Antibiotic resistance could make diphtheria ‘major global threat’ again

Diphtheria – a relatively easily-preventable infection – is evolving to become resistant to a number of classes of antibiotics and in future could lead to vaccine escape, warn an international team of researchers from the UK and India. The researchers, led by scientists at the University of Cambridge, say that the impact of Covid-19 on diphtheria vaccination schedules, coupled with a rise in…

Post-transplant HCMV infection: pre-emptive strike could save many lives

A potential new treatment to protect immunosuppressed patients from human cytomegalovirus (HCMV) has been discovered by scientists at the University of Cambridge. Their study shows that certain epigenetic inhibitors expose and help to destroy dormant HCMV infections, which often reactivate to cause serious illness and death in these vulnerable groups. Subject to clinical trials, their proposed…

A 'fake handshake' to trick the coronavirus

Scientists have developed peptides that fit snugly into a groove on the SARS-CoV-2 Spike protein that it would normally use to access a host cell. These protein fragments effectively trick the virus into “shaking hands” with a replica rather than with the actual protein on a cell’s surface that lets the virus in. revious research has determined that the novel coronavirus binds to a receptor…

Better detection and diagnosis of fungal infections

Beta-glucan tests are proving to be pivotal in the better detection and diagnosis of fungal infections. As a robust complimentary test for traditional testing techniques and biomarkers, it is helping clinicians deliver rapid results and offering greater reassurance in more accurately identifying such infections. β-glucan testing, which is an in vitro diagnostic test, is regularly used at…

CRP apheresis: First successful treatment of Covid-19 patient

Apheresis, a procedure that separates and removes particular blood constituents, shows promise for Covid-19 cases: the first patient successfully underwent so-called CRP apheresis, which can prevent potentially fatal consequences of the infection.

Experts: Impact of Covid-19 in Africa “vastly underestimated”

The impact of Covid-19 in Africa has been vastly underestimated, warn researchers in a new study. Outside of South Africa, this is the first study to provide systematic surveillance data capturing the impact of Covid-19 in Africa. Their findings are based on polymerase chain reaction (PCR) test results for 364 deceased people of all ages at the University Teaching Hospital morgue in Lusaka,…

'Cells of the future' might cure lung infections

Healing the body with cells – this is the ambitious goal of scientists at Hannover Medical School (MHH). With this in mind, Professor Dr. Nico Lachmann and Dr. Robert Zweigerdt have initiated a research collaboration and license agreement with the pharmaceutical company Novo Nordisk A/S, to combine academic knowhow with the translational power of the industry. The overall aim of the endeavor is…

A 'blueprint' for preventing the next pandemic

Scientific and public health experts have been raising the alarm for decades, imploring public officials to prepare for the inevitability of a viral pandemic. Infectious epidemics seemingly as benign as "the flu" and as deadly as the Ebola virus provided ample warning, yet government officials seemed caught off guard and ill prepared for dealing with Covid-19.

Using VR to win over vaccine skeptics

People who are sceptical of getting vaccinated against infectious diseases may soon get a whole new perspective on things. Professor Robert Böhm and Associate Professor Guido Makransky from the Center for Social Data Science (SODAS) and the Department of Psychology at the University of Copenhagen have received DKK three million in funding from EIT Health for developing a virtual reality app to…

Covid-19 a far more serious threat than seasonal influenza, confirms huge data set

Nearly twice as many people were admitted to hospital for Covid-19 at the height of the pandemic than were for influenza at the peak of the 2018/2019 flu season, a study of French national data published in The Lancet Respiratory Medicine journal has found (Covid-19, 89,530 patients vs influenza, 45,819 patients).

Where could the next pandemic emerge?

An international team of researchers has taken a holistic approach to reveal for the first time where wildlife-human interfaces intersect with areas of poor human health outcomes and highly globalised cities, which could give rise to the next pandemic unless preventative measures are taken.

Cell membranes in super resolution

For the first time ever, expansion microscopy allows the imaging of even the finest details of cell membranes. This offers new insights into bacterial and viral infection processes.

Device rapidly detects antibiotic-resistant bacteria

Bacterial infections have become one of the biggest health problems worldwide, and a recent study shows that COVID-19 patients have a much greater chance of acquiring secondary bacterial infections, which significantly increases the mortality rate.

Digital epidemiology in the Covid-19 war

Digital epidemiology is on the frontline in the Covid-19 war, with innovative techniques used to observe and monitor this viral spread across populations. Its increasingly important role was outlined to a virtual session at Medica 2020 by theoretical biologist Professor Dirk Brockmann. In a keynote presentation ‘Perspective of digital epidemiology – opportunities, promises and challenges’,…

Prior COVID-19 infection offers protection from re-infection

A new study suggests that individuals who have previously had COVID-19 are highly unlikely to contract the illness again, for at least six months following their first infection. The study, done as part of a major collaboration between the University of Oxford and Oxford University Hospitals (OUH) NHS Foundation Trust, was published as a pre-print.

Coronavirus re-infection: what we know so far – and the vital missing clues

As President Trump claims that he is immune to COVID-19 and isolated reports emerge of reinfection, what is the truth about immunity to COVID-19? To date, there have been six published cases of COVID-19 reinfection, with various other unverified accounts from around the world. Although this is a comparably small fraction of the millions of people known to have been infected, should we be…

The antiviral effect of innate immunity

Innate immunity is the fastest-acting component of the immune system, but so far little is known about its role during infection with SARS-CoV-2. A few hours after an infection, the body emits an alarm signal, interferon, enabling cells that have not yet been infected to produce antiviral proteins. This phenomenon occurs well before the production of neutralizing antibodies. Scientists from the…

It is only 120 millionths of a millimetre in size but can bring entire countries to a standstill: the Corona virus. Even if it were to disappear one day, viral infections will still be among the most frequent and difficult-to-treat diseases in humans. Even decades of research have only produced a few standardized vaccines and strategies for treatment to combat just a small number of viruses. Nor…
