Biofilms of major pathogenic bacteria can deform soft surfaces

The vast majority of bacteria in the world live on surfaces by forming structures called "biofilms". These communities host thousands to millions of bacteria of different types, and are so biologically complex and active that scientists describe them as "cities".

New nanoparticle formulation could stop tooth decay without killing oral bacteria

Oral bacteria are ready to spring into action the moment a dental hygienist finishes scraping plaque off a patient's teeth.

Synthetic peptide makes multidrug-resistant bacteria sensitive to antibiotics

Scientists at Nanyang Technological University, Singapore (NTU Singapore) have developed a synthetic peptide that can make multidrug-resistant bacteria sensitive to antibiotics again when used together with traditional antibiotics, offering hope for the prospect of a combination treatment strategy to tackle certain antibiotic-tolerant infections.

Research into metal-breathing bacteria could pave way for new generation of 'living sensors'

When the Shewanella oneidensis bacterium "breathes" in certain metal and sulfur compounds anaerobically, the way an aerobic organism would process oxygen, it produces materials that could be used to enhance electronics, electrochemical energy storage, and drug-delivery devices.

Evaluating the impact of sugary and acidic drinks on tooth enamel

Using atomic force microscopy, researchers have quantitatively assessed the effect of sugary and acidic drinks on human tooth enamel at the nanoscale level.

Salmonella biofilm protein can cause autoimmunity and arthritis in animals

Scientists from the Vaccine and Infectious Disease Organization-International Vaccine Centre at the University of Saskatchewan and Temple University have demonstrated that a Salmonella biofilm protein can cause autoimmune responses and arthritis in animals.

Jena microbiologists discover natural products in new species of bacteria

The sheer endless expanses of the oceans are hostile deserts -- at least from the perspective of a bacterium living in water.

New Functions Of A Protein May Improve Biocontrol Methods In Sustainable Agriculture

The laboratory of the UMA has proved that Bacillus subtilis cells, when deprived of an amyloid protein (TasA), exhibit a range of cytological anomalies.

Study shows the dual role of amyloid proteins in Bacillus physiology

When Bacillus subtilis cells are deprived of an amyloid protein, they show a range of cytological dysfunctions and anomalies that cause their premature death.

New technique reveals the proliferation and genetic exchange of bacteria

Researchers have made a breakthrough interpretation of the way bacteria move and carry out genetic exchange—that may possibly result in the development of novel antimicrobial drugs.

Research provides new insights into building blocks of gum disease

Porphyromonas gingivalis is a major bacterial pathogen which leads to periodontitis also known as gum disease. In Japan, 80% of adults aged 35 and over suffer from this disease. What's more, P. gingivalis has also been linked to rheumatoid arthritis, cardiovascular disease, pancreatic cancer, and even Alzheimer's disease.
