A comparison of super‐resolution microscopy techniques for imaging tightly packed microcolonies of an obligate intracellular bacterium

Journal of Microscopy, EarlyView.
Abstract Conventional optical microscopy imaging of obligate intracellular bacteria is hampered by the small size of bacterial cells, tight clustering exhibited by some bacterial species and challenges relating to labelling such as background from host cells, a lack of validated reagents, and a lack of tools for genetic manipulation.

Levels of matrix metalloproteinase‐1 (MMP‐1), MMP‐2, MMP‐3, osteopontin, pentraxin‐3, and thymic stromal lymphopoietin in crevicular fluid samples from peri‐implantitis, periodontitis, and healthy sites

Journal of Periodontal Research, EarlyView.
Elevated levels of MMP‐1, MMP‐2, MMP‐3, OPN, and TSLP were detected at sites affected by periodontitis and peri‐implantitis compared to sites with healthy teeth and implants. The cytokine OPN may serve as a biomarker for periodontitis, whereas the proteolytic enzyme MMP‐2 and the cytokine TSLP might be potential biomarkers for both periodontitis and ...

Salivary Proteomics for Detecting Novel Biomarkers of Periodontitis: A Systematic Review

Journal of Periodontal Research, EarlyView.
Untargeted salivary proteomics identified promising biological molecules consistently over‐ or under‐expressed in periodontitis patients compared to periodontally healthy subjects, but further targeted approaches are required for their validation. ABSTRACT Aim Salivary content is regarded as a powerful diagnostic window for oral and systemic diseases ...

Metabolomic Profiles of Oral Rinse Samples to Distinguish Severe Periodontitis Patients From Non‐Periodontitis Controls

Journal of Periodontal Research, EarlyView.
Metabolomic fingerprints analyzed from oral rinses are able to distinguish between severe periodontitis (stage III/IV) patients and non‐periodontitis controls. ABSTRACT Aims To explore the potential of metabolomic profiles of oral rinse samples to distinguish between patients with severe periodontitis (stage III/IV) and non‐periodontitis controls. This

FlhG Cooperates With the Cell Cycle Regulator GpsB to Confine Peritrichous Flagella in B. subtilis

Molecular Microbiology, EarlyView.
FlhG (orange, with activator helix in green) regulates peritrichous flagellation in Bacillus subtilis by interacting with the C‐ring protein FliY (gray, N‐terminus in red) and the cell wall regulator GpsB (N‐terminus in blue, C‐terminus in red). GpsB recruits PBP1 for peptidoglycan synthesis, linking flagellar assembly to cell wall biosynthesis.

Staphylococcus aureus COL: An Atypical Model Strain of MRSA That Exhibits Slow Growth and Antibiotic Tolerance due to a Mutation in PRPP Synthetase

Molecular Microbiology, EarlyView.
COL is an unusual “model” strain of Staphylococcus aureus that exhibits slow growth and multidrug antibiotic tolerance. This phenotype is primarily due to a mutation in Prs, which synthesizes the core metabolite phosphoribosyl pyrophosphate (PRPP). Introduction of the COL Prs allele into the antibiotic‐susceptible strain Newman confers tolerance, while
