Chikwama cha sampuli ndi thumba losindikizidwa, lomwe limagwiritsidwa ntchito pokonza zitsanzo, kupititsa patsogolo kapena kusungunula zitsanzo pozindikira mitundu yosiyanasiyana ya mabakiteriya muzakudya.
▶ Mapangidwe a Sampling Thumba
1. Thumba losindikizidwa: limafuna kusinthasintha, kukana kukhudzidwa, ndi kukana kwamphamvu kwa puncture, ndipo ndiloyenera kugwiritsidwa ntchito mu homogenizers.
2. Zosefera zosefera: Zimafunika kuti mabakiteriya azitha kudutsa pawindo la fyuluta momasuka, ndipo kukula kwa kusiyana komwe zotsalira zachitsanzo zatsekedwa ndizopambana.
3. Zamadzimadzi: zambiri 225mL, kutengera kulemerera kapena dilution chofunika ndi mitundu yosiyanasiyana.
▶ Kugwiritsa ntchito thumba lachitsanzo
Amagwiritsidwa ntchito pokonza zitsanzo, kupititsa patsogolo kapena kusungunula zitsanzo pozindikira mitundu yosiyanasiyana ya mabakiteriya muzakudya.
▶ Kugawika kwa matumba a zitsanzo
Malingana ndi zakumwa zosiyanasiyana, zimagawidwa kukhala: Buffered Peptone Water Sampling Bag, Phosphate Buffered Saline Solution Sampling Bag, Normal Saline Sampling Bag, GN Enrichment Liquid Sampling Bag, Shiga Zeng Bacterial Liquid Sampling Bag, 10% Sodium Chloride Sampling Liquid Sampling Bag , 3% Sodium Chloride Alkaline Protein Jelly Water Sampling Bag, 0.1% Peptone Water Sampling Bag, thumba lachitsanzo la Madzi Osabala Osabala, Thumba Lowonjezera la Phosphate Buffer Sampling, Nutritional Meat Soup Sampling Matumba, etc.
Malinga ndi zosefera zosiyanasiyana, zikhoza kugawidwa mu: zonse fyuluta zitsanzo thumba ndi theka fyuluta zitsanzo thumba.
▶ Chenjezo
1. Zoletsedwa kuyesa kuchipatala.
2. Ndi yoyenera kwa oyesera ophunzitsidwa.
3. Mukagwiritsidwa ntchito, chitetezo chiyenera kutengedwa ndi magolovesi ndi mask.
4. Sing'anga yotayidwa iyenera kutayidwa ndi autoclaving.
5. Ndikoletsedwa kugwiritsa ntchito mankhwalawo akatha ntchito kapena chipwirikiti ndi kuipitsidwa.
