PCR-DGGE法分析婴儿肠道菌群多样性
Diversity analysis of infant intestinal microflora by using PCR-DGGE
摘要
Abstract
Purpose: The diversity of the infant intestinal microflora was analyzed by using the PCR-DGGE, providing theoretical basis for the application of probiotics in infant formula milk powder. Method: The universal primer of the bacterial 16S rDNA-V3 region was used as primer and the total DNA of food-bome diarrhea infants and health infants stool samples were used as a template. After PCR amplification, DGGE analysis was performed. Result: The DGGE profiles of the 30 stool samples were highly polymorphic. The diversity of the food-borne diarrhea infants was significantly different with healthy infants, and the Food-bome diarrhea infants had a lower intestinal diversity. By cluster analysis and similarity analysis, Can be drawn that the similarity of intestinal microflora of food-borne diarrhea infants was higher, and the intestinal microflora of food-bome diarrhea infants and healthy infants had obvious differences. Conclusion: PCR-DGGE technology can preliminary analyze the diversity of the infant intestinal microflora, providing theoretical basis for the application of probiotics in infant formula milk powder.关键词
