addresses the global threat posed by infectious and emerging diseases to human and animal health and biodiversity. It focuses on a study in Egypt on avian influenza viruses, paramyxoviruses, and coronaviruses circulating among wild birds and bats. It demonstrates that these organisms are natural reservoirs of highly pathogenic viruses that can be transmitted to humans. It highlights the significant role of wild birds in the spread and evolution of avian influenza viruses due to their seasonal migration. Genetic analyses have also shown that influenza viruses in poultry are closely related to those in wild birds, proving their transmission between them. H5N8 strains have also been isolated in Egypt and their association with local birds has been determined. An evolutionary relationship has also been established between paramyxovirus strains in poultry and wild birds. The book concludes that wildlife represents an important link in virus transmission, calling for further monitoring and research.

Background Foodborne infections are a serious concern to public health, especially because they can create biofilms that increase their resistance to standard antibiotic therapies. Aim the study lies in the development and application of ecofriendly, biogenic silver nanoparticles (Ag-NPs) synthesized using a bacterial strain, Klebsiella variicola, for inhibiting growth of foodborne pathogens and their biofilms. Methods In the current study, the endophytic bacterial strain Klebsiella variicola was used to create ecofriendly silver nanoparticles (Ag-NPs), which were then examined using TEM, XRD, ATR-FTIR, and UV-VIS spectroscopy. The resultant Ag-NPs, which ranged in size from 5-15 nm, showed a distinct spherical crystalline structure. Results The antimicrobial performance of biogenic Ag-NPs was evaluated against four foodborne pathogens (Escherichia coli, Bacillus cereus, Pseudomonas aeruginosa
