↑ “Exclusive: Studies find 'super bacteria' in Rio's Olympic venues, top beaches”. Reuters. ngày 11 tháng 6 năm 2016. The second new study, by the Brazilian federal government's Oswaldo Cruz Foundation lab, which will be published next month by the American Society for Microbiology, found the genes of super bacteria in the Rodrigo de Freitas lagoon in the heart of Rio and in a river that empties into Guanabara Bay. Waste from countless hospitals, in addition to hundreds of thousands of households, pours into storm drains, rivers and streams crisscrossing Rio, allowing the super bacteria to spread outside the city's hospitals in recent years.
