Summary Introduction
To evaluate:
The chances of developing diabetes in uncontrolled and controlled models of mice and draw conclusions supported by the data provided in the graphs.
Introduction:
The risk of developing type 1 diabetes by the mice is high due to affected parents. The two groups are taken and infected with Heligmosomoides polygyrus (Hp) to analyze the risk of developing the disease. Hp is a naturally occurring roundworm of rodents. It inhabits the intestinal tract of rodents. The graphs given below show the link between the infections caused by Hp and the percentage of the diabetic mice.

Consider that the Herd Immunity Threshold is dependent on the reproduction number for an infectious disease. The combination of herd immunity and quarantines were highly effective for eradicating smallpox. What is different about the symptoms of polio infection that makes quarantining infected individuals much more difficult?
In a case study, scientists frequently infer that Malignant transformation of hymenolepis nana in human host occurred because of the patient’s HIV/AIDS status and resultant immunocompromised state. When N=1, is such an inference statistically justified? In addition to Yes or No, jot down your thoughts on the possible association between AIDS and this case.

- Which of the following is NOT a mechanism used by the immune system to fight multicellular parasites? Select one: a. Antibodies coating the pathogen surface bind to FcRs on mast cells, causing release of granule contents onto surface, and damage the parasite. b. Crosslinking of antibody binding to FceRI on eosinophils cells triggers release of granules, causing smooth muscle contractions. Muscle contractions in the mucosal tracts causes sneezing, coughing, vomiting or diarrhea, dislodging the parasite. d. The parasite is killed and broken down extracellularly, and then phagocytosed by macrophages. C.arrow_forwardA pathogenesis function f(t)t(t-21)(t + 1) is used to model the development of the disease, where t is measured in days and f(t) represents the number of infected cells per mL of plasma.

Vaccines should be tested for long period of time before allowing any individual to take the vaccine. b. Vaccines take time to bedeveloped and studied for their effectivity and effects. C. All aspects as on the long term effects of vaccines, its effect on children, pregnant women, effect to reproductive system, immediate side effects and many more should be analysed first. . All vaccines have side effects, only few individuals should have them. d.
