Brett Smith for redOrbit.com - Your Universe Online Overuse of antibiotics in American agriculture and food production has long been a public concern over the potential for engendering more resilient microbes. A new study from Yale University shows that beneficial bacteria living in the gut of honeybees are demonstrating signs of resistance to such antibiotics. A genetic analysis of the digestive bacteria showed eight different resistance genes for the antibiotic tetracycline in samples...

Antibiotic Resistance Found In Ancient DNA

  A team comprised primarily of Canadian researchers has discovered antibiotic resistance in the DNA of 30,000-year-old bacteria found in the Yukon permafrost, various media outlets reported last week. The scientists, who published their findings in the journal Nature, note that resistant microbes are commonly thought to have developed after the development of synthetic antibiotics over 70 years ago. However, they discovered that it is not a "modern phenomenon," but is in fact "a...

When an antibiotic is consumed, researchers have learned that up to 90 percent passes through a body without metabolizing. This means the drugs can leave the body almost intact through normal bodily functions. In the case of agricultural areas, excreted antibiotics can then enter stream and river environments through a variety of ways, including discharges from animal feeding operations, fish hatcheries, and nonpoint sources such as the flow from fields where manure or biosolids have been...

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...
