“…Impact of Environmental Factors on the Anti-staphylococcal Behavior of P. aeruginosa Although bacterial features play an important role in shaping inter-species interaction, environmental factors can have an even more decisive impact on them. Environmental conditions such as antibiotic and oxidant stresses are known to shape the CF ecosystem and promote a biofilm-based lifestyle of microorganisms within lungs (Feraco et al, 2016;Riquelme et al, 2020). Biofilm conditions reducing the competitive relationship between P. aeruginosa and S. aureus, the CF environment may favor a coexistence interaction between the two pathogens independently of P. aeruginosa's genetic adaptation.…”

Pseudomonas aeruginosa and Staphylococcus aureus are the two most prevalent bacteria species in the lungs of cystic fibrosis (CF) patients and are associated with poor clinical outcomes. Co-infection by the two species is a frequent situation that promotes their interaction. The ability of P. aeruginosa to outperform S. aureus has been widely described, and this competitive interaction was, for a long time, the only one considered. More recently, several studies have described that the two species are able to coexist. This change in relationship is linked to the evolution of bacterial strains in the lungs. This review attempts to decipher how bacterial adaptation to the CF environment can induce a change in the type of interaction and promote coexisting interaction between P. aeruginosa and S. aureus. The impact of coexistence on the establishment and maintenance of a chronic infection will also be presented, by considering the latest research on the subject.

“…As the bacteria start to grow they attach more firmly (that is, irreversible binding), and the increased number of microbes can trigger quorum sensing circuits that involve endogenous secreted signal molecules which, when accumulated to high enough local (that is, threshold) concentrations, are taken up activating profound regulatory changes (An & Friedman, ; de la Fuente‐Nuñez et al., ). A minimum contact time is required for irreversible binding between cells (Chmielewski & Frank, ), while the time frame for biofilm development in the food industry is usually relatively short, varying with respect to temperature, nutrient supply, and the presence of antimicrobial agents (Feraco, Blaha, Khan, Green, & Plotkin, ; Holah, ; Shi & Zhu, ).…”

Microorganisms can colonize and subsequently form biofilms on surfaces, which protect them from adverse conditions and make them more resistant than their planktonic free-living counterparts. This is a major concern in the food industry because the presence of biofilms has significant implications for microbial food contamination and, therefore, for the transmission of foodborne diseases. Adequate hygienic conditions and various preventive and control strategies have consequently been developed to ensure the provision of safe, good-quality food with an acceptable shelflife. This review focuses on the significance of biofilms in the food industry by describing the factors that favor their formation. The interconnected process among bacteria known as "quorum sensing," which plays a significant role in biofilm development, is also described. Furthermore, we discuss recent strategic methods to detect, quantify, and remove biofilms formed by pathogenic bacteria associated with food processing environments, focusing on the complexity of these microbial communities.

“…Biofilm formation consists of initial bacterial adherence to the surface, followed by multiplication and production of extracellular polymeric matrix, which cause cell aggregation (5). UPEC strains can produce a variety of adhesions for attachment to solid surfaces and biofilm formation.…”

Background/aim: Biofilm formation is a major determinant factor in the development of urinary tract infections (UTIs) by uropathogenic Escherichia coli (UPEC). Several adhesion factors are involved in attachment of bacterial cells to the urinary tract and biofilm development. Materials and methods: The possible relationship between different adhesion factor genes (AFGs) and biofilm formation among UPEC isolates was investigated. Prevalence of different AFGs including fimA, fimH, papAH, papC, papEF, sfa-S, foc/G, and bmaE and their association to biofilm formation were investigated. Phenotypic expression of type 1 and P fimbriae was also investigated. Results: Our results showed that 84% of UPEC were moderate to strong biofilm producers. Prevalence of the type 1 and P fimbriae associated genes (fimA, fimH, papEF, papC) as well as the F1C fimbriae gene (foc/G) did not show a difference among different biofilm-producing groups, while higher prevalence of papAH, bmaE (M fimbriae), and sfaS (S-fimbriae) was observed for the strains producing moderate to strong biofilms. Phenotypic expression of type 1 fimbriae was associated with biofilm formation, while no association was observed for P fimbriae. Conclusion: Different AFGs (especially M and S fimbria) and their expression levels affect the biofilm formation ability of UPEC.
