Phenotypic characteristics contributing to the enhanced growth of Escherichia coli bloom strains

Nanayakkara, Buddhie; O'Brien, Claire; Gordon, David


During bloom events,Escherichia colicell countsincrease to between 10,000 and 100,000 cfu/100 mlof water. The strains responsible for bloom eventsbelong toE. coliphylogenetic groups A and B1,and all have acquired a capsule fromKlebsiella.Apan-genome comparison of phylogroup AE. colirevealed that the ferric citrate uptake system(fecIRABCDE) was overrepresented in phylogroupA bloom strains compared with non-bloomE. coli.A series of experiments were carried out to investi-gate if the capsule...[Show more]
