* AP IMMUNE SYSTEM * An animal must defend itself against unwelcome intruders -- the many potentially dangerous viruses‚ bacteria‚ and other pathogens it encounters in the air‚ in food‚ and in water. * Herpes simplex-1 (Herpes labialis‚ HSV-1) * Herpes simplex 2 (HSV-2‚ Herpes genitalis) on thigh * Three cooperative lines of defense have evolved to counter these threats. * Two of these are nonspecific -- that is‚ they do not distinguish one infectious agent from another

to death in three to five days. If this disease is left untreated it can be extremely deadly. However‚ if it is treated it often leads a person to full recovery and no further infections return. Some ways to treat the Bubonic Plague include using antibodies such as tetracycline or sulfonamide; these are commonly used as a precaution for people that could potentially be exposed to the bacteria. Vaccines are also available‚ however they are mostly reserved for people with a high risk of getting this

hearty laugh relieves physical tension and stress‚ leaving our muscles relaxed for up to 45 minutes after. Secondly‚ laughter boosts the immune system. When we laugh‚ it will decreases stress hormones and increases immune cells and infection-fighting antibodies‚ thus improving your resistance to disease. The other benefit is laughter triggers the release of endorphins. Endorphin is the body’s natural feel-good chemicals. It promotes an overall sense of well-being and can even temporarily relieve pain

does this mean for the rest of your results? A negative results with a positive control indicates a “false negative” and your results are invalidated. Direct Fluorescent Antibody Technique 4. Why is this technique a direct method? It is considered a direct method because it involves conjugation of an antibody with fluorescent dye. 5. What is an elementary body? An elementary body is an infectious particle of any of several microorganisms. 6. How do elementary bodies look under

information of various antigen-antibody tests eg. ASO‚ haemotoglutination‚ ELISA etc. Method: To listen to presentation made and thus formulate a concise report on that which was discussed and demonstrated. (Please see BC34D Laboratory Manual for more information) Concise Report/Summery: The term serology refers to both the study of general antigen-antibody reactions in a laboratory setting and the specific blood test conducted to test for the presence of antibodies. A serology test is performed

No I would have removed all the people and disinfected all of them so the virus would stay in the forest and nobody would die. 3. Sam Daniels and his crew were sent out to the Motaba Valley because there was a level 4 virus. 4. The conditions in the Motaba valley were sad‚ smoky‚ poor and there were dead people everywhere. 5. The symptoms of the mystery disease at Motaba Valley

foundational reaction in our Immune system; the Antigen-Antibody interactions. The Ouchterlony procedure is what will be used in this lab to detect nature of the antibody interaction. The orientations of the band will provide more information about the interaction of antibody and antigen. Hypothesis: For this experiment‚ antibodies will be placed in wells on an agar plate‚ surrounded by wells containing serum (proteins‚ antigens etc.). If the antibody interacts with the antigen of surrounding wells‚ then

by: Dipen Patel I. Objective: The purpose of the lab was to learn the procedure of performing an ELISA test to determine whether a particular antibody is present in a patient’s blood sample. ELISA is an abbreviation for “Enzyme-linked Immunosorbent Assay." II. Introduction: The interaction of antigen and antibody outside the body can be used to determine if patient has an infectious or an autoimmune disease. In this particular exercise‚ the sample blood is collected from three
