Lab12:BacteriaoftheRespiratorySystem Introduction: Therespiratorysystemisdividedintotwoparts:theupperandlowerrespiratorysystems.Thelowerrespiratorysystemisanaxenicenvironmentbecauseof the cilia that lines the respiratory tract, alveolar macrophages and IgA antibodies found in the mucus. The upper part harbors a variety of microbiotasuch as Gram-negative bacteria Hemophilus, Gram-positive bacteria such as Staphylococcus aureus and diphtheroids that can cause opportunisticinfectionsleading toinf...
