Escherichia coliadhesion, biofilm development and antibiotic susceptibility on biomedical materials

Abstract

27The aim of this work was to test materials typically used in the construction of medical

Myricetin protects Galleria mellonella against Staphylococcus aureus infection and inhibits multiple virulence factors

“…7). Corroborating these findings, other reports in literature show that material surfaces presenting a hydrophilic character substantially impair bacterial attachment to abiotic surfaces 43–45 . Although the spin-coating technique is one of the most common methods for applying uniform thin films to substrates, further studies are needed to evaluate a possible grafted version of this polyphenol.…”

Antimicrobial activity of multifaceted lactoferrin or graphene oxide functionalized silver nanocomposites biosynthesized using mushroom waste and chitosan

“…It is well documented that antibiotics can affect bacteria in ways other than the expected bactericidal action, including induction of morphological changes. 68,69 Morphological dissimilarity of AgNPs was also reported by Patil et al 70…”

Biofilm formation behaviour of marine filamentous cyanobacterial strains in controlled hydrodynamic conditions

“…Since the contact angle of water on glass was θ w = 48.55 ± 2.41 and in perspex θ w = 73.05 ± 3.42, perspex is relatively hydrophobic compared to glass, exhibiting a lower wettability. Although lower values for glass have been reported, some studies performed with glass surfaces, also showed values in the 40° range (Sener et al ., ; Thukkaram et al ., ; Gomes et al ., ; Moreira et al ., ). This slightly increased value may be related to the composition of this specific glass although other glass surfaces that can be used to construct submerged devices (underwater cameras, measuring devices or sensors) can have different hydrophobicities.…”

“…Surface analysis was performed by measuring the contact angles with water ( θ w ) as reference liquid. This determination was performed in three independent experiments at 25°C ± 2°C, by the sessile drop method using a contact angle meter (Dataphysics OCA 15 Plus, Filderstadt, Germany), as described in Gomes et al ., . On each experiment, at least 25 determinations for each material were made.…”
