An elucidative study of the anti-biofilm effect of selenium nanoparticles (SeNPs) on selected biofilm producing pathogenic bacteria: A disintegrating effect of SeNPs on bacteria

Administration of probiotics affects Artemia franciscana metanauplii intestinal ultrastructure and offers resistance against a Photobacterium damselae ssp. piscicida induced oxidative stress response

“…The host organism, namely Artemia , responds in a different manner to each probiotic, with the increased antioxidant enzyme activity suggesting an immunostimulatory effect of probiotics. The production of different active substances by each probiotic, namely lysozyme [ 41 , 42 ], bacteriocins [39] and selenium nanoparticles [ 44 , 88 , 89 ] by B. subtilis, organic acids and bacteriocins including nisin by L. lactis [41] and organic acids, plantaricin, hydrogen peroxide, phenolic compounds, and surfactants by L. plantarum [90] might contribute to this variable effect among the probiotics employed. In fact, the addition of lysozyme significantly decreased the MDA content, and increased (SOD), activity, improving gur health in piglets [91] , plantaricin presented a synergistic action with lactic acid against A. hydrophila [92] and nisin was reported to boost growth performance and increases infection clearance rate in humans by upregulating innate and acquired immune responses [93] .…”

Antimicrobial hydrogels incorporating nanoselenium@reduced graphene oxide nanocomposites for biofilm inhibition

“…64,65 The small size of the nanocomposite and nSe allows them to penetrate the biofilm matrix, breaking down proteins and polysaccharides that stabilize it, ultimately eradicating the biofilm. 66,67…”

A review on synthesis and antibacterial potential of bio-selenium nanoparticles in the food industry

“…(B) Cell membrane damage and contents leakage ( Tareq et al, 2018 ; Sun et al, 2021 ; Prasathkumar et al, 2022 ). (C) Inhibiting the formation of biofilm ( Ramya et al, 2015 ; Shakibaie et al, 2015 ; Miglani and Tani-Ishii, 2021 ; Haddadian et al, 2022 ; Ullah et al, 2023 ). (D) Oxidative stress ( Cremonini et al, 2018 ; Alam et al, 2019 ; Prasathkumar et al, 2022 ).…”

“…NOSK effectively inhibited P. aeruginosa biofilm formation, and its large surface area, small size and spherical shape may be an important factor ( San Keskin et al, 2020 ). Bio-SeNPs produced by Bacillus subtilis BSN313 were strongly bound to bacterial surfaces and destroyed bacterial cells by disintegrating the membranes of P. aeruginosa , S. enterica serotype Typhimurium and S. aureus ( Ullah et al, 2023 ). In addition, Bio-SeNPs (2 μg/mL) generated by Bacillus sp.…”
