Essay about Features of Bacteria, Viruses and Fungi

Very severe outbreaks may have symptoms that include swollen and tender lymph glands in the groin, throat, or under the arms, and even flu-like feelings such as fever, chills, headache, and a general run down feeling.

Pathogens are everywhere. They are in people, animals, and the environment. Pathogens come in a wide variety. The types are fungal, bacterial, viral, and other parasites. All pathogens can be dangerous, but two of them are more dangerous. These two types that more dangerous are fungal and bacterial. While both fungal and bacterial pathogens cause illness, they differ in the way they are transmitted, the way they are treated, and the diseases they cause.

There are three types of environments in which cells are located which include isotonic, hypotonic and hypertonic. In an isotonic environment, the amount of water and solute are the same both inside and outside of the cell. As water drifts into the a cell, the same amount flows out creating a balanced environment both inside and outside of the cell. When there is a high level of water on the outside of the cell and a high amount of solute inside the cell, water will be drawn inside of the cell creating a hypotonic solution. The increase in water inside the cell causes the cell to become engorged and erupt. In a

In this assignment I am going to explain how infections are caused by, bacteria, viruses, fungi and parasites. I will then explain how pathogenic microorganisms grow and spread.

- wounds and breaks in the skin (pathogens enter the body through mucus membranes, nose, mouth, gut, genital urinary track - catheters, or wounds like surgical incisions which can cause e.g. MRSA).

| Usually caused by a virus, can be spread in much the same way as the common cold.Children can also become infected if they have contact with fluid from the blisters or saliva of someone who is infected.

Respiratory (airborne infections breathed in), digestive (within foods/ drinks), blood circulation (via broken skin/ wounds), body fluids (sexually transmitted diseases, cross contamination, poor hygiene).

Structure and function in Biology is a broad concept that can be explored within a diverse range of topics across the subject matter. The following essay will be focussed mainly on the subject of Deoxyribonucleic Acid, or more commonly DNA. DNA is a highly complex, intricate and extraordinary macromolecule found within all living cells. DNA is a "biochemical noun" and can be defined as "...a self-replicating material which is present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information." [Oxford Dictionary, c2016] DNA is found in the nucleus of eukaryotic cells, enclosed within a double membrane. Eukaryotic cells are multifaceted and require a high level of regulation to ensure smooth functioning. The double membrane of the nucleus allows gene expression, a key function of DNA, to be efficiently regulated.

- death rate, # or % of people who have the disease who actually die from it or complications from it. EX: 25% of the people who caught smallpox died from it

ITHACA (WENY) - Monday, President Obama signed legislation that will phase out plastic microbeads found in soaps, body washes and other personal-care products.The bill prohibits the manufacture of products containing plastic microbeads as of July 1, 2017, and phases out sales of such products over the next two years.

bacteria. The main area of this infection is in the bones of the legs but it can also be in the arms or

a bacterial infection has occurred(Carson-DeWitt). Fever and discomfort can be helped by taking acetaminophen (Carson-DeWitt). A cool mist vaporizer may help with the cough (Carson-DeWitt). Fever leads to dehydration, therefore patients must be given lots of fluids and liquids to stay hydrated(Carson-DeWitt).

This is an infectious disease. Infectious diseases are disorder that are caused by organisms such as, viruses, bacteria, parasites, or fungi. Some infectious diseases can be passed from human to human

As for the spread of nosocomial infections, methods include airborne travel, direct person-to-person contact, droplets, vermin transmission (or vector borne transmission) and tangible vehicles found in hospitals. Airborne travel occurs when simple droplet nuclei of microorganisms remain in the air for extended periods of time. An example would be a sneeze or dust particles. Once these particles are inhaled by a host the infection can be contracted. Person-to-person contact is the most frequent transmission and includes a hand shake, touching, rubbing, patting, etc. Droplets are transmitted through certain operations involving the mouth, nose or throat, including bronchoscopy as well as coughing, sneezing and talking. Vermin is also a method of travel for these microorganisms as rats, roaches, mosquitoes and flies. Lastly, common hospital utilities and equipment, when they are not properly cleaned, can become a vehicle for contact. These may include medications, hospital devices, tools and equipment, even water and food.
