Across

  1. A substance that reacts with antibody molecules and antigen receptors on lymphocytes.
  2. A presumptive screening test for syphilis looking for non-treponemal anti-lipid (reagin) antibodies in the patient's serum. (acronym)

  11. An autoimmune disease that cqan follow infections by group A beta streptococcus. (2 words)
  12. Serologic testing by which antibodies in a person's serum being made by that individual against an antigen associated with a particular disease are detected using a known antigen.
  13. An estimated 0.5-1.0% of neonates colonized will develop pneumonia, septicemia, and/or meningitis from this streptococcus.
  14. Using antigen-antibody reactions in the laboratory for diagnostic purposes.
  15. Hemolysis showing , red blood cell-free zone surrounding the colony, where a complete lysis of the red blood cells by the bacterial hemolysins has occurred.
  16. A serologic test that only detects the presence or absence of specific antibodies in the patient's serum and is often used for screening purposes.

  18. In the serological testing for pregnancy we look to see if the woman is producing _____. (acronym)
  19. The most dilute sample of the patient's serum still containing enough antibodies to give a visible antigen-antibody reaction is reported as the titer.
  20. An infected hair follicle where the base of the hair follicle appears red and raised with an accumulation of pus just under the epidermis.

Down

  1. The common name for this gram-positive diplococcus that is the most common cause of community-acquired pneumonia requiring hospitalization, and is a frequent cause of otitis media, sinusitis, and bacteremia.
