These black rats like to live near or in human housing. This highly contagious infection is spread to humans by fleas that are biting the black rats and contracting the infection. The infected flea then bites a human and leaves the infection in the flea bites. When an over populated area of black rats becomes more over populated this can be another cause of the spread of the Black plaque faster. The growth of population in cities and small towns tend to lead to decline in living conditions, thus leading to famine and epidemics causing more cases if the Black Plaque.
In the meantime they rob your system of nutrition, loading you down with their excretions and secretions these include Lice and Ringworm 1.3 Colonisation is when a bacterial strain invades a region of your body and starts to rapidly divide - it sets up a new colony Infection is similar but only usually used for opportunistic pathogenic bacteria - that is it does not usually refer to bacteria that normally inhabit us 1.4 Localised infection is restricted to a ceratin region of your body Systemic infection means that the infection is throughout your body. This usually means that the bacteria have been able to invade either your ciculatory system or the lymphatic system and spread 1.5 Some of the poor practises that may
Parasites - A parasite is an organism that lives on or within another living organism, it feeds off of the host. It can be very detrimental to the host. 1.2 Identify common illnesses and infections caused by: Bacteria - Clostridium Difficile, (C-Diff) Diarrhoea. Legionella,through water contact, can be water coolers and showers heads Salmonella, is passed human to human through food or water MRSA – usually from urine tract and catheters Viruses - Hepatitus A,B and C. Transmitted through bodily fluids HIV. Transmitted through blood, sexual contact, Influenza.
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.
After being transmitted via the bite of an infected flea the Y. pestis bacteria become localized in inflamed lymph where they begin to colonize and reproduce. Buboes associated with the bubonic plague are commonly found in the armpits, upper femoral, and groin and neck region. Acral gangrene (i.e. of the fingers, toes, lips and nose), is another common symptom. Due to its bite-based form of infection, the bubonic plague is often the first step of a progressive series of illnesses.
A parasite is a tiny organism that lives in or on a host (A body) which they use in order to feed. Parasites can cause severe illness's, there are 3 main types of parasites: protozoa, helminths, and ectoparasites. 2. Bacteria salmonella(food poisioning) e.coli causes abdominal pain,cramps and diarreha Staphylococus found on skin Mrsa responsible for many infections. Viruses common cold,flu mumps and measles.
about 500 to 1,500 happen in the us every year. this disease has two types; type I is caused by anaerobic bacteria with or without the presence aerobic bacteria, type II also called hemolytic streptococcal gangrene is caused by group A streptococci, other bacteria may or may not be present the disease may be also be called synergistic gangrene.Muscle and fat tissue are affected as a consequence of infection. Necrotizing fasciitis is a severe complication of group A streptococcal infection. The bacteria cause the destruction of skin and muscle by releasing toxins. Additional complications can occur from necrotizing fasciitis, such as shock and organ
Buckley (2011)explains the process that occurs when a Blood-feeding insects such as mosquitoes become infected when they feed on infected birds, which leaves the virus in their blood for a few days ( para.2). The virus located in the mosquito's salivary glands; then, the virus can be transmitted when the infected mosquito bites animals or humans. Once a person or an animal is infected with the WNV, the incubation period begins ,the WNV multiplies in the blood system and crosses the blood brain barrier to reach the brain causing “The virus interferes with normal central nervous system functioning and causes inflammation of brain tissues”. (White ,J. D. &Morse, L.D., 2011, p.84) . In a study done by the (CDC, 2011, para 3), a persons over 50 years of age have the highest risk of severe disease, once infected with
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.
This disease is a member of the herpes virus family and can lead to other infectious diseases such as “viral pneumonia, infection of the brain (encephalitis) and bleeding problems” according to the csg.org (2007). Early symptoms can range from a low grade fever, dizziness, fatigue, dehydration, and the worsening of asthma. This disease is most commonly exposed and passed among children, but can be even more dangerous if contracted by adults. It is noted that if you have had chicken pox, the shingle virus is embedded and lying dormant in your nervous system which can cause chronic pain syndrome at the site of the original shingles eruption also known as (post-herpetic neuralgia). Describe the disease, how it is transmitted, and the environmental factors that may make someone vulnerable to it.
