They differ from bacteria by needing a living host to complete their life cycle, being host specific. Some of their common illnesses and infections include scabies, malaria, bed bugs, lice and tape worm. Infection is an invasion of the body by a foreign substance such as germs, microbes and parasites, that can infect the body in numerous ways. Systematic infection can affect the whole body, possibly
Understanding the causes and spread of infection The differences are that bacteria are an organism which produces toxins which grow and then divide. Virus - are smaller than a cell. It can't reproduce outside the cell unlike bacteria, so they invade the cells and inject the genes into the nucleus and creates copies of itself Fungi - causes disease by absorbing nutrients, and producing toxins Bacteria, fungi and viruses are all separate entities and are completely different from each other. Parasites, however, can refer to a number of different things including bacteria, fungi and viruses. A parasite is any organism which lives inside a different organism in a symbiotic relationship in which only the parasite benefits from the symbiosis.
Viruses are classified into three main groups: animal, plant, and bacteria (B2). Then bacteria is broken up into two more groups: archebacteria and eubacteria. A typical virus is composed of DNA or RNA and is surrounded by a protein coat. Pneumonia is one virus that can affect the community is Pneumonia. There are many things that go or come with Pneumonia, so here is some background information.
Abscess: localized collection of pus Infections associated with traumatic injuries, such as animal or human bites, burns, cuts, frostbite, or penetration of foreign objects. Many organisms are capable of causing infection in wounds. Incisions, Punctures, Lacerations, Contusions, Abrasions, Gunshot wounds, Burns Tissue components: Collagen, Finbronectin, Fibrinogen, Fibrin Anaerobic wounds Staphylococcus, Streptococcus, Pseudomonas aeruginosa, Clostridium species 1. Staphylococcus aureus& Staphylococcus epidermidis : pyogenic cocci, inflammatory reaction causes swelling, redness, pain, infection can become systemic Toxic shock syndrome: fever, muscle aches, shock, diarrhea. Toxin produced is responsible for the infection Staphylococcal toxins can also act as superantigens Cleaning and removal of dirt reduces rates of infection Antibiotics, resistant strains 2.
Burns <25% TBSA produce primarily local response an >25% TBSA local and systemic response. Skin functional changes such as loss of surface, layers of dermis and epidermis, cause inability to regulate body temperature and body cells necrosis disrupt it metabolic function and damage to peripheral microcirculation. Some cells are destroyed instantly. Others are irreversibly injured. Cellular damage is distributed over a spectrum of injury.
Which (s) condition is the drug Ceftriaxone used to treat? is used to treat many kinds of bacterial infections, including severe or life-threatening forms 5. What does the abbreviation CMV mean? cytomegalovirus 6. Which (s) condition is the drug Colace used to treat?
Parasite Co-Infections PARASITIC DISEASES OF MAN Parasites can exist inside a host, like the pig parasite Ascaris suum in which case they are deemed to be an “endoparasite”. They may also live on its host such as head lice in humans, and are known as “ectoparasites”. They range in size from unicellular organisms (protazoans) to the multicellular species, such as the Helminths. In Blaxter’s 2003 paper on the evolution of parasitism, it is suggested that the large range of lifestyles exhibited by these nematodes and their use of a vast array of hosts, would suggest a relationship between the level of parasitism and their adaptability to survive and flourish in a wide range of challenging environments. Throughout evolutionary history humans have been infected with parasites.
Norovirus is transmitted faecal oral route and are passed from person to person contact, entering the body in food or water. Fungi is any member of a large group of organisms that includes micro organisms such as yeasts and molds and mushrooms. These organisms are classed as a kingdom. Fungi which is separated from plants, animals and bacteria. One major difference is that fungal cells have cell walls that contain chitin, unlike the cell walls of plants which contain cellulose and unlike the cell walls of bacteria.
(3) Etiology: Pneumonia develops when the immune system cannot combat the virulence of the invading organisms. Organisms from the environment, invasive devices, equipment and supplies, staff, or other people can invade the body. Pneumonia can be caused by bacteria, viruses, fungi, protozoa. Noninfectious causes of pneumonia include inhalation of toxic gases, chemical fumes, and smoke and aspiration of water, food, fluid, and vomitus. (4) Signs & Symptoms: Pneumonia may present with a 1-2 day history of cough, fever, dyspnea, fatigue, rigors and pleuritic pain.
There are many ways bacteria can enter the body. Expired, contaminated or non pasteurised food items could be one way. Cuts, sores and open passages such as eyes, ears, genitals etc are also ways in which bacteria can enter the body. Some of the illness and infections attributed to bacteria include e.coli, streptococcus (strep throat, impetigo, cellulites), staphylococcal (skin infection, pneumonia, food and blood poisoning), cholera, mrsa, typhoid, uti’s, dysentery and tuberculosis. Bacterial infections are commonly treated with antibiotics.
