Introduction to Microbiology is an undergraduate course exploring the study of microscopic organisms, including bacteria, viruses, fungi, protozoa, and algae, and their interactions with the environment and other organisms. Students will embark on a comprehensive journey into the realm of microbiology, delving into the fundamental principles that govern microbial life. The course begins by examining the historical foundations of microbiology, tracing the milestones in our understanding of microbes and their impact on human society. Students explore the structural and functional diversity of microorganisms; learn about the cellular architecture of bacteria, archaea, and eukaryotic microbes, and how their unique features enable them to thrive in diverse environments. Topics include microbial metabolism, growth, and reproduction, as well as the mechanisms of microbial genetics and gene regulation. By the end of the course, students will have gained a solid foundation in microbiology and its relevance to society, preparing them for further studies or careers in related fields.
