reports reveal drug-resistant super bacteria identified as
carbapenem-resistant Enterobacteriaceae (CRE) have been found
in the waters of Rio de Janeiro where the 2016 Olympics
sailing events will be held.

doesnít mean they will become infected with these multi-drug
resistant organisms, but the presence of the bacteria is
certainly concerning," says Mayo Clinic infectious
diseases specialist Dr. Pritish Tosh.
most people talk about superbugs what they are referring to
are bacteria that are resistant to multiple kinds of
antibiotics," says Tosh. "For example, sexually
transmitted diseases, such as gonorrhea, have become resistant
to the routine antibiotics we would normally give. The term
superbug isnít very specific. It refers to a broader issue
we are having in medicine of bacteria becoming resistant to
routine antibiotics, making them much harder to treat. There
is more than one superbug. When people use the term superbug,
they are referring to any number of organisms that have become
resistant to a lot of antibiotics."
strains of bacteria that are resistant to carbapenem, a class
of broad-spectrum antibiotic used to treat severe infections,
as well as most other antibiotics.
of our newest classes of antibiotics, in a way, one of the
last lines of treatment for drug resistant bacteria are
carbapenem," Tosh says. "These are antibiotics used
to sometimes treat very severe infections. CRE are concerning,
because we know that people who are infected with CRE donít
respond as well to the antibiotics that they are given, have
more complications and die in larger numbers. Being exposed to
CRE doesnít mean you will become colonized with it or later
infected, but it does speak to other issues, such as
antibiotic overuse, especially in the developing world, where
you often do not need a prescription to get an

individually and also as a population. These
multi-drug-resistant organisms are proliferating because of
antibiotic overuse and misuse.
