The evolution of pathogens has received attention in a wide range of scientific fields, such as epidemiology, demography, and evolutionary ecology. Understanding pathogen evolution is particularly ...

Pathogen adaptation occurs when novel variants gain greater fitness in the current environment than their predecessors. Host immunity, whether vaccination- or infection-induced, could shape the ...

A new way to map the spread and evolution of pathogens, and their responses to vaccines and antibiotics, will provide key insights to help predict and prevent future outbreaks. The approach combines a ...

A parasite which has devastating impacts on agriculture and human health is the first pathogen to have its proteins located and mapped within its cells -- providing clues to their function and helping ...

Heterogeneity is ubiquitous in real-world host populations, yet most theories assume homogeneity. Using a metapopulation model, we examine how host heterogeneities, such as uneven movement patterns ...

Pathogen evolution is a central theme in disease ecology, as genetic diversity and fitness changes in pathogens have a ...

Humans have been getting infected by ancient bacteria and viruses for at least 37,000 years. Now, for the first time, pathogen DNA has uncovered a pivotal disease "turning point" that happened 6,500 ...

Sébastien Calvignac-Spencer searches museum jars for genetic traces of flu, measles and other viruses. Their evolutionary stories can help treat modern outbreaks and prepare for future ones. Like many ...
