Antibiotics use affects the abundance of resistant bacteria in soil: The use of animal manure increases the soil content of antibiotic-resistant genes

Antibiotics use affects the abundance of resistant bacteria in soil: The use of animal manure increases the soil content of antibiotic-resistant genes: When a certain type of antibiotic is phased in, the abundance of resistant genes in soil increases, new investigations show. When the antibiotic is phased out again, the abundance of resistant genes drops - and this happens relatively quickly. The scientists also found a correspondence in time between the first detection of antibiotic resistance in the health service and the detection of such genes for resistance in soil that had received applications of animal manure.
