CASE STUDY OF A PATIENT WITH BRONCHIECTASIS INTRODUCTION The respiratory system is divided into upper and lower respiratory system. The upper respiratory system refers to the nose‚ pharynx and associated structure while the lower respiratory system contains the larynx. Bronchiectasis is an uncommon type of chronic obstructive pulmonary lung disease. Bronchiectasis can be categorized as a chronic obstructive pulmonary lung disease manifested by airways that are inflamed and easily collapsible‚ resulting

1 1. Explain the principle of positive staining. (3 marks) Positive staining is done by staining the cell walls of Gram-positive bacteria with crystal violet. The cell wall of Gram-positive bacteria is made up of a thick layer of peptidoglycan which undergoes dehydration during decolourisation causing the pores to shrink. This shrinkage of pores traps CV-I complex and stain the cell purple. 2. Using a flow chart‚ outline the process of gram staining. (5 marks) Flood the slide with crystal

Section 4 Biol 311 Staining and Identifying Unknown Bacteria Introduction: The microbiology lab up to this point has been used to teach the students how to stain and identify bacteria. There are several types of staining through which the bacteria can be identified based on the color and shape. The staining methods used in the lab are Gram Staining‚ Capsule Staining‚ Endospore Staining‚ and Acid Fast staining. One of the most significant method of staining is the Gram Staining‚ as it is highly dependent
