Lacticaseibacillus paracasei strain:normal tissue of gastric cancer patient | isolate:normal tissue of gastric cancer patient Genome sequencing. Lacticaseibacillus paracasei strain:normal tissue of gastric cancer patient | isolate:normal tissue of gastric cancer patient

The present invention provides a subspecies of Lactobacillus paracasei ZJUZ2-3 isolated from normal gastric tissue of human gastric cancer patients, which belongs to the animal subspecies with dominant abundance and is more representative under simulated gastric environment experimental conditions in vitro or in vivo (such as co culture). The above strain can be applied to gastric cancer research
