Allergies result when allergens bind to IgE molecules that are already bound to mast cells and basophils. It causes the sensitized cells to degranulate and release histamines. As a result, it produces localized allergic reactions with clinical syndromes. The symptoms include hay fever, asthma and urticarial. Antihistamines are administered for asthma patients. In systemic allergic reactions, anaphylactic shock may occur. The specific treatment for anaphylaxis is epinephrine.<br \/>\n<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/farm2.staticflickr.com\/1740\/42355455002_62ebf114d7_o.png\" alt=\"microbiology-with-diseases-by-taxonomy-chapter-18-answers-1cm\" width=\"552\" height=\"505\" \/><br \/>\n<a title=\"microbiology-with-diseases-by-taxonomy-chapter-18-answers-1cm1\" href=\"https:\/\/www.flickr.com\/photos\/155254960@N03\/42355454902\/in\/dateposted-public\/\" data-flickr-embed=\"true\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/farm1.staticflickr.com\/882\/42355454902_18076b14a9_o.png\" alt=\"microbiology-with-diseases-by-taxonomy-chapter-18-answers-1cm1\" width=\"570\" height=\"438\" \/><\/a><\/p>\n<p><span style=\"color: #339966;\"><strong>Microbiology with Diseases by Taxonomy Chapter 18 Answers 1CT<\/strong><\/span><br \/>\n<strong>The advantages of an individual that gain in making class E antibodies (IgE):<\/strong><br \/>\n<strong>Explanation<\/strong><br \/>\nIgE antibodies provide immunity against parasitic worms and protozoan parasite. Moreover, an allergen that triggers to IgE antibodies attaches to antigen binding sites. In addition, IgE antibodies are present on the mast cells and basophils, producing histamines and release into neighborhood.<br \/>\nTherefore, people exposed to internal parasites benefit from IgE antibody production. In rarely infected person, IgE antibodies are produced at low levels, in blood serum.<\/p>\n<p><span style=\"color: #339966;\"><strong>Microbiology with Diseases by Taxonomy Chapter 18 Answers 1L<\/strong><\/span><br \/>\nGraft types are named according to the relation between donor and the recipient. A graft is called an autograft when tissues are moved to a different location, within the same individual. A best example for autograft includes grafting of skin from one area of the body to another to cover a burns (or) use of a leg vein to bypass blocked coronary arteries.<br \/>\nIsografts are grafts transplanted between genetically identical individuals like siblings (or) clones. The MHC proteins are identical in these individuals. Thus Isografts are not rejected since they do not trigger immune response.<br \/>\nAllografts are grafts transplanted between genetically distinct members of the same species. The MHC proteins are not same in donor and recipient, it triggers strong type IV hypersensitivity reaction, which results in graft rejection.<br \/>\nXenografts are grafts transplanted between individuals of different species. Since, the tissues of donor and recipient are extremely different, they trigger a rapid and intense rejection of graft, which is very difficult to suppress. Transplanting a baboon\u2019s heart into a human is an example of xenograft.<\/p>\n<ol>\n<li>Autograft<\/li>\n<li>Isograft<\/li>\n<li>Allograft<\/li>\n<li>Xenograft<\/li>\n<\/ol>\n<p><span style=\"color: #339966;\"><strong>Microbiology with Diseases by Taxonomy Chapter 18 Answers 1M<\/strong><\/span><br \/>\nInflammatory mediators released from degranulating mast cells in <strong>type I hypersensitivity<\/strong> reaction causes allergies.

Thus, it could be ascertained that <strong>acute anaphylaxis<\/strong> could be associated with <strong>type I hypersensitivity<\/strong>. Hence, the given immune system complication matches with the option- <strong>A.

It plays a major role in mucosal immunity. It does not mediate type-I hypersensitivity. Hence, the option (a) is incorrect.<br \/>\nImmunoglobin M or (IgM) is the first antibody to appear in the primary immune response. It is commonly called natural antibody because it is formed in the blood even before primary immune response. It does not mediate type- I hypersensitivity. Hence, the option (b) is incorrect.<\/li>\n<li>Immunoglobin G or (IgG) is the only immunoglobulin that crosses the human placenta and thus offers a passive protection to the newborn babies for about 6-9 months. IgG neutralizes toxins and viruses. IgG binds to bacteria, opsonizes them, thereby enhance their phagocytosis and elimination. It provides humoral immunity. It does not mediate type-I hypersensitivity. Hence, option (c) is incorrect.<\/li>\n<li>Immunoglobin D or (IgD) has not been shown to have antibody activity and it does not mediate any functions attributed to immunoglobulins. IgD binds to basophils and mast cells and activates them to secrete antimicrobial factors to participate in respiratory immune defense. It does not mediate anaphylactic reaction. Hence, the option (d) is incorrect.<\/li>\n<li>Immunoglobin E or (IgE) -antigen interaction on mast cells results in degranulation of the mast cells and inflammatory mediators are released. Histamines, kinens, proteases, leukotrienes, prostaglandins are the inflammatory mediators that triggers type I hypersensitivity reactions. IgE provides immunity against worms, protozoan parasites.

It is a delayed type hypersensitivity reaction in which the skin of an individual is exposed to tuberculosis. Moreover, reacts to subcutaneous injection of a protein solution obtained from Mycobacterium tuberculosis. The resulting cell-mediated immune response generates memory T cells that persist in the body. However, other bacteria have unique antigens that trigger type IV hypersensitivity reactions. Immune responses to most of the bacterial infections are antibody mediated. Hence, physicians do not use skin tests to diagnose bacterial diseases.<\/p>\n<p><span style=\"color: #339966;\"><strong>Microbiology with Diseases by Taxonomy Chapter 18 Answers 2M<\/strong><\/span><br \/>\n<strong>Allergic contact dermatitis<\/strong> is a good example of <strong>type IV hypersensitivity reaction<\/strong>, which is T-cell mediated damage to chemically modified skin cells. The oil of poisonous ivy and related plants when rubbed against the skin, triggers cell-mediated immune response and results in intensely irritating skin rash called allergic contact dermatitis. Thus, it could be ascertained that allergic contact dermatitis could be associated with type IV hypersensitivity.<br \/>\nHence, the given immune system complication matches with the option <strong>D.

They are small molecules related to the amino acid histidine. Allergen binds to IgE molecule on sensitized mast cell. This binding triggers the sensitized mast cells to release the inflammatory chemicals. Inflammatory mediators mainly histamines are released from degranulated mast cells in type I hypersensitivity. Hence, the correct option is <strong>(c) histamine<\/strong>.<\/li>\n<li>Immunoglobulins are glycoproteins formed in response to an antigen and react specifically with that antigen. It is not an inflammatory mediator released by degranulating mast cells in type I hypersensitivity.

They are not mediators that cause allergic reaction. Hence, the option (b) is incorrect.<\/li>\n<li>Interleukin are not the inflammatory mediators released by degranulating mast cells. They do not cause type anaphylactic or type I hypersensitivity. Hence, the option (d) is incorrect.<\/li>\n<li>Prostaglandins are produced when allergens bind to IgE on mast cell, which activates other enzymes that trigger the production of leukotrienes and prostaglandis. They are not the major mediator released by degranulating mast cells in type I hypersensitivity.

If an Rh-positive blood group woman is carrying an Rh-ve (negative) fetus, the fetus doesn\u2019t have the risk of new born hemolytic disease, in which no antibodies are produced which destroys the fetus\u2019s red blood cells.<\/p>\n<p><span style=\"color: #339966;\"><strong>Microbiology with Diseases by Taxonomy Chapter 18 Answers 3CT<\/strong><\/span><br \/>\n<strong>Clinical consequences of autoimmune response to estrogen receptors:<\/strong><br \/>\n<strong>Explanation<\/strong><br \/>\nSystemic consequences are resulted when an autoimmune response is bound to estrogen. This is due to the presence of different cells producing estrogen receptors. There is reduction in fertility when any damage occurs to ovaries. Moreover, there is alteration in <a href=\"https:\/\/www.aplustopper.com\/menstrual-cycle\/\">menstrual cycle<\/a> in damaging the cells of endometrial. Since, the cells are involved in the growth of bone, which consists of receptors for estrogen there is impairment in remodeling.<br \/>\nFurthermore, the estrogen receptors in hypothalamus are targeted with high diversity and are not protected by blood-brain barrier. However, hypothalamus controls the regulation of endocrine functions. Thus, the estrogen receptors are targeted by an immune response that supports in fighting against estrogen-responsive cancers.<\/p>\n<p><span style=\"color: #339966;\"><strong>Microbiology with Diseases by Taxonomy Chapter 18 Answers 3M<\/strong><\/span><br \/>\n<strong>Systemic lupus erythematosus<\/strong> is an immune complex-mediated hypersensitivity reaction. It is a good example of <strong>type III hypersensitivity<\/strong> disease that affects multiple organs. Patients with generalized immunological disorder make antibodies against numerous self-antigens found in normal organs and tissues, giving rise to many different pathological lesions and clinical manifestations.<br \/>\nDevelopment of self-reactive antibodies called autoantibodies bind to many autoantigens, especially the patient\u2019s DNA (deoxyribonucleic acid). Thus, it could be ascertained that systemic lupus erythematosus could be associated with type III hypersensitivity.<br \/>\nHence, the given immune system complication matches with the option <strong>C.

High levels of IgE are produced in only some allergic individuals. The main reason is exposure to environmental factors during infancy and childhood to high levels of indoor antigens such as cigarette smoke, dust mites, and molds. Hence, the sensitized individuals become hypersensitive.<br \/>\nEveryone is exposed to antigens in the environment, which triggers an immune response resulting in the production of IgG. But when cytokines from type II helper T lymphocytes activate the B lymphocytes in allergic persons, the B lymphocytes become turned into plasma cells, switches to IgE instead of producing IgG.<br \/>\nFollowing a sensitized individual\u2019s contact with an allergen, many mast cells may degranulate simultaneously, releasing massive amounts of histamine and other inflammatory mediators into the bloodstream. The release of chemicals may exceed the body\u2019s ability to adjust, resulting in anaphylactic shock.<\/p>\n<p><span style=\"color: #339966;\"><strong>Microbiology with Diseases by Taxonomy Chapter 18 Answers 4CT<\/strong><\/span><br \/>\n<strong>Defects in B-cells produce bacterial infections, while defects in T-cells produce viral disease:<\/strong><br \/>\n<strong>Explanation<\/strong><br \/>\nAntibody-mediated responses with extracellular bacteria are effective in fighting against bacterial infections.

The four classes of immunosuppressive drugs include glucocorticoids, cytotoxic drugs, cyclosporine, and lymphocyte-depleting therapies.<\/p>\n<ol>\n<li>Glucocorticoids are corticosteroids, used as immunosuppressive agents for many years. Prednisone and methyl prednisolone are examples of glucocorticoids. The drugs suppress the response of T cells to antigen and inhibit T cell cytotoxicity and mechanism of cytokine production.<\/li>\n<li>Cytotoxic drugs inhibit cell division nonspecifically. Cyclophosphamide, azathioprine, mycophenolate mofetil, brequinar sodium, and leflunomide are examples of cytotoxic drugs. Cyclophosphamides cross-link daughter DNA molecules in mitotic cells, preventing their separation and blocking mitosis. It impairs both B cell and T cell responses.<\/li>\n<li>Azathioprine is a purine analog, which competes with purines during the synthesis of nucleic acids. Thus, blocks DNA replication and suppressing both primary and secondary antibody responses. Mycophenolate mofetil is a cytotoxic drug, which inhibits purine synthesis. Brequinar sodium and leflunomide inhibits pyrimidine synthesis to inhibit cellular replication.<\/li>\n<li>Cyclosporine drug is a polypeptide derived from fungi, preventing interleukins and interferon produced by T cells, thereby blocking Th1 responses. Cyclosporine acts on activated T cells. It is less toxic than the other nonspecific drugs. When the drug is given to prevent allograft rejection, only activated T cells attack the graft are suppressed.<\/li>\n<li>Lymphocyte-depleting therapies are used to reduce the adverse side effects of less specific immunosuppressive drugs. One of the techniques includes administering an antiserum called antilympocyte globulin, which is specific for lymphocytes. The modes of action of the therapies are, kills T cells nonspecifically, kills activated T cells, and IL-2 receptors are inhibited.<\/li>\n<\/ol>\n<p><span style=\"color: #339966;\"><strong>Microbiology with Diseases by Taxonomy Chapter 18 Answers 6CT<\/strong><\/span><br \/>\n<strong>Illnesses that cause death in patients when combines with AIDS:<\/strong><br \/>\n<strong>Explanation<\/strong><br \/>\nTissues are different in pigs and humans where matching of tissue is not possible in xenografts.

The class I and II MHC proteins are involved in the graft versus host rejection.<br \/>\nWhen graft (donated) bone marrow T cells may consider the patient\u2019s cells as foreign, mounting an immunological graft rejection against the recipient. It is a good example of type IV hypersensitivity. Thus it could be ascertained that graft-versus-host disease could be associated with type IV hypersensitivity.<br \/>\n<strong>6.<\/strong> Graft-versus-host disease <strong>(d) Type IV hypersensitivity<\/strong>.<\/p>\n<p><span style=\"color: #339966;\"><strong>Microbiology with Diseases by Taxonomy Chapter 18 Answers 6MC<\/strong><\/span><\/p>\n<ul>\n<li>Systemic lupus erythematosus is a systemic autoimmune disease that affects multiple organs. It is also a type III hypersensitivity in which autoantibodies bind to many autoantigens, especially to the patient\u2019s DNA. Hence, the correct option is <strong>(e) Systemic lupus erythematosus<\/strong>.<\/li>\n<li>Autoimmune disease is production of autoantibodies or cytotoxic T cells against normal body components. Heart attack is not an autoimmune disease; it is caused mainly due to blockage in arteries. Hence, the option (a) is incorrect.<\/li>\n<li>Acute anaphylaxis is caused when massive amounts of histamine are released from degranulating mast cells into the bloodstream. The result of chemicals may exceed the body\u2019s ability to adjust. Autoantibodies ate not produced against normal body components in acute anaphylaxis. Hence, the option (b) is incorrect.<\/li>\n<li>Farmer\u2019s lung is one form of hypersensitivity pneumonitis, caused when immune complexes are deposited in the lung. It is a type III hypersensitivity reaction. It is different from autoimmune disease. Hence, the option (c) is incorrect.<\/li>\n<li>Graft-versus-host rejection is transplantation of an organ or tissue from a donor to a recipient, in which, the donor tissues are considered as foreign, an immune response against them is elicited and the graft will be rejected. Hence, the option (d) is incorrect.<\/li>\n<\/ul>\n<p><span style=\"color: #339966;\"><strong>Microbiology with Diseases by Taxonomy Chapter 18 Answers 7CT<\/strong><\/span><br \/>\n<strong>Blisters of tuberculin reactions resemble blisters of ivy poison:<\/strong><br \/>\n<strong>Explanation<\/strong><br \/>\nTuberculin skin test and oil of poisonous ivy comes under type IV or delayed type hypersensitivity reaction. They both trigger cell-mediated immune response. Tuberculin is mediated by the response of memory T cells. Additionally, an individual is infected with Mycobacterium tuberculosis, results in cell-mediated immune response to generate memory T cells. In tuberculin test, red, hard swelling, and inflammation reaches greater intensity within 24-72 hours. When the lesions developed are examined microscopically, it reveals infiltration of lymphocytes and macrophages.<br \/>\nFurthermore, oil of poisonous ivy is a highly reactive hapten that binds to any protein it contacts. It includes the proteins in the skin when anyone rubs the plant. The chemically modified skin protein is regarded as foreign, triggering a cell-mediated immune response, and resulting in an intensely irritating skin rash called allergic contact dermatitis. Thus, Tc cells destroy skin cells that become acellular, and fluid-filled blisters develop.<\/p>\n<p><span style=\"color: #339966;\"><strong>Microbiology with Diseases by Taxonomy Chapter 18 Answers 7M<\/strong><\/span><br \/>\nMilk allergy is caused due to adverse reaction, because of different biochemical constituents of the milk from any lactating animal.

The type I hypersensitivity occurs due to the allergens binds on IgE antibodies that coated on the mast cells and eosinophils.<br \/>\nUpon binding of allergens to the IgE antibodies on the mast cells causes the release of the histamines. These histamines are mainly, responsible for the allergic responses of an individual.<br \/>\nIt is a potentially life-threatening condition. Thus it could be ascertained that milk allergy could be associated with type I hypersensitivity.<br \/>\n<strong>7.<\/strong> Milk allergy <strong>(a) Type I hypersensitivity<\/strong>.<\/p>\n<p><span style=\"color: #339966;\"><strong>Microbiology with Diseases by Taxonomy Chapter 18 Answers 7MC<\/strong><\/span><\/p>\n<ul>\n<li>A graft is called an auto-graft when tissues are moved to a different location within the same individual. It will not trigger immune response because they do not express foreign antigens. Thus, when a piece of vein from a patient\u2019s leg is transplanted to the same patient\u2019s heart, it is said to be as auto-graft. Hence, the correct option is <strong>(b) an autograft<\/strong>.<\/li>\n<li>Graft rejection is transplanting an organ or tissue from a donor to a recipient, in which the donor tissues are considered as foreign, an immune response against them is elicited and the graft will be rejected. By transferring a piece of vein from a patient\u2019s leg to the same patient\u2019s heart, the graft will not be rejected. Hence, option (a) is incorrect.<\/li>\n<li>Allografts are grafts transplanted between genetically distinct members of the same species. Allografts typically induce type IV hypersensitivity reaction, resulting in graft rejection. Hence, option (c) is incorrect.<\/li>\n<li>Type IV hypersensitivity reaction is also known as delayed hypersensitivity reaction in which T cell-mediated inflammatory reaction takes 24-72 hours to reach maximal intensity. It induces immune response, whereas autograft do not trigger immune response. Hence, option (d) is incorrect.<\/li>\n<li>When cardiac operation is done for transplanting a piece of vein from a patient\u2019s leg to the same patient\u2019s heart it is called autograft. This will not trigger any immune response. The term cardiograft is not used in this condition.

The disease is characterized by wheezing, coughing, excessive production of a thick, sticky mucus, and muscle constriction in bronchi. Asthma is life threatening, which causes suffocation. Thus it could be ascertained that asthma could be associated with type I hypersensitivity.<br \/>\nThe type I hypersensitivity is mainly due to the exposure to an allergen. The type I reaction occurred mainly due to release of the histamines, by the mast cells.
