SCIENTISTS have found a "superbug" strain of gonorrhoea in Japan that is resistant to all recommended antibiotics and said it could transform a once easily-treatable infection into a global public health threat.
The new strain of the sexually transmitted disease - called H041 - cannot be killed by any currently recommended treatments for gonorrhoea, leaving doctors with no other option than to try medicines so far untested against the disease.
Magnus Unemo of the Swedish Reference Laboratory for Pathogenic Neisseria, who discovered the strain with colleagues from Japan in samples from Kyoto, described it as both "alarming" and "predictable."
"Since antibiotics became the standard treatment for gonorrhoea in the 1940s, this bacterium has shown a remarkable capacity to develop resistance mechanisms to all drugs introduced to control it," he said.
In a telephone interview Unemo, who was to present details of the finding at a conference of the International Society for Sexually Transmitted Disease Research in Quebec, Canada, yesterday, said the fact that the strain had been found first in Japan also followed an alarming pattern.
"Japan has historically been the place for the first emergence and subsequent global spread of different types of resistance in gonorrhoea."
The team's analysis of the strain found it was extremely resistant to all cephalosporin-class antibiotics - the last remaining drugs still effective in treating gonorrhoea.
Gonorrhoea is a bacterial sexually transmitted infection and if left untreated can lead to pelvic inflammatory disease, ectopic pregnancy and infertility in women.
It is one of the most common STDs in the world and is most prevalent in south and southeast Asia and sub-Saharan Africa.
British scientists said last year that there was a real risk of gonorrhoea becoming a superbug - a bacteria that has mutated and become resistant to multiple classes of antibiotics - after reports of gonorrhoea drug resistance emerged in Hong Kong, China, Australia and other parts of Asia.
