Canvas deducts grades for late submissions automatically.
Instructor willing to fix grades manually for affected students.
Planning and Preparation
Importance of time management is stressed.
Complete all readings carefully before assignments.
Prepare for lab work within the first hour to avoid crunch time in the second hour.
Discussion Boards in Class
Discussion boards are essential, not busy work.
Objective: to introduce students to microbiology concepts and facilitate discussion among classmates.
Reduced number of discussion boards to focus on quality over quantity.
Current Assignment
Students must find and summarize an article on microbiology.
Article relevance: it should connect to personal health, interesting facts, or other areas of interest related to microbes.
Deadline for submissions is one week from the assignment date.
Essay Requirements
Summary should be in students' own words, keeping in mind the understanding level of classmates.
Importance of communication and avoiding technical jargon that may confuse peers.
Evaluate the article using the CRAB test (Current, Relevant, Authoritative, Accurate).
CRAB Test
Current: Ensure articles are recent; older articles may not reflect current understanding.
Relevant: Article should align with course topics.
Authoritative: Source should be credible, ideally authored by experts in the field.
Accurate: Facts presented must be reliable and well-researched.
Science Writing Tips
Emphasize writing in one's own words rather than relying on AI-generated content for summaries.
AI can be helpful for article searches but not for writing.
Taxonomy Overview
Taxonomy involves classifying organisms, essential for scientific communication.
Useful for understanding relationships between organisms, especially pathogens.
Classifications can help predict behavior and treatment options based on related species.
Importance of DNA in modern taxonomy for deeper insights into organism relationships.
Tree of Life and Domains
Three primary domains cover all life: Bacteria, Archaea, Eukarya.
Eukarya includes a wide range of organisms, including fungi and single-celled microbes.
Tree of life organizes all organisms based on genetic relationships.
Levels of Taxonomy
Domains: Broadest level, covering all life forms.
Kingdoms: Divisions within domains, indicating major groups of organisms.
Phyla: Further subdivisions based on shared characteristics.
Families, Genus, Specific Epithet: More specific classifications leading to unique species identification.
Emphasis on species naming conventions: italicization, capitalization rules.
Importance of Understanding Taxonomy
Allows for scientific consensus about organisms being studied.
Helps identify and relate to new organisms based on known relatives.
Examples of Taxonomy Applications
Understanding relationships among various organisms by examining their taxonomy provides insight into their biology and potential interactions.
Cell Structure Unifying Themes
All cells have cell membranes, which are crucial for maintaining internal environments and selectively controlling entry/exit of substances.
Emphasized that cells, regardless of type, share fundamental cellular structures and functions.
Prokaryotic Cell Membranes
Proteins responsible for various life processes must be embedded in the cell membrane; prokaryotes lack membrane-bound organelles.
Info on how prokaryotes may adapt by folding cell membranes to increase surface area for protein attachment.
Cell Wall Structures: Gram Positive vs. Gram Negative
Gram Positive Cell Walls
Composed mainly of multiple layers of peptidoglycan providing strength and shape.
Smaller or absent periplasmic space compared to Gram-negative organisms.
Potential presence of teichoic acids that distinguish them from Gram-negative.
Importance of Cell Walls
First line of protection for cells against environmental pressures.
Structure aids in identification groups during microscopy and lab work.
Summary
Preparing students for successful lab sessions, discussion engagements, and scientific literacy in microbiology through a structured approach to reading, evaluating resources, and understanding taxonomy is emphasized throughout the notes.
