Summary: Zinc oxide (ZnO) nanoparticles prepared with the assistance of a biomass extract from Halimeda opuntia showed antibacterial properties against Vibrio harveyi, a pathogen in aquaculture. The nanoparticles had a crystalline hexagonal wurtzite structure with a size of 33 nm. The chemical valence of zinc on the surface of the nanoparticles was determined to be +2. The morphology and elemental composition of the particles were studied using scanning electron microscopy equipped with energy-dispersive X-ray spectroscopy. The study also identified and analyzed the major bioactive compounds in the biomass extract using gas chromatography-mass spectrometry. The results demonstrated the potential of ZnO nanoparticles as an antibacterial agent.

Summary: This study describes a concise and eco-friendly method to synthesize nano zinc oxide (nZnO) particles using raw Garcinia Cambogia fruit pulp extract. The synthesized nZnO exhibits remarkable crystallinity, purity, and a hexagonal wurtzite structure. The spherical nZnO particles with an average diameter of 32.8 nm are observed through scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The UV-Visible diffuse reflectance spectroscopy (UV-Vis DRS) results show that the optical bandgap of nZnO is 3.24 eV. Moreover, nZnO demonstrates excellent photocatalytic activity for dye degradation and substantial bactericidal effects against pathogenic bacteria.

Summary: The present study aimed to investigate the prevalence of intestinal parasitic worms and protozoa in different breeds of pigeons in Taif governorate, as well as their association with intestinal pathological changes. A total of 212 pigeons from four different breeds were examined, and clinical symptoms such as emaciation, dullness, abnormal droppings, and diarrhea were observed in 96 pigeons. Pakistani breed had the highest prevalence of helminthic infection (54.7%), followed by the local breed (26.4%), French breed (18.9%), and Harami breed (11.3%). Multiple species of cestodes, nematodes, and protozoa were identified. Histopathological findings in the intestine revealed necrosis, epithelial desquamation, villi atrophy, and inflammatory cell infiltration, particularly eosinophils. The study highlights the importance of future research to prevent avian parasitic transmission to livestock and humans in Taif governorate.
