- Compare and contrast Radial Immunodiffusion with it’s close relative, the Ouchterlony plate technique. How are they similar and how are they different?Why do the ring sizes change until equivalence is reached in radial immunodiffusion?Candida Albicans may cause minor infections in healthy people,but causes dangerous infections in immunocompromisedpatients. Why?
- Part A) What barrier was breached by the pathogen? Part B) Describe how that barrier works and how it can prevent mom's pathogens from infecting the fetus. A tiny 1-kg (2.2-pound) female neonate (newborn) was born two months premature. The baby had extreme difficulty breathing and had to be intubated (a breathing tube inserted). The mother, at the time of admission, had complained of mild diarrhea and abnormal abdominal pain unrelated to her pregnancy. The infectious disease doctor who was called in to consult on the case immediately recognized the likely problem and ordered blood cultures be performed on the infant. The infant was also started on intravenous antibiotics. Two days later, the lab reported finding a Gram-positive bacillus-Listeria monocytogenes-in the infant's blood. This same organism was the cause of the mother's diarrhea. The mother had unwittingly ingested some unpasteurized cheese contaminated with this pathogen and developed listeriosis. The organism entered the…What component must have been present in the positive control solution (antigen, anti-HIV IgG antibodies, or secondary antibody)? Explain how you know this is true.(56) A 1 year old boy dies of staphylococcal pneumonia. He has had multiple skin infections since birth. Separation of the umbilical cord was delayed. A skin window test was performed and no leukocyte accumulated on the cover ship. The cytometric analysis showed that only 5% of the T lymphocytes reacted with a monoclonal antibody to leukocyte functional antigen-1 chain (CD 18) compared with reactivity of 62 % for a normal subject. Just prior to death, his leukocyte count was 75,000/mm3. Which of the following is the most likely diagnosis? (A) AIDS (B) Cogenital Asplenia (C)Leukocyte Adhesion Deficiency (D) Severe Combined Immunodeficiency Disease (E) X linked agammaglobulinemia
- The TB skin test is usually negative in AIDS patients. Why?Encapsulated organisms can be phagocytized once antibodies against the capsule have been produced.

- DescrAnaphylactic shock is seen a person who produced a large amount of IgE than the person who produced IgG.A patient came to the health center have recurring fever, unexplained tiredness, and prolonged swelling of the lymph glands. Also, the patient’s CD4 count is less than 200 cell/mm3. Identify the organism that cause the condition also explain how you come up with the diagnosis? Provide reason why CD4 cell were affected. Give the scheme of test you would run to confirm the pathogen?1) SDS PAGE gels can be probed with NBT/BCIP to perform an immunoblot true/ false 2) the direction of migration of protiens through a matrix is due to most proteins in natur having a net negative charge true/false 3) PBST is a buffer that is used for blocking the membrane during immunoblotting. true/false 4) the buffer used during for transferring proteins to nitrocellulose methanol. true/false 7) The size of the pores of a polyacrylamide gel dcreases as concentrations of polyacrylamide increases. True or false 10) The secondary antibody used in laboratory for western blotting is conjugated to which enzyme A) Alkaline decarboxylase B) GAPDH C) Alkaline Phosphatase D) Horseeradish peroxide 13) In protien electrophroresis, what reagent present in the sample buffer is used to eliminate difference in the charge densities of protein A) SDS B) 2- mercaptoethanol C) Tris-HCL pH6.8 D) Tris- HCL PH 8.8
