From Jing Wang et al. at Sun Yat-sen University, this is a new Nature Communications publication describing the virome of 149 bats collected in Yunan Provinde from 2015-2019. A metagenomic assembly produced contigs from 55 different mammal-associated viral species, including 5 similar to known human or livestock pathogens, including 2 Sarbecoviruses, with evidence of recombination.

Individual bat virome analysis reveals co-infection and spillover among bats and virus zoonotic potential - Nature Communications
Viral diversity and abundance in bats are incompletely understood. Here, analyzing individual bat viromes, the authors observe a high frequency of co-infection and spillover among the animals and identify viruses with the potential to infect humans o…Nature
The Human Virome Project is coming y’all!
Notices of Intent to Publish went out yesterday to announce 4 upcoming NIH funding opportunities:
1. Consortium Organization and Data Collaborating Center
2. Longitudinal characterization of the virome in cohorts
3. Tools for interrogation and annotation of the virome
4. Functional interactions between viruses, human, and microbial hosts

How RNA viruses can use their dsRNA intermediate state as a de facto latent state, facilitating viral persistence.
Positive single-stranded #RNA viruses have a replication cycle that includes a double-stranded RNA (dsRNA) intermediate state.

A global virome of methanogenic archaea highlights novel diversity and adaptations to the gut environment
Mobile genetic elements (MGEs), especially viruses, have a major impact on microbial communities. Methanogenic archaea play key environmental and economical roles, being the main producers of methane -a potent greenhouse gas and an energy source.www.researchsquare.com
Suggested factors leading to collapse of bee colonies worldwide include pesticides, bacteria, & parasitic mites.
But the picture would not be complete unless we looked into the possible role of viral infections, too.
And so, welcome to the bee #virome :

Nationwide genomic surveillance reveals the prevalence and evolution of honeybee viruses in China - Microbiome
Background The economic and environmental value of honeybees has been severely challenged in recent years by the collapse of their colonies worldwide, often caused by outbreaks of infectious diseases.BioMed Central
😲 Two recent studies from China look at the truly wide diversity of RNA viruses found in ticks.
"Extensive diversity of RNA viruses in ticks revealed by metagenomics in northeastern China"
https://doi.org/10.1371/journal.pntd.0011017
"Metavirome of 31 tick species provides a compendium of 1,801 RNA virus genomes"
https://www.nature.com/articles/s41564-022-01275-w
A lot of insights in these two studies, so I'll just point out a few things that I personally found interesting.

Extensive diversity of RNA viruses in ticks revealed by metagenomics in northeastern China
Author summary Ticks are important vectors to transmit many infectious agents. In recent years, many novel tick-borne viruses associated with human illness, including Alongshan virus, Songling virus, and Beiji nairovirus, have been identified in nort…doi.org
