In this report, we present a draft sequence of the genome of Lactobacillus rhamnosus strain 2166, a potential novel probiotic. Genome annotation and read mapping onto a reference genome of ...L. rhamnosus strain GG allowed for the identification of the differences and similarities in the genomic contents and gene arrangements of these strains.
This report describes a draft genome sequence of Lactobacillus crispatus 2029. The reads generated by the Ion Torrent PGM were assembled into contigs with a total size of 2.2 Mb. The data were ...annotated using the NCBI GenBank and RAST servers. A comparison with the reference strain revealed specific features of the genome.
Different common factors contribute to the antagonistic properties of Lactobacillus gasseri toward various pathogens. However, there is strain-to-strain variation in the probiotic properties of this ...bacterium. The draft genome sequence of L. gasseri strain 2016 determined in this study will assist in understanding the genetic basis for such variation.
The completion of the
Campylobacter jejuni genome sequence is a landmark in
Campylobacter research. Discoveries directly arising from these data include the identification of a capsular ...polysaccharide, extensive capacity for phase variable gene expression and lipo-oligosaccharide structural phase variation. The recent identification of a unique system of general protein glycosylation in
C. jejuni, a
C. jejuni protein that is translocated into eukaryotic cells, and plasmid-encoded components of a putative type IV secretion system are likely to be significant in terms of the host–pathogen interaction.
Here, we report a draft genome sequence of the strain

acquired from the Belgian Coordinated Collections of Microorganisms. The genus

Microbial cell surface glycans in the form of glycolipids and glycoproteins frequently play important roles in cell–cell interaction and host immune responses. Given the likely importance of these ...surface structures in the survival and pathogenesis of
Campylobacter jejuni, a concerted effort has been made to characterise these determinants genetically and structurally since the genome was sequenced in 2000. We review the considerable progress made in characterising the
Campylobacter glycome including the lipooligosaccharide (LOS), the capsule and
O- and
N-linked protein glycosylation systems, and speculate on the roles played by glycan surface structures in the life-cycle of
C. jejuni.
In certain conditions Campylobacter jejuni cells are capable of changing their cell shape from a typically spiral to a coccoid form (CF). By similarity to other bacteria, the latter was initially ...considered to be a viable but non-culturable form capable of survival in unfavourable conditions. However, subsequent studies with C. jejuni and closely related bacteria Helicobacter pylori suggested that CF represents a non-viable, degenerative form. Until now, the issue on whether the CF of C. jejuni is viable and infective is highly controversial. Despite some preliminary experiments on characterization of CF cells, neither biochemical mechanisms nor genetic determinants involved in C. jejuni cell shape changes have been characterized. In this review, we highlight known molecular mechanisms and genes involved in CF formation in other bacteria. Since orthologous genes are also present in C. jejuni, we suggest that CF formation in these bacteria is also a regulated and genetically determined process. A possible significance of CF in the lifestyle of this important bacterial pathogen is discussed.
Adhesion to host cells is an important step in pathogenesis of Campylobacter jejuni, which is the most prevalent bacterial cause of human gastroenteritis worldwide. In contrast to other bacteria such ...as E. coli and Salmonella, adherence of C. jejuni is not mediated by fimbria or pili. A number of C. jejuni adhesion-related factors have been described. However, the results obtained by different researchers in different laboratories are often contradictory and inconclusive, with only some of the factors described being confirmed as true adhesins. In this review, we present the current state of studies on the mechanisms of attachment of C. jejuni to host cells.
