Bacterial infections are normally treated with a course of antibiotics. Viruses are made up of genes and proteins that spread throughout the body by invading the body’s own cells so they can reproduce and multiply in the body. They use the body’s cells as a host because they are unable to multiply on their own. They are normally spread directly from human to human. Viruses can be very tough and there are not many effective medicines available for viral diseases.
However, these bacteria do not grow in the air – conditioners in cars or windows (Centers for Disease Control, 2011). The Legionella species is a group of intracellular pathogens which survive well in aquatic environments. There are different species and serotypes of Legionella. The one that is responsible for most of the lower respiratory tract infections is the L.pneumophila serotype 1. There are other human pathogens which were documented as members also of the Legionella species.
Identify the differences between bacteria, viruses, fungi and parasites Answer: Bacteria Bacteria are single-cell microorganisms which generally exist in large numbers and are microscopic in size. Bacteria can be either beneficial (bacteria in the intestinal tract aid digestion and are part of the normal body flora) or can be the cause of disease (for example pneumonia, food poisoning or bacterial meningitis). Viruses A virus is an infectious agent which can only live and replicate inside organism cells. The main difference between viruses and bacteria is that they are unable to reproduce in food – they need a living host cell to replicate. They replicate by infecting and taking over the functions of the host cell.
1.2 Identify common illness and infections caused by bacteria, viruses, fungi and parasites. Viral and bacterial infection Viruses: Viruses can affect many different parts of the body or more than one body system at the same time for example a runny nose, sinus congestion, cough or body ache. Viruses can cause the classic common cold or even the flu, much
Parasites survive by feeding from its host. 1.2 Bacteria, common illnesses caused by bacteria are MRSA, Salmonella, Legionnaires disease, food poisoning, Pneumonia and Bronchitis. Viruses, common viruses are A common cold, measles, chicken pox and HIV. Fungi, common fungi are, Athletes foot, Ringworm and yeast infection. Parasites, common parasites are, Malaria and worms.
1.2 Identify common illnesses and infections caused by bacteria, viruses, fungi and parasites The most common illnesses and infections that occur due to bacteria, viruses, fungi and parasites are Dioreah, Vomiting, Influenza, Nail infections, Tick bites, Colds, Skin Conditions, Digestive Problems ( Parasites - Worms ) and in some cases, Death. 1.3 Describe what is meant by “Infection” and “Colonisation” As defined by : www.freedictionary.com INFECTION Invasion by and multiplication of pathogenic microorganisms in a bodily part or tissue, which may produce subsequent tissue injury and progress to overt disease through a variety of cellular or toxic mechanisms. This means that Infection is the process of infecting or being infected. COLONISATION A mass of microorganisms in a culture that originates from a single cell. This means that when either a Virus, Bacteria, Fungi or parasites in the single form, gather and join to make one mass of either Virus, Bacteria, Fungi or parasites.
Measles is spread via respiratory fluid referred to as droplets that become airborne and can also be spread simply by contact with a contaminated surface though this is less common as the virus does not appear to survive long on dry surfaces. Of course, as with most viral infections, the infected person can spread the virus before having symptoms. There is currently no medical treatment to cure any virus. There are medications that can hinder viral reproduction/replication; however, these medications have been developed for only a select few virus types. For most viral infections, only supportive care like symptom treatment and complication management, is available and is given while the viral illness runs its natural course.
The causes of initial hospitalization generally fall into three categories. The first is from the disease itself, such as inflammation or organ failure. The second is from other conditions, such as heart disease or diabetes, which commonly coexist with lupus. The last category included infections. It has been noticed that the same drugs that suppress the immune system so that lupus can't attack the body also reduce a person's ability to fight off bacterial and viral infections.
Whooping cough is spread from person-to-person by droplets traveling through the air that carry bacteria from a cough or sneeze of an infected child. Since the pertussis vaccination did not have a high success rate, the use of “the latest wonder drugs, aureomycin and chloromycetin, help[ed] to overcome the infection and therefore shorten the duration of the illness” (Van Dellen
Jacklyn Casper Written Communication Learning Plan 4 September 26, 2012 Living with MRSA Methicillin-Resistant Staphylococcus Aureus, also known, as MRSA is a serious infection that can become life- threatening if left untreated. Most carriers don’t realize they have this infection due to no symptoms. This staff infection can cause physical pain and emotional stress, but keep in mind that it can be managed. There are steps you need to take to become aware of what this infection is, how to avoid spreading it to your family and friends, and living with MRSA. Staphylococcus Aureus is a bacteria that runs in the blood, which may or may not cause an infection on the body.
