“…Zinc oxide nanoparticles (ZnO-NPs) have been reported as an antimicrobial agent against both pathogenic and spoilage microorganisms (Ann et al, 2014;Duffy et al, 2018;Pasquet et al, 2014;Raghunath and Perumal, 2017;Raghupathi et al, 2011;Savi et al, 2013;Vargas-Reus et al, 2012;Xie et al, 2011). ZnO-NPs application as antimicrobial agent stands out in comparison to other metallic nanoparticles (Jones et al, 2008).…”

ZnO-NPs can be obtained through various methods, resulting in nanoparticles with different size and morphology, which directly influences their antimicrobial potential. The objective of this work was to evaluate the antibacterial activity of ZnO-NPs obtained by a solochemical process against important human foodborne pathogens: Staphylococcus aureus, Salmonella Typhimurium, Bacillus cereus and Pseudomonas aeruginosa. ZnO-NPs were identified as nanorods with the length between 90.1 and 100 nm (10.5 % frequency), the diameter between 80.1 and 90 nm (21 % frequency), and wurtzite type crystalline structure. The Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) were equal to 0.05 mg mL-1 and 0.5 mg mL-1 for S. aureus and S. Typhimurium, respectively, lower than previous results related in the literature. ZnO-NPs produced by solochemical method had a superior antibacterial activity. For instance, they can be incorporated in packaging materials for increasing microbial safety and food shelf-life by inhibiting bacterial growth.

“…In addition, its deficiency has been linked to impaired wound healing process (Lansdown et al, 2007;Kogan et al, 2017). Zinc oxide possesses antimicrobial activity (Ann et al, 2014;Pasquet et al, 2015). Recently, the involvement of nanoparticles in wound treatment protocols is increased.…”

This study was aimed to evaluate the wound healing activity of both green and chemical Zinc oxide Nanoparticles in equine. Ten animals (nine donkeys and one horse) suffered from traumatized infected or non-infected wounds were used in this study. The visible signs of wound infection were evaluated in six cases, while the other four cases were admitted with fresh recent wounds. Animals were topically treated once a day in and day out and monitored for three weeks. It was observed that, the macroscopic wound contraction percents in animals treated with green Zinc oxide Nanoparticles gel in 1st, 2nd and 3rd weeks were 45%, 76%, and 93.6% respectively. While, those which treated with chemical Zinc oxide Nanoparticles gel were 40.4%, 67.2%, and 90.6% respectively. The study revealed that, green Zinc oxide Nanoparticles gel accelerated the wound healing and cleared the wound infection faster when compared to chemical Zinc oxide Nanoparticles gel. It was concluded that, topical green Zinc oxide Nanoparticles gel can significantly accelerate the process of wound healing and clear the wound infections in wounded equine from clinical field cases.

“…There are also some similar reports on the biological influences of oxidant stress caused by environmental conditions. Staphylococcus aureus, Pseudomonas aeruginosa and Streptococcus pyogenes could resist the toxicological effect of ZnO in the presence of catalase (CAT) (Ann et al 2014). The antioxidant defense system including SOD helps two green microalgae to resist the tannery effluent (Ajayan and Selvaraju 2012), Zn of certain concentration could improve the metabolisms and oxidation-reduction enzyme activities of microbialcommunities in the compost (Zhang et al 2012b).…”

Binary pollution of both heavy metals and antibiotics has received increasing attentions for their joint effects of eco-toxicity and health hazards. To reveal the effects of mixtures of different pollutants on bacterial antioxidant response system, Pseudomonas fluorescens ZY2, a new strain isolated from swine wastewater, was chosen to determinate growth (bacterial density OD600), reactive oxygen species (ROS) concentration, protein concentration and superoxide dismutase (SOD) activity under exposure treatments of Zn, Cefradine or Zn + Cefradine. Bacterial densities of all the treatment groups increased significantly over the incubation time, but those containing pollutant addition were slightly lower than the control at different times of incubation. Both ROS concentration and SOD activity increased first and then decreased (p < 0.01) over time, which was opposite to the protein concentrations (p < 0.01), showing a much significant increase by Cefradine alone. With Zn concentration increasing from 40 to 160 mg/L, the intracellular SOD activity increased as a response to the improvement of ROS (p < 0.05), while the balance between ROS and SOD was broken down due to the disproportionate change of total SOD activity and ROS concentration, the bacterial densities therefore decreased for the weak resistance. With the combined treatment of Zn (200 mg/L) and Cefradine (1 mg/L), though the toxicity of Zn caused a much significant increase of ROS, the bacterial resistance was further improved showing a more significant increase of total SOD activity and the bacterial densities therefore increased bacterial growth. Zn concentration also affected the protein synthesis. Either single or binary stress induced the bacterial resistance by regulating SOD activity to eliminate ROS. All results of the bacterial oxidant stress, SOD response and protein synthesis in the combined treatment groups were more complicated than those in single treatment groups, which depended on the properties of the single treatment as well as the interaction between the two treatments upon bacterial activity. For P. fluorescens ZY2, the mediation of SOD activity to eliminate ROS in response to the combined exposure to Zn and Cefradine was first revealed as one of the co-resistance mechanisms, which is informative to further understanding the risk of antibiotics resistant bacteria to human and environmental health more accurately.
