(IMAGE) Center for Genomic Regulation Caption This shows a cross-section of a mouse lung infected with Pseudonomas aeruginosa. The mouse was treated with a version of Mycoplasma pneumoniae that is able to produce therapeutic molecules such as pyocins specifically-designed to combat P. aeruginosa. This therapeutic version of M. pneumoniae acts like a ‘living medicine’ reducing the effects of the infection and preserving air in the alveoli.
