What are importance of prions?
PrionsA prion is an infectious protein that is misfolded. These proteins can aggregate in the brain and other neural tissue, forming amyloids. Diseases associated with prions include bovine spongiform encephalopathy (mad cow disease), scrapie, kuru, chronic wasting disease, and Creutzfeldt-Jakob disease. Prions are still poorly understood by researchers, and prion diseases (transmissible spongiform encephalopathies) remain untreatable.
Is asthma an infectious disease caused by a bacteria that causes inflammation and calcification in the lungs?
Asthma is not infectious disease. It does not spread from one person to other person.
What systems do prions affect?
Prions affect the nervous system (the brain and other neural tissue).
Can utensils used to cook elk infected with Chronic Wasting disease pass prions on after being washed?
Yes, especially if they haven't been put through a steaming process of over 250 degrees Celsius prior to being used. Steaming through autoclaving is the only way to destroy prions; all other methods are futile against prions.
How could prions multiply without nucleic acids?
Prions multiply by a process which is, at present, not fully understood. The protein PrPr is present in healthy cells of all mammals, in the brain and central nervous system. It is only when the gene that creates PrPr undergoes mutation that it begins to produce a harmful strain of PrPr, the prion. Prions replicate by causing the surrounding healthy proteins to fold abronmally, turning them into prions. These newly-formed prions in turn cause other proteins to fold abnormally. This process creates vacuoles in the cells of the brain, resulting in diseases such as Creutzfeld-Jakob disease in humans, and Bovine Spongiform Enphysema in cows.

Is the flu a noninfectious diseases?
Influenza is a highly infectious disease, even when the patient is recovering (unlike many other Infectious Diseases which quit being infectious when the patient begins to recover).

What are the differences between infectious and non-infectious diseases?
An "infectious disease" an agent that can be passed from one living organism to another. A non-infectious disease is a disease or other condition that cannot be spread to another organism.
What is the meaning of infectious disease?
The disease which is spread from person to person is called infectious disease. For example flu is a viral disease through which the other person is infected from the patient
Is asthma an infectious disease caused by a bacteria that causes inflammation and calcification in the lungs?
Asthma is not infectious disease. It does not spread from one person to other person.
Is lead poisoning a infectious disease?
No. You can not infect other people with it.
Can Alzheimer's disease result to other diseases?
no.Neither is it infectious.
How is an infectious disease different from an noninfectious disease?
Infectious diseases involve a causative organism, from groups such as bacteria, viruses, fungi, and such. Noninfectious diseases involve causes other than specific infectious organisms.
What kills more adults that any other infectious disease?
cigarettes
What does an infectious disease doctor do?
Infectious disease doctors are internal medicine doctors who treat and diagnose infectious diseases of varying types in the human body. Some diseases that infectious disease doctors deal with include AIDS, tuberculosis, malaria, meningitis, tetanus, and various infections of the respiratory system. Infectious disease doctors also aid in the prevention of tropical and other travel-related diseases.
Is H1N1 influenza infectious or non-infectious?
Influenza is a highly infectious disease, even when the patient is recovering (unlike many other Infectious Diseases which quit being infectious when the patient begins to recover).
