        Product Description

     Gentamicin Sulfate, a water-soluble antibiotic of the aminoglycoside group, is derived by the growth of Micromonospora purpurea, an actinomycete.

    Gentamicin is an aminoglycoside antibiotic composed of a mixture of related gentamicin components and fractions and is used to treat many types of bacterial infections,

    particularly those caused by Gram-negative organisms.

    Gentamicin is also ototoxic and nephrotoxic, with this toxicity remaining a major problem in clinical use.

    Function&Application

     

    1. Colistin sulphate is the basic peptide antibiotics, mainly for the prevention and treatment of susceptible infections and promote animal growth.  
    2. Colistin sulphate can be combined with the cell membrane lipoprotein phosphate free, making the cell membrane surface tension decreases, increased permeability, resulting in the cytoplasm outflow of cell death.  
    3. Colistin sulphate has a strong inhibitory effect against gram-negative bacteria (particularly E. coli, Salmonella, Pseudomonas aeruginosa, Proteus and Haemophilus, etc.),has no effect on Gram-positive bacteria (Staphylococcus aureus and except hemolytic streptococcus outside) and fungi.  
    4. Colistin sulfate oral is difficult to absorb, less toxic, easy to cause drug residues, easy to produce drug resistance.
