Environmental microbial communications in gram-positive and gram-negative bacteria by P. Srikanth, D. Sivakumar, J. Nouri

“…This may result in coordinated behaviours, including the development of biofilms, the generation of virulence factors, or other group activities. Without the ability to detect and react to the presence of their neighbours, microbial communities would not be able to adjust to changing environmental conditions or carry out collective actions that are essential for survival. …”

Major F plasmid clusters are linked with ColV and pUTI89-like marker genes in bloodstream isolates of Escherichia coli by Cameron J. Reid, Max L. Cummins, Steven P. Djordjevic

“…We hypothesise that their abundance in BSI E. coli is partially driven by carriage of backbone genes previously shown to contribute to virulence in models of bloodstream infection. Their carriage by pandemic E. coli STs suggests clonal expansion also plays a role in their success in BSI. …”
