A master’s thesis presented by Mohammed Saifuddin Saleh, titled “Evaluation of mucosal and Systemic Immune Antibodies Induced by Combined Attenuated Vaccines Against Newcastle Disease and Infectious Bronchitis in Broiler Chickens”

The College of Veterinary Medicine at the University of Mosul held a master’s thesis defense entitled “Evaluation of mucosal and Systemic Immune Antibodies Induced by Combined Attenuated Vaccines Against Newcastle Disease and Infectious Bronchitis in Broiler Chickens,” presented by graduate student Mohammed Saifuddin Saleh, specializing in Avian Diseases, on Tuesday, July 22, 2025.
The objective of the study was to evaluate the immunological and immunohistochemical responses to six commercially available attenuated and live combined vaccines targeting Newcastle disease and infectious bronchitis in poultry. The results demonstrated that several of the tested vaccines elicited acceptable and strong antibody titers against both viral pathogens. Histological expression of mucin secretion markers—MUC5AC and MUC5B—was observed at high to moderate levels in epithelial and goblet cells, depending on experimental group and vaccine type.
The examining committee comprised the following faculty members from the College of Veterinary Medicine, University of Mosul:
- Prof. Dr. Karam Hashim Yahya Al-Mallah – Chair
- Prof. Dr. Ammar Mahmoud Ahmed – Member
- Assist. Prof. Dr. Firas Mohammed Abed – Member
- Prof. Dr. Fanar Ablahad Ishaq – Member and Supervisor
Following a confident and scientifically grounded defense, the thesis was accepted.
Congratulations to the researcher, the supervisor, and the Department of Physiology, Biochemistry, and Pharmacology for this academic achievement. This discussion contributes to the realization of Sustainable Development Goal 4: Quality Education.
