Bacteriophages are viruses that infect bacteria, and in the great war between humans and pathogenic bacteria they can act as allies for both sides.
Widespread antibiotic resistance is no longer a potential problem but has become a major threat, according to the World Health Organization.
Antibiotic resistance is often seen as a modern phenomenon – an ability generated by bacteria in order to defend against the challenges of modern medicine.
If you ever worry that you’re a bit too optimistic about the future, try reading Maryn McKenna’s posts about the growing threat of antibiotic resistance.
Stopping bacteria from maintaining their cell walls could lead to new ways to treat infections
When studying bacteria, human pathogens always get a lot of interest and free press. Pathogens of smaller and less important seeming animals, such as shrimp, tend to generate less press interest.
Ever since the discovery and marketing of penicillin in 1928 by Alexander Fleming, bacteria have been developing resistance to antibiotics at an alarming rate.
A study published last week in the journal Clinical Infectious Disease found that Iowa pig farm workers were six times more likely than non-pig farmers to carry multi-drug resistant Staphylococcus aureus (S.
When confronted with a new bacteria there are a series of simple tests that can be carried out to give a rough idea of the properties of the bacteria you are dealing with.
Just in time for “Get Smart about Antibiotics Week,” I had a refreshing experience recently, working in a different rural hospital. Over that week, I didn’t see one patient with “superbugs” other than the occasional MRSA.
Science at the World Economic Forum is about inspiration, solutions and collaboration. First and foremost, leaders come together in Davos to address global challenges such as antibiotic resistance, climate change and understanding the human mind.
Although bacteria are single celled organisms, they are capable of working together in massive bacterial colonies known as biofilms. Within the biofilm bacteria will differentiate to perform different tasks, all wrapped up within a sticky substance that holds the cells together.
In order to survive, organisms produce small molecules known as ‘primary metabolites’ which help it to grow, develop and reproduce.
All living cells contain DNA; the code for producing every protein needed by the cell. As DNA is important it needs to be kept safe. Plants and animals keep their DNA tightly twisted and organised inside a double-membrane bound nucleus while bacteria keep their DNA coiled up in a big circle, with the occasional loop [...]
A new approach may help curb unnecessary prescriptions
