Blood Agar and Hemolysis
By Kristine Snow
Learners examine microscope images of blood agar and the various types of hemolysis that can be detected. A quiz completes the activity.
"I Want to Be Well" Case 5: Parasitology
By Dawn Madl
Students make observations and formulate an evaluation that includes diagnosis, microorganism identification, and treatment.
The Regulation of Inducible Operons
By Richard Wilkosz
In this animated learning object, learners examine the regulation of inducible operons in bacterial systems.
Correlation of Colony Morphology with Gram Stain Results
By Pat Griffin, Mary Beth Boettcher, Marise Hussey
Students choose the hypothesis and practice describing bacterial colonies using the steps of the scientific method.
Urine Colony Counts (Screencast)
Learners watch a brief video clip. They then follow step-by-step instructions on how to do a urine colony count and examine the criteria for determining if a colony count represents an infection. A brief quiz completes the object.
Test Your Knowledge of Miscellaneous Bacteria
By Marise Hussey
Learners match diseases with their portals of entry, causative agents, and associated vectors.
Audiology
By Donna Matusewic
Learners read about audiological tests including pure tone testing, air conduction, bone conduction, Speech Reception Threshold, and Speech Discrimination Score. They listen to sounds and words recorded at different decibel levels and see a graphic representation of decibel ranges. A brief review concludes the activity.
"I Want to Be Well" Case 2: Bacterial Pathogens
In this interactive object, learners review the case of a patient with meningococcal meningitis.
"I Want to Be Well" Case 1: Respiratory Pathogens
In this learning activity you'll observe information and formulate an evaluation that includes diagnosis and microorganism identification.
Etiologic Agents of Bacterial Diseases
In this interactive object, learners match the bacterial etiologic agent to the disease it causes.
"I Want to Be Well" Case 3: Respiratory Pathogens
In this learning activity you'll make observations and formulate an evaluation including diagnosis and microorganism identification.
"I Want to Be Well" Case 4: Parasitology -- "I Can't Sleep."
Students make observations and formulate an evaluation that includes diagnosis and microorganism identification and treatment.
Endospores (Screencast)
Learners read about endospores and view video clips demonstrating spore staining procedures. Correctly stained slides are shown.
Virus Matching Exercises
Learners complete two exercises. In the first quiz, they divide viruses into two categories: RNA and DNA. They later match each virus with the disease it causes.
Fungal Disease Matching Exercises
Learners test their knowledge of fungal diseases by completing six exercises.
Mannitol Salt Agar
In this overview, students examine and identify mannitol positive and mannitol negative bacteria on mannitol salt agar.
Conjugation
In this learning activity you'll analyze the basic steps in conjugation and applies the effect to microbial characteristics.
Parasite Matching Exercises
By Elizabeth Yoon
Learners match the names of parasitic organisms to the diseases they cause and the modes of transmission.
Components of a Prokaryote (Screencast)
In this learning activity you'll assemble the components of a prokaryotic cell and match the names and functions with each structure.
Audiograms
Students read a description of audiograms. They review audiograms representing various degrees and types of hearing loss.
Virus Particles: Structure and Function
In this learning activity you'll assembles parts of a virus and match virus terms and descriptions.
Helpful Microbes in Your Daily Life (Screencast)
In this screencast, learners read how microbes in such items as yogurt, bread, insulin, and insect sprays improve our lives.
Antibiotic Susceptibility
In this learning activity you'll investigate the interaction of antimicrobial therapies and host defenses in eliminating an infection.
Host Defense
By Kristine Snow, Judy North
The student categorizes defense mechanisms as specific or non-specific.
Metabolic Pathways
In this screencast, learners categorize different metabolic activities as catabolic or anabolic and follow a glucose molecule through the processes of glycolysis, aerobic respiration, and fermentation.
