VTC PS COLI

"VTC COLI-STREP is a water-soluble powder combination of penicillin, streptomycin, Zinc Bacitracin and Colistin.
Penicillin G acts mainly bactericidal against Gram-positive bacteria like Staphylococcus, Streptococcus, Pasteurella, Corynebacterium, Bacillus and Clostridia.
Streptomycin belongs to the group of amino-glycosides. It has a synergetic effect on penicillins, so both products can be combined at lower, less toxic levels.
Zinc Bacitracin is a kind of new antibacterial feed additive holds stable potency. As a complex compound of fermentation product of Bacillus Licheniformin and Zinc Ion, Zinc Bacitracin is mainly used to control germs growth and promote animal’s growth.
Colistin is a cyclic polypeptide antibiotic and has a bactericidal action against selected Gram-negative bacteria. The first bacterial effect of colistin is a blockade of the cell division of bacteria, followed by a secondary progressive lysis. Susceptible bacteria are Aerobacter aerogenes, Escherichia coli, Salmonella spp., Shigella spp., Haemophilus spp., Pasteurella spp., Pseudomonas aeruginosa, Vibrio spp. and paracolon bacteria (MIC values < 5 mcg/ml). Some Pseudomonas species may be primary resistant. Colistin sulphate is hardly absorbed after oral administration (less than 1 % of the administered dose) and therefore remains active only in the gastrointestinal tract."
