Antibiotic Resistance Spreads Through Environment, Threatens Modern Medicine

Waste from people, pets, pigs and even seagulls may be playing a significant role in the rise of antibiotic-resistant infections, including methicillin-resistant Staphylococcus aureus (MRSA), a number of new studies warn.

Widespread fear of diminishing returns for modern medicine is becoming amplified, scientists say, by the discovery of soils and waterways polluted with both traces of antibiotics and bacteria encoded with antibiotic-resistant genes, the information that tells a microbe how to evade drugs designed to kill it. And even if that fortified microbe isn't capable of causing illness in humans itself, scientists add, its DNA could find its way into the more malignant microbes in the environment.        More Read
