Ancient Nubians Drank Antibiotic Beer?

A chemical analysis of the bones of ancient Nubians shows that they were regularly consuming tetracycline, most likely in their beer.

A chemical analysis of the bones of ancient Nubians shows that they were regularly consuming tetracycline, most likely in their beer. The finding is the strongest evidence yet that the art of making antibiotics, which officially dates to the discovery of penicillin in 1928, was common practice nearly 2,000 years ago.
The research, led by Emory anthropologist George Armelagos and medicinal chemist Mark Nelson of Paratek Pharmaceuticals, Inc., is published in the American Journal of Physical Anthropology.

“We tend to associate drugs that cure diseases with modern medicine,” Armelagos says. “But it’s becoming increasingly clear that this prehistoric population was using empirical evidence to develop therapeutic agents. I have no doubt that they knew what they were doing.”

Disrupting Bacterial Communications Could Compliment Antibiotics

Chatter between bacterial cells may stall healing of skin wounds, and sabotaging that chitchat could offer another way to battle infection, new research suggests.

Making Pseudomonas aeruginosa deaf to the molecular signals that the bacteria use to talk to each other would offer a kind of antibiotic therapy that doesn’t kill bacterial cells but rather strikes at their ability to attack human cells en masse, Jasper Jacobsen of the Statens Serum Institute in Copenhagen said May 24 at a meeting of the American Society for Microbiology.
