BIOS 242 Week 6 Lab 2; Bacteria of Respiratory System

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...

BIOS 242 Week 6 Lab 1; Bacteria of the skin

Introduction: Our skin forms the first line of defense. It has several characteristics that make skin an ideal environment for the growth of most microbes. Some of the characteristics of skin are high percentage of salt, low pH, sebum and an outer layer of dead skin cells that act as a barrier to pathogens. The only organisms that can tolerate high levels of salt are able to grow on skin. Purpose: The purpose of this lab is to learn how to isolate and identify bacteria from skin and learn the ch...

BIOS 242 Week 6 iLab: Specific Immunity Introduction This lab experiment was done to see if there were any pathogens in the watermelon that a student ate after it falling in the barn. My case study involved students being at a barn and everyone enjoying and playing games. One of the students dropped his slice of watermelon in the barn. He picked it up, and simply just rinsed it off and proceeded to eat it. The sponsor knew the watermelon would be harmful, so took the slice and put it in a plas...
