The standards of the CDC are classified into three categories ( Infection isolation‚ contact and airborne droplet)‚ that take into account the type of exposure and precautions that healthcare professionals need to have in order to prevent infections so the amount and type of PPE used for universal precautions is proportional to the exposure that the

Unit 265 Causes and spread of infection. Outcome 1 Understand the causes of infection 1. Identify the difference between bacteria‚ viruses‚ fungi and parasites? The difference between bacteria‚ viruses‚ fungi and parasites is: Bacteria Bacteria is a single celled organism‚ bacteria have evolved to thrive in almost any environment and can be found in almost any substance/surface and also in the human body‚ only 1% of bacteria is actually harmful. It ’s bad or infectious bacteria that cause illness

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.

(Include a description of the envelope‚ capsid‚ and core The nucleic acid of a virus is protected by a protein coat called the capsid. The structure of the capsid is ultimately determined by the viral nucleic acid and accounts for most of the mass of a virus‚ especially of small ones. Each capsid

To improve the infection control‚ it is essential for the occur in a chain model which starts from the presents of the infection agents as the bacteria‚ viruses‚ fungi‚ parasites‚ and prions in the people‚ food‚ water‚ skin‚ and equipment.

A different volume of E.coli was transferred into 250ml Erlenmeyer/shake flask containing media for the nutrient of microorganism. The different volume of microorganism transferred will give the different effect of reading on the constant volume of media used. There are three ways to test the growth kinetic rate of microorganism on shake flask‚ which are by optical density (OD)‚ glucose analysis and

In addition to scrub attire‚ scrubbed persons must wear a sterile surgical gown‚ mask‚ and gloves within the sterile field to establish bacterial barriers.2‚4 These barriers protect the patient from the transmission of microorganisms from the surgical team. Once the scrubbed person dons the sterile surgical gown‚ the gown’s sterility is limited to the gown portions directly viewed by the scrubbed person. These sterile areas include the gown front‚ from chest to the sterile
