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 ...

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 ...

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 ...

In a recent study posted to the bioRxiv* preprint server, researchers develop an automated and heuristic approach-based method that uses shared ancestral genotype information to define pathogen ...

Combining genomic data and human travel patterns over a 14-year period in South Africa reveals key insights into the spread, evolution and resistance patterns of a major bacterium behind pneumonia and ...

Researchers at North Carolina State University have developed a new online tool—reportedly the first of its kind for plant pathogens—to help researchers across the globe identify, detect, and monitor ...

Plant–pathogens and insect pests, hereafter pests, play an important role in structuring ecological communities, yet both native and introduced pests impose significant pressure on wild and managed ...

A new technique known as phylowave showed potential to identify differences in fitness among viral and bacterial pathogens, based on data from a study including SARS-CoV-2, influenza A subtype H3N2, ...

The study was conducted in a grassland on the UC Santa Cruz campus known as the “Great Meadow.” (Photo by Gregory Gilbert) Researchers grew a selection of 44 wild plant species with no previous ...

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 ...
