This just in from the Washington Post--— A drug-resistant “super bacteria” that’s normally found in hospitals and is notoriously difficult to treat has been discovered in the waters where Rio de Janeiro’s Olympic sailing events will be held, scientists said Monday.
The Instituto Oswaldo Cruz, Brazil’s most respected health research institute, said it has discovered bacteria that produce an enzyme that make it resistant to most forms of treatment in water samples taken from various spots along the Carioca River. Among the spots is where the river flows into the city’s Guanabara Bay, site of the 2016 sailing and wind surfing events.
Bacteria with the so-called KPC enzyme are difficult to treat. The institute said no instances of infection resulting from the contaminated water have yet been detected but warned of possible danger to swimmers.
“The illnesses caused by these microorganisms are the same as those caused by common bacteria, but they require stronger antibiotics and, sometimes, can require hospitalization,” the study’s coordinator, Ana Paula D’Alincourt Carvalho Assef, wrote in an email to The Associated Press. “Since the super bacteria are resistant to the most modern medications, doctors need to rely on drugs that are rarely used because they are toxic to the organism.”
“Carriers can take these resistant bacteria back to their own environments and to other people, resulting in a cycle of dissemination,” said the institute, which is affiliated with Brazil’s Health Ministry.
With some 70 percent of sewage in this city of 12 million going untreated — and flowing, raw, into rivers, onto beaches and into the Guanabara Bay — water quality has been a major worry ahead of the 2016 summer games. In their Olympic bid, organizers pledged to slash by 80 percent the amount of sewage and garbage that’s pumped into the bay daily, but critics insist little has been done.
