Presence of colistin-resistant bacteria of food origin in the gut is cause for worry

A small study has found evidence of colistin-resistant bacteria in the gut. 77% of such bacteria were found to be food-acquired. There is a possibility of colistin resistant food Klebsiella to spread to human Klebsiella in the gut. A small study involving 65 stool samples taken from patients from a single hospital in Chennai found … Continue reading Presence of colistin-resistant bacteria of food origin in the gut is cause for worry

Podcast: How Klebsiella bacteria develop colistin resistance

  Abdul Ghafur explains how the team deciphered the mechanism by which Klebsiella bacteria develop resistance to colistin, a last-line antibiotic. Mutations and insertional inactivation of the mgrB gene, which is present in the chromosome, are responsible for colistin resistance in Klebsiella. The inserational sequence that moves out from the chromosome to plasmid before spreading to other … Continue reading Podcast: How Klebsiella bacteria develop colistin resistance

Mechanism of colistin resistance in food Klebsiella bacteria unravelled

Researchers found colistin-resistant bacteria in 49% vegetable, meat samples in Chennai. They have for the first time deciphered the mechanism by which food Klebsiella bacteria develop resistance to colisitin, a last-line antibiotic. Mutations and insertional inactivation of the mgrB gene, which is present in the chromosome, are responsible for colistin resistance in Klebsiella. A study carried out in … Continue reading Mechanism of colistin resistance in food Klebsiella bacteria unravelled
