Resilience of agricultural soils to antibiotic resistance genes introduced by agricultural management practices

چکیده
Antimicrobial resistance (AR) represents a global threat in human and veterinary medicine. In that regard, AR proliferation dissemination agricultural soils after manure application raises concerns on the enrichment of endogenous soil bacterial population with allochthonous antibiotic genes (ARGs). Natural resilience background concentrations ARGs play key roles mitigation propagation natural environments. present study, we carried out longitudinal sampling campaign for two crop vegetation periods to monitor spatial temporal changes abundance seven clinically relevant (sul1, ermB, vanA, aph(3')-IIa, aph(3′)-IIIa, blaTEM-1 tet(W)) ribosomal 16S RNA. The absolute relative abundances selected were quantified total community DNA extracted from (manured non-manured) forest soils, fresh pig faeces slurry. We observed ARG return levels manure-induced exposure within growing season, highlighting capacity soil. Naturally occurring high can be found due distance under low anthropogenic influences. It was pesticide increases three tested (ermB, aph(3′)-IIIa tet(W)). Moreover, noticed sul1, ermB show an increase by 100- 10,000- fold, maturation manure. Outcomes our study suggest environments strong alleviate externally induced disturbances concentrations. are also impacted represented indigenous resistome.

4 CSA News June 2014 related to ABR, from the development of superbugs like methicillin-resistant Staphylococcus aureus (MRSA) to speculation about the overuse of biocides like triclosan in hand soaps. A report published in 2000 by the World Health Organization (WHO) identified ABR as one of the most critical human health challenges of the 21st century. The report observed that more than two mi...
متن کاملPlant agricultural streptomycin formulations do not carry antibiotic resistance genes.
Streptomycin is used in plant agriculture for bacterial disease control, particularly against fire blight in pome fruit orchards. Concerns that this may increase environmental antibiotic resistance have led to bans or restrictions on use. Experience with antibiotic use in animal feeds raises the possible influence of formulation-delivered resistance genes. We demonstrate that agricultural strep...
متن کاملEffect of Treated Wastewater Irrigation on the Proliferation of Antibiotic Resistance in Agricultural Soils
In Israel with its semi-arid climate, water is a limited resource and yet, in the last two decades about 60% of all of Israel’s water resources are directed for agricultural use. This is feasible due to the capacity to recycle water. Treated wastewater (TWW) has become an important source of irrigation water in Israel and other parts of the world due to the pressures of increasing population an...

Application of animal manures to soil as crop fertilizers is an important means for recycling the nitrogen and phosphorus which the manures contain. Animal manures also contain bacteria, including many types of pathogens. Manure pathogen levels depend on the source animal, the animal's state of health, and how the manure was stored or treated before use. Rainfall may result in pathogen spread i...
