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

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

Bacteria and viruses can be imaged with helium ions in contrast to electrons, which are the standard workhorse in nanoscale microscopy, an interdisciplinary research consortium from the Nanoscience Center at University of Jyvaskyla in Finland has found. Helium ions, being more massive than electrons, can be focused to a much tighter spot down to the… Read more

Phage therapy may be a safe and effective antibiotic alternative for the treatment of cystic fibrosis lung infections, scientists from the University of Liverpool’s Institute of Infection and Global Health have shown. Chronic lung infections caused by the bacterium Pseudomonas aeruginosa are becoming increasingly difficult to treat due to antimicrobial resistance (AMR). With limited alternative… Read more

What Are Bacteriophages?

Bacteriophages are one of the many types of viruses, which are the most simple living things. When viruses infect animals, plants, or humans, they are called eukaryotic viruses, and they are called bacteriophages when they infect bacteria. All viruses are very tiny microorganisms that can only be observed with a huge magnification by using a… Read more
