Abstract excerpt

Microorganisms commonly exist in polymicrobial communities, where they can respond to interspecies secreted molecules by altering behaviors and physiology; however, the underlying mechanisms remain underexplored. Here, we investigated interactions between Stenotrophomonas maltophilia and Pseudomonas aeruginosa, coinfecting opportunistic pathogens found in pneumonia and chronic lung infections, such as in cystic...
