Bacteria slingshot more on soft surfaces
Adaptive responses greatly improve the competitive capacities of bacteria in diverse environments. Here, we investigate whether bacteria can adapt to a microenvironment with distinctive softness by examining the type-IV pili (TFP)-mediated motility of Pseudomonas aeruginosa cells on brush-like surfaces that are grafted with a layer of thermally sensitive polymer chains, where the softness of th...

متن کاملDesigning surfaces that kill bacteria on contact.
Poly(4-vinyl-N-alkylpyridinium bromide) was covalently attached to glass slides to create a surface that kills airborne bacteria on contact. The antibacterial properties were assessed by spraying aqueous suspensions of bacterial cells on the surface, followed by air drying and counting the number of cells remaining viable (i.e., capable of growing colonies). Amino glass slides were acylated wit...
متن کاملSurvival of bacteria on metal surfaces.
Survivor curves were determined for Serratia marcescens, Sarcina lutea, Pasteurella tularensis, and P. pestis deposited from the airborne state onto metallic surfaces and subsequently stored at various humidities and temperatures. Cells of all species tested remained alive longest in a dry atmosphere, except that cells of S. marcescens survived best in a saturated atmosphere. Survival decreased...
متن کاملeffect of silver nanoparticles on common bacteria in hospital surfaces
conclusion silver nanoparticles had appropriate effects in all three types of dilutions and allowing for a more protracted contact time has given significantly better results. patients and methods we have selected nine patients' metal file covers and following sterilizing, we have infected them with one of these bacteria; staphylococcus aureus, pseudomonas aeruginosa and bacillus cereus. t...
