Scientists have found that ancient Sudanese Nubians who lived almost 2000 Years back have had a specially brewed beer which had tetracycline (an antibiotic) which can help against many diseases like Rocky Mountain spotted fever (Rickettsia), Q fever (Coxiella), Psittacosis and Lymphogranuloma venereum (Chlamydia), and to eradicate nasal carriage of meningococci. Tetracycline tablets were used in the plague outbreak in India in 1992. Doxycycline is also one (of many) recommended drugs for chemoprophylatic treatment of malaria in travels to areas of the world where malaria is endemic.
Tetracyclines are bacteriostatic antibiotics that bind to the 30S subunit of the ribosome, thus inhibiting bacterial protein synthesis. Hence can be found in bones. Even Sudanese Nubians children mummies were found to have tetracycline in their bones.
