Science helps solve stomach ulcers in cattle

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.

Water proof bacteria inspire special coatings

Edinburgh - A study into how bacteria protect themselves, by forming a type of waterproof raincoat, could lead to a new generation of products designed to protect crops from disease.

Immune cells help beneficial bacteria triumph over bad

The immune system helps to shape the balance of good or bad bacteria in the human gut. Researchers have found a protein on white blood cells affects the balance of the microorganisms in the gut.

Sister species to leprosy bacterium discovered

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.

Fund launched to fight global resistant infections

A new global campaign has been launched called the Fleming Fund, with the aim of harnessing resources to tackle the growing problem of antibiotic resistant pathogenic bacteria.

Soil microbes influence grape and wine quality

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.

Skin of a frog determines its disease susceptibility

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.

Preventing antibiotics from killing beneficial bacteria

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.

Will we soon see an anti-obesity drug?

Scientists have re-programmed bacteria to generate a molecule that can function as a hunger-suppressing lipid. So far, the molecule has proved successful in rodent studies.

Are our gut bacteria swapped when we snuggle up?

Paris - 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.

Ebola-proof Android tablet helps aid workers in West Africa

Google has developed an Ebola-proof tablet for use by health workers in Sierra Leone. It can resist the storms and high humidity of West Africa and can be dipped into antibacterial chlorine after use.

Powerful molecule can hunt down deadly bacteria

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.

Connection with bacteria found in sewage and weight gain

According to new research, a link was found between microbes identified in a city’s sewage treatment plants and the population’s obesity rate.

Experts say beards breed disease

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?

Medical equipment cleaning risks are extensive

The number of deaths connected to certain medical probes contaminated with pathogens may go beyond a recent outbreak in Los Angeles.

Bacteria are small, but how about ultra-small bacteria?

Microbiologists have captured in-depth microscopy images of ultra-small bacteria. These are the smallest bacteria ever identified.

New mechanism found for blocking HIV

A synthetic antibody has been developed. The antibody, based on laboratory tests, prevented infection in four monkeys injected with heavy doses of the HIV virus.

Scientists discover how C. diff disrupts the human gut

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.

Using a probiotic to cure rainbow trout disease

Rainbow trouts are vulnerable to Coldwater Disease, a type of bacterial infection. To combat the disease, researchers have developed a probiotic using bacteria from the trout’s own gut.

Using bacteria to battle malaria as possible drug treatment

Uppsala - A newly discovered family of bacteria, found in malaria-carrying mosquitoes, could hold the key to fighting the parasitic disease.

Newly identified risk of antibiotic overuse

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.

Mothers pass traits to offspring via bacterial DNA

A remarkable study suggests that the DNA of bacteria that live in the body can pass a trait to offspring in a way similar to the parents' own DNA. This is based on studies conducted using mice.

Oral bacteria play a role in promoting cancer

Tel Aviv - Bacteria found in the mouth are more prevalent in patients with colon cancer. It seems that these bacteria protect a variety of tumor cells from being killed by immune cells. This finding could lead to new treatments in cancer.

Doubt cast on gut bacteria triggering obesity

San Jose - Some science studies indicate that the gut microbiome is the cause of obesity. However, one microbiologist is challenging this and says it is not so simple.

Gut microbes linked to Type I diabetes

In a major study scientists have confirmed a connection between changes in gut microbes and the onset of type 1 diabetes. The research tracked infants over a long period of time, in order to demonstrate the relationship.

Breastfeeding prepares a baby for solid food

New research has discovered that a baby’s diet during the first few months of life influences the microbes in the baby’s gut. In turn, this influences baby’s ability to move from milk to solid foods and it could also affect health in later life.

Drug resistant bacteria lurking in New York subways

A new study has shown that New York City's subway system is crowded with microbes that are resistant to two widely used antibiotics.

New York subway infested by deadly bacteria and mystery DNA

New York - Researchers have found that the New York City subway system infested with dangerous microorganisms and bacteria, some potentially deadly to human beings.

New protein detonates bacteria from within

Tel Aviv - By sequencing the DNA of bacteria resistant to viral toxins, scientists have identified novel proteins capable of stymieing growth in pathogenic, antibiotic-resistant bacteria.

Immune system can promote good gut health

Part of the body’s immune system called MyD88 is responsible for promoting a healthy colony of good bacteria. The more "good" bacteria, the better the digestive health. A new study has explored this further.
