Fungi infections, there are several types of fungal infections. Superficial infections affect the skin examples of such infection are athlete’s foot, oral thrush and vaginitis. These types of infection although unpleasant and annoying are rarely serious. Superficial fungal infections are easily diagnosed and treated. Systemic fungal infections are when the fungus gets into the blood stream and can cause serious diseases.
It is a microscopic organism consisting of genetic material. They cannot reproduce without a host cell. Several human diseases are caused by viruses which include:- smallpox, measles, the common cold, chickenpox, hepatitis, HIV, cold sores, shingles to name but a few. Viruses can spread from person to person, and by exchange of salvia, coughing, sneezing. Fungi Fungi are skin infections caused by dermatophytes and yeasts, which are groups of fungi that are normally harmless.
It begins at the site of a break in the skin (a surgical or non-surgical wound). In order for someone to contract necrotizing fasciitis, the bacteria must be introduced into the body. Group A Strep is the same bacterium that causes strep throat This group of bacteria is responsible for mild cases of sore throat (pharyngitis), skin infections, as well as rare, severe illnesses such as toxic shock syndrome and necrotizing fasciitis. However, there are various strains of the bacteria, some of which are more powerful than others. With the right set of conditions, necrotizing fasciitis is a real risk and can cause severe damage.
They are commonly found as spores and molds in the environment and as yeast in humans. 008.1 ac[1.2] identify common illnesses and infections caused by bacteria, viruses, fungi and parasites Common illnesses caused by bacteria include chlamydia and Salmonella; these are caused by harmful bacteria, which are also known as pathogenic bacteria. The human body will try and fight these off but they can also be treated with antibiotics if deemed appropriate. Common illnesses caused by viruses include the common cold and flu. Although you can have a flu vaccination there is currently no vaccination for a cold.
Viruses: A virus needs a host cell to replicate. Viruses are immune to antibiotics and are spread in the air or by direct contact, which mean they probably are more commonly caught from each other. They can lead to serious or sometimes deadly diseases such as aids. Virus can also cause chickenpox, common cold and influenza. Parasites: A parasite is an organism that lives in another organism.
They also feed on many Bacteria in decaying matter organisms to survive. Parasites are organisms that attach themselves to a host to infect, reproduce or spread diseases that it would be carrying. (2) Common illnesses and infections caused by Bacteria, Viruses, Fungi and parasites would be as follows. Bacteria which is present in food for example can cause Food Poisoning, Salmonella, Botulism, and other internal infections of the Stomach. Typical Viruses are illnesses like smallpox, measles, mumps and tuberculosis etc which can be contracted by touch or being within an environment that has the virus in the air.
Disease Yersinia pestis The Plague Jesus Urquijo Biology 113 Lab March 18, 2013 Microbes are what make the world what it is today. They are found in nearly every environment on earth. Each species has its own way of getting nutrients and adapting to its environment, such as pH, aerobic and anaerobic conditions, and enzymes that are essential for optimum living. The majority of bacteria living on earth are harmless if not beneficial to the human race, but those few microbes that are harmful to humans are those that cause disease. They are referred to as pathogens and need to be observed so we can prevent the spreading of disease caused by those particular microbes.
Also known to cause TSS (Toxic Shock Syndrome).Group A Streptococcus, this is a bacteria found in the throat or skin area. Signs and symptoms of impetigo are red sores that pop fast ooze for a couple days then crust itching, and painless fluid-filled blisters. Types of impetigo and their particular symptoms, Impetigo Contagiosa, also known as nonBullous Impetigo. This is the most common form of impetigo. It starts off as a red sore usually around the mouth region either ooze fluid or pus.
• Diagnosis is definitively made when E. coli 0157:H7 is isolated, usually from the patient's stool, and identified as serotype 0157 by immunologic tests. • Most E. coli 0157:H7 infections resolve spontaneously and require no treatment; however supportive treatment is usually quickly required if the patient becomes dehydrated, anemic, or develops HUS or TTP. • The majority of E. coli 0157:H7 infections have excellent outcomes. If complications develop such as severe dehydration, anemia, HUS or TTP, the outcomes can decline from good to poor
Once introduced to an antibiotic, if not eradicated, the bacteria will produce “offspring” that are resistant to that particular antibiotic (VanMeter, VanMeter, & Hubert, 2010). In addition, plasmids (freely-moving pieces of DNA in the cytoplasm) often carry genetic material for resistance and can transfer it from one cell to another, even crossing bacterial species (McKinney, 2013). Compounding the issue, the overuse of antibiotics has given resistance to many strains and many species that otherwise would never have been exposed. Practices like prescribing a much more powerful antibiotic than is necessary combined with patients’ tendencies to stop treatment once they feel a relief of symptoms have only strengthened latent bacteria (Aziz, 2013). Some doctors report that they feel obligated to provide a prescription to a patient, even when the cause of the illness is not yet proven to be bacterial (Bersch, 2010).
