Abstract:
... Plastic pollution has now been found within multiple ecosystems across the globe. Characterisation of microbial assemblages associated with marine plastic, or the so-called ‘plastisphere’, has focused predominantly on plastic in the epipelagic zone. Whether this community includes taxa that are consistently enriched on plastic compared to surrounding non plastic surfaces is unresolved, as are the ...

Abstract:
... Thorough understanding of the initial colonization process of human intestines is important to optimize the prevention of microbiota-associated diseases, and also to further improve the current microbial therapies. In recent years, therefore, colonization of the human gut has gained renewed interest. However, due to a lack of standardization of life events that might influence this early colonizat ...

Abstract:
... Antibiotic resistance is a health and socioeconomic crisis recognized as a serious threat affecting humans worldwide. Overuse of antibiotics enhances the spread of multidrug-resistant bacteria, causing drug-resistant infections which can be difficult to treat. This resistance, mostly of the acquired type, is thus a major clinical issue. Acquired resistance can occur by horizontal transfer of genes ...

Abstract:
... Nonpathogenic strain ARK-1 of Rhizobium vitis has antagonistic activity against a tumorigenic (Ti) strain of R. vitis and works as a biocontrol agent, but the temporal dynamics of the bacterial colonization in plants needs to be understood. Here we showed that the incidence of galls induced by Ti strain was reduced to about 60% when both upper and lower positions on the grapevine stem were inocula ...

Abstract:
... l‐Fucose, as a monosaccharide in nature, plays a crucial role in bacteria colonization. Escherichia coli (E. coli), as a common microorganism in environment, utilize bacterial flagellar motor to drive the rotation of flagella, which is regulated by chemotactic signal transduction signals. Yet the effect of l‐fucose to bacterial motility remains unclear. The effect of l‐fucose on the swimming motil ...
