Soil animals have a large number and variety, which plays a key role in soil ecosystem.
on the other hand, intestinal microorganisms play an important role in the health of the host, and intestinal microbiomes in soil animals are an important part of the soil microbiome, but people's understanding of intestinal microbiomeinis in soil animals is very lacking.
with the intensification of human activities, a large number of pollutants into the soil ecosystem, their impact on soil animals has attracted widespread attention.
but the effects of pollutants on gut microbes in soil animals remain unclear.
improve the understanding of genetic diversity of resistance in the intestines of soil animals, and help to understand the transmission and influence of resistance genes in soil food web.
urban soil and biogeochemical research group of the Institute of Urban Environment of the Chinese Academy of Sciences, through high-throughput sequencing and high-throughput quantitative PCR technology, the first set up the soil animal jumping gut microbe extraction method, found that the concentration of antibiotics can significantly reduce the abundance, composition and diversity of soil animal stoic intestinal microbes, significantly increase the abundance and diversity of resistance genes (see figure).
these results can help raise awareness of the risks of intestinal microbes and resistance genes in soil animals being transmitted through soil food webs.
the results of the study were published in Environmental Science and Technology (EST; DOI: 10.1021/acs.est.est.7b04292) under the title of The Antibiotics Disturb the Microbiome and The Story of the Day the Resistance Genes in the Gut of the A Common Soil Collembolan (EST; DOI: 10.1021/acs.est.7b04292).
the research has been supported by the National Natural Science Foundation of China, the Chinese Academy of Sciences pilot science and technology special Category B and international cooperation and exchange projects.
