There are several types of parasites such as Ectoparasite- which is a parasite that lives on the host’s surface, examples will be hair and body lice and mites. Endoparasites – One that lives inside the host, for example heartworm, tapeworm and flatworms. Epiparasite- This one feeds on another parasite. For example, fleas and ticks. 1.2 Identify common illness and infections caused by bacteria, viruses, fungi and parasites.
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.
Some of the world’s most serious and deadly diseases are viral. In order to cause disease bacteria must enter the body. Routes for bacteria include; cuts, contact with infected faeces, contaminated food or water, close contact with an infected person, breathing in droplets from an infected persons cough or sneeze or indirectly by touching a contaminated surface. Viruses can be spread from one person to another through coughs and sneezes, vomit, exposure to infected bodily fluids, sexual intercourse and sharing infected needles. Fungi infections, there are several types of fungal infections.
The horsefly is the one that keeps most of the disease carrying bugs off the flapenguin. Without the horsefly, the flapenguin would get infected with the diseases because the horsefly is no longer around to keep the bugs off. Then there would be a few flapenguin in the
The risk of toxic exposure to Malathion is minute, only a small application is used per acre placed on ground. According to the agency for toxic substance and disease, the long-term risk from Malathion application is unlikely. In conclusion, I vote to introduce Malathion into Genericville. I do believe with through proper education of our citizens, the over population of mosquitoes could be under control. Within the planning, we must take in consideration the river and wet lands; our water supply, possibly of residue being left over, and most importantly safety of
For instance, Lactobacillus acidophilus — a harmless bacterium that resides in your intestines — helps you digest food, destroys some disease-causing organisms and provides nutrients. Many disease-causing bacteria produce toxins — powerful chemicals that damage cells and make you ill. Bacteria can multiply very rapidly if given the right environment. Viruses are much smaller than cells. In fact, viruses can only be seen by electronic microscope. To reproduce, viruses invade cells in your body, hijacking the machinery that makes cells work.
Giardia lamblia is a single celled organism that causes a diarrheal infection of the small intestines and is one of the most common parasites in the United States. Giardia lamblia is a flagellated protozoan parasite which means it is an organism with one or more whip-like organelles called flagella. Flagellum is a hair like appendage that protrudes from the cell body, and it is how the organism moves around. The infectious agent can be transmitted by ingesting or swallowing water, food, or soil that is contaminated with giardia cysts (hard shells containing giardia). Some examples would be public swimming pools or spas.
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.
This bacterium is also a facultative anaerobe meaning it can grow with or without oxygen. The bacterium is found most commonly in animals such as rats, fleas, lice, chipmunks, etc. Y. pestis is most commonly transferred through bites from affected animals, direct contact with infected tissue or body fluids, or inhaling infected droplets. The best way to avoid the plague would be to stay away for any animal that has potential for having Yersinia pestis If proper safety measures are not taken and a human ends up with the plague they would have general symptoms such as inflamed lymph nodes, fever, chills, muscle aches, headache and weakness. If left untreated the symptoms could worsen and you could be left with septicemia, food poisoning like symptoms, bleeding from under the skin, in the urine, from the mouth and nose, shock, kidney failure, breathing problems.
Nowadays, there is a vaccine for the Black Plague but its takes awhile for it to become fully effective. There are drugs like antibiotics and sulphonamides that are used to treat it as well (“The Modern Day Black Death...”). Most people who contract the disease survive if they are given the right antibiotics in time. Good sanitation and cleanliness is a good way to prevent the bacteria from growing (“Plague”). During the time of the Plague, there was no medicine that could cure or help alleviate the disease.
