The role of broad-host range IncP-1ε plasmids in the dissemination of antibiotic resistance in agricultural systems has not yet been investigated. These plasmids were detected in total DNA from all of 16 manure samples and in arable soil based on a novel 5'-nuclease assay for real-time PCR. A correlation between IncP-1ε plasmid abundance and antibiotic(More)
Two soils were amended three times with pig manure. The abundance of sulfonamide resistance genes was determined by quantitative PCR 2 months after each application. In both soils treated with sulfadiazine-containing manure, the numbers of copies of sul1 and sul2 significantly increased compared to numbers after treatments with antibiotic-free manure or a(More)
BACKGROUND Larvae of the Western Corn Rootworm (WCR) feeding on maize roots cause heavy economical losses in the US and in Europe. New or adapted pest management strategies urgently require a better understanding of the multitrophic interaction in the rhizosphere. This study aimed to investigate the effect of WCR root feeding on the microbial communities(More)
Veterinary antibiotics entering agricultural land with manure pose the risk of spreading antibiotic resistance. The fate of sulfadiazine (SDZ) introduced via manure and its effect on resistance gene levels in the rhizosphere were compared with that in bulk soil. Maize plants were grown for 9 weeks in soil fertilized with manure either from SDZ-treated pigs(More)
Multiple antibiotic resistant bacterial pathogens pose a major threat for the successful therapeutic use of antibiotics in human and veterinary medicine. Veterinary antibiotics used in animal husbandry are assumed to contribute to an increased antibiotic resistance among bacteria in manure. Bacteria carrying transferable antibiotic resistances, antibiotics,(More)
