Dr. Mahmoud Elnaggar has been involved, throughout his career, in the study of Bovine/Ruminant Infectious Diseases, with an emphasis on Immunology, Microbiology, and Vaccine Development. Mahmoud started his career obtaining BVSc, MVSc and PhD in Veterinary Immunology from Alexandria University, Egypt, where he was successfully able to develop a cytokine flow cytometeric assay for quick and sensitive diagnosis of bovine tuberculosis. Mahmoud has then joined The Washington State University Monoclonal Antibody Center (WSUMAC), USA as a postdoctoral research associate during the period December 2014 – October 2019. In that role, Mahmoud made significant contributions to the development of monoclonal antibody reagents for ruminant species for use in the study of the immune responses to their infectious diseases. He was also heavily involved in developing platforms/assays to study the primary and recall responses and assess candidate vaccines to bovine pathogens, e.g. Mycobacterium avium subspecies paratuberculosis, Mycobacterium bovis and Theileria parva. During the period November 2019 – August 2020, Mahmoud joined The School of Biochemistry and Immunology at Trinity College Dublin, Ireland as a research fellow to advance the mission of Teagasc Bovine Immunology group to study the bovine T cells epigenomic changes associated with mycobacterial infections. In September 2020, Mahmoud returned back to Egypt to take up a Lecturer and then promoted to an Assistant Professor tenure in Veterinary Microbiology at Alexandria University. Currently, since September 2022, Mahmoud holds the position of an Assistant Professor in Veterinary Microbiology at The College of Applied and Health Sciences, A'Sharqiyah University, Sultanate of Oman. The long-term goal of Mahmoud’s career is to establish a multidisciplinary research program in Microbiology and Immunology of livestock infectious diseases, and use the derived information for the rational design of accurate diagnostics and efficacious vaccines for the prevention and control of livestock infectious diseases, including zoonotic infections, to support the global One Health Agenda.
