What This Document Is
This document is a student assignment – a “Microbial Safari” – completed for BIO 226, Microbiology for Health Professionals at Drexel University. It involves observing and describing bacterial colonies grown from samples taken in a bathroom environment (sink, around the sink, and drain). The assignment focuses on applying morphological characteristics to differentiate between bacterial growth.
Why This Document Matters
This assignment is designed for students learning foundational microbiology techniques. It’s used to practice observational skills and descriptive terminology related to bacterial colony morphology – a crucial skill for identifying and characterizing microorganisms. It’s likely part of a lab component of the course, reinforcing concepts taught in lectures about bacterial identification and environmental microbiology.
Common Limitations or Challenges
This document represents *one* student’s observations and interpretations. It does not provide a comprehensive guide to all bacteria found in bathrooms, nor does it offer definitive identification of the observed colonies. It’s a practice exercise, not a diagnostic tool. Users should not rely on this document for accurate bacterial identification without further laboratory testing.
What This Document Provides
This assignment includes: detailed morphological descriptions of two bacterial colonies (Colony A and Colony B) based on form, size, elevation, margins, appearance, consistency/texture, and pigmentation/color. It also contains observations on the amount and diversity of bacterial growth on BHI agar plates collected from different locations around a bathroom sink (around the sink, sink bowl, and sink drain). The document also includes a partial answer to a question regarding the total amount of bacteria found in each location. This preview *does not* include the complete answer to the question about bacterial totals, nor does it include any further data or analysis beyond what is presented in the excerpt.
