An Introduction to the study of bacteria, viruses, fungi, and protozoa. Topics include History of Microbiology, Prokaryotic and Eukaryotic cells, Classification, Microscopy, Staining techniques, and Microbial growth and nutrition. Materials will include PowerPoint presentations, links to videos, and lecture notes. The course will take a month to complete. The course will be structured in such a way that there will be a progression from one concept to the next, although each lesson will be a stand alone. It will include laboratory aspects associated with Microbiology. Whether you are new to Microbiology, want to refresher course, or learn certain basic yet complex concepts, this course aims to deliver quality material which will make learning more engaging and Microbiology a more fascinating subject, specially as it relates to Medicine.

This lecture focuses on the debate over what constitutes life throughout history, mainly in terms of chemistry, that is, whether organic or inorganic compounds make up living organisms and on the difficulty in defining life. It describes the four basic processes of life found in living organisms. It ends by reviewing the cell theory which states that "all living things are composed of cells". .
In this part 2 of the study of Prokaryotes, we will cover the cytoplasmic membrane, which is the interface between the outer and inner environments of the cell, the cytoplasm, and the internal structures of the prokaryotes.
Part 1 of the study of Eukaryotes involves a description of the characteristics, classification, examples, structures, in general, of the Eukaryotes.
Part 2 of the study of Eukaryotes involves the description of the external structures, cytoplasmic membrane and cytoplasm of the Eukaryotes.
Part 3 of the study of Eukaryotes involves the description of the internal structures of the Eukaryotes, namely the membranous organelles.
The final part 4 of the study of Eukaryotes involves the description of the non-membranous organelles that are part of the internal structures of the Eukaryotes.
This last lecture, in the section of Characteristics of Cells and Viruses, describes the characteristics of viruses, that distinguish them from cells, the structure and shapes of viruses, and finally the Baltimore classification of viruses.
This first lecture in the section of Microscopy introduces the comparative sizes and covers the topics of size measurement system, size comparisons among the different organisms and size comparisons relative to the 3 modes of observation, and the most common size ranges of microbial agents.
Part 1 of the lecture in Light Microscopy covers the use, definition and parts of the light microscope. It also includes description of image formation and light pathway.
This part 2 of the lecture in Light Microscopy describes the main concepts related to microscopy, such as magnification, resolution power and index of refraction, as well as other configurations, apart from light microscopy, such as phase-contrast, dark-field, and fluorescent microscopy.
Please note: This video does not start until 5:15 -5:17 timepoint.
Dr. Sunita Seemanapalli has over 10 years of experience in biomedical research, particularly in field of Microbiology. She has a Medical Degree from the Federal University of Paraiba, Brazil. In order to better understand the basic mechanism of disease processes, she pursued graduate studies in the US. She earned an M.S. from Southern University, Baton Rouge, LA. Her Master's thesis focused on the levels of p53, a tumor suppressor protein in Human Cytomegalovirus-infected cells. She earned her Ph.D. from Louisiana State University, Baton Rouge, LA. Her Ph.D. dissertation focused on the role of Outer Surface Protein C in the pathogenesis of Borrelia burgdorferi, the agent of Lyme disease. In March 2011, Dr. Seemanapalli completed one year of post-doctoral research at Texas A&M, College Station, TX, where she developed mutant and complementation strains of Borrelia burgdorferi expressing virulent genes.
Dr. Seemanapalli worked at Pennington Biomedical Research Center in the Department of Human Genomics for 5 years. She also worked at the Hansen's Disease Center for about a year in research related to multi-drug resistant Mycobacterium tuberculosis.
In reference to her teaching experience, Dr. Seemanapalli taught General Biology Laboratory courses as a Teaching Assistant at Southern University and as an Adjunct Instructor at the Baton Rouge Community College for one and a half years.In the Fall of 2011, Dr. Seemanapalli taught Microbiology lecture and lab course at Blinn College, a Community College located in Bryan, TX.
Dr. Seemanapalli won several awards for excellent powerpoint presentations at local, regional and national scientific meetings. She has a first author and several co-author papers published in several peer-reviewed journals, including in the Journal of Immunology. Her expertise is in the areas of Microbiology, Molecular Biology and Immunology. She is passionate about teaching Microbiology in an engaging and interest-captivating manner.
