Cattle-associated antibiotics disturb soil ecosystems

Virginia Tech team finds amount of antibiotic-resistant genes was 200 times greater in soil near cattle manure piles.

Manure from cattle administered antibiotics drastically changes the bacterial and fungal make-up of surrounding soil, according to a Virginia Tech research team.

The team analyzed soil samples from 11 dairy farms in the U.S. and found that the amount of antibiotic-resistant genes was 200 times greater in soil near manure piles compared with soil that wasn’t near the piles.
