Evidence for horizontal gene transfer, gene duplication and genetic variation as driving forces of the diversity of haemolytic phenotypes in Photobacterium damselae subsp. damselae
Abstract
Photobacterium damselae subsp. damselae, a marine bacterium that causes infections in marine animals and in humans, produces up to three different haemolysins involved in virulence, which include the pPHDD1 plasmid‐encoded damselysin (Dly) and HlyApl, and the chromosome‐encoded HlyAch. We screened 45 isolates from different origins, and found a correlation between their haemolytic phenotypes and the differential haemolysin gene content. All highly and medium haemolytic strains harboured pPHDD1, with amino acid substitutions in HlyApl and HlyAch being the cause of the medium haemolytic phenotypes in some pPHDD1...

Recovery of Pseudomonas aeruginosa culturability following copper‐ and chlorine‐induced stress
This study investigated how quickly cells of the opportunistic pathogen Pseudomonas aeruginosa recover culturability after exposure to two of the most common environmental stressors present in drinking water, free chlorine and copper ions. Viable but non‐culturable (VBNC) P. aeruginosa undetected by direct culturing following exposure to free chlorine or copper ions can survive in drinking water systems, with potential to recover, multiply and regain infectivity. Cells were exposed to copper sulphate (0.25 mg Cu2+ L−1) or free chlorine (initial dose of 2 mg Cl2 L−1) for 24h. Despite total loss of culturability and a ...

From the phosphoenolpyruvate phosphotransferase system to selfish metabolism: a story retraced in Pseudomonas putida
Abstract
Although DNA is the ultimate repository of biological information, deployment of its instructions is constrained by the metabolic and physiological status of the cell. To this end, bacteria have evolved intricate devices that connect exogenous signals (e.g. nutrients, physicochemical conditions) with endogenous conditions (metabolic fluxes, biochemical networks) that coordinately influence expression or performance of a large number of cellular functions. The phosphoenolpyruvate:carbohydrate‐phosphotransferase system (PTS) is a bacterial multi‐protein phosphorylation chain which computes extracellular (e.g. su...
