Phage preparation is an advanced preparation type at present, and it is the most important application to regulate human intestinal flora by phage. The FDA also approved the application for clinical trials of phage preparations, and some phage preparations have been used in the food industry. Floraphage is a highly active composite phage preparation developed and produced by Arthur Andrew Medical Company of the United States. It is the first compound probiotic preparation in the world and has passed the FDA certification. Decompose intestinal specific pathogenic bacteria, support the proliferation of beneficial bacteria, deeply solve digestive tract problems such as chronic enteritis, colitis, chronic diarrhea, chronic constipation, irritable bowel syndrome, and urethritis, cystitis, vaginitis, pelvic inflammatory disease, prostatitis and other problems caused by 19 pathogenic Escherichia coli, and achieve the best immunity and digestive health.
There is no report on the research of phage preparation and drug declaration in China. The application of food preservatives, agriculture, animal husbandry, fishery and other industries has not been reported. Because the technology is relatively new and the use cost is relatively high, its application in China is inevitably not very wide, and it will take several years to make greater progress.
Moreover, antibiotics are still the mainstream antibacterial products at present, with low cost, convenient use and wide antibacterial spectrum. Except for drug resistance, it is superior to phage preparation in other aspects. When antibiotic resistance becomes an urgent need one day, it will be the spring of phage preparation.
