Ebselen Not Only Inhibits Clostridioides difficile Toxins but Displays Redox-Associated Cellular Killing

open access: yesMicrobiology Spectrum, 2021
Ebselen, a reactive organoselenium compound, was shown to inhibit toxins TcdA and TcdB by covalently binding to their cysteine protease domains. It was suggested that ebselen lacked antimicrobial activity against Clostridioides difficile.

RNAi in the Rhizarian Phytopathogen Plasmodiophora brassicae: The Causal Agent of Clubroot Disease in Cruciferous Crops

open access: yesAdvanced Science, EarlyView.
This study uncovers an unusual RNAi pathway in the rhizarian pathogen Plasmodiophora brassicae. In the absence of Dicer, a Drosha‐like RNase III protein supports the biogenesis of predominant 21‐nt small RNAs, and two Argonaute proteins mediate small RNA‐guided silencing.

Emergent Spinning and Orbital Motion in Clustered Wind‐Assisted Flyers

open access: yesAdvanced Science, EarlyView.
Inspired by natural snowflake geometries, paper‐cut flyers exhibit geometry‐defined spinning and orbital motions during cluster formation in a wind tunnel. Collective flights of multiple paperflakes reveal dynamic clustering, fragmentation, and continuously evolving spin behaviors.

Characterization of Putative Sporulation and Germination Genes in Clostridium perfringens Food-Poisoning Strain SM101

open access: yesMicroorganisms, 2022
Bacterial sporulation and spore germination are two intriguing processes that involve the expression of many genes coherently. Phylogenetic analyses revealed gene conservation among spore-forming Firmicutes, especially in Bacilli and Clostridia.

Production of spores by Cercosporella herpotrichoides

open access: yes, 1953
Eyespot lesions on young wheat plants in the field regularly produced conidia of Cercosporella herpotrichoides Fron in early spring. Conidia were not produced on mature growing plants, but after ploughing, lesions on infected straws spored freely ...
