Lyme disease: The pathogen’s cunning strategies for persistent infection offer clues for vaccine development

The bacterium that causes Lyme disease is a master of disguise, changing its appearance to evade the immune system as it moves from the ticks that carry it to humans or animals.

How does fever help fight infections? There’s more to it than even some scientists realize

The heat and chills that come with fever are not only uncomfortable but also metabolically costly. Increased body temperature, however, can make all the difference when you’re sick.

Leprosy-causing bacteria found in armadillo specimens highlight value of museum collections for tracking pathogens

Museum archives hold biological specimens that have been collected over years or even decades. Modern molecular analysis of these collections can reveal information about pathogens and their spread.

Disease-causing parasites can hitch a ride on plastics and potentially spread through the sea, new research suggests

Normally land-bound pathogens that cause deadly diseases for both humans and animals can cling to microplastics and end up in your seafood.

Charting changes in a pathogen’s genome yields clues about its past and hints about its future

After a nose swab tests positive for a virus or bacteria, scientists can use the sample’s genetic sequence to figure out where and when the pathogen emerged and how fast it’s changing.
