The Department of Biology at the College of Science, University of Mosul, discussed a PhD dissertation on Thursday, February 12, 2026, entitled:

“Isolation and Identification of Surface Proteins of Streptococcus spp. Isolated from Different Clinical Sources and Studying Their Relation with Immunological Parameters”

submitted by PhD candidate Ahmed Khalid Hamdoon from the Department of Biology.

The dissertation focused on several key research areas, including:

1. The isolation of Streptococcus species for the first time in Mosul, with particular emphasis on Streptococcus sobrinus and its role in gingival and dental root infections.
2. The isolation and characterization of bacterial surface proteins using advanced analytical techniques, including Ion Exchange Chromatography (IEC), Gel Filtration Chromatography (GFC), and SDS-PAGE.
3. The investigation of immunological responses involving cytokines and interleukins in lymphocytes using ELISA assays for Interleukin-1β and Interleukin-6.
4. The exploration of the immunological relationship between Streptococcus sobrinus and Helicobacter pylori through the NIA technique for the first time, involving participants aged between 20 and 60 years from both genders.

The examination committee was chaired by:

• Prof. Mahmoud Abduljabbar Hussein

and included:

• Prof. Fatima Aboudi Ali
• Prof. Anmar Ahmed Dawood
• Assist. Prof. Rogan Ghanim Mohammed
• Assist. Prof. Mohammed Abdullah Mahmoud

with supervision and committee membership by:

• Prof. Hiyam Adel Ibrahim
• Assist. Prof. Aws Ibrahim Suleiman

During the session, the Dean of the College of Science, Prof. Hiyam Adel Ibrahim, presented a Letter of Appreciation to Prof. Fatima Aboudi Ali from Hawler Medical University, Erbil, in recognition of her valuable scientific contributions and constructive observations, which enriched the academic quality of the dissertation.

At the conclusion of the defense, the committee commended the dissertation for its high scientific standard and emphasized the significance of its findings in medical research and sustainable healthcare. The study offers promising practical applications that could contribute to advancing the healthcare sector.

This dissertation aligns with several United Nations Sustainable Development Goals (SDGs), particularly SDG 3 (Good Health and Well-being) through enhancing understanding of immune mechanisms associated with bacterial infections and improving opportunities for early diagnosis and treatment. It also supports SDG 9 (Industry, Innovation and Infrastructure) by employing modern biotechnological techniques in scientific research, and SDG 17 (Partnerships for the Goals) through academic collaboration among universities and scientific institutions.

We extend our sincere congratulations to our student and wish him continued success and excellence in his academic and professional journey.
