| Abstract |
Stenotrophomonas maltophilia is a Gram-negative bacterium commonly isolated from nosocomial infections. Analysis of the genome of the clinical S. maltophilia isolate K279a indicates that it encodes a diffusible signal factor (DSF)-dependent cell-cell signaling mechanism that is highly similar to the system previously described in phytopathogens from the genera Xanthomonas and Xylella. Our objective was to study the function of DSF signaling in the clinical strain S. maltophilia K279a using genetic and functional genomic analyses. We compared the wild-type strain with a mutant deficient in the rpfF (regulation of pathogenicity factors) gene that is essential for the synthesis of DSF. The effects of disruption of DSF signaling were pleiotropic with an impact on virulence, biofilm formation and pathogenesis. The phenotypic effects of rpfF mutation in S. maltophilia could be reversed by addition of exogenous DSF. Taken together, we demonstrate that DSF signaling regulates factors contributing to virulence, biofilm formation and motility of this important opportunistic pathogen. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 13 August 2018.
All research outputs
#20,663,600
of 25,385,509 outputs
Outputs from BMC Research Notes
#3,261
of 4,514 outputs
Outputs of similar age
#265,259
of 341,333 outputs
Outputs of similar age from BMC Research Notes
#111
of 149 outputs
Altmetric has tracked 25,385,509 research outputs across all sources so far. This one is in the 10th percentile – i.e., 10% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,514 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.1. This one is in the 15th percentile – i.e., 15% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 341,333 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 12th percentile – i.e., 12% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 149 others from the same source and published within six weeks on either side of this one. This one is in the 18th percentile – i.e., 18% of its contemporaries scored the same or lower than it.
