On Tuesday, February 17, 2026, the Faculty of Science at the University of Tabuk, represented by the Department of Biology, organized a scientific event entitled “Microbial Biodiversity” in the lobby of the Faculty of Pharmacy. The event was held as part of the department’s community responsibility initiatives, aiming to raise awareness about the importance of microorganisms and highlight their vital roles in supporting ecosystems, promoting human health and driving scientific innovation.
The event was inaugurated in the presence of the Head of the Department of Biology, Dr. Ra'fat Al-Qurashi; the Vice Dean of the Faculty of Science for Academic Affairs, Dr. Nasser Al-Omrani; the Vice Dean of the Faculty of Science for Female Students, Dr. Abeer Al-Mutairi; the Supervisor of the Department of Biology for Female Students, Dr. Siham Al-Balawi; the Chair of the Scientific Activities and Community Service Committee, Dr. Fawzia Al-Balawi; along with several faculty members and students.
The exhibition featured a variety of specialized scientific displays:
Microbial Control Corner: This section explored strategies for controlling pathogenic microorganisms, insects and plant diseases. It emphasized the role of natural plants and fungal-derived antibiotics in combating harmful bacteria, supported by scientific posters showcasing the latest applications in this field.
Bioluminescent Bacteria Corner: Attendees learned about the mechanism of bioluminescence based on the luciferase enzyme and were introduced to the phenomenon of “milky seas,” along with examples of well-known luminous bacterial species. The display included microscopic slides and culture plates with creative bacterial illustrations, allowing participants to directly observe microbial characteristics.
Predatory Bacteria Model: A dedicated section presented a model explaining the predation mechanism of Bdellovibrio bacteriovorus, portraying it as a “bacterial predator” and a “living antibiotic,” and highlighting its promising research potential in combating antibiotic resistance.
Gut Microbiome Corner: This section discussed the role of the microbiome in influencing neurological conditions through the gut–brain axis, stressing the importance of microbial balance for overall health.
Beneficial Bacteria Corner: The display showcased the health benefits of beneficial bacteria, foods rich in probiotics and the negative impact of irrational antibiotic use on microbial balance. It also highlighted the role of certain microbes in protecting coral reefs, maintaining ecological balance and contributing to climate change mitigation.
Health Awareness Sections: These included educational posters about bacterial respiratory diseases and an awareness corner about the parasite Giardia lamblia, covering its modes of transmission and prevention strategies.
“Microbes in Our Lives” Section: This segment explored the diverse roles of microorganisms in the environment, industry and food production, demonstrating their profound impact on daily life.
In an advanced applied segment, a scientific poster addressed the importance of the microbiome in forensic medicine. It explained how each individual’s unique bacterial “fingerprint” can assist in crime detection, personal identification and estimation of time of death. The presentation highlighted the role of metagenomic analysis and environmental factors in tracking microbial community changes during decomposition, thereby enhancing the accuracy of criminal investigations.
The event witnessed enthusiastic engagement and fruitful scientific discussions, reflecting attendees’ growing interest in the microbial world and its modern applications. The dynamic scientific atmosphere successfully combined theoretical knowledge with practical experience.
The event concluded with expressions of gratitude and appreciation to all participants and organizers for their outstanding efforts. Its success reflects the Department of Biology’s strong commitment to knowledge dissemination, community service, environmental sustainability and scientific innovation.
