Immune bacteria Antibiotics Found in Cave Aged 4 Million Years

Immune bacteria Antibiotics Found in Cave Aged 4 Million Years - Scientists discover bacteria that completely immune alias does not work is treated with antibiotics. Bacteria were found at a depth of 400 meters (about 1,300 feet) below the surface of the earth in a cave which has 4 million years old.

Isolated cave was named Lechuguilla in New Mexico. The discovery of these bacteria may provide clues to the development of drugs to combat superbug today.

"It's still a big question, Where did these bacteria came from? Almost no one had thought to look at other bacteria which may not always cause disease," says study leader Gerry Wright, a chemical biologist at McMaster University, Ontario as reported by Fox News, Friday (13/04/2012).

Overuse of antibiotics by hospitals and farms have been widely criticized because it led to bacterial strains resistant to antibiotics.

However, because of Lechuguilla Cave has long been untouched, the existence of ancient bacteria that indicate the presence of drug resistance has actually happened a long time and evolved millions of years ago.

Samples of bacteria in the cave, which is found in pure crystals not infect humans, but has the capacity to fight against synthetic drugs in modern times.

Researchers examined 93 species of bacteria extracted from the cave and mengujikannya on 26 different types of antibiotics. About 70 percent of these bacteria are resistant to three or four classes of antibiotics. Three of the strains of the bacteria - which is also a distant relative of anthrax - were resistant to 14 of the 26 antibiotics tested.

"The science of clinical microbiology has long become confused. When you bring a new antibiotic in the hospital, resistance will inevitably emerge shortly afterwards, either in a matter of months to years," said Wright.
