SrbA sRNA

SrbA (sRNA regulator of biofilms A) is a small regulatory non-coding RNA identified in pathogenic Pseudomonas aeruginosa . It is important for biofilm formation and pathogenicity. Bacterial strain with deleted SrbA had reduced biofilm mass. As the ability to form biofilms can contribute to the ability a pathogen to thrive  within  the host, the C. elegans  hosts infected with the srbA deleted strain displayed significantly lower mortality rate than the wild-type strain. However, the deletion of srbA had no effect on growth or antibiotic resistance in P. aeruginosa.
