Sexually transmitted diseases gonorrhea develops more and more resistance to all antibiotics, which we must deal with the United States, researchers warn.
In 2009, almost a quarter of the strains tested in a national gonorrhea surveillance project were resistant to penicillin, tetracycline, fluoroquinolones or a combination of these antibiotics which are typically used to treat the STD. And in early 2010 data is of another type of antibiotic resistance, cephalosporin. Is that those of cephalosporins are the only class of left to antibiotics that doctors recommend to treat the disease.
"This may be the harbinger of things to come", Dr. Kimberly Workowski, Centers for Disease Control and Prevention Division of STD prevention, said the early 2010 data. Workowski "resistance may get worse," said MyHealthNewsDaily.
If the resistance to cephalosporins develops, gonorrhea may develop in a Superbug and have a catastrophic effect on our ability to control the disease in the country, researchers say. A Superbug is a strain of bacteria that became resistant to antibiotics and is very difficult to kill. Other examples of Superbugs: Staphylococcus aureus resistant to Methicillin (MRSA) and some strains of tuberculosis.
Experts are working on strategies to prevent resistance to antibiotics, including the treatment of this disease with several antibiotics at a time. They also advocate safe sex and testing STD and ways to reduce the acquisition of gonorrhea.
Emerging antibiotic resistance
Gonorrhea is caused by the bacterium Neisseria gonorrhea and spreads through sexual activity. Individuals with gonorrhea show often no symptoms, but the disease can lead to serious complications, including infertility and chronic pelvic pain in women, and men epididymitis, a painful condition of testicular attached channels which can cause infertility treated, according to the CDC. If bacteria transmitted for blood or joints, the condition can be fatal, said the CDC.
More than 301,174 cases of gonorrhea were reported to the CDC in 2009, but the Agency estimated that more than 700,000 people become infected with the disease each year in the United States. It is most often infectious diseases which is must be reported to the Government of the United States.
Since the 1970s, the bacteria have become resistant to traditional antibiotics, including penicillin and tetracycline. In 1991, resistance to fluoroquinolones began to emerge. Researchers do recommend treatment with antibiotics now because once a bacterium has developed a resistance to a drug, that the resistance can develop quickly once more.
Researchers see the emergence of gonorrhea that is resistant to cephalosporin in Southeast Asia. In General, resistant strains of this part of the world migrate on the United States and then spread from West to East, Workowski said.
"The concern is that history tends to repeat itself," said Workowski. "It's the same principle has happened before."
How to prevent resistance
To prevent the emergence of cephalosporin resistance, the CDC is now recommending that the disease be treated with an injectable form of cephalosporin and a different kind of antibiotic such as azithromycin or doxycycline.
The CDC, in collaboration with the National Institutes of Health, is working to identify other drugs that could be used for profitable gonorrhea, including drugs that target the bacteria at different stages of the life cycle, said Workowski.
The organization also works to develop a plan for intervention in the event, said Workowski.
Pass it: Gonorrhoea could become much more difficult to treat if disease-causing bacteria develop resistance the last class of antibiotics, that we must fight it.
