Bacterial biofilms are structured multicellular communities involved in a broad range of infections. Knowing how free-swimming bacteria adapt their motility mechanisms near surfaces is crucial for understanding the transition between planktonic and biofilm phenotypes. By translating microscopy movies into searchable databases of bacterial behavior, we identified fundamental type IV pili-driven ...
Porphyromonas gingivalis (Pg) fimbriae, in addition to lipopolysaccharide, are involved in the pathogenesis of periodontal disease. At the same time, bioactive compounds such as fibronectin (FN) and melatonin in saliva and gingival crevicular fluid have been reported to exert a preventive effect against periodontitis. Here, we review current knowledge regarding the potent inhibitory effects of ...
The genetic organization of the foc gene cluster has been studied; six genes involved in the biogenesis of F1C fimbriae were identified. focA encodes the major fimbrial subunit, focC encodes a product that is indispensable for fimbria formation, focG and focH encode minor fimbrial subunits, and focI encodes a protein which shows similarities to the subunit protein FocA. Apart from the FocA majo...
An immunofluorescence assay was developed to study fimbrial phase variation in a pyelonephritogenic Escherichia coli strain, KS71. By using fluorochrome-labeled antibodies specific for either P, type-1C, or type-1 fimbriae of strain KS71, it was shown that in a broth culture of strain KS71 the fimbrial types mostly occurred on different cells. Only 9% of the cells carried more than one fimbrial...
