  1. 1. a coating found throughout the surfaces of the GI tracts (an innate defense)
  2. 4. (abbreviated for Hep A Virus) RNA virus transmitted through fecal oral route by unhygienic food handling
  3. 5. pathogenic flagellated protozoan (heart shaped with flagella); resembles a face with suction cup and has four nuclei. Diarrhea and flatulence, greasy, foul-smelling stools
  4. 7. (abbreviated for gut associated lymphoid tissue) an adaptive defense. Packets of lymphoid tissue consisting of T and B cells, tonsils, esophagus, Peyer’s patches in small intestine, appendix
  5. 8. (two words; Gram+ endospore forming rod; has flagella) normal microbe of intestine that capitalizes on weak immune system or gut microbiome change. Has Enterotoxins A and B that causes necrosis in the walls of the large intestine (colon)
  6. 10. (abbreviated for Hep C Virus) RNA virus. silent epidemic. Liver failure. Transmitted IV drug use and rarely blood transfusions
  7. 11. (Salmonella enterica; gram- and have flagella) normal intestinal biota in cattle, poultry, rodents, and reptiles. Adheres to gut mucus membrane and releases endotoxin. May lead to increase temp and septicemia
  8. 12. (jejuni; gram- spiral with flagella) most common during summer months with outdoor grilling. Burrows through mucus and multiplies in the small intestine
  9. 13. found in saliva and eyes (an innate defense)
  10. 14. inflammation disease of the liver is marked by necrosis of hepatocytes. Also causes Jaundice caused by bilirubin accumilation
Down
  1. 2. (two words) exotoxin produced by E. coli through a gene acquired by transduction. Has ability to destroy cells in large intestine (bloody diarrhea)
  2. 3. (two words Gram- rods with flagellum) resembles a comma; transmission from flooding, disruption of sanitary systems, warm temps.
  3. 4. (worms) parasite to humans. Destroyed by eosinophils (WBC). Fecal oral route of transmission or penetrating the skin
  4. 6. muscular walls of GI tract keep food and microorganism moving (an innate defense)
  5. 9. (two words) tooth decay caused by Streptococcus mutans (alpha hemolytic, gram+) and Lactobaccillus
  6. 14. (abbreviated for Hep B Virus) DNA virus. Leads to liver cancer. Infectious virions called Dane Particles. Transmitted via needle sticks and blood. There is a vaccine.
