Ancient tetracycline

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. . .

Tetracycline is produced by a soil bacteria called streptomyces, which is how it was discovered by modern society in the 1940s. Streptomyces thrives in warm, arid regions such as that of ancient Nubia, and likely contaminated a batch of beer. . .

“What they were making wasn’t like a Bud Light but a cereal gruel,” Armelagos said. “My students said that it was ‘not bad,’ but it is like a sour porridge substance. The ancient people would have drained the liquid off and also eaten the gruel.”
