Nubian antibiotic beer

Chemical analysis of the bones of ancient Sudanese Nubians who lived nearly 2000 years ago shows they were ingesting the antibiotic tetracycline on a regular basis, likely from a special brew of beer. The find is the strongest yet that antibiotics were previously discovered by humans before Alexander Fleming discovered penicillin in 1928.

“I’m going to ask Alexander Fleming to hand back his Nobel Prize,” joked chemist Mark Nelson, who works on developing new tetracyclines at Paratek Pharmaceuticals and is lead author of the paper published June in the American Journal of Physical Anthropology.

Nelson found large amounts of tetracycline in the bones tested from the ancient population, which lived in the Nubian kingdom (present day Sudan) between 250 A.D. and 550 A.D. and left no written record.

“The bones of these ancient people were saturated with tetracycline, showing that they had been taking it for a long time,” Nelson said in a press release August 30. “I’m convinced that they had the science of fermentation under control and were purposely producing the drug.”

“This discovery will provide a whole new framework for understanding the relationship between microbes and antibiotics,” said anthropologist Dennis Van Gerven of University of Colorado at Boulder. “There might have been other populations that were also doing the same thing, anywhere that there were these microbes. This is going to drive other scientists to start this search, and that is incredibly important.”

People have been using antibiotics for nearly 2,000 years, suggests a new study, which found large doses of tetracycline embedded in the bones of ancient African mummies.

What's more, they probably got it through beer, and just about everyone appears to have drank it consistently throughout their lifetimes, beginning early in childhood.

While the modern age of antibiotics began in 1928 with the discovery of penicillin, the new findings suggest that people knew how to fight infections much earlier than that -- even if they didn't actually know what bacteria were.

Some of the first people to use antibiotics, according to the research, may have lived along the shores of the Nile in Sudanese Nubia, which spans the border of modern Egypt and Sudan.

"Given the amount of tetracycline there, they had to know what they were doing," said co-author George Armelagos, a biological anthropologist at Emory University in Atlanta. "They may not have known what tetracycline was, but they certainly knew something was making them feel better."
