Cup fimbriae play an important role in cell-to-cell interactions in the early stage of biofilm formation (Wei and Ma, 2013). The composition and functions of EPSs in the P. aeruginosa biofilm were highlighted in several reviews (Flemming and Wingender, 2010; Moradali et al., 2017). The Motile–Sessile Lifestyle Switch

Finally, Cup fimbriae‐encoding cupB and cupC genes are regulated by the RocSAR signalling system, which relays on the activity of yet another PDE, RocR, for modulating adhesion and biofilm formation (Kulasekara et al. Acinetobacter baumannii is a nosocomial pathogen of increasing importance due to its multiple resistance to antibiotics and ability to survive in the hospital environment linked to its capacity to form biofilms. To fully characterize the contribution of AdeABC, AdeFGH, and AdeIJK resistance-nodulation-cell division (RND)-type efflux systems to acquired and intrinsic resistance, we constructed Organization of the cup gene clusters. The three cup gene clusters have been represented to scale.

Strikingly, Northern blot analysis showed that in all three cases, only a transcript with a size corresponding to that of the first gene of each cluster, cupA1 , cupB1 , and cupC1 , could clearly be identified. CS20 and other Class 1b fimbriae are assembled by the chaperone‐usher pathway (CUP), as are other fimbriae including Type 1 fimbriae and P‐fimbriae expressed by uropathogenic Escherichia coli (UPEC). termed cup for chaperone-usher pathways, which may be in- volved in the assembly of novel P. aeruginosa ﬁmbrial struc- tures that are radically dif ferent from the type IV pili (5, 38).

Extracellular appendages, such as flagella, type IV pili and Cup fimbriae are often involved in the initial attachment of bacteria to a surface. In P. aeruginosa, many of these surface structures are regulated by TCSs, and some systems regulate more than one type of appendage.

Geoffrey Pope Building, University of Exeter , Stocker Road, Exeter, EX4 4QD, UK 2020-07-21 2014-02-01 Until now, CUP chaperones have been classified into two families, FGS and FGL, based on the short and long length of the subunit-interacting loops between its F1 and G1 β-strands, respectively.

Pseudomonas aeruginosa exhibits swarming motility on 0.5 to 1% agar plates in the presence of specific carbon and nitrogen sources. We have found that PAO1 double mutants expressing neither flagella nor type IV pili ( fliC pilA ) display sliding motility under the same conditions.

Fimbria (female reproductive system), a fringe of tissue near the ovary leading to the fallopian tube. 2015-11-20 · aeruginosa CupA, CupB, CupC and CupD fimbriae have been shown to be involved in bacterial attachment and/or subsequent biofilm formation , , . Overexpression of each of the Cup gene clusters was shown to promote biofilm formation of P. aeruginosa. The large surface adhesin CdrA evidently also plays a role in P. The fimbriae (singular fimbria) is a fringe of tissue around the ostium of the Fallopian tube, in the direction of the ovary. Of all fimbriae, one fimbria is long enough to reach the ovary. It is called fimbria ovarica.

Cup fimbriae play an important role in cell-to-cell interactions in the early stage of biofilm formation (Wei and Ma, 2013). The composition and functions of EPSs in the P. aeruginosa biofilm were highlighted in several reviews (Flemming and Wingender, 2010; Moradali et al., 2017). The Motile–Sessile Lifestyle Switch The networks covered in depth regulate processes such as the switch between acute and chronic virulence (GacS network), the Cup fimbriae (Roc network and Rcs/Pvr network), the aminoarabinose modification of lipopolysaccharide (a network involving the PhoQP and PmrBA TCSs), twitching motility and virulence (a network formed from the Chp chemosensory pathway and the FimS/AlgR TCS), and biofilm formation (Wsp chemosensory pathway).

It is only about 65% heritable in West African by the chaperone-usher pathway (CUP), as are other fimbriae including Type 1 fimbriae and P-fimbriae expressed by uropathogenic Escherichia coli (UPEC). Certain sequence motifs are typical of CUP fimbriae, including alternating hydrophobic residues at the C-terminus of their pilins (Dodson et al., 1993, Nishiyama et al., 2005, Nishiyama et al., 2008). The networks covered in depth regulate processes such as the switch between acute and chronic virulence (GacS network), the Cup fimbriae (Roc network and Rcs/Pvr network), the aminoarabinose modification of lipopolysaccharide (a network involving the PhoQP and PmrBA TCSs), twitching motility and virulence (a network formed from the Chp chemosensory pathway and the FimS/AlgR TCS), and … Fig 8.

This enzyme hydrolyzes c-di-GMP in a two-step reaction, produc-ing as a final product two molecules of GMP (Fig. 1). Contrary

Overexpression of each of the Cup gene clusters was shown to promote biofilm formation of P. aeruginosa. The large surface adhesin CdrA evidently also plays a role in P. In an autoaggregative P. aeruginosa small colony variant (SCV) CupA fimbriae and the intracellular c-di-GMP concentration were found to be enhanced as compared with the clonal wild-type.
