What is MCR disease?
What is MCR disease?
In November 2015, mcr -1—a gene that can make bacteria resistant to colistin, an old antibiotic that is the last-resort drug for some multidrug-resistant infections—was reported in China. The mcr -1 gene is on a plasmid, a small piece of DNA that is able to move from one bacterium to another.
What is MCR positive?
mcr positive Enterobacteriaceae are bacteria of the family Enterobacteriaceae confirmed to have one of the family of mcr genes. Confirmation of the presence of the mcr gene should be by a reliable method, such as a molecular method. Epidemiological criteria. Not relevant for surveillance purposes.
What is the MCR treatment?
The mobilized colistin resistance (mcr) gene confers plasmid-mediated resistance to colistin, one of a number of last-resort antibiotics for treating Gram-negative infections. mcr-1, the original variant, is capable of horizontal transfer between different strains of a bacterial species.
What bacteria is colistin used to treat?
Colistin, also known as polymyxin E, is an antibiotic medication used as a last-resort treatment for multidrug-resistant Gram-negative infections including pneumonia. These may involve bacteria such as Pseudomonas aeruginosa, Klebsiella pneumoniae, or Acinetobacter.
What are MCR genes?

What is the origin of the MCR-1 gene?
A new study by a team of British and Chinese researchers suggests that the colistin-resistance gene MCR-1 began to emerge almost a decade before it was first identified, and likely originated in Chinese livestock.
What are last-resort antibiotics?
A last-resort antibiotic is used to treat infections with bacteria that are resistant against the common antibiotics or, in cases of severe infections, where an effect must be ensured. Synonyms. Reserve antibiotic.
Is colistin banned in India?
India: Central Government Bans Use of Colistin In Livestock To Tackle Anti-Microbial Resistance. On July 19, 2019, the Central Government banned the manufacture, sale and distribution of Colistin and its formulations for food producing animals, poultry, aqua farming and animal feed supplements with immediate effect1 .
Is colistin a growth promoter?
For instance, colistin is widely used as a growth promoter in the production of food animals in India specifically in poultry sector58. Colistin sulphate, an antibiotic used as a growth promoter, is easily available in the market without the need for prescription.
Is colistin a bactericidal?
Tigecycline and colistin act on bacterial cells by different mechanisms: tigecycline by inhibition of protein synthesis and colistin on the outer cell membrane. Also, tigecycline is bacteriostatic by nature, whereas colistin is bactericidal. Therefore, there is a potential scope for both antagonism and synergy.
