Phylodynamic pattern of genetic clusters, paradigm shift on spatio-temporal distribution of clades, and impact of spike glycoprotein mutations of SARS-CoV-2 isolates from India

open access: yesJournal of Global Infectious Diseases, 2021
Introduction: The COVID-19 pandemic is associated with high morbidity and mortality, with the emergence of numerous variants. The dynamics of SARS-CoV-2 with respect to clade distribution is uneven, unpredictable and fast changing.

The Environmental Clade LKM11 and Rozella Form the Deepest Branching Clade of Fungi [PDF]

open access: yesProtist, 2010
Previous environmental surveys of eukaryotic diversity using the small subunit ribosomal RNA (SSU rRNA) gene have revealed many clone sequences that branch near the base of Fungi. In this work, we demonstrate that many of these sequences, including those of the environmental clade LKM11, form a monophyletic and strongly supported group that also ...

An emergent clade of SARS-CoV-2 linked to returned travellers from Iran

open access: yesbioRxiv, 2020
The SARS-CoV-2 epidemic has rapidly spread outside China with major outbreaks occurring in Italy, South Korea and Iran. Phylogenetic analyses of whole genome sequencing data identified a distinct SARS-CoV-2 clade linked to travellers returning from Iran ...

Candida albicansclades [PDF]

open access: yesFEMS Immunology & Medical Microbiology, 2003
DNA fingerprinting with the complex probe Ca3 has revealed the following five Candida albicans clades: group I, group II, group III, group SA and group E. These groups exhibit geographical specificity. Group SA is relatively specific (i.e., highly enriched) to South Africa, group E is relatively specific to Europe, and group II is absent in the ...

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

open access: yesFrontiers 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.

SARS-CoV-2 genomic surveillance in Taiwan revealed novel ORF8-deletion mutant and clade possibly associated with infections in Middle East

open access: yesEmerging Microbes and Infections, 2020
Taiwan experienced two waves of imported infections with Coronavirus Disease 2019 (COVID-19). This study aimed at investigating the genomic variation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Taiwan and compared their ...
