Hidden diversity and expanded host range of sarthroviruses, including terrestrial vertebrates

The paper identifies ten new sarthrovirus species from diverse hosts in Australia, expanding the family to 11 species and seven genera, and suggests alternative replication strategies and helper virus associations.

MaRNAV-1, an intracellular virus of Plasmodium vivax, is associated with increased parasite transmission and altered host immune response

This study identifies MaRNAV-1 as an intracellular virus in Plasmodium vivax that increases transmission and alters host immune responses.

Mapping the global distribution and spread of the Plasmodium vivax-associated virus MaRNAV-1

The paper maps the geographic distribution and host associations of MaRNAV-1, a virus linked to Plasmodium vivax, using metatranscriptomic data.

Metagenomic resolution of spotted-fever group Rickettsia tasmanensis and novel DNA viruses in Australian wildlife ticks, with spatial modelling of Rickettsia exposure zones.

The paper identifies a novel Rickettsia species and DNA viruses in Australian ticks using metagenomics and models Rickettsia exposure zones.

Tunicate metatranscriptomes reveal ancient virus-host co-divergence and inter-order recombination in the evolutionary history of disease-causing viruses

The paper analyzes tunicate metatranscriptomes to show that some disease-causing RNA viruses evolved before vertebrates and that recombination between viral orders shaped their evolution.

A virus associated with the zoonotic pathogen Plasmodium knowlesi causing human malaria is a member of a diverse and unclassified viral taxon

The paper identifies a novel RNA virus in zoonotic Plasmodium knowlesi isolates, showing it belongs to an unclassified viral taxon called ormycoviruses.
