Essential proteins' dynamics in Streptococcus sanguinis under antibiotic effect.


ABSTRACT: The current project investigates the proteomic profiles of essential genes, mass spectrometric analysis respectively, under impact of sub-inhibitory concentration of ampicillin (0.125 micro gm/ml), to elucidate the S. sanguinis stress response mechanisms on a temporal basis and define “pathogenesis signatures” as potential therapeutic targets. We further believe that the current findings will help characterize a bacterial model for studying the dynamics of essential genes under clinically relevant stress factors (antibiotic treatment) and assist in designing evidence-based guidelines for treatment in clinical settings.

The paradoxical response of Streptococcus sanguinis to drugs prescribed for dental and clinical practices has complicated treatment guidelines and raised the need for further investigation. We conducted a high throughput study on concomitant transcriptome and proteome dynamics in a time course to assess S. sanguinis behaviour under a sub-inhibitory concentration of ampicillin. Temporal changes at the transcriptome and proteome level were monitored to cover essential genes and proteins over a phy  ...[more]
