AI Article Synopsis
- * Researchers examined 27 fecal samples from three groups: coeliac patients, coeliac patients on a gluten-free diet, and a control group, employing both SERS spectroscopy and 16S rRNA sequencing for characterization.
- * Significant differences were observed in SERS spectra between coeliac patients and those on a gluten-free diet, particularly with higher levels of xanthine and hypoxanthine in the latter; however, these differences were not linked to variations in
Article Abstract
Surface-enhanced Raman scattering (SERS) spectra of faecal samples can be obtained by adding AuNP to their methanol extracts according to the reported protocol, and display bands that are due to bilirubin-like species but also to xanthine and hypoxanthine, two metabolic products secreted by gut bacteria. A total of 27 faecal samples from three different groups, i.e. coeliac patients (n = 9), coeliac patients on gluten-free diet (n = 10) and a control group (n = 8), were characterized with both SERS spectroscopy and 16S rRNA sequencing analysis. Significant differences are present between SERS spectra of coeliac patients and those on gluten-free diet, with a marked increase in the relative intensity of both xanthine and hypoxanthine for the latter. Interestingly, these differences do not correlate with bacterial composition as derived from 16S rRNA sequencing.
