Alterations of gut microbiota in cirrhotic patients with spontaneous bacterial peritonitis: A distinctive diagnostic feature.

Background: Spontaneous bacterial peritonitis (SBP) is a severe infection in cirrhotic patients that requires early diagnosis to improve the long-term outcome. Alterations in the gut microbiota have been shown to correlate with the development and progression of liver cirrhosis. However, the relationship between SBP and gut microbiota remains unknown.

[Fourier transform infrared spectroscopic study of Coprinus comatus].

In the paper, Fourier transform infrared (FTIR) spectroscopy was used to study the fruiting body of wild growing and cultivated Coprinus comatus and the cap of the mushroom before and after deliquescing into inky liquid. The results show that the infrared spectra of Coprinus comatus are mainly composed of the absorption bands of protein and polysaccharide. Remarkable differences are observed in the absorption bands of polysaccharide between the spectra of the wild growing and cultivated mushrooms, by which the wild growing and cultivated Coprinus comatus can be discriminated.
