This presentation discusses various ways to treat diseases caused by microorganisms, including modern cures using antibiotics and traditional cures using plant-based remedies. It explains that antibiotics work by interfering with microbial cell walls, membranes, or chemical processes, and can be obtained from microorganisms or synthesized. However, antibiotics only work on bacterial infections, not viral diseases. The presentation warns that using drugs without medical advice can cause side effects and development of antibiotic-resistant microorganisms.
