German scientists of [b]Helmholtz Zentrum[/b] in a joint study with researchers of [b]Julius Kühn Institute[/b] have found that the repeated application of manure contaminated with antibiotics changes the composition of bacteria in the soil. The focus of the investigation was on [b]sulfadiazine[/b], a widely used antibiotic in animal husbandry, which enters the soil via manure. The researchers report that repeated application of the antibiotic leads to a decrease in beneficial soil bacteria and at the same time an increase in bacteria that are harmful to humans.
