This comprehensive review explores the emergence of titanium dioxide nanoparticles (TiO-NPs) as versatile nanomaterials, particularly exploring their biogenic synthesis methods through different biological entities such as plants, bacteria, fungi, viruses, and algae. These biological entities provide eco-friendly, cost-effective, biocompatible, and rapid methods for TiO-NP synthesis to overcome the disadvantages of traditional approaches. TiO-NPs have distinctive properties, including high surface area, stability, UV protection, and photocatalytic activity, which enable diverse applications.

The endophytic actinobacteria associated with Artemisia herba-alba (synonym: Seriphidium herba-alba) are highly diverse. This study aimed to illustrate the extent of their differences from the free-living actinobacteria in the surrounding environment. A selection of eighteen actinobacteria inhabiting A.

This study aimed to evaluate the prevalence, multidrug-resistance traits, PCR-detection of virulence, and antibiotic-resistance genes of E. coli isolated from secondary infections following FMD-outbreak in cattle. A total of 160 random samples were gathered from private dairy farms in Damietta Province, Egypt.

Motile Aeromonas septicemia is a common bacterial disease that affects and causes tremendous economic losses globally. In order to investigate the prevalence, molecular typing, antibiogram and the biodiversity of complex, a total of 250 tilapia () were collected randomly from 10 private tilapia farms (25 fish/farm) at El-Sharkia Governorate, Egypt. The collected fish were subjected to clinical and bacteriological examinations.

Article Synopsis
  • The study explores the diversity of endophytic actinomycetes in ten Compositae plant species from South Sinai, identifying 131 isolates across 14 genera, including rare ones like Microtetraspora and Intrasporangium.
  • Microscopic and chemotaxonomic analyses revealed varying levels of endophytic diversity, with plants grouping into high, moderate, and low diversity categories.
  • The endophytes exhibited significant functional diversity, particularly in stress tolerance and plant growth promotion traits, highlighting their potential benefits for host plants and suggesting valuable applications for actinobacteria in agriculture.
