New MRSA superbug emerges in Brazil
Date:4/17/2014

ted microbiological and genetic analyses of an MRSA superbug recovered from the blood of a 35-year-old Brazilian man and identified a novel transferable genetic element (plasmid) that carries the genes necessary for vancomycin resistance (vanA gene cluster).

"The presence and dissemination of community-associated MRSA containing vanA could become a serious public health concern," report the authors in the paper.

However, since this is the only documented case of this type of infection, Arias said, it is too early to tell if this specific superbug will lead to a bigger threat.

Barbara E. Murray, M.D., report co-author and director of the Division of Infectious Diseases at the UTHealth Medical School, said, "The worst resistance possible has now appeared in the community-associated MRSA clone."

What is the next step?

"There will have to be increased surveillance in South America and worldwide in the future," said Murray, who is the holder of the J. Ralph Meadows Professorship in Internal Medicine at the UTHealth Medical School and president of the Infectious Diseases Society of America.
