For the First Time, Researchers Identify the Secret Genetic Weapon of Clostridium difficile

Washington, DC – August 16, 2016 – A trio of researchers at the University of Texas Health Science Center, School of Public Health in Houston, have identified the location of the genes that control production of toxins that harm people infected by Clostridium difficile bacteria. The gene locus, ... Read More

Watch Bacteria Jiggle, Pulse, and Shine to a Party Rock Anthem

A scientist from Columbia University is programming bacteria to "flicker, pulsate, shimmer, flow, and do the wave in a rainbow of neon color". In this video, petri dishes of these glowing bacteria are choreographed to Party Rock Anthem. However, this creative intersection of science and art does... Read More

Microbial Identification and Tracking: the Next Generation

How do you identify an unknown microbe? If you’ve taken an introductory microbiology lab course in the past twenty years, chances are you were assigned an unknown bacterium that you had to identify through differential media and biochemical assays. Newer techniques like qPCR are being standardiz... Read More

Demystifying secondary bacterial pneumonia

In some individuals, an influenza A virus infection can cause asymptomatic Staphylococcus aureus (S. aureus) to travel to the lungs where it can trigger severe, sometimes deadly, secondary pneumonia. S. aureus is one of the most common causes of secondary bacterial pneumonia in cases of seasonal... Read More

Scraping away at the complex microbial communities that cause periodontal disease

Though both gingivitis and periodontitis are diseases of the gums, the related ailments are not simply different severities of the same disease, finds a new study published in Applied and Environmental Microbiology. Researchers confirmed this by investigating the bacterial composition of the sup... Read More

Young Inventors Work On Secret Proteins To Thwart Antibiotic-Resistant Bacteria

Three young inventors and students at Stanford University are working to develop proteins that fight antibiotic resistant bacteria. They are optimistic they have found something that works. The proteins the team is developing attack "something that's essential to bacterial survival". But they wo... Read More

The cities of the future could be built by microbes

Today in Phys.org, Martyn Dade-Robertson explores the possibility of using microbes to produce natural cement. This process, called biomineralisation, was discovered deep under water off the coast of the Greek island of Zakynthos.
Future implications for biomineralisation include self-healing ... Read More
