Diseases about cells, bacterias and more!!!Diseases about cells, bacterias and more!!!
Bacteria are used to manufacture food and drugs Are there bacterias in these products? Are they the product of bacterial decomposition?
YES!!!!! Humans have learned that decomposition is occasionally beneficial because it adds flavor to food.
Did you know? Using genetic engineering technology biologists can now “reprogram” bacteria to manufacturate any protein. For example bacteria now produce most of the insulin needed by Diabetics in the United States.
Occasionally your body is a temporary home for parasitic bacteria with serious effects. They cause disease or infection. BACTERIA A disease causing is called a PATHOGEN Tuberculosis Diphtheria Scarlet fever Cholera Leprosy Typhoid They are carried in water, air, food, insects or human contact.
Common bacterial diseases NameMode of transmission Symptoms TuberculosisAirbone water droplets Fatigue, persistent cough, bleeding in loungs, can be fatal. DiphteriaAirbone water droplets Fever, sore throat, fatigue. Scarlet feverAirbone water droplets Rash, fever, sore throat CholeraContaminated water Sever diarrhea, vomiting, ogten fatal LeprosyPersonal contactNerve damage, skin lesions. Tissuee degeneration.
Pathogenic bacteria can contaminate foods and cause food poisoning. Salmonella bacteria found in pork, eggs, poultry. Symptoms: diarrhea, vomiting and abdominal cramps. Hot soapy water will destroy Salmonella bacteria encountered during food preparation. Clostridium botulinum It lives in the soil A comsuption of less than one millionth of a gram causes paralysis and death. It can grow in canned food that have not been properly sterilized.
Bacteria travel through the air A sneeze or cough sprays out a shower or tiny droplets, bacteria that are carried in the water droplets produced by a single sneeze.
Alzheimer's disease, stroke, heart disease and certain cancers can all be linked to a dysfunction of the lysosome, says South Australian biochemical geneticist Professor John Hopwood.
Mitochondrial disease or dysfunction is an energy production problem. Almost all cells in the body have mitochondria, which are tiny “power plants” that produce a body’s essential energy. It’s as if the body has a power failure: there is a gradation of effects, like a ‘brown out’ or a ‘black out’. Autism, Parkinson’s, Alzheimer’ s, Lou Gehrig’s disease,muscular dystrophy and, chronic fatigue

Did you know all this information? Do the cells´malfunction affect to humans? Why?
Are the bacterias Important? Useful? Bad? Why? What can you say about the bacterias?
Let´s check out in detail these deseases!!!
Tuberculosis What is? The disease was called "consumption" in the past because of the way it would consume infected people from within. When a person becomes infected with TB, the bacteria in the lungs multiply causing pneumonia; the patient experiences chest pain and has a persistent cough which often brings up blood. TB is a major cause of illness and death worldwide, especially in Africa and Asia. Each year the disease kills almost 2 million people. The disease is also prevalent among people with HIV/AIDS
Scarlet fever I t´ s caused by an infection with group A streptococcus bacteria. The bacteria make a toxin (poison) that can cause the scarlet-colored rash from which this illness gets its name. The rash is the most striking sign of scarlet fever. It usually begins looking like a bad sunburn with tiny bumps and it may itch. The rash usually appears first on the neck and face, often leaving a clear unaffected area around the mouth. It spreads to the chest and back, then to the rest of the body. In body creases, especially around the underarms and elbows, the rash forms classic red streaks.
Cholera It´s an infection of the intestines. People get it from drinking water or eating food that's contaminated with a type of bacteria called Vibrio cholerae. Cholera can cause watery diarrhea and vomiting, making people who have it get dehydrated quickly.
Leprosy It´s an infectious disease that causes severe, disfiguring skin sores and nerve damage in the arms and legs. The disease has been around since ancient times, often surrounded by terrifying, negative stigmas and tales of leprosy patients being shunned as outcasts. Today, about 180,000 people worldwide are infected with leprosy, according to the World Health Organization, most of them in Africa and Asia. About 200 people are diagnosed with leprosy in the U.S. every year, mostly in the South, California, Hawaii, and some U.S. territories.
Alzheimer's disease It´s a neurological disorder in which the death of brain cells causes memory loss and cognitive decline. A neurodegenerative type of dementia, the disease starts mild and gets progressively worse. It is a neurodegenerative disease, which means there is progressive brain cell death that happens over a course of time
Down syndrome It´s a chromosomal condition that is associated with intellectual disability, a characteristic facial appearance, and weak muscle tone in infancy. About half of all affected children are born with a heart defect. Digestive abnormalities
Cancer It´s a term used for diseases in which abnormal cells divide without control and are able to invade other tissues. Cancer cells can spread to other parts of the body through the blood and lymph systems. The body is made up of many types of cells. These cells grow and divide in a controlled way to produce more cells as they are needed to keep the body healthy. When cells become old or damaged, they die and are replaced with new cells. However, sometimes this orderly process goes wrong. The genetic material (DNA) of a cell can become damaged or changed, producing mutations that affect normal cell growth and division. When this happens, cells do not die when they should and new cells form when the body does not need them. The extra cells may form a mass of tissue called a tumor.DNAmutationstumor
Have you seen this before? Do you know what it is?
This is a story web where the main characteristics are defined and it´s necessary to explain more aspects or set examples.
Can you do it? With all this new information? Ready? In the cardboard, do it, include some images, and then explain it to your classmates
