  1. 2. Pathogenic flagellated protozoan with unique symmetrical heart shape; surface is concave and acts like a suction cup; contains four nuclei.
  2. 3. Severe forms can include elevated body temperature and septicemia.
  3. 4. One of the most common bacterial causes of diarrhea in the U.S. Harmful bacteria originating from food.
  4. 5. Protective function of the GI tract; ie. E. coli fights off Salmonella in healthy individuals.
  5. 7. Tooth Decay: the most common infectious disease of human beings. Involves the dissolution of solid tooth surface due to the metabolic action of bacteria.
  6. 8. GI diseases include roundworms, tapeworms, and Eosiniphilia.
  7. 10. RNA virus sometimes called the silent epidemic. Takes many years to produce noticeable symptoms.
  8. 12. Strain of Campylobacter that is common bacterial cause of foodborne illness. Spiral gram negative bacteria, propelled by flagella, inhabitants of GI tract.
  9. 13. RNA virus transmitted through the fecal-oral route; unhygenic food handling.

  3. 6. Mutans was thought to be the singular cause of tooth decay. Gram-positive alpha hemolytic. Often caused by multiple bacteria contributing destructive acid production.
  4. 8. DNA virus; Infectious virions called Dane particles, but other noninfectious morphologies exist.
  5. 9. Shiga-Toxin-Producing E. coli; Exotoxin identical to the Shiga exotoxin secreted by virulent Shigella bacteria.
  6. 11. Cholerae Gram negative rods with a flagellum; Shares many characteristics with Enterobacteriaceae family.
