Superinfection with multiple strains or subtypes of the human and simian immunodeficiency viruses has been documented. Recent increases in the prevalences of both unprotected anal intercourse and ...

In a recent study posted to bioRxiv* preprint server, researchers found frequent recombination of severe acute respiratory syndrome (SARS)-like coronaviruses (SL-CoVs) with diverse gene pools. Study: ...

Sclerotinia sclerotiorum is a globally significant fungal pathogen that affects a wide range of economically important crops. Its population structure is complex, owing to a combination of clonal ...

Bufavirus and protoparvoviruses have emerged as significant pathogens affecting both humans and animals. These nonenveloped, single-stranded DNA viruses belong to the Parvoviridae family and have been ...

Like all living things, the virus that causes COVID-19 continues to evolve, illustrating why we need to understand the forces of evolution. The SARS-CoV-2 virus likely “jumped” from a related mammal ...

In a recent study posted to the medRxiv* preprint server, researchers analyzed monkeypox (MPX) virus (MPXV) sequences during the current 2022 outbreak to investigate whether MPXV is adapting for ...

New studies underscore how coronaviruses frequently mix their genetic components — which could contribute to the rise of dangerous variants. By Roxanne Khamsi In recent weeks, scientists have sounded ...

Herpes simplex virus (HSV) types 1 and 2 are globally prevalent viruses that establish chronic infections and cause painful ulcers during reactivation periods. Although HSV-1 primarily causes ...

Two mutant strains of the novel coronavirus may have combined their genomes to create a new and heavily mutated variant of the deadly SARS-CoV-2 virus, which is responsible for causing COVID-19. As ...

Researchers calculated the likelihood of different viruses recombining in the same animal to make new disease-causing pathogens. By James Gorman As the coronavirus continues to evolve, the scientific ...

In a landmark feat of genetic engineering, researchers at the MRC Laboratory of Molecular Biology (LMB) in Cambridge have created a strain of Escherichia coli that functions with just 57 codons, down ...
