Hcp Proteins of the Type VI Secretion System Promote Avian Pathogenic DE205B (O2:K1) to Induce Meningitis in Rats.

Avian pathogenic (APEC) is an important extra-intestinal pathogenic (ExPEC), which often causes systemic infection in poultry and causes great economic loss to the breeding industry. In addition, as a major source of human ExPEC infection, the potential zoonotic risk of APEC has been an ongoing concern. Previous studies have pointed out that APEC is a potential zoonotic pathogen, which has high homology with human pathogenic such as uro-pathogenic (UPEC) and neonatal meningitis (NMEC), shares multiple virulence factors and can cause mammalian diseases.

Extraintestinal Pathogenic Utilizes Surface-Located Elongation Factor G to Acquire Iron from Holo-Transferrin.

Extraintestinal pathogenic Escherichia coli (ExPEC) can cause systemic infections in both humans and animals. As an essential nutrient, iron is strictly sequestered by the host. Circumventing iron sequestration is a determinant factor for ExPEC infection.

Extraintestinal pathogenic utilizes the surface-expressed elongation factor Tu to bind and acquire iron from holo-transferrin.

Extraintestinal pathogenic (ExPEC) is a common anthropozoonotic pathogen that causes systemic infections. To establish infection, ExPEC must utilize essential nutrients including iron from the host. Transferrin is an important iron source for multiple bacteria.

Mechanisms of interactions between bacteria and bacteriophage mediate by quorum sensing systems.

Bacteriophage (phage) and their host bacteria coevolve with each other over time. Quorum sensing (QS) systems play an important role in the interaction between bacteria and phage. In this review paper, we summarized the function of QS systems in bacterial biofilm formation, phage adsorption, lysis-lysogeny conversion of phage, coevolution of bacteria and phage, and information exchanges in phage, which may provide reference to future research on alternative control strategies for antibiotic-resistant and biofilm-forming pathogens by phage.

Novel Host Recognition Mechanism of the K1 Capsule-Specific Phage of : Capsular Polysaccharide as the First Receptor and Lipopolysaccharide as the Secondary Receptor.

K1 capsule-specific phages of Escherichia coli have been reported in recent years, but the molecular mechanism involved in host recognition of these phages remains unknown. In this study, the interactions between PNJ1809-36, a new K1-specific phage, and its host bacterium, E. coli DE058, were investigated.

The complete chloroplast genome sequence of medicinal plant: (Caryophyllaceae).

is a medicinal plant. Its complete chloroplast genome sequence is 149,570 bp in length, containing 126 complete genes, including 84 protein-coding genes (84 PCGs), 8 ribosomal RNA genes (8 rRNAs), and 34 tRNA genes (34 tRNAs). The overall GC content of cp DNA is 34.

Factor H Is Bound by Outer Membrane-Displayed Carbohydrate Metabolism Enzymes of Extraintestinal Pathogenic and Contributes to Opsonophagocytosis Resistance in Bacteria.

Extraintestinal pathogenic (ExPEC) causes bloodstream infections in humans and animals. Complement escape is a prerequisite for bacteria to survive in the bloodstream. Factor H (FH) is an important regulatory protein of the complement system.
