Identificação de bactérias utilizando espectroscopia Raman ou FTIR e análise multivariada: Uma revisão sistemática

Abstract

As bacterial infections with resistant microorganisms become a problem that no longer exists today, it is necessary to investigate ways of detecting and identifying pathogens that offer quick, precise and accurate responses. In this context, Raman and FTIR spectroscopy associated with multivariate data analysis are widely explored, and many of these techniques are often proposed to return to more accurate methods, or to find them in a difficult area. Therefore, this work aims to determine which of the two spectral imaging techniques can be best applied to the identification of E. coli or S. aureus bacteria. For this reason, a search is carried out based on data from Web of Science and Scopus, with a strategic search focused on tools that we will use as shown by the bacteria of interest for Raman or FTIR spectroscopic analysis and multivariate data analysis. As the next stages of trial eligibility, we will follow the PRISMA protocols, at the end of the process in which the articles were chosen for analysis by systematic review. The quality of the articles was validated and based on our results from this validation, even without checking the risks, we concluded that the Raman technique is more suitable for identifying bacteria than FTIR.
