Fa'aoga Fa'amoemoe
Escherichia coli O157:H7 (E.coli O157:H7) o se siama kalama-negative o le ituaiga Enterobacteriaceae, lea e maua mai ai le tele o Vero toxin.I le falema'i, e masani lava ona tupu fa'afuase'i i le tiga ogaoga o le manava ma le manava manava, soso'o ai ma le manava manava i ni nai aso mulimuli ane, e mafai ona i'u ai i le fiva pe leai fo'i se fiva, ma le oti i tulaga ogaoga.O lenei pusa e fetaui lelei mo le suʻesuʻeina o le Escherichia coli O157: H7 i meaʻai, vai faʻataʻitaʻiga, feces, vomit, siama faʻaleleia vai ma isi faʻataʻitaʻiga e faʻaaoga ai le mataupu faavae o le PCR taimi moni.O le pusa o se PCR SYSTEM ALL-READY ( Lyophilized), o loʻo i ai le DNA amplification enzyme, faʻamalo tali, faʻamatalaga faʻapitoa ma suʻega e manaʻomia mo le suʻeina o le PCR fluorescent.

Teuina & Ola Fa'asa
(1) E mafai ona feaveaʻi le pusa ile vevela potu.
(2) O le fata ola e 18 masina ile -20℃ ma le 12 masina ile 2℃~30℃.
(3) Va'ai le igoa i luga o le pusa mo le aso gaosiga ma le aso e muta ai.
(4) E tatau ona teuina le lyophilized powder version reagent i le -20 ℃ pe a maeʻa le faʻamavae ma le toe faʻamaisaina - e tatau ona itiiti ifo i le 4 taimi.
