Basic steps of the sugar centrifugation technique |
1. Weigh out 2 grams of feces and add to 98 ml of water - refrigerate for a few+ hours 2. Mix and then decant 10ml into centrifuge tube 3. Centrifuge for 5 minutes 4. Decant, add sugar solution, centrifuge for 5 minutes 5. Fill with sugar solution until meniscus forms add coverslip, wait for 1 hour 6. Place coverslip on slide and examine |
|
How to quantify sugar centrifugation fecal technique results |
Count the oocysts at 10x objective. Multiply the number of each type of ova/oocysts by 5 to determine EPG. Multiply by a factor of 10 if only 1 gram of feces was used. |
|
In what instance is the McMasters procedure superior to sugar centrifugation? |
For detection of nematode strongyle eggs
Also detects roundworm eggs, tapeworm eggs, and coccidian oocysts |
|
Basic steps of McMasters procedure |
1. Get 4 grams of feces and mix with 26ml of NaCl 2. Pour suspension through gauze to remove large particles 3. Use pipette to fill both chambers of the counting slide 4. Examine under low power (10x) |
|
How to quantify McMasters procedure results |
Count both grids on the 2 chamber slide, multiply the number of eggs of each type by 25 to get EPG. |
