Expression and Putative Roles in Attachment of Outer Membrane Proteins ofEscherichia coliO157 from Planktonic and Sessile Culture

Abstract: Many strains of Shiga toxigenic Escherichia coli (STEC), particularly the serotype O157:H7, are foodborne pathogens causing disease in many countries throughout the world. E. coli O157:H7 is able to attach and survive on various surfaces such as stainless steel (SS) found within the food processing environment. We examined the outer membrane protein (OMP) profiles of four E. coli O157 (three toxigenic O157:H7 and one nontoxigenic O157:HR) and one non-STEC strain (O1:H7), previously reported to have different a… Show more

“…In growth in a liquid matrix, cells are in a planktonic state, whereas when attached to a surface the cells should be in a sessile form. Growth in liquid versus growth on solid agar has been used in the literature as one method to examine the differences between these cells (24). In this study, reasons for deviation from expected first-order kinetics displayed by Salmonella were explored, including the type of method utilized for measurement of the thermal destruction rate and the possible influence of physiological state of growth on that rate.…”

“…OmpA can act as a porin for uptake of small molecules (Pautsch and Schulz, 1998; Arora et al, 2000), as a receptor for bacteriophage and colicin (Foulds and Barrett, 1973; Morona et al, 1984), and also as a structural protein to maintain the integrity of the outer membrane (Sonntag et al, 1978; Koebnik, 1995). It has also been reported to be an important target for immune response, a contributing factor to the pathogenicity of E. coli (Weiser and Gotschlich, 1991; Prasadarao et al, 1996; Belaaouaj et al, 2000; Wang, 2002; Godefroy et al, 2003; Jeannin et al, 2003), and a critical component of biofilm formation (Danese et al, 2000; Orme et al, 2006; Rivas et al, 2008). …”

“…Moreover, while there are many studies about attachment of bacteria to plant tissues and quartz (sand) in lab conditions, little is known about the genetic factors that drive the attachment of E. coli to representative stream particles under environmentally relevant conditions. Proteomic analysis has proven to be an effective method to explore the surface structures which play key roles in attachment (Otto et al, 2001; Orme et al, 2006; Rivas et al, 2008). …”

“…2001). OMPs BtuB and OmpW have been shown to be expressed in planktonic cultures of E. coli with the increased ability to attach to stainless steel, but not in planktonic cultures of low attaching E. coli to stainless steel (Rivas et al. 2008).…”

“…It is thought that a large number of factors (hydrophobicity, surface charge, outer membrane proteins (OMPs), surface structures, mode of growth and material properties) play a role in the attachment of bacterial cells to abiotic surfaces (Faille et al. 2002; Ukuku and Fett 2002; Rivas et al. 2008).…”
