Causes and spread of infection 1.1: Bacteria are single-celled microorganisms with a simple cellular organization whose nucleus lacks a membrane. Viruses are DNA wrapped in a thin coat of protein that replicates only within the living hosts. Fungi come in many different varieties and we eat quite a few. Mushrooms are fungi as is the mould that forms the blue or green veins in some types of cheese. Yeast is another type of fungi and is the necessary ingredient to make most types of bread.

The organisation could lose money

importance of the plasma membrane found within and around all cells’ The plasma membrane surrounds all eukaryotic and prokaryotic cells. Eukaryotic cells have membrane bounded organelles whereas prokaryotic cells do not. The plasma membrane forms the boundary between the cell cytoplasm and the environment. Its function are to allow different environments to be established inside and outside the cell. It also controls the movement of substances into and out of the cell. The cell surface membrane which surrounds

Necrotizing Fasciitis is a bacterial skin infection that is caused by one or more bacteria that enters one’s skin through a cut or wound. It can be fatal if not treated in time. Necrotizing Fasciitis is commonly known as the ‘flesh eating infection’ that occurs suddenly and spreads extremely fast. It corrodes the skin and the tissue beneath it. It can be caused by one or more bacteria‚ for example Streptococcus pyogenes‚ Kebsiella‚ Bacteroides and more. Approximately 700 hundred cases are recorded
