| Question | |
|---|---|
| blood agar | differential media beta alpha gamma hemolysis |
| hemolysis | alpha partial growth beta growth and clearing gamma growth |
| catalase test | + bubbles turns hydrogen proxide into h2o & o2 |
| citrate utilization test | blue + green- differental media |
| EMB agar | selective differential gram- lactose ferment rods coliforms |
| IMViC | combine indole mrvp citrate distinguish enterobacteriaceae |
| MacConkey agar | selective differential gram- lactose ferment rods coliforms |
| mannitol salt | selective differenital stapyhlcocci grow s.aureus ferments |
| mueller-hinton agar | kirby baurer method zone of inhibition bigger better |
| MIO | motility indole production ornithine decarboxylation |
| MRVP | MR mixed acid fermentation yellow- red+ VP neutral acetoin butanediol red |
| OF media (glucose) | green- yellow+ w/oil anerobic w/o oil aerobe facultative both |
| Oxidase test | swap blue/purple positive no reaction negative |
| phenol red fermentation broth | yellow acid bubble gas bacis fusica nurtal red orange durham tube ph indicator |
| phenylalanine deamination test | amino acid test |
| strach agar | hydrolysis reation reagent iodine (to see reaction on agar) amylase is excenzyme |
| urea agar | urease red + fusica bacis yellow acidic nh3+co2 pink+ yellow peach- |
| acid fast | +fusica pink blue- mycobacteria |
| capsule | white halo around cell stain cell and background |
| endospore | +organisms bacillus clostridium |
| flagella | motile organisms |
| gram | purple + pink/red - |
| bile salt | inhibit growth of gram+ organisms |
| COLIFORMS | GRAM- LACTOSE FERMENTING ROD FACULTATIVE ANAEROBES(bacullius) ENTERICS USED TO DETECT FECAL CONTAMIATION(emb macconkey) |
| Colony | visible to maked eye on agar plate pure colony |
| dichotomous key | gram- and gram+ flowchart |
| differenital media | differentiate organismis by growth characteristics |
| Enterobacteriaceae/enterics | gram- facultatively anaerobic rod inhibit animal intestines |
| facultative anaerobe | can metabolize aerobically or anaerobically by fermination |
| fermantation | produces acid gas alcohol end products from carbohydrate hydrolysis |
| obligate aerobe | only metabolizes aerobcially of test w/o oil only |
| resolution | what u can see throught a microspoce clearly smaller resolution the better (think camera pixels) |
| selective media | inhibits growth of some organisms favor growth of others |
| streak plate | method for pure colonies...0 1 2 3 |
| unrine culture | plate colony counts CFU ul to ml number times 1000 |
| S aureus | gram+ purple cluster cocci |
| E.coli | gram- pink/red rods |
| bacillus spp. | gram- pink/red rods |
