Course description: The purpose of this semester of Microbiology is to familiarize the student with those concepts that are basic to viruses and prokaryotic and eukaryotic cells. Lecture is the foundation of the course. Laboratories will not always coincide with the lecture topics, as the laboratories are designed to give the student the basic laboratory techniques necessary to identify microorganisms. The student is responsible for assignments such as designated papers from the scientific literature that add to the lecture and lab material. In order to enhance appreciation of the course, the student is encouraged to seek out related materials that are available, such as scientific journals e.
Microbiology Lecture Materials
Cell, Nature, Scientific American , newspapers, magazines and television programs e. There are five basic topics in this course - the general principles for microbial the growth, evolution and classification; descriptions of different prokaryotic, eukaryotic and other lifeforms and how they utilize these principles; the natural ecology of microorganisms; the human use of microorganisms; and how microorganisms function in disease. Section one covers the first topic, the second topic is covered by sections two and three, and the final three are covered in section four. Some aspects of the last two topics are woven throuout the course. In order to understand how microorganisms can live, one must know what the parameters for their existance are. In order to get a feel for the diversity and scope of the microbial world, one must have a feel for what kinds of organisms exist, and to understand the ecology, uses and dangers of microorganisms, one should have a general knowledge of the different organisms to be encountered.
Microbiology Lecture Exam 1 Flashcards
All of these things are useful in life, in order to make informed decisions, and to go on to professional or graduate school. Learning activities will include reading and evaluation scientific papers, learning basic Microbiological techniques, identifying unknown bacteria, answering questions in lecture and writing scientific papers. Subjects learned previously in Themes of Biology e. Learning Goals Content Goals: When they have finished the course, students will have been introduced to a working knowledge of basic bacterial laboratory techniques, as well as to the foundations of Microbiology - the concepts of classification, evolution and growth of microorganisms, as well as a factual and laboratory knowledge of specific microorganism types - In addition, they should have developed an understanding of microbial ecology and of medical and practical uses for microorganisms, and how they relate to basic biological concepts.
Learn Microbiology Chapter 3
It is the intent of the course to provide an opportunity to learn the skills necessary to understand and get a feel for the basic ideas embodied within the various facts that they will encounter, and how those ideas are related. In general, they should understand how microorganisms survive where they do, how they are related, and how they interact with us. In the laboratory they should acquire basic bacteriological skills and should be able to successfully use them. Performance Goals: Students should acquire a good understanding of the concepts above. They should be able to show their mastery of them in oral and written form, in lecture, in the laboratory and in exams.
Dr. Carmen Elisabeth Rexach
They should be able to design experiments to identify microorganisms, interpret the data and communicate it. Student Assessment Microbiology is designed for Biology majors who want to expand their knowledge of the microscopic world, in general, or for use in professional or graduate school. Students need to be able to understand both the concepts presented as well as have a basic understanding of the factual nature of the course. They have to know what kinds of organisms are out there, in order to go on to higher learning, or to better understand the world. In order to achieve that goal, feedback will be given on questions asked in lecture and laboratory, exams and on the final laboratory report in as prompt fashion as possible so that the students will always understand how they stand. Learning Activities These will consist of lectures, laboratory demonstrations, laboratory work including independent investigation to identify unknown organisms , reading assigned scientific papers, writing a final laboratory report and answering those questions that are asked in lecture and laboratory.
Shared Flashcard Set
Hopefully this mix of learning styles will create a deeper appreciation of Microbiology. Initiative on the part of each individual student in asking pertinent questions and inviting conversation on related outside topics will be noted in the final grade. Selected articles; resource texts and reserve library materials may be assigned as required. Prescott, Harley and Klein text as assigned. Lectures cannot cover all that is in the text, and are designed to be complementary to, instead of a repetition of, the text. Exams will be on the lecture material and on those portions of the text directly relating to it. Assigned text readings are listed by chapter; a given lecture might not cover all the subjects in the chapter s listed.

By Aqsa A. July for Antimicrobial Pharmacology It helps me alot to memorize the things.. Thanku so much for such an amazing work.. July for Microbiology: Introduction The lecturer speaks clearly and is engaging. The material is presented quite well - in a logical manner. I feel the material could go in a bit more depth but perhaps later lectures will. I would probably give this series 5 stars, however, I'm currently studying for the USMLE, and I feel half or more of the review questions are extremely low-yield. For example, there are questions about which section of a plant does a specific fungus infect.

That's okay to test understanding of the lecture material presented, but I don't want to have that type of question included in my "Spaced Repetition" for memorization. It's a real waste of my limited time and brain space. Please ither remove the low-yield questions, or perhaps a better and faster option would be to add an option to turn off the "dumb" questions.

1. Introduction to Microbiology & Parasitology lecture
State three harmful effects and four beneficial effects associated with the activities of microorganisms. Define microbiota and microbiome. Briefly describe two different beneficial things the human microbiome does for the normal function of our body. State several diseases associated with a change in our "normal" microbiota. List and recognize a description of the each of the 5 basic groups of microbes. Microorganisms are the dominant life forms on earth, are found in almost every conceivable environment, and are essential to sustaining life on this planet. There are five basic groups of microorganisms: Bacteria are typically unicellular, microscopic, prokaryotic organisms that reproduce by binary fission.
BIOL 351 Fundamentals of Microbiology - Texas A&M University
Fungi yeasts and molds are typically unicellular, microscopic, eukaryotic fungi that reproduce asexually by budding. Molds are typically filamentous, eukaryotic fungi that reproduce by producing asexual reproductive spores. Viruses are typically submicroscopic, acellular infectious particles that can only replicate inside a living host cell. Protozoa are typically unicellular, microscopic, eukaryotic organisms that lack a cell wall. Algae are typically eukaryotic microorganisms that carry out photosynthesis. To get us started on our introduction of microorganisms we will go through the following Think-Pair-Share Questions.

The total number of bacteria in this tube is equal to: The number of people in Baltimore city. The number of people in Maryland. The number of people in North America. The number of people in the world. Briefly explain your answer. In what ways might microbes such as bacteria be harmful? In this course we will be looking at various fundamental concepts of microbiology, with particular emphasis on their relationships to human health. The overall goal is to better understand the total picture of infectious diseases in terms of host-infectious agent interaction. We will look at various groups of microbes and learn what they might do to establish infection and harm the body, we will look at the body to see the ways in which it defends itself against these microbes, and we will learn what can be done to help the body in its defense efforts. The Big Picture of Infectious Diseases One of the most important things in microbiology is learining the "Big Picture of Infectious Diseases," which is the biological basis of host parasite interaction.
Test Answers on Microbiology Lecture Exam #1
There are four interlocking parts to this big picture: The microbe's side of the story - why some microbes have more potential to be harmful: The overwhelming majority of microbes are harmless to humans and, in fact, many are beneficial, being key players in the recycling of nutrients in nature. We will look at the major groups of microbes, learn what they are composed of chemically and structurally, and see how how they carry out their metabolism and reproduce. We will learn of a variety of factors some microbes may possess that play a role in increasing their ability to cause disease.
Microbiology Lab Exam #1
Also we will learn how, through mutation, genetic recombination, and natural selection, microbes may adapt to resist our control attempts. The body's side of the story - ways in which the body is able to defend itself naturally against infectious disease agents: Here will learn about the phenomenal defenses the body has available to defend itself against infectious disease agents, as well as altered body cells such as cancer cells and infected cells. The body is able to do this through the innate immune system and the adaptive immune system. Innate immune defenses are those you are born with and include anatomical barriers, mechanical removal, cytokines, pattern-recognition receptors, phagocytosis, inflammation, the complement pathways, and fever. The adaptive immune defenses are those you develop throughout your life and include antibody production and cell-mediated immunity.
MICROBIOLOGY
Ways in which we can artificially help the body defend itself by removing the microbes or enhancing body defenses: We will learn how we can artificially help ourselves to avoid or reduce the risk of infection. Also we will learn ways in which we are able to artificially remove microbes from the body and its environment using agents such as antiseptics, disinfectants, physical agents such as heat and cold, antimicrobial chemotherapeutic chemicals, and antibiotics. Finally we will learn ways we are currently able to - or potentially in the future will be able to - improve or restore the body's immune responses through such techniques as immunization, adoptive immunotherapy, or immune modulation.
Micro 20 Lecture Notes, Spring
Relationship between the Human Microbiome and Human Health: The complex mutually beneficial symbiotic relationship between humans and their natural microbes is critical to good health. It is now recognized that the millions of genes associated with the normal flora or microbiota of the human body -especially in the intestinal tract - aid in the digestion of many foods, the regulation of multiple host metabolic pathways, and the regulation the body's immune defenses. Benefits of Microbial Activity Most people tend to think of microorganisms as harmful because of their roles in causing infectious diseases in humans and other animals, and agricultural loss as a result of infectious diseases of plants and the spoilage of food.
Biology exam 2 answers
The fact is, however, the vast majority of microorganisms are not harmful but rather beneficial. Without them there would be no life on earth. Therefore, we will start this course by looking at a few of the many benefits from microbial activity on this planet. Food production: Many food products employ microorganisms in their production. These include the microbial fermentation processes used to produce yogurt, buttermilk, cheeses, alcoholic beverages, leavened breads, sauerkraut, pickles, and kimchi.

Energy production and cleaning up the environment: Methane, or natural gas, is a product of methanogenic microorganisms. Many aquatic microbes capture light energy and store it in molecules used as food then used by other organisms. Animal wastes, domestic refuse, biomass, and grain can be converted to biofuels such as ethanol and methane by microorganisms. In addition, through a process called bioremediation , some pollutants such pesticides, solvents, and oil spills can be cleaned up with the aid of microbes.
