Long-Term Infectivity of Chikungunya Virus Stored in the Dark at 4°C.

We call into question the established dogma that viruses with envelopes and RNA genomes have limited stability by demonstrating the staggering long-term viability, ∼2 years, of chikungunya virus when stored in liquid environments at +4°C in the dark. We contend that our understanding of the infectivity of a variety of enveloped viruses requires a new approach to identify under standardized conditions the primary determinants of their viability.

First Identification and Genomic Characterization of a Porcine Sapelovirus from Corsica, France, 2017.

We report the isolation and genomic characterization of a strain, or porcine sapelovirus (PSV), from a diarrheic Corsican piglet in France. It shares 87% nucleotide identity with a 2014 German isolate.

Molecular detection of human rhinoviruses in respiratory samples: a comparison of Taqman probe-, SYBR green I- and BOXTO-based real-time PCR assays.

Background: Human Rhinoviruses (HRV) are major causative agents of acute respiratory tract infections in all age group and important contributing factors of childhood morbidity and mortality. Clinical presentation is poorly specific and the great antigenic and genetic variability of HRVs renders the biological diagnosis complex. Here, we have evaluated several molecular diagnostic protocols, including Taqman probe-based and intercalating agent-based RT-PCR assays.
