New in JB: Déraspe, Roy et al. perform a comparative genomics study of the PA7-clade of P. aeruginosa - now recognized as a distinct species, Pseudomonas paraeruginosa. This analysis revealed 2 sub-clades, the lack of T3SS & multiresistance.

Pseudomonas aeruginosa senses exopolysaccharide trails using type IV pili and adhesins during biofilm formation - Nature Microbiology
Opposing forces generated by exopolysaccharide trail binding versus type IV pilus retraction generate a high cyclic diGMP–high cyclic AMP state in Pseudomonas aeruginosa that promotes social motility.
