Study finds biochemical role of crucial TonB protein in bacterial iron transport and pathogenesis

A Kansas State University-led study has discovered the role of a protein in bacteria that cause a wide variety of diseases, including typhoid fever, plague, meningitis and dysentery. The results may lead to new and improved antibiotics for humans and animals.

Phillip E. Klebba, professor and ... Read More

Clever microbes: bacterial sensors and signals

Exploring signalling systems is often a multidisciplinary process, requiring genetic research, mathematical modelling and evolutionary biology. A recent paper looking at the bacterial phage shock response uses all of these approaches to build up a picture of the complete signalling system.

Bacteria Grown in Space Is Thicker and Stronger Than on Earth

When/if humans ever colonize Mars, or any other far off planet in the future, we’ll have to put up with super powered mutant bacteria, according to new NASA research. The data was collected by astronaut crews aboard the Atlantis shuttle, who grew colonies of bacteria—also known as biofilms—for t... Read More

Green Alga Found to Prey on Bacteria, Bolstering Endosymbiotic Theory

A green alga with throat- and stomach-like structures can swallow and digest bacteria when deprived of light, further bolstering Lynn Margulis’s widely accepted idea that the origin of the plant-powering chloroplast was a fortuitous bout of indigestion.

Termed “Endosymbiotic Theory“, the idea... Read More

Bacterial communities swarm into gorgeous works of art

This is a picture of a bacterial community, taken by Eshel Ben-Jacob, who thinks bacteria are both the key to understanding complex biological systems and a source of incredible art. These bacteria, discovered by Ben-Jacob's research team, self-organize into intricate and beautiful systems.

Is That Bacteria Dead Yet? Nano and Laser Technology Packed Into Small Device Tests Antibiotic Treatment in Minutes

Researchers at EPFL have built a matchbox-sized device that can test for the presence of bacteria in a couple of minutes, instead of up to several weeks. A nano-lever vibrates in the presence of bacterial activity, while a laser reads the vibration and translates it into an electrical signal tha... Read More

Creating bacterial synergy

A Winnipeg agricultural biotechnology company that has been selling chemical-free seed inoculants for peas, lentils and soybeans in the U.S. for a couple of years now has regulatory approval to sell in Canada.

Manas Banerjee, the CEO and founder of XiteBio Technologies Inc. is excited about t... Read More

High-Octane Biofuels In The Near-Future? New Lines Of Engineered Bacteria Bring The Goal Closer

High-octane biofuels — produced with the aid of newly created lines of engineered bacteria — may be in the near future thanks to new research from the Wyss Institute for Biologically Inspired Engineering at Harvard University and the Department of Systems Biology at Harvard Medical School.

Stop Action Videos, Animation, and Bdellovibrio

My wife, who is a mathematician and artist, made a stop motion video using Play-Doh that represents the life cycle of the bacterial predator, Bdellovibrio. This brings together interesting microbes, animation, and thoughts about what students might do to understand processes in microbiology! Read More

This Image Could Lead to Better Antibiotics

This may look like a tangle of squiggly lines, but you’re actually looking at a molecular machine called a ribosome. Its job is to translate DNA sequences into proteins, the workhorse compounds that sustain you and all living things.

The image is also a milestone. It’s the first time the atom... Read More

Survey Shows Increase in Resistance to Drug Therapies Among Bovine Respiratory Disease Cases

A survey of records of bovine respiratory disease cases at the Kansas State Veterinary Diagnostic Laboratory showed that drug resistance in one of the primary pathogens that cause BRD, Mannheimia haemolytica, increased over a three-year period.

“We have been seeing an increase in the number o... Read More

Scientists view ‘protein origami’ to help understand, prevent certain diseases

Scientists using sophisticated imaging techniques have observed a molecular protein folding process that may help medical researchers understand and treat diseases such as Alzheimer’s, Lou Gehrig’s and cancer.

The study, reported this month in the journal Cell, verifies a process that scienti... Read More

Climate Change May Radically Transform Desert Bacteria

Climate change may transform the community of microbes that forms the crucial top layer of soil, known as a biocrust, in deserts throughout the United States, new research suggests.

The study, published today (June 27) in the journal Science, found that one type of bacteria dominates in warm ... Read More

Antimicrobial affect of acidophil actimyces isolated from Azerbaijan's soil against E.coli

This picture proves antagonistic property of acidophil actinomyces against Escherichia coli. These cultures of actinomyces were isolated from Azerbaijan's soil in 2012 by me. Read More

Salmonella Infection Is a Battle Between Good and Bad Bacteria in the Gut

The blockbuster battles between good and evil are not just on the big screen this summer. A new study that examined food poisoning infection as-it-happens in mice revealed harmful bacteria, such as a common type of Salmonella, takes over beneficial bacteria within the gut amid previously unseen ...

Study ranks social contacts by job and social group in bid to fight infectious diseases

In the light of Novel Corona Virus, concerns over H7N9 Influenza in S.E. Asia, and more familiar infections such as measles and seasonal influenza, it is as important as ever to be able to predict and understand how infections transmit through the UK population.

Researchers at the University ... Read More

Influenza infection increases likelihood of bacterial pneumonia 100-fold, U-Michigan-led study finds

It's been known for more than two centuries that pneumonia cases increase during flu epidemics.

But population-level epidemiological studies looking at seasonal patterns of influenza and pneumococcal pneumonia incidence have revealed either a modest association or have failed to identify any ... Read More

Cell Biologist to Begin Work on Discovering Structure of Malaria Parasite Genome

Malaria is one of the most important infectious diseases in the developing world, with the absence of a vaccine and the development of parasite resistance to commonly used antimalarial drugs complicating efforts to fight the deadly disease.

The parasite that causes malaria is Plasmodium, whic... Read More
