Recently, scientists found indirect evidence of colistin-resistant bacteria in the gut of the human body.
About the colistin resistant bacteria
- Presence in poultry and vegetables:The team of scientists found that colistin-resistant Klebsiella bacteria were widely present in poultry and raw vegetables.
- The main cause of colistin resistance in food is due to the rampant use of colistin in poultry.
- Since poultry litter is used as manure to grow vegetables, colistin-resistant bacteria are found in vegetables as well.
- What causes the resistance? In clinical practice, it is the mutation in the mgrB gene or other chromosomal genes that confers colistin resistance to Klebsiella bacteria.
- Scientists noted that colistin resistance due to mutation in food Klebsiella has the potential to spread to human Klebsiella in the gut and hence may contribute to colistin-resistant infections in humans.
- It is found that a huge number of individuals carry colistin-resistant bacteria of food origin in the gut is therefore worrying.
- Colistin is the last-resort antibiotic used to treat highly drug-resistant bacterial infections.
- Colistin-resistant bacteria can be of hospital origin or food origin.
- Colistin-resistant bacteria of hospital origin do not respond to any of the antibiotics, including carbapenem while colistin-resistant bacteria of food origin will respond to carbapenem.
