What is the relationship between pathogens and infectious diseases?
Why cant people just look it up instead of sittin around waiting for other people to answer it. someone be the first to answer it look it up in every book you can find geeze people thats why i never use this website
How are respiratory pathogens mostly spread?
Airborne is the #1 way it is spread along with contact. If an infected individual coughs into their hand and touches something and then you touch it.....but by domeone coughing without covering their mouth can send infected particles into the air and can be ingested by another individual. These particles can be sent several feet away when an individual coughs without covering their mouth.
Which body sytems does not work with the immune system to regulate internal body functions?
The digestive system does not work with the immune system to regulate body functions.
Is the best definition of epitope?
The immune cells do not recognize an entire immunogen molecule, instead the lymphocytes recognize the unique individual chemical groups or discrete & specific sites having three-dimensional shape on the macromolecules, called epitopes.
What did Edward Jenner discover and when?
Edward Jenner became a doctor because after training in London as an army surgeon, spent his whole career as a country doctor in his native county of Gloucestershire in the West of England. His research was based on careful case-studies and clinical observation before scientist could explain the virus themselves.
Is immunization an example of primary prevention?
Yes, Immunization is a form of primary prevention as it prevents the onset of a disease/disease process
How are allergens and antigens similar?
Antibodies (Abs), T cell receptors (TCRs) and MHC molecules are all involved in the adaptive immune response. All 3 of these (Abs, TCRs and MHCs) have a range of diversity of structure and are composed of different chains.
In most animals (including humans) antibodies are composed of 2 heavy chains and 2 light chains, each of which has constant and variable regions. This is very similar to a T cell receptor, which is composed of an α (alpha) and β (beta) chain - which have a contant and variable region.
In both cases, it is the variable region(s) which determines what the antibody or the T cell receptor can bind to. This is very important for their function.
T cell receptors (TCRs) and antibodies (Abs) are also similar in that their genes are combined and spliced in different ways to create diversity. It is important that both TCRs and Abs be able to recognise may different things.
MHC molecules are responsible for presenting antigens to T cell receptors. Once again, they are composed of an α (alpha) and β (beta) chain, which are different depending on whether they are MHC I or MHC II.
What are the four main groups of pathogens?
Haemophilus influenza
Moraxella catharralis
Streptococcus pneumoniae
Staphyloccus aureus
up for discussion
Streptococcus pyogenes
Influenza virus A B and C
The binding of an antigen to an antibody can result in?
neutralization of the antigen, agglutination or precipitation, and complement activation.
zinc
What are the components of the second line of innate defenses?
there are 3 main component of immunity which helps to maintain the innate immunity. these are-
1. anatomical barrier such as skin, mucosal membrane, conjuntiva
2. physiological barrier such as fever, Ph, oxygen tension etcf.
3. phagocytosis which is performed by W.B.C.
Why do antibodies not work on flu?
Assuming the question is a typo for "Why do antibiotics not work on a flu?", the reason is quite simple. Influenza (Flu) is caused by a virus, not a bacteria or parasite.
When you have an infection, and your doctor prescribes you antibiotics, they are working on a bacterial or parasitic infection, not a viral infection.
Put quite simply, antibiotics are not effective whatsoever against viruses.
How old was Edward Jenner when Edward he invented the vaccination?
This did not happen suddenly in a single year, nor was Jenner the first person to discover this or use vaccination.
English physician John Fewster had realized before 1768that prior infection with cowpox rendered a person immune to smallpox.
In the years following 1770, at least five investigators in England and Germany (Sevel, Jensen, Jesty 1774, Rendell, Plett 1791) successfully tested a cowpox vaccine in humans against smallpox. For example, Dorset farmer Benjamin Jesty successfully vaccinated and presumably induced immunity with cowpox in his wife and two children during a smallpox epidemic in 1774, but it was not until Jenner's work that the procedure became widely understood. Jenner may have been aware of Jesty's procedures and success.
On May 14, 1796, Jenner tested his hypothesis by vaccinating James Phipps, an eight-year-old boy who was the son of Jenner's gardener. Phipps was the 17th case described in Jenner's first paper on vaccination, clearly Jenner had performed vaccinations before vaccinating Phipps.
Is skin specific or nonspecific?
Yes, the skin is the most important nonspecific defense. This is because your oil and sweat glands are acidic.
What are the immune systems 3 lines of defense?
Line 1 - Non-specific: Barriers such as intact skin, natural flora, mucus membranes.
Line 2 - Non-specific: White blood cells such as Phagocytes (e.g. macrophages/dendritic cells), Inflammatory response, interferons.
Line 3 - Specific: White blood cells such as B and T cells and antigens.
What does it mean to have nonspecific innate immunity?
The cells of the innate system recognize and respond to the pathogens in a specific generic way.
How much time it takes to produce detectable antibodies in the blood during primary immune response?
In general, it takes approximately one week(or less than a week) for an adult to develop antibodies during primary immune response.
What is the role of antibodies in the body response to infection?
Antibodies are basically all the same except for a tip that recognizes the corresponding antigen. When the antibody finds this antigen it locks on and targets the virus.
How does the immune system fight cholera?
with white blood cells and antibodies. If you have it though, its probably because of drinking unclean water, you should go to the hospital right away
What are two ways that pathogenic organisms can cause infection and disease?
Two ways that pathogenic organisms can cause infection and disease is by producing poison and to attack and destroy the living cells they intrude.
