Lub hnab sampling yog ib lub hnab ntim, uas yog siv rau kev ua qauv, pre-enrichment lossis qauv dilution thaum kuaj pom ntau hom kab mob hauv cov khoom noj.
▶ Muaj cov hnab ntim khoom
1. Lub hnab ntim khoom: yuav tsum tau yooj yim, cuam tshuam, thiab muaj zog puncture kuj, thiab yog haum rau siv homogenizers.
2. Cov ntxaij lim dej: Nws yuav tsum muaj cov kab mob kab mob tuaj yeem dhau los ntawm cov ntxaij lim dej dawb, thiab qhov loj ntawm qhov sib txawv qhov twg cov qauv seem raug thaiv yog qhov zoo tshaj plaws.
3. Liquid: feem ntau 225mL, nyob ntawm seb qhov enrichment los yog dilution xav tau los ntawm txawv hom.
▶ Kev siv lub hnab ntim khoom
Nws yog siv rau kev ua qauv, pre-enrichment lossis qauv dilution thaum kuaj pom ntau hom kab mob hauv cov zaub mov.
▶ Kev faib cov hnab ntim khoom
Raws li cov kua sib txawv, nws muab faib ua: Buffered Peptone Water Sampling Bag, Phosphate Buffered Saline Solution Sampling Bag, Ib txwm Saline Sampling Bag, GN Enrichment Liquid Sampling Bag, Shiga Zeng Bacterial Liquid Sampling Bag, 10% Sodium Chloride Tryptone Enrichment Liquid Sampling , 3% Sodium Chloride Alkaline Protein Jelly Water Sampling Bag, 0.1% Peptone Water Sampling Bag, Sterile Distilled Water Sampling bag, Improved Phosphate Buffer Sampling Bags, Nutritional Meat Soup Sampling Bags, thiab lwm yam.
Raws li cov ntxaij lim dej sib txawv, nws tuaj yeem muab faib ua: puv lim hnab ntim thiab ib nrab lim hnab ntim khoom.
▶ Ceeb toom
1. Txwv tsis pub kuaj mob.
2. Nws tsuas yog tsim nyog rau cov neeg xyaum ua haujlwm.
3. Thaum siv, kev tiv thaiv yuav tsum tau siv hnab looj tes thiab daim npog qhov ncauj.
4. Muab pov tseg nruab nrab yuav tsum muab pov tseg los ntawm autoclaving.
5. Nws yog txwv tsis pub siv cov khoom thaum nws tas sij hawm los yog turbid thiab polluted.
