Studies from University of Munich in the Area of Urinary Tract Reported

May 30, 2014

By a News Reporter-Staff News Editor at Health & Medicine Week -- Investigators discuss new findings in Urinary Tract. According to news originating from Munich, Germany, by NewsRx correspondents, research stated, "Based on molecular-specific surface-enhanced Raman scattering (SERS) spectroscopy we were able to discriminate between rough and smooth strains of Escherichia coli and Proteus mirabilis bacteria. For this purpose, bacteria have been immobilized through electrostatic forces by inducing a positive charge on the glass slide."

Our news journalists obtained a quote from the research from the University of Munich, "This way, SERS spectra on bacterial biomass and also on single bacteria could be recorded in less than 2 h, by using concentrated silver nanoparticles as SERS-active substrate. Single-bacterium SERS spectral fingerprints showed to be sensitive to the presence of the O-antigen at strain level and to the microorganisms growth phase."

According to the news editors, the research concluded: "By using principal component analysis (PCA) on the SERS spectra recorded from E. coli and P. mirabilis, these two uropathogens could be fairly discriminated."
