Does overcoming a SARS-CoV-2 infection protect against reinfection? The “Rhineland Study”, a population-based study conducted by DZNE in the Bonn area, is now providing new findings in this regard. Blood samples taken last year indicate that an important component of immunity – the levels of specific neutralizing antibodies against the coronavirus - had dropped in most of the study…
Scientists from Würzburg and the US have charted the first global atlas of direct interactions between SARS-CoV-2 RNA and human host cells. This may provide a starting point for novel treatments. SARS-CoV-2 infections pose a global threat to human health and a formidable research challenge. One of the most urgent tasks is to gain a detailed understanding of the molecular interactions between the…
Stringent endoscope cleaning between procedures is vital. However, with so many steps in the process – plus high demand for rapid turnaround of endoscopes – contamination and biofilm build-up are still being reported.

However, an effective disinfection strategy against Coronavirus must consider various factors, says Professor Eike Steinmann, head of the Department of Molecular and Medical Virology at the RUB.
Airborne and potentially deadly, the virus that causes COVID-19 can only be studied safely under high-level biosafety conditions. Scientists handling the infectious virus must wear full-body biohazard suits with pressurized respirators, and work inside laboratories with multiple containment levels and specialized ventilation systems. While necessary to protect laboratory workers, these safety…

Scientists at the University of Bologna have conducted the largest analysis of coronavirus 2019-nCoV genomes sequenced so far. This analysis confirms that the virus originates in bats and shows a low variability: the virus heterogeneity is low. At the same time, researchers identified a hyper-variable genomic hotspot in the proteins of the virus responsible for the existence of two virus…
Modern healthcare without hand hygiene? Inconceivable – particularly in the operating room (OR). But what happens when it is not the surgeon who handles the scalpel, but a robot? Robotic surgery, just like surgery performed by humans, always carries a risk of microbial transmission to the patient, says Professor Johannes K-M Knobloch of University Hospital Hamburg-Eppendorf (UKE). A specialist…
Advances in antiretroviral therapy mean that today, people infected with the human immunodeficiency virus (HIV) can expect a healthy and long life. However, living with HIV does increase the risk of cancer. The reasons for this are multiple and include behavioural risk factors (smoking etc.) but many cancers can be attributed to the effects the virus has on the immune system, specifically its…

Today the environment of each victim is…
Scientists from Imperial College London and the University of Edinburgh have used gene-editing techniques to stop the bird flu virus from spreading, in chicken cells grown in the lab.
Sixty-two percent of Germans fear antibiotic resistance, according to a survey recently conducted by the German Federal Institute for Risk Assessment. ‘Patients colonised by multi-resistant pathogens are particularly scared. But many of these fears are rooted in misunderstandings,’ explained Professor Mathias Pletz at the Congress for Infectious Diseases and Tropical Medicine (KIT).
Viruses are often used as vehicles for delivery in gene therapy because they’re engineered not to damage the cell once they get there, but neglecting to consider how the virus will exit the cell could have consequences. Some viruses use a molecule called heparan sulfate to help them attach to cells. The molecule, found in many different kinds of cells (including those from animal tissue), could…

There are a couple strains of herpes so common that researchers estimate 90% of the human population have them. These strains, human herpes 6 and human herpes 7, usually do not cause severe symptoms when people acquire them. But researchers know that under certain circumstances, dormant herpes viruses in the body can unexpectedly come roaring back and cause complications not typically associated…
Hepatitis B virus (HBV) causes hepatitis B, an infectious disease that afflicts 230 million people worldwide, thereof 440 000 in Germany. Persistence of the virus in liver cells leads to progressive organ damage in the patient and contributes to a high risk of cirrhosis and liver cancer development. Providing a new paradigm to hepatitis B understanding, researchers at the German Cancer Research…

A study published online today in the journal Genome Research offers surprising new clues into the genomic complexity of the giant Mimivirus, the largest known virus in the world. Previous studies have shown that unlike most viruses, the Mimivirus has more genes than many bacteria and performs functions that normally occur only in cellular organisms. The results of the most recent study, led by a…
When we organised the first Diagnostic Week in Karlsruhe, in 1969, no one could have known that this event would one day turn into the annual highlight in the world of medicine, reflected Dr Wolfgang Albath, laboratory medicine pioneer and one of the founding fathers of MEDICA the world`s largest medical trade show. Initially planned as a moving exhibition, the show has been based in…
HIV/AIDS has reached pandemic proportions. 35 million people are infected. Given the situation of hard pressed general practitioners (GPs) today, as well as geographical and other difficulties (as in Africa, for example), a new device that will enable HIV patients to monitor their own health and the effectiveness of treatments, without visiting their doctors so often, is indeed promising.
An international panel of physicians has updated the guidelines and recommendations for antiretroviral treatment of adult human immunodeficiency virus (HIV) infection after evaluating recent data, according to an article in JAMA, a theme issue on HIV/AIDS.
