Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy and Artificial Neural Networks Applied to Differentiate Escherichia coli papG+papG- Strains

Abstract EN

Fimbriae are an important pathogenic factor of Escherichia coli during development of urinary tract infections.

Here, we describe a new method for identification of Escherichia coli papG+ from papG- strains using the attenuated total reflectance Fourier transform infrared Spectroscopy (ATR FT-IR).

We applied artificial neural networks to the analysis of the ATR FT-IR results.

These methods allowed to discriminate E.

coli papG+ from papG- strains with accuracy of 99%.
