins interact strongly with phospholipids, penetrate into, and disrupt the structure of cell membranes. They disorganise the outer membrane of gram-negative bacteria by binding lipopolysaccharide (LPS) and thereby neutralising the endotoxin capacity of LPS. Orally administered colistin is eliminated in faeces.
