Connection between gut microorganisms and Parkinson’s disease

A new connection between the microbiome of the gut and human health and disease has been made. Here Parkinson's disease, along with the medications to treat Parkinson's, alter the composition of the trillions of bacteria that make up the gut microbiome.

Screening bacteria for valuable biosynthetics

The microbial world contains the potential to produce a range of useful materials. To speed up screening of potential microbes a new ‘big data’ computer program has been constructed. This allows researchers to shift through microbial genomes rapidly.

Oldest ever microbial fossils discovered

Remains of microorganisms, said to be over 3,770 million years old, have been discovered. These remnants provide conclusive evidence of the age of one of the oldest life forms on Earth.

New drive to eliminate trachoma blindness

The campaign to eliminate the bacterial blindness disease trachoma has received a boost with a $11.7 million donate from the Conrad N. Hilton Foundation. The funding, for research, will be handled by The Carter Center among other bodies.

Dirty dozen: The 12 most dangerous bacteria

The World Health Organization (WHO) has named the top dozen of bacteria that pose the greatest risk to humanity. The United Nations health agency also warns that medics are running out of options to treat the diseases.

Hospital infections impact negatively on spinal cord patients

A new study heqaded by The Ohio State University Wexner Medical Center has identified hospital-acquired pneumonia and wound infections negatively affect the clinical long-term outcome after acute traumatic spinal cord injury.

Which U.S. states are the worst for STDs?

In time for Valentine's Day, new information collated reveals the U.S. states with the highest levels of sexually transmitted diseases, using some common pathogens as measures.

Bacteria fed synthetic iron become electrical generators

Some bacteria are electrogenic, meaning they can generate current as part of their metabolism. Researchers have succeeded in conferring this ability onto bacteria that do not naturally have this function. The aim is sustainable electricity generation.

Efficient microbial fuel cell made from paper

Fuel cells are one of the renewable sources of energy being actively worked on by scientists. The basis of many fuel cells are specific bacteria, and a new breakthrough has been made using a paper-based system.

Food poisoning bacteria exerts mind control over mice

A common food bacterium has been found to alter the brains of mice, exerting a form of mind control over the rodents. The observations could actually lead to a medical innovation to assist cancer patients.

Many household dogs are carrying MRSA

Community transferred and acquired MRSA is a growing concern, especially for those admitted to hospital. One common reservoir for the antibiotic-resistant bacteria are domestic dogs. A new study reveals the extent of the problem.

Bacteria can form potentially deadly prions

Bacteria have been shown to form prions. These are clumps of misfolded protein which have the potential to cause nerve damage in mammals. Some prions have been shown to cause fatal neurodegenerative conditions.

Project underway to map hospital infection zones

Chicago - To better understand the infection risks to patients a plan has been drawn up to map the microbiome of hospitals. This is on the premise that each hospital carries its own, unique microbial signature.

Bacteria powered battery built on sheet of paper

New York - In the quest to find new and efficient means of generating power a research group have developed a battery, resembling a thin sheet of paper, which is powered by microorganisms.

Essential Science: Using bacteria to generate useful chemicals

Bacterial cells have been engineered to produce quantities of a chemical called serine. This chemical has a useful function – it is used to manufacture detergents and its acts as a building block for many industrially important chemicals.

New antibiotic for gonorrhea developed

York - The therapeutic effects of carbon monoxide-releasing molecules have been used to develop a new antibiotic to combat the sexually transmitted infection gonorrhea.

Lyme disease ticks detected in U.S. Eastern National Parks

Lyme disease is continuing to spread, via ticks, across the U.S. A sign of further potential disease transfer, a new study has discovered the ticks carrying the disease in eastern national parks.

Laser tractor beam used to trap bacteria

Frankfurt - Viewing the activities of the microbial world is key for the study of disease and for drug development. German researchers have developed a new method for capturing and trapping bacteria using lasers.

Fighting pathogens now involves waking them up

Many pathogenic bacteria are hard to kill because they are resistant to antibiotics. Other bacteria are resistant because they enter into a state of dormancy. Waking microbes up is key to killing them, researchers argue.

Microbiomes interact with mental health treatment

People who experience a 'nervous stomach' under periods of stress will understand the connection between the gut and a person’s mood. It seems that there is now scientific evidence to support this link.

Bacteria in undercooked chicken causes Guillain-Barré syndrome

A new study suggests that a common food pathogen associated with undercooked chicken, can cause Guillain-Barre syndrome.

Predatory bacteria used to release bioplastics

Researchers have come up with a novel method of extracting bioplastics from bacteria. This involves the use of another, predatory bacterium to extract the biologically created plastics from the producing bacteria.

Essential Science: Why nitrogen is a key driver for gut health

Researchers have moved closer to connecting diets and dieting strategies and a healthy gut. This fits together with the need for having the right balance of microorganisms, and here nitrogen plays a key role.

Trouble with contact lenses? Might be your microbiome

Some people cope well with contact lenses, other suffer with itchy eyes or run into problems. The reason may be due to the microbial composition of the eye, according to a new study.

Antimicrobial resistant bacteria detected in air pollution

Areas subject to air pollution contain a growing concentration of bacteria that are resistant to antimicrobials, according to a new study. Consequently, air movement may provide a new ways for their transmission.

Battle with super-bugs moves onto tackle E. coli

London - With success achieved in reducing incidences of MRSA, the British government has moved its focus towards reducing the number of cases of the bacterium Escherichia coli in hospitals.

Rapid method for diagnosing sepsis

Although there are tell-tale signs for sepsis (such as a rise in body temperature and faster breathing), a fast diagnoses is essential. Traditional methods use blood culture, which takes time. To overcome this, a rapid method has been developed.

Mouth bacteria linked to migraines

Migraines are triggered by many different factors, from lack of sleep, stress and by certain foods. A new study indicates that the microorganisms resident in the mouth may also play a part.

New drug target designed to attack gut bacteria

Gastroenteritis is caused by some foodborne bacteria. Researchers have designed a new antimicrobial drug to take on one of the world’s most prevalent foodborne bacteria.

Milk from Tasmanian devils helps fight superbugs

It seems one of the strange science stories of the week, but Australian scientists have discovered that the milk from Tasmanian Devils has antimicrobial properties, including activity against antibiotic resistant organisms.
