Prediction of SARS-CoV-2 Variant Lineages Using the S1-Encoding Region Sequence Obtained by PacBio Single-Molecule Real-Time Sequencing

Viruses, 2021
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is the causal agent of the COVID-19 pandemic that emerged in late 2019. The outbreak of variants with mutations in the region encoding the spike protein S1 sub-unit that can make them more

Fenestelloid clades of the Cucurbitariaceae [PDF]

Persoonia - Molecular Phylogeny and Evolution of Fungi, 2020
Fresh collections and their ascospore and conidial isolates backed up by type studies and molecular phylogenetic analyses of a multigene matrix of partial nuSSU-, complete ITS, partial LSU rDNA, rpb2, tef1 and tub2 sequences were used to evaluate the boundaries and species composition of Fenestella and related genera of the Cucurbitariaceae.

Genomic Diversity of SARS-CoV-2 in Algeria and North African Countries: What We Know So Far and What We Expect?

Microorganisms, 2022
Here, we report a first comprehensive genomic analysis of SARS-CoV-2 variants circulating in North African countries, including Algeria, Egypt, Libya, Morocco, Sudan and Tunisia, with respect to genomic clades and mutational patterns. As of December 2021,

Development of a Multiplex RT-qPCR for the Detection of Different Clades of Avian Influenza in Poultry

Viruses, 2020
Since the initial detection of H5N1, a highly pathogenic avian influenza (HPAI) virus, in 1996 in China, numerous HPAI H5 lineages have been classified, and they continue to pose a threat to animal and human health.

Characterization of community-acquired Clostridioides difficile strains in Israel, 2020–2022

Frontiers in Microbiology, 2023
BackgroundThe prevalence of community-acquired Clostridioides difficile infection (CA-CDI) has been rising, due to changes in antibiotics prescribing practices, emergence of hypervirulent strains and improved diagnostics.

Ecogenomics of the SAR11 clade [PDF]

Environmental Microbiology, 2019
Summary Members of the SAR11 clade, despite their high abundance, are often poorly represented by metagenome‐assembled genomes. This fact has hampered our knowledge about their ecology and genetic diversity. Here we examined 175 SAR11 genomes, including 47 new single‐amplified genomes. The presence of the first genomes associated with

Human neutralising antibodies elicited by SARS‐CoV‐2 non‐D614G variants offer cross‐protection against the SARS‐CoV‐2 D614G variant

Clinical & Translational Immunology, 2021
Objectives The emergence of a SARS‐CoV‐2 variant with a point mutation in the spike (S) protein, D614G, has taken precedence over the original Wuhan isolate by May 2020.
