Hospital surfaces are often contaminated with multidrug-resistant pathogenic bacteria that cause healthcare-associated infections and lead to increased mortality and morbidity. There is a need for new alternative antibacterial agents to overcome antibiotic resistance. Azadirachta indica and Simmondsia chinensis have been found to possess antibacterial activity and medicinal value.

- The study explores environmentally friendly methods for synthesizing copper oxide nanoparticles (CuO NPs) using plant extracts from Azadirachta indica and Simmondsia chinensis.
- CuO NPs were confirmed through color change and UV-visible spectroscopy, showing antibacterial properties against various clinical bacteria, including MRSA, with effective concentrations ranging from 62.5 to 125 µg/ml.
- The findings suggest CuO NPs as potential alternative antibiotics and support their application in the pharmaceutical and healthcare sectors globally.
Crop nutrition depends on zinc for enzymatic, oxidative, and metabolic processes. In the current study 20 different bacteria were isolated from five soil samples collected from different fields in Egypt. Bacterial isolates were screened for their ability to solubilize insoluble zinc oxide and zinc carbonate.
