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.
They draw nourishment and other needs from their host organism. Parasites that cause infection and disease are known as Pathogenic parasites Identify common illnesses and infections caused by bacteria, viruses, fungi and parasites Virus Common cold, flu, mumps, measles, Chicken pox, Cold sores, HIV,
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.
Although they are eukaryotes like plants and animals, the major difference is that fungal cells have cell walls that contain chitin, unlike the cell walls of plants, which contain cellulose. Fungi lack the chlorophyll necessary for photosynthesis and must therefore live as parasites or saprophytes Parasites: plant or animal that at some stage of its existence obtains its nourishment from another living organism called the host. Parasites may or may not harm the host, but they never benefit it. They include members of many plant and animal groups, and nearly all living things are at some time hosts to parasitic forms. Many bacteria are parasitic on external and internal body surfaces; some of these invade the inner tissues and cause disease.
Plants, animals, humans, fish, birds and reptiles can all be host to parasites. Head lice, thread and other worms are all parasites; they survive by feeding on the blood of their host. Some bacteria and viruses could be considered parasites. 1:2 Identify common illnesses and infections caused by bacteria, viruses, fungi and parasites Bacterial Infections: Salmonellas/ food poisoning, tuberculosis/TB, MRSA, coccidiosis, food poisoning, dysentery, bronchitis, ear infections, tonsillitis. Viral
The parasite is dependent on its host for survival, it has to be in the host to live, grow and multiply. Although a parasite rarely kills the host, in some rare cases it can happen. It uses the host to gain strength, and the host becomes weak. It is responsible for causing various diseases such as, malaria, tapeworm, ringworm and roundworm. There are also parasites which live on the
The ringworm found on the body is usually spread through pets. The symptoms of ringworm are: scaly round or oval patches on the scalp with hair loss in the same area, rashes are itchy and/or inflamed, and bald spots. Ringworm is spread from person to person by touch or by using items that had been used by the infected
P1: Explain how infections are caused by different pathogens: * Bacteria * Fungi * Protozoa * Parasites * Viruses Bacteria: Pathogens are microorganisms such as viruses or bacteria and these cause diseases in the body. Bacteria is a pathogen and are microscopic living cells that multiply at a rapid speed, once inside the body they spread toxins making the individual ill. Bacteria can cause diseases such as; * food poisoning * cholera * typhoid * whooping cough * gonorrhoea - a sexually transmitted disease Bacteria can travel in many things such as food, water or even through the air. For example if an individual is sitting next to someone that keeps on sneezing, the individual will eventually
Insect saliva inactivates blood components and manipulates host immunity The animal blood feeding is an essential event associated with the life cycle of mosquitoes. The female mosquito applies specific strategies for sucking blood from their animal hosts. The mosquito injects saliva at the site of piercing the host skin before drawing the blood. Mosquito saliva is the soup of a complex array of pharmacological agents that perform numerous important functions to facilitate the process of blood feeding [16]. During blood feeding, the damage caused to the host blood vessels usually results in vasoconstriction that may increase insect feeding time due to restricted blood flow to their mouth parts.
Disease Research Short Paper [pic]Disease Topic : elephant disease. Etiology it is caused by parasitic worms invading the body's lymphatic system - the network of vessels carrying infection-fighting cells. The worm is spread by mosquitoes, who pass it on when they take blood from humans. The bacteria-containing worms lodge in the lymphatic system, producing millions of minute larvae which spread throughout the bloodstream. It is unclear whether the swelling, or lymphoedema, that occurs results from the obstruction of the lymphatic vessels or from the response of the body's immune system to the worms and the bacteria within them.
