Jul 10, 2017 · Preseptal PG synthesis has been described in E. coli (de Pedro et al., 1997) and C. crescentus (Aaron et al., 2007) and appears to be important during a larger part of the cell cycle in the latter. Many open questions remain, although two different mechanisms have been described for this preseptal PG incorporation in E. coli.
Dec 30, 2016 · Rod-shaped cells are better at colonizing the base of the community and its expanding edges, whereas round cells dominate the upper surface. We show that the same patterns occur in colonies of Escherichia coli, using strains with different shapes. Our work suggests that cell shape is a major determinant of patterning and evolutionary fitness ...
Jan 1, 2024 · Isolates from pediatric recollection bags were excluded. Patients with E coli filamented cell morphology, mucoid colony phenotype or biofilm production detected were considered cases. Patients where the E coli isolate did not have any of these characteristics were considered controls. Demographic data (age, sex, underlying disease) were ...

Jan 1, 2014 · Abstract. Escherichia coli is a non-spore-forming, Gram-negative bacterium, usually motile by peritrichous flagella. Escherichia coli is the most common cause of acute urinary tract infections as well as urinary tract sepsis. It has also been known to cause neonatal meningitis and sepsis and also abscesses in a number of organ systems.
May 11, 2020 · Progress in understanding these processes now runs almost in parallel between B. subtilis and its Gram-negative comparator, Escherichia coli. Bacillus genetics and cell-biology methods have also made the organism popular for more general studies of cell physiology and biochemistry, as well as alternative morphogenic processes, such as biofilm ...
The E. coli reference strain BD1428, alias X474, undergoes colony mor- phology phase variation (Fig. 1). Two phase-variant forms of the strain were previously reported, with interconversion rates ...
