Smallest ever bacteria discovered

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.

Tackling cocaine addiction with bacteria-protein cocktail

In a new study, a modified bacterial protein is able to trigger a robust immune response against a cocaine-linked molecule in mice. The creators hope it will stop addicts from taking the drug.

Hoopoes engage in strange egg-licking behaviors

Hoopoes have a remarkable habit. They cover their eggs with a secretion from their beaks. The secretion is packed with beneficial bacteria, which protects the eggs. A new research study has been looking into this behaviour further.

Unpacking the clues as to why some bacteria resist antibiotics

Phoenix - Scientists are seeking to find out the different processes used by bacteria to survive destruction from antimicrobial peptides within the natural environment. The hope is to find new ways to kill pathogenic organisms.

Gut bacteria influence Crohn's disease, ulcerative colitis

New research suggests that a person’s specific genes influence whether intestinal bacteria will trigger inflammatory bowel diseases. Understanding such causes is provides knowledge to help with prevention and treatment.

The bacteria in your gut may help you destress, says new research

A recent study has found a link between the kind of bacteria you have in your gut and your mental anxiety levels. This throws up some interesting questions in the study of anxiety relief.

Five startling hygiene facts

Health and hygiene are important issues and often need to go hand-in-hand in order to minimize the risk of infection. Have you ever wondered what the top five stomach churning hygiene facts might be?

Op-Ed: The myths around Teixobactin

The breaking science news story of the week has been the announcement of a new antibiotic called Teixobactin and its apparent "superbug" battling qualities. Although welcome, it is important to consider the antibiotic itself beyond the hyperbole.

New probiotic hope for autoimmune diseases

Newcastle - Certain bacteria that can eat their way through yeast in the human gut could be the basis for new treatments for people suffering from bowel diseases, according to some new research.

New discovery could help protect the bees

Etymologists have made a new discovery to combat a disease that has been savagely killing global honeybee populations. The scientists took a toxin released by the pathogen that causes American foulbrood disease and developed an inhibitor against it.

Bacteria can be used to manufacture terpenes

Bacteria are a source of terpenes. These are natural compounds used to make drugs, food additives, perfumes, and other useful products. Research indicates that there could be other terpene products, as yet undiscovered, hiding in the genomes of bacteria.

Extraordinary bacteria use energy in its purest form (video)

Bacteria to survive on a variety of energy sources. Nonetheless, scientists were surprised recently to discover new species of bacteria that can survive and function on electricity alone.

Op-Ed: Microbiology in the news, the top stories of 2014 Special

London Colney - The website Pharmaceutical Microbiology has reviewed the top ten microbiology stories and events that have made the news during 2014.

A 10-second kiss transfers 80 million bacteria, study says

A research study from institutes in the Netherlands reports that a couple will share approximately 80 million bacteria during a 10-second kiss!

Parkinson’s disease linked to gut bacteria

A new strand of research shows that people suffering from Parkinson’s disease have a different composition of bacteria in their intestines compared with normal adults. A research group think that there is a causative connection.

WHO reveals high risk TB countries

The estimated rate of tuberculosis (TB) per 100,000 people, compiled from World Health Organisation (WHO) data for each country (2013), shows a rise. There are some interesting geographical findings.
