Such infections typically involve multiple species of bacteria, some strict anaerobes, some strict aerobes and others that are facultative anaerobes (i.e., able to grow aerobically or anaerobically). The polymicrobial nature of infections involving anaerobic bacteria is apparent in infections of the ...

O6 and O18 antigens were required for survival in human serum, the role of the capsule was less clear and linked to O antigen type. In contrast, both the K1 and K2 capsular antigens provided a survival advantage to UPEC in whole blood. In the mouse urinary tract, mutation of the O6 ...
Inhibition of virulence phenotypes ispartially mediated through biofilm components; the exopolysaccharidescellulose and capsule, as well as the biofilm regulator CsgD. C-di-GMPalso interferes with the secretion of SopE2, a S. typhimurium effectorprotein, as well as of flagellin, both of which are...
Neisseria meningitidis biofilms: The role of capsule and two-partner secretion. meningitidis biofilms on HBE cells by investigating the role of the HrpA protein in biofilm formation. HrpA is the secreted component of a two-partner ... RB Neil - The University of Iowa.; 被引量: 0发表: 2009...
In addition, women with a history of UTI seem to have an increased risk of recurrency within 3 to 4 months2. UPEC have the ability to cause symptomatic UTI by utilizing virulence factors such as type-1 fimbriae and P-fimbriae, capsule, lipopolysaccharides (LPS), α-hemolysin, iron ...
Discuss the significance of a capsule on particular strains of E. coli that causes digestive tract infection vs. strains of E. coli that cause urinary tract infections. What is the significance of the discovery of transformation in bacteria to micr...
Spatial and Temporal Deposition of Adhesive Extracellular Polysaccharide Capsule and Fimbriae by Hyphomonas Strain MHS-3 Hyphomonas strain MHS-3, a member of a genus of primary colonizers of surfaces immersed in murine water, synthesizes two structures that mediate adhesion t...

As determined by using selective antimicrobial therapy and quantitative cultures of abscesses induced in mice, possession of a capsule generally made Gram-negative anaerobic rods more important than their aerobic counterparts. Synergistic potentials were seen between encapsulated Gram-negative anaerobic rods ...
