Researchers at the University of Texas in the US have for the first time succeeded in keeping the corkscrew-like syphilis bacterium alive for longer.
The bacterium survived in a rabbit cell on a combination of vitamins and sugars, and the researchers now hope to develop a vaccine against it.
Syphilis is primarily a problem in African countries, where the bacteria causes many deaths and miscarriages.

The bacterium that causes gonorrhea is resistant to almost any type of antibiotic.
However, the new drug zoliflodacin has shown good results in clinical tests, with 96 percent of patients cured.
Annually, around 80 million people are infected with the bacteria, which can make babies blind and women infertile.

British researchers have discovered that the HSV2 herpes virus, which causes wounds around the genitals, was most likely transferred from our chimpanzee ancestor to our own ancestor about two million years ago.
The meat of the chimpanzee was eaten by the humanoid Parathropus boisei, which in turn was eaten by our ancestor Homo erectus.

American researchers have found the enzyme that the chlamydia bacterium uses to deceive its host cell.
The enzyme ensures that the cell forms a protective protein shield around the bacterium and disrupts the ability of the cell to render invading organisms harmless.
The researchers now want to develop a drug that blocks this enzyme.
