A master's thesis was discussed in the Qurna Education College, Department of Life Sciences at the University of Basra (isolation and identification of types of bacteria that form biofilms isolated from environmental samples and their relationship to the production of beta-lactamase enzymes) by researcher Sabah Rahim Hammadi and under the supervision of Assistant Professor Dr. / College of Science / University of Basra / Chair and Prof. Dr. Rashid Rahim Hatit / College of Nursing / Maysan University / Member and Prof. Dr. Adnan Badr / College of Education of Qurna / University of Basra / Member and Prof. Dr. Ismail Juma Abbas / Qurna Education College / Basra University / member and supervisor.

 The study examined the role of biofilms in protecting bacteria from environmental factors and increasing their resistance to antibiotics through their production of beta-lactamase enzymes and their resistance to various sterilizers and disinfectants.

 The study also showed that there is a relationship between the biofilms and the production of beta-lactamase enzymes as a result of their high resistance to beta-lactam flashes that are enzymatically resistant.

  In addition to what was shown by the results of the detection of beta-lactamase enzymes in terms of high rates, and the reason for this may be attributed to what is provided by the biofilms. The proximity of bacteria to each other may allow the enzyme resistance to be transferred genetically.
