Countering antibiotic resistance using engineered bacteria

Science Rehashed

May 3 2023 • 36 mins

Respiratory infections are a major cause of mortality worldwide and pose unique challenges for healthcare interventions due to the antibiotic-resistant nature of many respiratory pathogens. For patients that require ventilation, an additional complicating factor is a protective substance produced by bacteria known as a biofilm. Biofilms can result in chronic infections, preventing the body and antibiotics from clearing the bacteria away. In this episode, we talk with Dr. Maria Lluch-Senar, a biotechnologist working with engineered Mycoplasma (a type of bacteria) with the aim of leveraging it to treat disease. She shares with us why Mycoplasma is a candidate for these interventions, how her lab modifies the organism, and the process through which these bacteria will help us more effectively treat other bacterial infections. Music featured in this episode includes excerpts from “Elevator Pitch” and “What’s the Angle” by Shane Ivers.
