Immune defense genes in bacteria and archaea can identify viral proteins, a study finds, revealing similarities between the immune systems of prokaryotic and eukaryotic organisms.
Of the pathogens known to have infected humans, more than half may cause more widespread disease as a result of rising temperatures, precipitation changes, or other climate-related factors, a study finds.
Dozens of researchers, including myself, worked for years to uncover that swine flu had leapt to humans from a pig in Mexico in 2009. We learned a lot about influenza evolution, pig farming, and outbreak risk along the way.
In a first, patients who hadn’t been treated with antifungals were found to carry Candida auris impervious to all three available classes of the drugs.
In Northern California, the proportion of ticks infected with the bacterium Borrelia burgdorferi was the same in shrubland along beaches as in woodland habitats.
When conservationists relocate species, they don’t always account for the pathogens hitching a ride, and the consequences of introducing them to a new environment.
Host vouchering, the practice of preserving species known to harbor infectious diseases, can be used to help determine a pathogen’s source, scientists say.
Half a year after infection, people who had recovered from COVID-19 had robust antibodies, along with traces of the virus in their gut, which may drive long-lasting immunity.
