Aliseryl WS is a highly effective combination of broad-spectrum antibiotics and vitamins.
Colistin is an antibiotic from the group of polymyxins with a bactericidal action against Gram-negative bacteria, like E. coli, Haemophilus and Salmonella. Since colistin is absorbed for a very small part after oral administration only gastrointestinal indications are relevant. Oxytetracycline belongs to the group of tetracyclines and acts bacteriostatic against many Gram-positive and Gram-negative bacteria, like Bordetella, Campylobacter, Chlamydia, E. coli, Haemophilus, Mycoplasma, Pasteurella, Rickettsia, Salmonella, Staphylococcus and Streptococcus spp. The action of oxytetracycline is based on inhibition of bacterial protein synthesis. Oxytetracycline is mainly excreted in urine, for a small part in bile and in lactating animals in milk. Erythromycin is a macrolide that acts bacteriostatic against mainly Gram-positive bacteria, like Staphylococcus and Streptococcus spp. Streptomycin is an aminoglycoside with a bactericidal action against mainly Gram-negative bacteria, like E. coli, Klebsiella, Pasteurella and Salmonella spp. and Mycoplasma. Vitamins are essential for the proper operation of several physiological functions.
