Maltose aids in the growth of Salmonella Typhimurium in nitrogen-deficient conditions

Kirti Parmar, Yachna Kumari, Muralidhar Nayak M, Kapudeep Karmakar, Sumanta Bagchi, Dipshikha Chakravortty

This study shows maltose enhances Salmonella Typhimurium growth under nitrogen-deficient conditions but impairs its pathogenicity.

The resilience of Salmonella to bile stress is impaired due to the reduced efflux pump activity mediated by the antioxidant enzyme YqhD

Kirti S. Parmar, Yachna Kumari, Raju S Rajmani, Dipshikha Chakravortty

This study shows that YqhD in Salmonella reduces reactive oxygen species and efflux pump activity, impairing bile resistance, and that its mutation increases survival in bile stress conditions.
