Clade-specific chromosomal rearrangements and loss of subtelomeric adhesins in Candida auris

open access: yesGenetics, 2021
Candida auris is an emerging fungal pathogen of rising concern due to global spread, the ability to cause healthcare-associated outbreaks, and antifungal resistance. Genomic analyses revealed that early contemporaneously detected cases of C.

Homoplasy and Clade Support [PDF]

open access: yesSystematic Biology, 2009
Distinguishing phylogenetic signal from homoplasy (shared similarities among taxa that do not arise by common ancestry) is an implicit goal of any phylogenetic study. Large amounts of homoplasy can interfere with accurate tree inference, and it is expected that common measures of clade support, including bootstrap proportions and Bayesian posterior ...

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

open access: yesMicroorganisms, 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,

Completion of the AAV Structural Atlas: Serotype Capsid Structures Reveals Clade-Specific Features

open access: yesViruses, 2021
The capsid structures of most Adeno-associated virus (AAV) serotypes, already assigned to an antigenic clade, have been previously determined. This study reports the remaining capsid structures of AAV7, AAV11, AAV12, and AAV13 determined by cryo-electron

Genome Mining Enabled by Biosynthetic Characterization Uncovers a Class of Benzoxazolinate‐Containing Natural Products in Diverse Bacteria

open access: yesAngewandte Chemie, Volume 134, Issue 51, December 19, 2022., 2022
Benzoxazolinate is a rare bis‐heterocyclic moiety that interacts with proteins and DNA. It was found that a putative acyl AMP‐ligase mediates the last cyclization step to afford benzoxazolinate. The enzyme was then used as a probe for genome mining, which led to the discovery of a new class of benzoxazolinate‐containing compounds in diverse bacteria ...

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

open access: yesViruses, 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.

Diversity in the Circulation of Influenza A(H3N2) Viruses in the Northern Hemisphere in the 2018–19 Season

open access: yesVaccines, 2021
While vaccination is considered the most effective means to prevent influenza infection, its seasonal effectiveness varies, depending on the circulating influenza strains.

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

open access: yesClinical & 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.
