The Department of Biology at the College of Science, University of Mosul, discussed a PhD dissertation on Thursday, February 12, 2026, entitled:<\/p>\n

\u201cIsolation and Identification of Surface Proteins of Streptococcus<\/em> spp. Isolated from Different Clinical Sources and Studying Their Relation with Immunological Parameters\u201d<\/strong><\/p>\n

submitted by PhD candidate Ahmed Khalid Hamdoon<\/strong> from the Department of Biology.<\/p>\n

The dissertation focused on several key research areas, including:<\/p>\n

    \n
  1. The isolation of Streptococcus<\/em> species for the first time in Mosul, with particular emphasis on Streptococcus sobrinus<\/em> and its role in gingival and dental root infections.<\/li>\n
  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.<\/li>\n
  3. The investigation of immunological responses involving cytokines and interleukins in lymphocytes using ELISA assays for Interleukin-1\u03b2 and Interleukin-6.<\/li>\n
  4. The exploration of the immunological relationship between Streptococcus sobrinus<\/em> and Helicobacter pylori<\/em> through the NIA technique for the first time, involving participants aged between 20 and 60 years from both genders.<\/li>\n<\/ol>\n

    The examination committee was chaired by:<\/p>\n
