Unit 20 – Causes and Spread of Infection 1.1 Identify the differences between bacteria‚ viruses‚ fungi and parasites. Bacteria‚ fungi and parasites are all considered as ‘living’ things‚. Bacteria are single celled microorganisms that can only been seen through a microscope‚ they collect their nutrition from their surrounding and unlike viruses‚ they do not need a living host to reproduce. Viruses are difficult to destroy because they are enclosed in a protein coating. Viruses are disease-producing

Causes and spread of infection Identify the differences between bacteria‚ viruses‚ fungi‚ parasites? -Viruses aren’t living. They’re only made of complex proteins and nucleic acids. Bacteria‚ Fungi and Parasites are living organisms. - Bacteria are unicellular microorganisms. Fungi and Parasites are multicellular. - Fungi have cell walls made of chitin and they aren’t animals. Parasites and bacteria are animals. Bacteria come in 3 main shapes; spherical which are known as cocci‚ rod shaped

NOSOCOMIAL INFECTIONS Nosocomial Infection is an infection that occurs in a hospital of hospital-like setting. Approximately 10% of American hospital patients contract this infection. There are three factors as to why nosocomial infection exists: 1. A high prevalence of pathogens. 2. A high prevalence of compromised hosts. 3. Efficient mechanisms of transmission from patient to patient. These three factors alone lead not just to a higher chance of transmission

The causes of infection. Diseases can be classified as genetic‚ metabolic‚ or infectious. Infectious diseases are caused by bacteria‚ viruses‚ fungi and parasites that use our body as a host for reproduction and cause illness. Bacteria‚ viruses‚ fungi and parasites. These are all microorganisms which cause infection‚ yet they are all different in structure‚ required environment and conditions needed to thrive and multiply. Bacteria is a single celled organism. It’s shape and size can vary

Impetigo is a common type of skin infection and is highly contagious. Most of the time it can appear on the hands‚ neck and face in children‚ Impetigo occurs rarely in adults but it is a sign of a more severe skin condition. There are many types of Impetigo: Impetigo Contagiosa‚ Bullous Impetigo‚ and Ecythma but out of all of these Ecythma is the most serious because it damages the second layer of the skin. People with Ecythma will have painful blisters that may turn into ulcers‚ scars and swollen

Introduction Hepatitis B infection is one of the major and common liver infectious diseases worldwide‚ and caused by a small enveloped DNA virus‚ the hepatitis B virus (HBV). (Tong 2005Int J med Sci) Importantly‚ over 20 million people are infected annually with HBV and there are globally 350-400 million chronic carrier of HBV. (McMahon 2005.) Routes of infection include vertical transmission (through childbirth)‚ early life horizontal transmission (bites‚ lesions‚ and sanitary habits)‚ and adult

The most common infection in the health care setting is Clostridium difficile (C. difficile) and it is associated with sky rocketing hospital costs‚ deaths and complications. (Zacharioudakis‚ et al.‚ 2015) According to studies released in the United States by the Centers for Disease Control and Prevention (CDC) in 2015‚ the current economic burden of infectious C. difficile has become the most common microbial cause of recurrent antibiotic-associated diarrhea and other gastrointestinal illnesses

Children should be taught how germs spread and how to stop this. It a direct transfer of bacteria‚ viruses and germs. This can occur when a individual with the virus touches‚ coughs and sneezes and runny noses on people who are

Disseminated gonococcal infection is caused by hematogenous infection of N. gonorrhoeae from the primary site of infection. It occurs in both men and women‚ but is seen more frequently in women‚ because women with gonorrhea are often asymptomatic‚ which allows the dissemination of infection before the patient experiences symptoms. Pregnancy‚ menses‚ and terminal component complement deficiencies also increase the risk for disseminated gonococcal infection as a result of endometrial exposure of submucosal
