The Synergy Between a Silver‐Ruthenium Antimicrobial and Aminoglycosides Is Based on Severe Macromolecular Damage

Molecular Microbiology, EarlyView.
AGXX enhances aminoglycoside activity against multidrug‐resistant pathogens such as uropathogenic Escherichia coli by increasing reactive oxygen species, causing protein aggregation and DNA damage. This effect is reduced by oxygen limitation or antioxidants. Polyphosphate protects cells from oxidative damage.

Temperature and precipitation differently influence entomological indices based on larval or adult sampling

Medical and Veterinary Entomology, EarlyView.
Larval indices, especially house infestation index (HI) and breteau index (BI), were significantly associated with temperature and precipitation, indicating that warmer and wetter conditions increase Aedes aegypti breeding‐site positivity. Adult indices, trap positivity index (TPI) and adult density index (ADI) showed no significant association with ...

Oral Phageome as Potential Modulators of Periodontal Dysbiosis. A Systematic Review

Oral Diseases, EarlyView.
ABSTRACT Introduction The oral phageome, comprising bacteriophages inhabiting the oral cavity, has been proposed as a potential modulator of periodontal health and disease. This systematic review synthesizes current evidence on interactions between bacteriophages, key periodontal bacteria, and the host in periodontitis.

Ion Channel Dysfunction and Therapeutic Targeting in Salivary Gland Disorders

Oral Diseases, EarlyView.
ABSTRACT Objective Salivary gland hypofunction and xerostomia represent major clinical complications of radiation therapy, autoimmune disorders such as Sjögren's disease, and inherited epithelial ion transport defects. This review integrates current knowledge on ion channel dysfunction as a central mechanistic driver of salivary gland pathology and ...

Serotype-converting bacteriophages and O-antigen modification in Shigella flexneri

Trends in Microbiology, 2000
O-antigen modification (serotype conversion) in Shigella flexneri, which is an important virulence determinant, is conferred by temperate bacteriophages. Several serotype-converting phages have been isolated and preliminary characterization has identified the genes involved in O-antigen modification, and has also provided insight into the molecular ...

O-serotyping Providencia alcalifaciens

Journal of Clinical Microbiology, 1979
The O-serotyping scheme for Providencia was tested on Providencia alcalifaciens isolates collected mostly from two hospitals. The specificites of the somatic (O) antigens of P. alcalifaciens were found to be different from those of Providencia stuartii, and separation of the Providencia typing scheme to allow separate typing of each species led to more

O serotyping scheme for Enterobacter cloacae

Journal of Clinical Microbiology, 1983
A serotyping scheme for Enterobacter cloacae based on heat-stable somatic antigens is described. A total of 28 antisera were prepared in rabbits, and titers of agglutinins were high (greater than 640). Some cross-reactions were observed, and 11 sera required absorption before routine use.
