Apicomplexan-like parasites originated several times independently and many of them contain cryptic plastid organelles, which demonstrate that the parasites evolved from photosynthetic algae.

Each dengue serotype contains moderate antigenic diversity, and population immunity drives clade turnover in a hyperendemic population.

Interferon lambda 4, a protein part of the innate immune response, drives major amino acids selection in patients chronically infected with hepatitis C virus.

Polymorphisms in the IFNL4 gene that affect both the form and the activity of the coded protein are associated with changes in the hepatitis C virus.

Integrated analysis of IFN-λ and HCV amino acid variation indicates the key role of host innate immunity in viral control.

Newly discovered viruses in dead and dying farmed Chinook salmon are widely distributed in threatened wild Chinook and sockeye salmon populations.

Internal DNA pressure of tens of atmospheres inside a herpesvirus capsid powers ejection of the viral genome into a cell nucleus, causing infection.

Single viral mutations can escape polyclonal human immunity to influenza hemagglutinin, but different mutations escape the immunity of different people.

A new cell–cell communication system in Streptococcus salivarius, a human gut commensal, discriminates between close signaling molecules to specifically produce bacteriocin-based antimicrobials and disconnects it from foreign DNA acquisition.

USP49 can increase A3G protein expression and enhance its anti-HIV-1 activity, which is also correlated with hypermutations and affects the HIV-1 latent reservoir.
