“…BapA (386 kDa) and SiiE (595 kDa) are the largest proteins of Salmonella and share the characteristics of having numerous bacterial Immunoglobulin-like domains. The genes encoding these two proteins are highly conserved among Salmonella serotypes ( Biswas et al, 2011 ; Suez et al, 2013 ). BapA has been shown to be involved in biofilm formation in S. Enteritidis.…”

Salmonella enterica species are Gram-negative bacteria, which are responsible for a wide range of food- and water-borne diseases in both humans and animals, thereby posing a major threat to public health. Recently, there has been an increasing number of reports, linking Salmonella contaminated raw vegetables and fruits with food poisoning. Many studies have shown that an essential feature of the pathogenicity of Salmonella is its capacity to cross a number of barriers requiring invasion of a large variety of cells and that the extent of internalization may be influenced by numerous factors. However, it is poorly understood how Salmonella successfully infects hosts as diversified as animals or plants. The aim of this review is to describe the different stages required for Salmonella interaction with its hosts: (i) attachment to host surfaces; (ii) entry processes; (iii) multiplication; (iv) suppression of host defense mechanisms; and to point out similarities and differences between animal and plant infections.

“…The ability of SiiE to bind Ca 2+ ions would confer a rigid rod-like habitus that is required for reach out beyond the LPS and initiates bacterial adhesion to polarized host cells (Wagner et al, 2011; Griessl et al, 2013). BapA is a 386 kDa protein allowing homotypic adhesion during Salmonella biofilm formation and is involved in pathogenesis, especially internalization and invasion of intestinal epithelium (Latasa et al, 2005; Jonas et al, 2007; Biswas et al, 2011; Suez et al, 2013). BapA is secreted extracellularly where it remains in loose association with the bacterial cell surface.…”

Proteinaceous determinants of surface colonization in bacteria: bacterial adhesion and biofilm formation from a protein secretion perspective

Bacterial colonization of biotic or abiotic surfaces results from two quite distinct physiological processes, namely bacterial adhesion and biofilm formation. Broadly speaking, a biofilm is defined as the sessile development of microbial cells. Biofilm formation arises following bacterial adhesion but not all single bacterial cells adhering reversibly or irreversibly engage inexorably into a sessile mode of growth. Among molecular determinants promoting bacterial colonization, surface proteins are the most functionally diverse active components. To be present on the bacterial cell surface, though, a protein must be secreted in the first place. Considering the close association of secreted proteins with their cognate secretion systems, the secretome (which refers both to the secretion systems and their protein substrates) is a key concept to apprehend the protein secretion and related physiological functions. The protein secretion systems are here considered in light of the differences in the cell-envelope architecture between diderm-LPS (archetypal Gram-negative), monoderm (archetypal Gram-positive) and diderm-mycolate (archetypal acid-fast) bacteria. Besides, their cognate secreted proteins engaged in the bacterial colonization process are regarded from single protein to supramolecular protein structure as well as the non-classical protein secretion. This state-of-the-art on the complement of the secretome (the secretion systems and their cognate effectors) involved in the surface colonization process in diderm-LPS and monoderm bacteria paves the way for future research directions in the field.

“…The expression of bapA is coordinated with that of genes encoding curli fimbriae and cellulose, through the action of csgD [26,39]. The bapA gene is also highly conserved in Salmonella [40]. Salmonella produces an O-antigen capsule coregulated with the fimbria-and cellulose-associated extracellular matrix.…”

Microbial Biofilms - Importance and Applications

Salmonella spp. may form biofilm, and bacteria in biofilm are more resistant to drug, chemical, physical and mechanical stresses, and host immune system. The progress on biofilm research will be helpful for the development of new tools and strategies to prevent biofilm-related disease and decontaminate biofilm-derived Salmonella in food production. In this review, we present a comprehensive overview of biofilm formation in Salmonella, included that the component of Salmonella biofilm, the detection methods for biofilm, the identification of biofilm-formation-associated genes, the regulation mechanism of biofilm formation, and virulence or resistance of Salmonella in biofilm.
