Redondoviruses, which have been associated with cases of periodontitis and other diseases, turn out to live inside the amoeba Entamoeba gingivalis.

The parasite appears to make infected wolves less risk-averse, potentially influencing the behavior of packs.

Researchers report what appears to be the second case of a person’s immune system clearing the virus on its own.

Using a novel lab technique, researchers identified a mutation that allows the virus to insert more genetic material into host cells.

Whether the galls that aphids make on witch hazel leaves are red or green is associated with a gene expressed in the insects’ salivary glands.

In a trio of studies, researchers follow up on a 40-year-old finding that certain bacteriophages replace adenine with so-called diaminopurine, perhaps to avoid host degradation.

Host vouchering, the practice of preserving species known to harbor infectious diseases, can be used to help determine a pathogen’s source, scientists say.

Rather than introducing small chunks of DNA as other viruses do, some giant viruses can contribute more than 1 million base pairs to a host’s genome, broadening the ways in which viruses may shape eukaryote evolution.

The host transcriptional signature elicited by the coronavirus appears to be less robust and lacks the induction of key antiviral genes.

Aphids induce their host plants to produce tiny hairs that help keep the surfaces water-repellent.

Cryo-electron tomography reveals how Salmonella sets up physical interactions with host cells.

The bat version of the STING protein helps dampen the mammals' immune response to infection, researchers have found.

With the help of a virus that infects its prey’s nervous system, a parasitoid wasp coerces a lady beetle to protect its young.

A single amino acid change helps a plant pathogen related to the causative agent of the Irish potato famine infect a new host.

Examples of parasites that manipulate the behavior of their hosts are not hard to come by, but scientists have only recently begun to understand how they induce such dramatic changes.

Findings suggest winged mammals could spread SARS-like viruses across Asia, Australia and Europe
