Apr 17, 2024 · Many Gram-negative bacteria use type Ⅲ secretion system (T3SS) to inject effector proteins and subvert host signaling pathways, facilitating the growth, survival, and virulence. Notably, some bacteria harbor multiple distinct T3SSs with different functions. An extraordinary T3SS, the Escherichia coli Type III Secretion System 2 (ETT2), is widespread among Escherichia coli (E. coli) strains ...
4 days ago · E. coli cells swim clockwise and leave circular trajectories at solid and planar surfaces, although they swim in a random-walk manner in a free aqueous environment [28, 29]. When the flagellar bundle rotates to the left near the surface, the cell body rotates to the right, resulting in a clockwise and circular motion of the cell.

Apr 10, 2024 · In our recent study, we conducted phenotypic and transcriptomic profiling of ElyC-defective E. coli cells grown at 37C and 21C, compared to wild-type cells. While elyC mutant cells grow similarly to wild-type cells at 37C, microscopy revealed altered cell morphology due to ElyC's absence.
Apr 5, 2024 · Diarrheagenic Escherichia coli. Escherichia coli (E. coli) is a bacterium commonly found in the gut of humans and warm-blooded animals. Most E. coli are normal flora or commensals found in the intestinal tract. It is a gram-negative short rod, a member of the family Enterobacteriaceae.
1 day ago · The three-dimensional swimming tracks of motile microorganisms can be used to identify their species, which holds promise for the rapid identification of bacterial pathogens. The tracks also provide detailed information on the cells’ responses to external stimuli such as chemical gradients and physical objects. Digital holographic microscopy (DHM) is a well-established, but computationally ...

Apr 20, 2024 · Gram-negative bacteria, similar to Gram-positive bacteria, stain purple in the initial step of the reaction. However, in cells with thin peptidoglycan layers, the dye is subsequently removed by the solvent; in the final step, these cells acquire a pink or red colour, revealing their identity as Gram-negative bacteria.
