Summary Introduction
Introduction:
A patient’s serum, Chlamydia, guinea pig complement, sheep red blood cells and anti-sheep red blood cells are mixed in a tube. No hemolysis occurs, when the patient has antibodies against the Chlamydia. This gives the ocular infections in guinea pig.

- Explain how the pathogenesis of Epstein-Barr virus (EBV) leads to the presence of heterophile antibodies in the patient’s blood.arrow_forwardA male college freshman is seen at the college health service complaining of general fatigue, a sore throat, and swollen lymph nodes in his neck. A throat culture is done, and blood is drawn for hematology studies and a rapid MonoSlide test. Hematology results show a normal hemoglobin value and a slight increase in the white cell count, with many large, reactive lymphocytes seen in the differential. A rapid strep test is negative, but a second swab is cultured on sheep blood and incubated, with the result to be read in 18 hours. Result from the MonoSlide test is positive.

Why did the patient have an increased white blood count with abnormal appearing lymphocytes?arrow_forwardApply your knowledge: 1) A patient with B+ blood will have B and Rh Antigen. How about A-, AB+,0-? 2) A patient with B+ blood will have anti-A in the Plasma. How about A-, AB+, 0-? 3) Blood type that does not have antigens on the surface do not have antigens for antibodies to bind to. This blood type is the universal donor. Which blood does not have surface antigen and is the universal donor? 4) Blood type that has all the antigens do not make antibodies in their plasma. This type of blood does not have antibodies to bind to blood. This blood type is the universal recipient. Which blood type does not have antibodies and is the universal recipient? 18-14arrow_forward
