Researcher | Animal Health Research Institute | Egypt
Dr. Nagwa Ibrahim Saad Abu-Zahra is a distinguished researcher at the Animal Health Research Institute (AHRI), Agriculture Research Center, Giza, Egypt, specializing in fish immunology, aquatic toxicology, and aquaculture health management. She earned her academic degrees in veterinary and animal sciences, building a strong foundation for her career in aquatic animal health. Her research primarily explores the impacts of pharmaceuticals, natural compounds, and environmental stressors on the physiology, immunity, and pathology of Nile tilapia (Oreochromis niloticus) and other aquatic species. Dr. Abu-Zahra has authored more than ten publications indexed in the Web of Science, including high-impact studies such as Impacts of florfenicol on immunity, antioxidant activity, and histopathology of Oreochromis niloticus: a potential protective effect of dietary spirulina platensis (Veterinary Research Communications, 2024) and Azolla pinnata mitigates pendimethalin induced immunotoxicity and oxidative stress in Oreochromis niloticus (Scientific Reports, 2025). Her work has been cited widely, contributing to an H-index of 3, with research spanning nutritional immunomodulation, nanotechnology applications, and mitigation of aquatic pollutants. In recognition of her expertise, Dr. Abu-Zahra has served as a peer reviewer for more than 20 manuscripts across leading journals such as Aquaculture International (Springer Nature), Scientific Reports (Nature Publishing Group), and Journal of Applied Aquaculture (Taylor & Francis). She has also contributed reviews for regional journals, highlighting her commitment to advancing global and local aquaculture research. With a growing academic footprint and dedication to sustainable aquaculture practices, Dr. Abu-Zahra continues to play a pivotal role in bridging veterinary science and aquatic environmental health. He has authored 8 publications indexed in Web of Science, accumulating over 35 citations with an H-index of 3.
