“We expect there are hundreds of thousands of mammalian viruses out there,” says Kevin Olival, a disease ecologist at EcoHealth Alliance, who led the study.

Zika virus’ risk to …: It’s deja vu

Lessons From Rubella Suggest Zika’s Impact Could Linger
March 23, 2016

As researchers try to figure out how much risk Zika virus poses to a fetus, Plotkin says it’s deja vu for folks who lived through that extensive rubella outbreak.

“It enabled the virologists, among them myself, to describe in detail what the virus was doing and to show beyond any doubt that the virus was infecting the fetus and causing the abnormalities,” says Plotkin.

rubella also pushed the federal government to create new programs for special education.

Metagenomics: crAssphage

A highly abundant bacteriophage discovered in the unknown sequences of human faecal metagenomes

Metagenomics, or sequencing of the genetic material from a complete microbial community, is a promising tool to discover novel microbes and viruses.
Viral metagenomes typically contain many unknown sequences.

Here we describe the discovery of a previously unidentified bacteriophage present in the majority of published human faecal metagenomes, which we refer to as crAssphage.
Its ~97 kbp genome is six times more abundant in publicly available metagenomes than all other known phages together; it comprises up to 90% and 22% of all reads in virus-like particle (VLP)-derived metagenomes and total community metagenomes, respectively; and it totals 1.68% of all human faecal metagenomic sequencing reads in the public databases.
The majority of crAssphage-encoded proteins match no known sequences in the database, which is why it was not detected before.
Using a new co-occurrence profiling approach, we predict a Bacteroides host for this phage, consistent with Bacteroides-related protein homologues and a unique carbohydrate-binding domain encoded in the phage genome.
