Medical Microbiology BIO 232 Lecture Pre-Test Unit II Short Answer and Fill-In
| 1 | Parasite |
| 2 | symbiosis |
| 3 | infectivity invasiveness toxogenicity pathogenicity |
| 4 | amphibiont |
| 5 | opportunist organism |
| 6 | infection |
| 7 | pathogenicity toxogenicity |
| 8 | Clostridium perfringens - causes gas
gangrene Clostridium tetani- causes tetanus |
| 9 | Salmonella typhosa- cause of
intestinal disease Shigella dysenteriae - cause of severe dysentery |
| 10 | exotoxins |
| 11 | kinase - fibrinolysin |
| 12 | a). hyaluronic acid-
Streptococcus pyogenes b). M protein - Streptococcus pyogenes |
| 13 | a). minimally - 2 hours b). 48 hours - 2 days |
| 14 | mucus membrane - produces mucus phagocytosis inflammation reaction fever ciliary function |
| 15 | pores in the skin eg. ducts of sweat glands and hair follicles |
| 16 | lysozyme - digests the polysaccharides
in the bacterial cell wall fatty acid - creates an acid pH |
| 17 | polysaccharide in the bacterial cell wall |
| 18 | mucus- sticky and traps microbes cilia - force microbes to the Portal of Entry neutrophils - white blood cells which phagocytize microbes lysozyme - digest the polysaccharide in bacterial cell walls |
| 19 | decreases mucus production by the goblet cells |
| 20 | impairs ciliary function |
| 21 | botulinum |
| 22 | saliva - flushes microbes out of mouth stomach acid - inhibits or kills most microbes stomach proteolytic enzymes - digests microbial proteins to kill microbes small intestine proteolytic enzymes - digests microbial proteins to kill microbes |
| 23 | has mucus to trap microbes has cilia and neutrophils in its lining tissue hair in nostrils - helps filter germs cough reflex in respiratory tract flush germs out of body by coughing them out |
| 24 | birth control pill |
| 25 | lymph nodes spleen liver lung red bone marrow |
| 26 | local lymph nodes |
| 27 | mobile phagocytic cells - ( neutrophils
and monocytes ) - phagocytize microbes reticuendothelial cells ( immobile phagocytes) - phagocytize and kill microbes |
| 28 | opsonin |
| 29 | histamine |
| 30 | neutrophils |
| 31 | monocyte |
| 32 | hypothalamus |
| 33 | leucocytic extract - tissue
prostaglandin endotoxin - lipopolysaccharide produced by gram (-) bacteria |
| 34 | kills germs increases antibody production increases the phagocytic response makes us aware of infectious disease |
| 35 | substance called tissue prostaglandin which interacts
with the hypothalamus to cause a higher body temperature- raises temperature set point |
| 36 | kinase - dissolves clotted blood coagulase - converts fibrinogen to fibrin collagenase - digests collagen in connective tissue M protein - antiphagocytic surface chemical |
