Discriminating Between Living and Dead Bacteria With a Field‐Effect Transistor Based on Nano‐Channels

open access: yesSmall, EarlyView.
Bacterial viability is determined in a complex environment with a field‐effect biological transistor with a limit of detection of a single bacterium. Living, antibiotic‐treated, thermally denatured, and inhibited E. coli generate distinct electrical signatures, enabling label‐free single‐cell detection and providing new opportunities for rapid ...

Characterization of the dynamic microbiome evolution across thrips species

open access: yesInsect Science, EarlyView.
Comprehensive survey of the microbiome in thrips. The dominant bacterial genera found in thrips include intracellular ones, such as Wolbachia and Spiroplasma, and extracellular ones, including Serratia, Pantoea, and Acinetobacter. We isolated and sequenced high‐quality genomes of two dominant symbionts, Pantoea dispersa and Serratia marcescens.

Insights into the Functions of a Prophage Recombination Directionality Factor

open access: yesViruses, 2012
Recombination directionality factors (RDFs), or excisionases, are essential players of prophage excisive recombination. Despite the essentially catalytic role of the integrase in both integrative and excisive recombination, RDFs are required to direct ...

Effect of the microbiome on pathogen susceptibility across four Drosophilidae species

open access: yesInsect Science, EarlyView.
Four Drosophilidae species were used to investigate how variation in the host microbiome influences susceptibility to infection. Microbial composition and abundance differed among species and treatments. The effects of microbiome manipulation on host survival were both species‐ and pathogen‐specific.

Bacteriocinogeny and Lysogeny in the Genus Pseudomonas [PDF]

open access: yesJournal of General Microbiology, 1965
SUMMARY: Bacteriocinogeny and lysogeny have been investigated in strains of Pseudomonas aeruginosa, P. fluorescens and P. ovalis. The 39 strains of P. aeruginosa were all bacteriocinogenic and 32 were also lysogenic. No bacteriocine production was detected in 8 strains of P. fluorescens, although 3 were lysogenic. The one strain of P.

The tryptophan prenyltransferase ComQ from Bacillus subtilis 168 can prenylate daptomycin at Trp1

open access: yesThe FEBS Journal, EarlyView.
ComQ168 from Bacillus subtilis 168 catalyzes C‐terminal tryptophan farnesylation of ComX to generate a competence‐inducing pheromone. Recombinant ComQ168 also modifies cyclic peptides, including Daptomycin, likely at the N‐terminal tryptophan. Structural modeling highlights a C‐terminal binding region, supporting substrate promiscuity and establishing ...

Lysogeny and Colicinogeny in Escherichia coli [PDF]

open access: yesJournal of General Microbiology, 1961
SUMMARY: One hundred and eighty-three strains of Escherichia coli were examined for lysogeny and colicinogeny: 40.4 % were neither lysogenic nor colicinogenic; 31.1 % were only colicinogenic; 13.1% were only lysogenic; 15.2% were lysogenic and colicinogenic.

RING E3 ligase SNIPER8 functions redundantly with three close homologs to regulate the turnover of transcriptional co‐repressor TPR1

open access: yesJournal of Integrative Plant Biology, EarlyView.
The Arabidopsis E3 ligase SNIPER8 negatively regulates immunity by promoting ubiquitination and proteasomal degradation of the transcriptional corepressor TOPLESS‐RELATED1, limiting excessive immune responses, maintaining immune homeostasis, and balancing defense activation and normal plant growth.

Viruses, Periodontitis, and Systemic Diseases

open access: yesJournal of Periodontal Research, EarlyView.
This narrative review aimed to summarize current evidence on the viral involvement in periodontitis and its relevance for systemic diseases. The oral cavity acts as an active viral reservoir and dissemination platform, where virus–microbiome interactions may promote dysbiosis, periodontitis progression, and systemic inflammatory effects, while the ...
