Gonorrhea Acquires Human DNA

Bacteria have been known to swap and acquire DNA from other bacteria, which increases biodiversity that can be beneficial for survival. However, what was previously thought impossible has been proven false. New research from Northwestern University has found a piece of human DNA in the genome of Neisseria gonorrhoeae, the bacteria that causes the human sexually transmitted disease gonorrhea. This is the first time that a direct transfer of genetic material from human to bacteria has ever been recorded. This finding reveals clues to how the bacteria has adapted so well to survival among humans. Gonorrhea is a disease that is exclusive to humans and is transmitted via sexual contact. Each year approximately 50 million people worldwide become infected with the disease. The U.S. sees about 700,000 cases annually. Treatment is available by way of antibiotics. However, because of the ability of the bacteria to change and adapt, it has now developed resistance to the majority of antibiotics. Scientists are now interested in finding out what the bacteria is doing with their newly acquired human DNA. [via Medical News Today]
