Summary: The natural compound EPS-cn2 from Lactobacillus casei NA-2 inhibits biofilm formation by Escherichia coli O157:H7. EPS-cn2 decreases bacterial adhesion and alters surface properties. RNA sequencing reveals down-regulation of adhesion-related genes and up-regulation of chemotaxis and motility-related genes.

Summary: Bacteria within biofilms exposed to sub-MIC concentrations of antibiotics can develop antibiotic resistance. This study shows that sub-MIC levels of aminoglycosides induce the SOS response in E. coli carrying the qnrD gene, leading to genetic rearrangements and increased biofilm formation. The presence of the qnrD-plasmid promotes biofilm production and the acquisition and spread of resistance determinants for other antibiotics.

Summary: In order to address the environmental impact of the textile industry, self-repairing textile composites have been developed by integrating Escherichia coli biofilms into conventional textiles. The curli fibers in the biofilm have demonstrated the ability to self-assemble and self-heal. Through simple and scalable methods, such as adsorption, doctor blading, and vacuum filtration, the biofilms were successfully integrated into the textiles.

Summary: This study investigated the association between biofilm formation and antibiotic resistance in extensively drug-resistant Escherichia coli isolates. The results showed that stronger biofilm formation was correlated with larger proportions of extensively drug-resistant isolates. These findings provide novel insights for the prevention and treatment of E. coli-related infections.

Summary: This study evaluated the antibiotic resistance/susceptibility profiles and biofilm-forming capacities of 81 Escherichia coli isolates from pediatric individuals in China, revealing an association between biofilm formation and resistance to several antibiotics for extensively drug-resistant strains. This finding provides novel insights for the prevention and treatment against E. coli-related infections.

Summary: This study used atomic force microscopy to investigate the impact of phage T4 on the nanotopography and biomechanics of biofilm-forming E. coli cells. The results revealed that anchored cells undergoing biofilm formation experience a more gradual lysis with distinct nanoscale lesions, unlike the explosive lysis seen in planktonic cells. Furthermore, envelope rigidity and cell elasticity decrease significantly following T4 infection, indicating potential changes in the nanostructure of infected cells.

Summary: Biofilms are a crucial mode of growth for bacteria, but how antibiotic resistance emerges and is selected in biofilms is poorly understood. This study developed and validated a microfluidic chip (Brimor) for studying the dynamics of antibiotic-resistant bacteria in biofilms. The chip was found to be easy to use and a relevant model for studying the selection of antibiotic resistance in bacterial biofilms, providing valuable insights into this area of research.

Summary: The study revealed that sub-minimum inhibitory concentrations of amoxicillin significantly impact the growth, motility, and biofilm formation of Escherichia coli, while enhancing its cell adhesion capabilities. This could potentially contribute to the propagation of antibiotic resistance by commensal bacteria.

Summary: Endometritis is a common cause of infertility in mares, often caused by bacteria such as E. coli and beta-haemolytic streptococci. This study aimed to detect the presence and localization of E. coli bacteria in equine endometrial biopsies using a chromogenic RNAscope method. However, no evidence of bacterial invasion was found, regardless of the inflammatory status or previous bacterial culture results. Further research is needed to investigate potential localized infections or biofilm coverings that may have led to undetected bacterial presence.

Summary: Bacterial adhesion is influenced by bacterial transport and the interactions between bacterial adhesins and surface receptors. Gravity sedimentation causes bacteria to concentrate on lower surfaces, and initial bacterial attachment may be inhibited by shear due to mass transport effects. A conceptual framework and theory are provided to predict the impact of sedimentation on adhesion between and within adhesive regions in flow, and to normalize bacterial binding level under experimental set-ups.
