Why does the flu virus affect some people worse than others?

Influenza affects all people once they become infected. However, the severity of the effects and how long the effects of the virus last for vary between different people. Virologists have been looking into this and now have an answer.

Essential Science: Biosignatures detect early symptoms of TB

Researchers have developed an advanced method for the detection of biosignature, paving the way for the early detection of tuberculosis. The method allows for TB to be detected in patients, months before symptoms appear.

Exploring CBD’s newly found antibacterial properties

Cannabidiol (CBD) may have a new property to add to the others that fall within the medicinal bracket: effectiveness against Gram-positive bacteria, including the ability to act upon some species classed as pathogenic.

Hospital disinfectants struggling to kill C. diff bacteria

One of the key aspects for maintaining healthcare hygiene is the application of cleaning agents followed by disinfectants. This is part of the on-going battle against hospital acquired infections. But just how good are the disinfectants?

How many pathogens are lurking in hospital washing machines?

Microbiologists have found that many washing machines in hospital setting as are reservoirs of multidrug-resistant bacteria. In one case study pathogens, were transmitted regularly to newborns in a neonatal intensive care unit at a children's hospital.

IBM's fingerprint sensor monitors disease progression

Technology firm IBM has designed an interesting item of medical technology, designed to track the progression of disease. This is in the form of a tiny sensor. The main use will be with assessing the effectiveness of different medicines.

Graphene spikes kill pathogenic bacteria

One of the risks with medical implants is infection from bacteria during the surgical process, leading to post-surgical infections. Researchers have demonstrated that coating implants with graphene can help to kill microorganisms

Essential Science: Surfers at risk from pathogenic bacteria

Surfers and others who like aquatic sports have been given a new problem to consider. Research indicates that surfers and body-boarders harbor higher levels of potentially dangerous antibiotic-resistant bacteria in their guts compared with non-surfers.

New study: Snake fungal disease may now be a global threat

A potentially fatal fungus infection found in more than two dozen snake species in Europe and the United States could be lethal to serpents across the globe, a new study finds.

Where will the next major infectious disease outbreak occur?

Copenhage - Macroecologists are altering the health and medical community over a serious lack of data on the worldwide distribution of disease-causing organisms. This paucity of information will happen responses to the next global epidemic.

New technology makes electricity from urine

Bristol - An emerging biotechnology process that allows electricity to be generated from urine is closer to realization, following a new study produced by the University of the West of England.

Essential Science: Year-long survey tracks microbes in hospitals

Understanding the types of microorganisms found in a typical hospital and whether they are pathogens is an important part of good governance. Such investigations need to go further and understand changes over time.

Essential Science: Battling infections with bioelectricity

Is the answer to fighting pathogens connected with bioelectricity? Promising new research suggest this is possible by using drugs to changing electrical charge of cells. Studies have been performed in frogs.

Is tricolsan the answer to surgical site infections?

The use of triclosan-coated sutures could be effective for the prevention of surgical site infections, according to the U.S. Centers for Disease Control and Prevention. This takes the form of a new guideline.

Plant disease patterns offer clues about climate change

General atmospheric models provide an indicator of climate change. More sensitive models are needed to understand what is happening on ground level, however. One way to do this, new research highlights, is by tacking the spread of plant pathogens.

Smartphone adapted to screen for food poisoning

A smartphone has been successfully adapted to screen food samples for the pathogen Escherichia coli 0517. It is hoped the speed and portability of the application will enhance food safety.

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.

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.

Essential Science: Next pathogenic threats identified

Recent years have been a number of pathogenic threats have hit the headlines, with Ebola being the foremost concern in recent years. Looking to the future, scientists have raised concerns about three viruses that the world now needs to prepare for.

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.

A step towards eliminating river blindness parasite

River blindness remains a major concern for parts of the world, especially in Africa and Latin America where up to 37 million people are infected. The disease causes eye and skin diseases. A new study offers a clue for eradication of the disease.

Rapid response team to tackle major disease outbreaks

London - The British government has established a rapid support team, with the intention to respond to urgent requests from countries around the world to help control disease outbreaks.

Disease-causing gut bacteria prevalent in children

A study in Denmark has found an unexpectedly high proportion of a pathogenic gut bacteria present in children. The bacterium is more commonly associated with disease in developing countries.

Using computers to spot global pathogen spread

Edinburgh - The digital age is making inroads into microbiology and epidemiology. Researchers have developed software to help track and to predict pathogenic infections around the world.

Essential Science: New pathogen causes anthrax like disease

A new report has detected a species of Bacillus, genetically distinct to the bacterium that causes anthrax, which causes a similar disease in chimpanzees, gorillas and other animals in Africa.

New model helps to predict future Ebola outbreaks

Scientists have developed a new computer-based model that will help to predict the likelihood of future epidemic and pandemics relating to Ebola and Lassa fever. The model will help to predict disease trajectories.

Oregon company using solar technology to kill pathogens in water

Portland - An Oregon-based start-up company is using solar technology to reduce Salmonella, E. coli and Listeria contamination in agricultural runoff. The company has received a state grant to further develop the passive treatment system called "Ray."

Monkeys contracted bacterial pathogen from humans

Warwick - There are many cases of zoonotic infections, where pathogens are transferred from an animal to a person (Ebola virus is an example.) However, no cases, until now, have been reported the other way around (human to animal.)

Is living in buildings that exclude microbes good for health?

Modern buildings, with advanced air conditioning and filtration, are designed to exclude pollutants and microorganisms from buildings. This may not, according to some scientists, be good for our health.

Seriousness of fungal infections neglected by medical services

There are many pathogens that pose risks to human populations. Despite fungal infections killing more people than malaria, or from certain cancers like breast cancer, the level of research into combating fungal diseases is relatively low in comparison.
