The waters of Rio Carioca, in which scientists discovered a new bacteria, are pictured running into the Guanabara Bay in Rio de Janeiro December 16, 2014. Scientists at a Rio de Janeiro research institute have found what they call a new "super-bacteria" that is resistant to antibiotics in the waters where sailors will compete in the Olympic sailing events in 2016. The bacteria is normally found in hospital waste and can cause urinary, gastrointestinal and pulmonary infections, officials with the Oswaldo Cruz Foundation said on Monday.
