Transcriptional profiling of zebrafish identifies host factors controlling susceptibility to Shigella flexneri [PDF]

Shigella flexneri is a human-adapted pathovar of Escherichia coli that can invade the intestinal epithelium, causing inflammation and bacillary dysentery. Although an important human pathogen, the host response to S. flexneri has not been fully described.

Specific blood group antibodies inhibit Shigella flexneri interaction with human cells in the absence of spinoculation

, 2020
The classical models of investigating Shigella flexneri adherence and invasion of tissue culture cells involve either bacterial centrifugation (spinoculation) or the use of AfaE adhesin to overcome the low infection rate observed in vitro.

Assembly and arrangement of the type three secretion system of "yersinia enterocolitica" [PDF]

, 2014
The type three secretion system (T3SS) is a bacterial weapon found in many Gram-negative bacteria. It consists out of a needle like structure called injectisome, which enables bacteria to inject effector proteins into eukaryotic cells. The injectisome is

Aloe vera in Food Preservation: Harnessing Bioactive Constituents for Clean‐Label Innovation and Safety Assurance

Food Safety and Health, EarlyView.
Aloe vera‐derived biopolymers and nanoformulations enhance antimicrobial, antioxidant, and barrier functions in clean‐label edible coatings and films, whereas safety‐critical anthraquinone thresholds and regulatory constraints shape their translational potential.

Aging and periodontitis increase brain dissemination of oral bacteria

Journal of Periodontology, EarlyView.
Abstract Background The microbiome is a dynamic system that changes throughout life. Studies have revealed the relationship between periodontal disease and the oral microbiota; however, the impact of periodontal disease on the expression of senescence markers and on the inflammaging of the oral and systemic microbiome remains unclear.

From Data to Knowledge to Wisdom: Lessons Learned From the Vancouver Rat Project

Integrative Zoology, EarlyView.
A synthesis of 15 years of research conducted by the Vancouver Rat Project revealed that: (1) Pathogen ecology within rat colonies is the result of complex interactions among rats, pathogens, and vectors. (2) Local and global population structures influence rat and pathogen ecology.

Chain‐Length Regulation by WzzE Is Necessary for, but Genetically Separable From, Cyclic Enterobacterial Common Antigen Synthesis

Molecular Microbiology, EarlyView.
Here, we demonstrate that polysaccharide chain length regulation plays a distinct role in enabling formation of a cyclic molecule important for the bacterial cell surface. However, this function is necessary, but not sufficient for the cyclic molecule's biosynthesis.
