Project description:Transcription profile of Escherichia coli cells in biofilms under static batch culture was compared to that of E. coli cells in planktonic cultures. Both E. coli biofilm and planktonic cultures were cultivated for 18 h in 10% Luria-Bertani broth at room temperature (20 degree Celsius). Biofilms were grown in static batch culture in petri dishes. Both planktonic culture and biofilms were homogenized and run through a separated protocol.

Both planktonic culture and biofilms were homogenized and run through a separated protocol. Two condition experiments: E. coli biofilm vs E. coli planktonic cultures. Two biological replicates with independently grown and harvested biofilms or planktonic cultures. Each biological replicate has two technical replicates of hybridization on microarray slides. Each slide has three built-in replicates for each probe.

Project description:Transcription profile of Escherichia coli cells in mono-species pure biofilms was compared to that of E. coli cells in E. coli-Stenotrophomonas maltophilia dual-species biofilms. E. coli cells were separated from dual-species biofilms before total RNA extraction to eliminate possible cross hybridization from S. maltophilia transcripts. The separation method was developed by combining the use of reagent RNAlater and immuno-magnetic separation. Pure E. coli biofilms were processed with the same separation protocol before RNA extraction.

Project description:We previously determined that loss of respiratory quinol oxidase cytochrome bd disrupts biofilm formation in uropathogenic Escherichia coli (UPEC). In this study, we extracted and interrogated the outer membrane and extracellular matrix of colony biofilms formed by UPEC isolate UTI89 and an isogenic mutant lacking cytochrome bd (∆cydAB).

Each slide has three built-in replicates for each probe.

Project description:Despite the characterization of many aetiologic genetic changes. The specific causative factors in the development of sporadic colorectal cancer remain unclear. This study was performed to detect the possible role of Enteropathogenic Escherichia coli (EPEC) in developing colorectal carcinoma.

Project description:Escherichia coli biofilms vs planktonic culture

Project description:The role of rpoS gene in the formation of Escherichia coli biofilms were investigated. The gene expression was compared among E. coli MG1655 wild type strain and rpoS knock-out strain in the biofilms, the planktonic exponential phase, and the planktonic stationary phase. The analysis revealed that the wild type bilfilms (WBF) showed similar pattern of gene expression with the WT planktonic stationary phase (WS), whereas the rpoS knock-out biofilms (MBF) showed similar pattern of gene expression with the wild type planktonic exponential phase (WE). Genes involved in the energy metabolism and the flagella synthesis showed higher expression in the rpoS knock-out biofilms (MBF), but not in the wild type biofilms (WBF). Moreover, genes involved in the stress responses showed higher expression in the wild type biofilms (WBF), but not in the rpoS knock-out biofilms (MBF). Keywords: cell type comparison (biofilms vs planktonic cells, wild type vs rpoS knock-out strains)
