Abstract

The invention discloses a co-culture method for culturable anaerobic strains and pig intestine epithelial cells. The co-culture method comprises the following steps: measuring an optical density value of a bacterial solution by adopting a spectrophotometric method; determining the concentration of the bacterial liquid by adopting a plate counting method; determining the number of bacteria rapidly through correlation analysis of the two; and inoculating the accurately counted microorganisms to an intestinal epithelial cell line cultured in advance. According to the invention, the interference of various factors in other microorganisms or animal bodies can be eliminated, and the physiological functions of the microorganisms and the interaction mode of the microorganisms and host intestinal epithelial cells can be deeply analyzed.

Description

technical field

[0001] The invention belongs to the field of micro-ecological nutrition and physiology, and in particular relates to a method for co-culturing cultivable anaerobic strains and pig intestinal epithelial cells. Background technique

[0002] There are a large number of complex and diverse microbial flora inhabiting the intestinal tract of animals. A large number of studies have shown that intestinal microorganisms are closely related to the metabolism of nutrients, intestinal health and physiological conditions of the host. At present, amplicon sequencing or metagenomic sequencing is usually used to study the microbial composition and function of the gastrointestinal tract of animals, but these methods largely rely on bioinformatics methods, and the completeness of the reference database determines the accuracy of the analysis results. Correctness and precision, it is impossible to study the specific role of a certain bacterium in depth from the aspects of physi...
