Enteric pathogens and Carbapenem resistance genes are widespread in the fecal contaminated soils of cattle farms in the United States

Cattle farming is considered a major contributor to antibiotic resistant (AR) genes and bacteria in nearby environments, predominantly due to the large amount of manure released by cattle to soils. This study sought to compare soil within and outside of cattle pens from seven farms in the US. Soil m...
