Bacterial cells in a biofilm are encased in a self-synthesized, extracellular hydrogel matrix that holds the cells together in a mass and firmly attaches the bacterial mass to the underlying surface. Surface-associated colonies of bacteria known as biofilms play a role in the pathogenesis of many chronic infections.
Biofilm formation may have relevance to the colonization and pathogenesis of A. Our findings suggest that PGA functions as a major biofilm adhesin in A. Treatment of IA5 biofilms with dispersin B rendered them more sensitive to killing by ampicillin. A pgaC mutant of strain IA5 failed to form biofilms in vitro, as did wild-type strains IA1 and IA5 when grown in broth supplemented with the PGA-hydrolyzing enzyme dispersin B.
pleuropneumoniae field isolates (serotypes 1, 5 and 7). pleuropneumoniae reference strains (serotypes 1-12) and 76 out of 77 A. PCR analyses indicated that a gene encoding the PGA-specific glycoside transferase enzyme PgaC was present on the chromosome of 15 out of 15 A. These structures were nearly identical to those of biofilm matrix polysaccharides produced by Escherichia coli, Staphylococcus aureus and S. A small percentage of the GlcNAc residues in each polysaccharide were N-deacetylated. Both strains produced matrix polysaccharides consisting of linear chains of N-acetyl-D-glucosamine (GlcNAc) residues in β(1,6) linkage (poly-β-1,6-GlcNAc or PGA). pleuropneumoniae field isolates IA1 and IA5 (serotypes 1 and 5, respectively), and determined their chemical structures by using NMR spectroscopy. We purified matrix polysaccharides from biofilms produced by A.
