Anaerobes
| Question | Answer |
|---|---|
| MO that will not grow in oxygen | obligate of strict anaerobe |
| anaerobes are killed in a few minutes when exposed to | oxygen |
| proper collection is important with anaerobes because they are present in large number in | normal flora |
| collection techniques must avoid the contamination of the specimen by | normal anerobic flora |
| anaerobes are found | deep in the body (so no O2) |
| how many types of anaerobic transport systems are there? | 3 |
| rubber stoppered collection vials are used for | liquid specimens |
| oxygen free collections tubs for | swab specimens |
| self contained anaerobic bag for | tissue specimens |
| some gram positive anaerobes will stain | pink |
| gram staining will improve in an | anaerobic chamber |
| cannot be used when processing anaerobes | candle jars |
| specimens may be processed in a | biological safety cabinet after incubation |
| anaerobes are incubated in | anaerobic jars or pouches |
| anaeobic conditions are maintained by a flow of | N2 gas |
| Anaerobic media should be pre reduced by | being stored under anaerobic conditions |
| cycloserine cefoxitin fructose agar or egg yolk agar is used for | Clostridium difficile |
| purchased pre reduced media | pras |
| pras stands for | prereduced, anaerobically sterilized media |
| name for gram neg, anaerobic rods | bacteroide |
| what grows on Laked kanamycin-vancomycin blood agar? | bacteroides and Prevotella |
| anaerobes grow | slowly |
| they only generate | 2 atp |
| controls for anerobic condtions | Clostridium, colorless in the absence of oxygen |
| plates that show no growth are incubated for | 5 additional days |
| Anaerobes give off identifying | gases |
| gases can be analyzed for identification by | Gas liquid chromatography and High resolution gas chromatography |
