The world is in the midst of a global “superbug” crisis. Antibiotic resistance has been found in numerous common bacterial infections, including tuberculosis, gonorrhoea and salmonellosis, making them difficult – if not impossible – to treat. We’re on the cusp of a “post-antibiotic era”, where there are fewer treatment options for such antibiotic-resistant strains. Given… Read more

Researchers at Karolinska Institutet have developed a new method to separate between two different types of a common herpes virus (HHV-6) that has been linked to multiple sclerosis. “This is a big breakthrough for both the MS and herpes virus research. For one, it supports the theory that HHV-6A could be a contributing factor to… Read more

Viruses are mostly known for their aggressive and infectious nature. It’s true, most viruses have a pathogenic relationship with their hosts – meaning they cause diseases ranging from a mild cold to serious conditions like severe acute respiratory syndrome (SARS). They work by invading the host cell, taking over its cellular machinery and releasing new… Read more

Trillions of bacteria, fungi and viruses live inside us, forming what is known as our microbiota. Far from causing problems, these microbes benefit our health in many ways. Most of our microbiota lives in our gut, yet there is increasing evidence that it can influence how our central nervous system works. Gut microbes produce compounds… Read more

Viruses interact with proteins in the biological fluids of their host which results in a layer of proteins on the viral surface, new research from Stockholm University and Karolinska Institutet shows. This coat of proteins makes the virus more infectious and facilitates the formation of plaques characteristic of neurodegenerative diseases such as Alzheimer’s disease. “Imagine… Read more
