In this chapter, you'll learn the answers to questions including:
- How did Louis Pasteur contribute to the germ theory of disease?
- How do antibiotics and vaccines work?
- How are eukaryotic and prokaryotic cells different or the same?
- What are archaea and bacteria?
- What are some species of cyanobacteria?
- What are the unique characteristics of algae, fungi and protozoa?
1. The Germ Theory of Disease: Definition & Louis Pasteur
In this lesson, we will look at one of the most influential experiments in the field of microbiology. We will learn how Louis Pasteur disproved the theory of spontaneous generation which helped lead to the development of the germ theory of disease.
2. Antibiotics and Vaccines
Do you know why children must get regularly vaccinated? Have you ever wondered how an antibiotic works and why they are so widely prescribed? If so, this lesson will help you to understand how changes in medicine have almost eliminated several deadly diseases and added decades to the average person's lifespan.
3. Eukaryotic and Prokaryotic Cells: Similarities and Differences
In this lesson, we discuss the similarities and differences between the eukaryotic cells of your body and prokaryotic cells such as bacteria. Eukaryotes organize different functions within specialized membrane-bound compartments called organelles. These structures do not exist in prokaryotes.
4. Archaea: Definition, Characteristics & Examples
There is an entire domain of life that is made up of single-celled organisms without nuclei. We're not referring to the Bacteria domain, however. In this lesson, we will examine the main characteristics of the least commonly known domain, the Archaea.
5. What is Bacteria? - Definition, Characteristics & Examples
This lesson will introduce the Bacteria, a large and diverse group of microorganisms. We will examine several key characteristics, as well as a few commonly known examples of bacterial species.
6. Cyanobacteria: Definition, Characteristics & Species
Cyanobacteria are a phylum of Bacteria that produce oxygen during photosynthesis. This lesson will examine cyanobacteria and the role they played in establishing our oxygen-rich atmosphere.
7. What are Protozoa? - Definition, Characteristics & Examples
Taxonomy is the realm of science that attempts to group similar organisms together, which is not always an easy task. In this lesson, we will examine the protozoa, a diverse group of organisms that didn't really fit anywhere else.
8. What is Algae? - Definition, Characteristics & Examples
Plants are not the only organisms capable of carrying out photosynthesis. In this lesson we will look at algae and how an algal species can be differentiated from other organisms and microbes.
9. What are Fungi? - Types and Characteristics
In this lesson, we will examine the group of organisms known as the fungi. This group includes the familiar organisms mushrooms, yeasts and molds. We will look at several major characteristics of fungi, as well as a few disease-causing fungi.
10. Glycolipids: Definition, Function & Structure
While you may be unfamiliar with the term, glycolipids perform several important functions in the human body. In this lesson, we'll take a look at the parts and purpose of glycolipids.
11. Halophiles: Definition, Examples & Classification
Some organisms thrive in conditions that would be impossible for the rest of us. In this lesson, you will learn about a group of unique organisms known as the halophiles.
12. Infectious Agents: Definition & Types
Infectious agents are tricky little invaders. They sneak in, use your body, and often make you sick in the process. In this lesson, you will learn about the different types as well as some common examples of each.
13. Listeria Monocytogenes: Symptoms & Treatment
In this lesson, you will learn about Listeria Monocytogenes and the illness that they cause. We will look at the symptoms and treatments. There is a short quiz at the end to check your knowledge.
14. Mitochondrion: Definition, Function & Structure
In this lesson, we'll learn about a microscopic structure known as a mitochondrion, one of many organelles responsible for a lot of what goes on inside of us. We'll discover how mitochondria are structured and work, as well as why they're so important to cells and all living things.
15. Scientist Robert Koch: Biography & Facts
Robert Koch (1843 - 1910) was a German physician and scientist who won the Nobel Prize for his microbiological work on tuberculosis. He also established many foundational techniques for microbiology, some of which are still used today. In this lesson, learn more about this innovative scientist.
16. What Are Biofilms? - Definition, Formation & Examples
In this lesson, you'll learn what bacterial biofilms are and how they form. Learn about the positive and negative sides of biofilms and where you can find them growing.
17. What Are Microbes? - Definition, Types & Uses
Microbes are the tiny microorganisms that inhabit the world with us, around us, and even in us. Learn more about how these microscopic beings affect our lives.
18. What is Vascular Disease? - Types, Symptoms & Treatment
Learn what causes vascular disease, some different types of vascular disease, the risk factors for its onset and clinical options for diagnosis and treatment.
19. Sepsis Infection: Definition, Symptoms & Criteria
In this lesson we'll be looking at sepsis infection, which is an infection that affects the entire body. After learning about sepsis, you can test your knowledge with a quiz.
20. Surgical Asepsis: Definition, Technique & Examples
An operation is about to begin. Necessary components include: surgeon, nurses, patient, instruments, and... surgical asepsis! In this lesson, learn about the importance of maintaining surgical asepsis during a medical procedure.
21. Ascaris Lumbricoides: Symptoms & Treatment
Ascariasis is an infection caused by the parasitic roundworms Ascaris lumbricoides. Read this lesson to learn what the symptoms of an infection are and how it can be treated.
22. Life Cycle of the Ascaris Lumbricoides
Ascaris lumbricoides is a type of parasite that can infect humans. Like many parasites, they have a fascinating life cycle. In this lesson, learn how they spread, how they grow, and what effect they can have on humans.
23. Definitive & Intermediate Hosts in Parasitic Life Cycles
Parasites utilize hosts in many different ways. In this lesson, we'll look at two different kinds of hosts, definitive and intermediate, and how they support different stages of the parasite life cycle.
