Colistin Sulfate Powder 99% CAS 1264-72-8 for Animal Use

Colistin Sulfate (CS) plays a significant role in veterinary medicine, particularly in the treatment of animals. Here are some key points regarding its use and effects in animals:

1. Treatment of Enteric Infections: Colistin sulfate is extensively used in animals, especially in pigs, for the control of enteric infections caused by Gram-negative organisms such as Enterobacterales, Acinetobacter baumannii, and Pseudomonas aeruginosa .

2. Growth Promotion: In certain countries, colistin has been used as a growth promoter in swine production, although this practice has been banned in some regions due to concerns about antibiotic resistance .

3. Therapeutic Use: Colistin is administered orally, topically, or via injection to treat a variety of terrestrial and aquatic animal species . It is particularly used to treat digestive disorders but also as a growth promoter in certain countries .

4. Resistance Concerns: The use of colistin in animals has raised concerns about the emergence of antibiotic resistance, especially with the discovery of the plasmid-borne mcr gene, which confers resistance to colistin .

5. Pharmacokinetics and Dosage: Studies have been conducted to understand the pharmacokinetics of colistin in animals, optimizing dosage for effective treatment while minimizing the risk of resistance development .

6. Impact on Gut Microbiome: Colistin treatment has been shown to increase piglet gut microbiome diversity and can significantly alter the composition of the gut microbiome, affecting both beneficial and harmful bacteria .

7. One Health Approach: The use of colistin in animals is closely monitored due to its importance in human medicine and the potential for resistance to spread between animals and humans, emphasizing the need for a One Health approach to manage antibiotic resistance
