AI Article Synopsis
Article Abstract
Flagellin glycosylation was identified in Bacillus sp. PS3 and Geobacillus stearothermophilus. In vivo complementation showed that these flagellin genes did not restore the motility of a Bacillus subtilis flagellin mutant, whereas the genes encoding non-glycosylated flagellin from Geobacillus kaustophilus and Bacillus sp. Kps3 restored motility. Moreover, four types of flagellins expressed in B. subtilis were not glycosylated. We speculate that glycosylation is required for flagellar filament assembly of these bacilli.

The discovery at the end of the 20th century of genes that induce cell death revolutionised the biocontaintment of genetically manipulated bacteria for environmental or agricultural applications. These bacterial 'killer' genes were then assayed for their potential to target and control malignant cells in human cancers. The identification of the bacteriomes in different human organs and tissues, coupled with the observation that bacteria tend to accumulate near tumours, has opened new avenues for anti-cancer strategies.

Bacterial flagellin, a potent intestinal innate immune activator, prevents murine rotavirus (RV) infection independent of adaptive immunity and interferons. The flagellin-induced immunity is mediated by Toll-like receptor (TLR5) and Nod-like receptor C4 (NLRC4), which elicit the production of interleukins 22 (IL-22) and IL-18, respectively. Here, we assessed whether a high abundance of flagellin at the time of vaccination would negatively affect the oral RV vaccine take.

The global public health risk posed by Salmonella Kentucky (S. Kentucky) is rising, particularly due to the dissemination of antimicrobial resistance genes in human and animal populations. This serovar, widespread in Africa, has emerged as a notable cause of non-typhoidal gastroenteritis in humans.

Vibrio parahaemolyticus propels itself through liquids using a polar flagellum and efficiently swarms across surfaces or viscous environments with the aid of lateral flagella. H-NS plays a negative role in the swarming motility of V. parahaemolyticus by directly repressing the transcription of the lateral flagellin gene lafA.
