ScienceDaily (July 10, 2011) — An international research team has discovered a strain of gonorrhea resistant to all currently available antibiotics. This new strain is likely to transform a common and once easily treatable infection into a global threat to public health.
The details of the discovery made by Dr. Magnus Unemo, Dr. Makoto Ohnishi, and colleagues will be presented at the 19th conference of the International Society for Sexually Transmitted Disease Research (ISSTDR) which runs July 10-13 in Quebec City, Canada.
The team of researchers successfully identified a heretofore unknown variant of the bacterium that causes gonorrhea, Neisseria gonorrhoeae. Analyzing this new strain, dubbed H041, allowed researchers to identify the genetic mutations responsible for the bacterium's extreme resistance to all cephalosporin-class antibiotics -- the last remaining drugs still effective in treating gonorrhea.
"This is both an alarming and a predictable discovery," noted Dr. Unemo of the Swedish Reference Laboratory for Pathogenic Neisseria. "Since antibiotics became the standard treatment for gonorrhea in the 1940s, this bacterium has shown a remarkable capacity to develop resistance mechanisms to all drugs introduced to control it."
