Researchers identify antibodies that hold promise as Ebola treatments
The fight to contain the 2013-16 Ebola outbreak in West Africa was hampered by the lack of an effective treatment or vaccine. Researchers funded in part by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), have studied the blood of an Ebola survivor, searching for human antibodies that might effectively treat not only people infected with Ebola virus, but those infected with related viruses as well.

Guidelines for disposal of liquid waste from Ebola patients could put sewer workers at risk
Research from Drexel University and the University of Pittsburgh suggests that guidelines for safe disposal of liquid waste from patients being treated for the Ebola virus might not go far enough to protect water treatment workers from being exposed. In a study recently published in the journal Water Environment Research, a group of environmental engineering researchers reports that sewer workers downstream of hospitals and treatment centers could contract Ebola via inhalation -- a risk that is not currently accounted for in the Centers for Disease Control and Prevention or World Health Organization Ebola response protocol.

A fungus that compromises the immune system of mosquitoes, making them more susceptible to infection with the parasite that causes malaria, has been discovered by scientists. Because environmental microorganisms can vary greatly from region to region, the researchers say the findings may help explain variations in the prevalence of malaria in different geographic areas.

Genetic mutation may increase susceptibility to cytomegalovirus infection
Experimenting with human cells and mice, Johns Hopkins researchers have found that a genetic mutation that alters a protein called NOD1 may increase susceptibility to human cytomegalovirus (CMV) infection. CMV is a common pathogen that infects almost 60 percent of adults in the U.S., according to the Centers for Disease Control and Prevention (CDC), and can lead to devastating developmental defects in fetuses and severe disease in people with weakened immune systems.

Long-term chronic bone loss occurs even after one time malaria infection
Malaria caused by Plasmodium parasites is a life-threatening infectious disease that kills at least half a million people annually while causing over 200 million new infections. In some cases, complications can quickly develop such as cerebral malaria, respiratory distress and severe anemia, often leading to death. The majority of patients recover from disease, however, there is increasing evidence to suggest that survivors experience long-term 'hidden' pathologies due to infection that are as yet poorly defined.

Looking for life's (lower) limits
Just how little energy life needs to survive is the subject of a new study. by analyzing maintenance budgets and cellular processes across species and sizes of bacteria, researchers found distinct trends along the spectrum and one surprising constant. Their investigation into the lower bound of energy required for life helps us understand ecological constraints on other planetary bodies in our solar system as well as our own.

Magnetic purification of blood 'pulls out' the bacteria
Blood poisoning is still fatal in more than 50% of cases, but can be cured if treated at an early stage. the highest priority is therefore to act quickly. for this reason, doctors usually administer antibiotics even in the event of a suspicion of blood poisoning, without first ascertaining whether it is actually a bacterial sepsis, which in turn greatly increases the risk of resistance to antibiotics developing.

Microscopic Peptide Polymers Kill Drug Resistant Bacteria Without Any Drugs
Drug resistant bacteria is showing its face around the world and causing worry that the golden age of antibiotics is coming to a close. at the University of Melbourne in Australia researchers have been working on something called structurally nanoengineered antimicrobial peptide polymers (SNAPPs), tiny microscopic devices that are able to damage bacterial walls without using any drugs. Shaped like tiny stars, it is their shape that seems to be the mechanism that helps destroy cell walls and let ions move across the membrane without any regulation, eventually leading to cell death.

Their findings could eventually lead to minuscule robots that seek out and treat lesions in the human body.

Novel approach to seeing dengue infection in the body
Positron emission tomography (PET) paired with the glucose metabolism probe, fluorodeoxyglucose (FDG), is considered 'old' technology in the field of cancer. A team found a new use for this 'old' technology in infectious diseases research. Using FDG-PET to image dengue infection in mice, the team has potentially uncovered a novel way to track the infection in real-time and more accurately assess the effectiveness of new dengue treatments.

A research team has identified bacterial infection as a possible cause of Overactive Bladder Syndrome (OAB). OAB is a condition where the bladder muscle spontaneously contracts before the bladder is full. In the USA, it is ranked in the top 10 of common chronic conditions, competing with both Diabetes and depression, with a reported prevalence of up to 31-42% in the adult population.

Sabotaging bacteria propellers to stop infections
When looking at bacteria, you typically see also flagella: long hairs that protrudes from the bacteria's body. the key function of the flagella is movement -- what scientists call 'motility'. the flagella give the bacteria the ability to swim in their environment by rotating like propellers. Bacteria can have a different number of flagella, and flagella are important because there is a clear correlation between motility and infection.

Study shows how phage-resistant cells become susceptible upon co-incubation with sensitive bacteria
Bacteriophages (phages) are probably the most abundant entities in nature, often exceeding bacterial densities by an order of magnitude. as viral predators of bacteria, phages have a major impact on bacterial communities by reducing some bacteria and enabling others to flourish. Phages also occasionally package host DNA and deliver it to other bacteria, in a process known as horizontal gene transfer (HGT).

Number of tuberculosis cases in India is double current estimates, says new study
The number of cases of tuberculosis (TB) in India may be up to two to three times higher than current estimates, suggests a new study. TB is a bacterial infection, spread through inhaling tiny droplets from the coughs or sneezes of an infected person. India has the highest number of TB cases in the world, and accounts for at least a quarter of all cases worldwide.

Researchers discover underlying cause for formation of granulomas
Granulomas are tissue nodules of immune cells that occur in diseases such as tuberculosis and sarcoidosis and can damage many organs. for the first time, a team of researchers at MedUni Vienna has identified what causes them to form. It is the chronic activation of the metabolic sensor mTOR (mammalian Target of Rapamycin) that is responsible for the formation of granulomas.

Strengthening immune defence system may provide treatment alternative for tuberculosis
Eight million people suffer from - and two million die from - tuberculosis every year. for HIV patients, tuberculosis is the leading cause of death. Antibiotics are currently used against tuberculosis, as no effective vaccine could be developed thus far - but with growing resistance to antibiotics, the cure for tuberculosis is threatened.

TB bacterium may suppress immune system to spread disease
Scientists have a good understanding of how the bacterium that causes tuberculosis, one of world's leading causes of death, evades the immune system to establish a foothold in the body. However, what has not been clear is the role of the pathogen in undermining the immune system to promote spread of the disease. Now, a new study uncovers evidence that the disease bacterium disrupts regulatory pathways in white blood cells that limit tissue destruction.
