Social campaign group Avaaz is seeking to reduce the amount of antibiotics administered to farm animals. The group points out that the use of these drugs has fallen in Europe, with the exception of some territories like the U.K.
Despite calls to restrict the use of antibiotics, in order to stem the tide of antibiotic resistance, a new report shows that around three-quarters of the countries in the world have no plans to slow-down on antibiotic use.
Researchers looking into whether stomach ulcers in cattle are related to the presence of certain bacteria (as is the case with humans). They found that this not the case. This could lead to alternative treatments for livestock.
Scientists from Switzerland have genetically sequenced the bacterium that causes most cases of leprosy. At the same time they are the first scientists to unravel a sister species that causes a rare form of the disease.
Researchers have studied the microbial composition of a wine grapevine. The examination unearthed the fact that the microbes found in grapes, on leaves and flowers are derived from the microbes found in the plant's roots.
The relationships between microbial communities on skin and amphibian disease resistance have been explored. This is in relation to combating a frog-killing fungus called Batrachochytrium dendrobatidis.
The microorganisms in the human gut can help the body to maintain a state of health. One problem with antibiotics, when used to fight pathogens, is that they can indiscriminately kill off beneficial bacteria. A new compound can help address this concern.
The microorganisms that reside in the guts influence a number of health outcomes. There are variations between people. One source of the variation might be the extent of “personal relationships”, according to a new study.
Scientists have modified two lipids (fats) and produced a new bio-chemical method to label pathogenic bacteria. This enables the bacteria to be selectively targeted with antibiotics while protecting healthy cells.
Some medical experts are describing beards as "bacterial sponges." They say facial hair can spread infections and disease. Others disagree and say they're no more dangerous than clean shaven. So what's the truth?
Scientists have determined how Clostridium difficile causes harm in the guts of animals and people in a relatively short time frame. It is hoped that the findings will help treat severe diarrhea in patients.
Scientists are warning that some antibiotics can have an unintended impact on the microorganisms that live in an animal's gut. Ultimately this can affect the immune system, glucose metabolism, food absorption, obesity, stress and behavior.

This key experiment shows the successful protection of a phage-sensitive bacterial strain against a virus. Top-right - bacteria growing in the absence of a virus; Top-left - holes in the culture caused by an infecting virus; Bottom - when equipped with specific CRISPR defense system components, the bacteria became resistant to the virus.
