In PNAS this week: decreased DOCK4 expression in myelodysplastic syndromes plus anemia, hepatitis A evolution, and more.

A survey of small mammals from around the world uncovered new and known hepatoviruses that are helping to clarify relationships between viral clades.

Following a beta evaluation of the system, a virology lab in Sheffield, UK, ran a workflow assessment and found improvements with the system.

The hepatitis C virus test has been approved for both the confirmation of active infection as well as for viral load monitoring.

The tests are the first assays approved by the FDA to run on the firm's Cobas 6800 and Cobas 8800 systems. 

The study demonstrated the efficacy of using the Oxford Nanopore MinIon and a bespoke computational pipeline to perform metagenomics testing of viral infections in patients. 

Researchers found a handful of individuals whose post-transfusion blood samples contained a new virus resembling hepaciviruses and pegiviruses.

The new test will also be packaged as a kit for routine diagnosis of HDV RNA and HBV DNA.

RNA sequencing on samples from three New England seals revealed a new picornavirus that appears to share a common ancestor with human hepatitis A virus.

The funding comes as part of the agency's Advanced Molecular Detection initiative, which is using the technologies to help address infectious disease outbreaks.
