WILD NEW JERSEY: Jill's Pick from Around the World: Sharks Carrying Drug-Resistant "Bacterial Monsters"

Story from NationalGeographic.com: Our leftover medicines are spawning drug-resistant "bacterial monsters" that thrive inside sharks, scientists say. The finding suggests antibiotics such as penicillin may be leaching into the environment and spurring drug-resistant bacteria to evolve and multiply in the oceans.

"Bacteria have sex, basically. They can transfer genetic material," said study leader Mark Mitchell, professor of veterinary clinical medicine at the University of Illinois at Urbana-Champaign. Mitchell and colleagues found antibiotic-resistant bacteria in seven species of shark—such as bull sharks, lemon sharks, and nurse sharks—as well as the redfish Sciaenops ocellata.
