Recently, a research report "Distribution and Quantification of Antibiotic Resistant Genes and Bacteria across Agricultural and Non-Agricultural Metagenomes." Published in the international journal PLoS One revealed the genes of bacterial antibiotic resistance across agricultural and non-agricultural fields Distribution and quantitative situation.
The study was carried out by researchers in the management of agricultural ecosystems in the United States. The researchers pointed out that the antibiotic resistance of bacteria can be transferred from animals to humans through the food chain, so the specific antibiotic resistance bacteria and genes carried by the body are between The relationship needs to be clarified. The ecological relationship between antibiotic resistance genes and bacteria in food production systems is currently unclear, or compared to other ecosystems, the status of antibiotic resistance genes in food animals is not clear.
In this study, the researchers reported the distribution of antibiotic resistance genes in publicly available agricultural and non-agricultural samples, and identified which bacteria are more likely to carry these resistance genes. Compared with seafood and Antarctic samples, there are a large proportion of antibiotic-causing genes in samples related to the gastrointestinal tract and agricultural products. Although antibiotic resistance genes are a natural part of human influence and the original existence of common habitats, the existence of these resistance genes in special habitats is not enough to reveal the use of antibiotics in human origins.
The researchers emphasize that the basic research and controllable samples are to study the natural background level of antibiotic-resistant bacteria or genes. At the same time, the researchers also hope to conduct in-depth research to reveal whether the biological characteristics of each bacteria are possible through the food chain Make the transfer.
