The Black Death The Black Death, known as the Black Plague, or the Bubonic Plague killed one third of the population of Europe during the 13th and 14th centuries. The beginning of this plague set the scene for years suffering. It left the social and economic world in pause. The Black Death became a subject of art, music and folklore and it influenced the mind of the people. The impact of this mass killer caused disorder to the medieval society because of its unknown origin, the unknown causes and preventions, its deathly symptoms and its breakdown of life.
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.
“People become the vessel in which the disease is housed. Whomever comes into contact with this individual will then become infected and then spread this infection to whomever they come into contact with. This is how whole towns and cities were destroyed by the Black Death.” (Wiesner) Inb Khaldun is an Islamic religious man, who believed that the main reason for the Black Death is the corruption of air, through too large of a population in a certain area. It results from the many evil moistures that air has contact with in a dense population. When air is
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.
The scrub typhus group has been reclassified as a new genus, Orientia. The scientific classification of Rickettsia rickettsii is as follows: Domain is bacteria, Phylum is proteobacteria, Class is alphaproteobacteria, Order is Rickettsiales, Family is Rickettsiaceae, Genus is Rickettsia, and there are over 25 different Species. Rickettsia is more widespread then previously believed and is known to be associated with arthropods, leeches and protists. Rickettsia species are carried by ticks, fleas and lice that cause disease in humans such as typhus, rickettsialpox, Boutonneuse fever, African tick bite fever, Rocky Mountain spotted fever, Flinders Island spotted fever and Queensland tick typhus, also known as Australian Tick Typhus. The majority of Rickettsia bacteria are susceptible to antibiotics of the tetracycline group.
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
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.
Bacteria is a single-celled microorganisms that cause diseases. Examples of bacteria are salmonella, campylobacteriosis, clostridium, and tularemia. Feline viral respiratory disease is a severe contagious illnesses of cats that spread fast in a multicat home. The fungi family comprises of mushrooms living in soil and biological material, most types of fungi are spread by airborne spores. “Rickettsia is a disease-causing parasites that are carried by fleas, ticks, and lice.
But which was more significant? In this essay I will explain the two events and give my opinion on which event was more significant. The first of the two events was the Black Death. The Black Death was a terrible plague that happened in the 1300s. The disease spread from nation to nation, killing millions of people and seriously affecting their lives especially Britain.
WHAT IS IT PART Well the black death is one of the most devastating pandemics in human history, a plague that swept through Europe and Asia which killed millions in the 1300's. A plague is a disease that spreads extremely quickly and kills many people violently. Most scientist think that the Black Death was caused by a type of bacteria called Yersinia Pestis carried by the oriental rat flea. These fleas infested black rats and unfortunately, due to the unsanitary lifestyles of humans during the Middle Ages, these rats were literally everywhere. Once contracted by a human the disease became airborne.
