  1. 2. An invasive method of urine collection using a tube inserted into the bladder.
  2. 4. Media that distinguishes bacteria based on visible differences (like color changes).
  3. 6. A technique using fluorescent antibodies to detect specific antigens under a microscope.
  4. 8. A technique that amplifies DNA or RNA to detect even small amounts of a pathogen.
  5. 9. A selective and differential medium that grows Gram-negative bacteria and shows lactose fermentation.
  6. 12. A highly specific test used to confirm the presence of certain proteins (like HIV antibodies).
  7. 14. A urine collection method that reduces contamination by cleaning the genital area first.
  8. 17. An enriched and differential medium used to grow many bacteria and observe hemolysis.
  9. 18. The breakdown of red blood cells, used to differentiate bacteria on blood agar.
  10. 19. A highly invasive method where a needle is used to collect urine directly from the bladder.

  1. 1. A test that determines antibiotic susceptibility using disks on an agar plate.
  2. 3. A method used to prevent contamination by keeping everything sterile during sample collection.
  3. 5. Microorganisms that naturally live on or in the body and usually do not cause disease.
  4. 7. A test used to detect either antigens or antibodies using enzyme-linked reactions.
  5. 10. A molecule from a pathogen that triggers an immune response.
  6. 11. The unwanted presence of microbes that can alter test results.
  7. 13. A staining technique that differentiates bacteria into Gram-positive or Gram-negative.
  8. 14. A measure of viable bacterial cells; used to estimate infection severity.
  9. 15. Media that allows only certain types of microbes to grow.
  10. 16. Testing body fluids (like blood serum) for antibodies or antigens.
