BIOS 242 Week 5 Lab 2; How Germs Spread (v1)

Lab 10: How Germs Spread Learning objectives: • Identify how germs spread • Explain the spread of germs • Identify the importance of good handwashing. Germs spread in many different ways. Direct contact, indirect contact, aerosol transmission, sexually transmitted or through a vector. In this lab, we will observe how germs spread. Materials: Glow in the dark gel, Black light Method: 1. Wear personal protective equipment including lab coat, safety glasses and gloves. 2. Inst...

Lab 12: Bacteria of the Respiratory System Introduction: The respiratory system is divided into two parts: the upper and lower respiratory systems. The lower respiratory system is an axenic environment because of the cilia that lines the respiratory tract, alveolar macrophages and IgA antibodies found in the mucus. The upper part harbors a variety of microbiota such as Gram-negative bacteria Hemophilus, Gram-positive bacteria such as Staphylococcus aureus and diphtheroids that can cause opport...
