2025-03-12
In continuation of the open scientific approach towards all sciences through which the goals and principles of sustainable development can be achieved at the Upper Euphrates Center for Sustainable Development Research at the University of Anbar, a panel discussion was held on the main hall of the center tagged: (Bacteria Around Us - Part One), on Tuesday, 11/3/2025, in which (Assistant Professor Dr. Muthanna Badie Farhan and Assistant Instructor Areej Hamad Hassan) lectured). The episode dealt with several axes, the first of which was the definition of microorganisms, which bacteria are one of the main groups in them, and the description of bacteria was identified in terms of shape, size and composition, in terms of shape, it is possible to be genera and types in different forms spherical and bacillus or twisted and be single or bilateral or grouped or take other forms has been clarified some qualities, for example, that the surface area of the bacterial cell to its weight is about two hundred thousand times greater than the surface area to the weight of a human being despite the fact that bacteria are microscopic organisms that are not visible to the naked eye. On the other hand, the lecturers explained that bacteria spread in the human body, whether on the surface of the skin or in the digestive system in the intestine and other organs in humans, and their spread is in large numbers as a natural flora and can contribute as an immune defence line against harmful bacteria that can enter the digestive system or fall on the skin, and at the same time this natural flora can become harmful bacteria, especially in cases of wounds or weak immunity in the human body. It was also addressed the ways in which bacteria maintain themselves and their numbers through reproduction in the manner of longitudinal fission transverse when the appropriate conditions are available for growth, division or the formation of blackboards in some of their bacillus genera, either in terms of movement it was clarified that the movement is either using flagella or be in the form of sliding or Brownian movement and that flagella can be present in the bacillus cell or either in the form of one terminal flagellum or in the form of a strand of flagella in one of the Cell poles or be present at the poles of the cell or be widespread in all areas of the body of the bacterial cell.
At the end of the seminar, the attendees praised the lecture and interacted with it through questions, interactive participations and discussion with the lecturers, and all questions and inquiries of the attendees were answered.
