Lab 11: Bacteria of the Skin Learning Objectives: • Identify the growth of skin bacteria on different types of selective and differential media. • Identify pathogenic from non-pathogenic bacteria Introduction: Our skin forms the first line of defense. It has several characteristics that makes it an inhospitable environment for the growth of most microbes. Some of these characteristics of skin include: high percentage of salt, low pH from 4-5.5, sebum, antimicrobial chemicals; an outer...

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...
