P1: you must explain how infections are caused by‚ bacteria‚ viruses‚ fungi and parasites. P2: you must explain how pathogenic microorganisms grow and spread. In this assignment I am going to explain how infections are caused by‚ bacteria‚ viruses‚ fungi and parasites. I will then explain how pathogenic microorganisms grow and spread. Infection is the process where germs enter a susceptible area in the body‚ where they multiply‚ resulting in disease. Colonisation is where microbes are present

infectious protein contains high proportion of beta sheet in place of normal alpha helix. The increased content of beta sheet in PrPSc leads to the formation of aggregates resistant to proteases that assemble into amyloid fibers and accumulate to form plaques in brain cells (2). Prions are extremely small unique pathogens and have no nucleic acid. The PrpSc protein cannot self replicate but causes other normal prion proteins to change the conformation making them infectious. The process by which the infectious

Introduction to Clinical Dermatology We’ll start with the basic structure of the skin‚ and as we probably know‚ the skin consists of two layers: dermis and epidermis. The epidermis has only one type of structures which are cells -no blood vessels‚ no lymphatics-‚ and the majority of those cells (about 85% of those cells) are called “keratinocytes”. The rest are called melanocytes‚ merkel cells‚ and langerhans cells. The cells in the epidermis are arranged into 4 layers: * Basal layer: it

INTRODUCTION In the diet of every nation‚ milk is considered as nature’s perfect food. The consumption of milk and its food products have been increased as a sign of prosperity. The growing underdeveloped countries in the last few decades have adopted milk and its food products in their diets. Milk can be defined as the fresh and clear lacteal secretion practically free from colostrums and obtained by the complete milking of one or more milky animals like cow‚ buffalo‚ goat etc. In human

1 Biology 2070H - Lab #1 MICROSCOPY AND CHARACTERIZATION OF CELLS Introduction: Cells can be very difficult entities to study. They are usually very small and transparent‚ yet extremely complex. Fortunately‚ there are many tools available to the cell biologist that aid in their study. The light microscope is to this day perhaps the single most important instrument used in Cell Biology. It is used under bright field conditions to study the organization of cells in fixed and stained sections
