Igoa o oloa
HWTS-OT045 Carbapenem Resistance Gene (KPC/NDM/OXA 48/OXA 23/VIM/IMP) Pusa Su'esu'ega (Fluorescence PCR)
Epidemiology
O vailaʻau faʻamaʻi Carbapenem o vailaʻau faʻamaʻi β-lactam faʻatasi ma le lautele o alaleo faʻamaʻi faʻamaʻi ma sili ona malosi gaioiga faʻamaʻi.Ona o lona mautu i le β-lactamase ma le maualalo o le oona, ua avea ma se tasi o vailaʻau antibacterial sili ona taua mo le togafitia o faʻamaʻi pipisi ogaoga.Carbapenems e matua mautu i plasmid-mediated extended-spectrum β-lactamases (ESBLs), chromosomes, ma plasmid-mediated cephalosporinases (AmpC enzymes).

Galulue Galuega
Filifiliga 1.
Fa'atonuga ole su'ega: Macro & Micro-Test General DNA/RNA Kit (HWTS-3019-50, HWTS-3019-32, HWTS-3019-48, HWTS-3019-96) (lea e mafai ona faʻaaogaina i le Macro & Micro-Test Automatic Nucleic Acid Extractor (HWTS-3006C, HWTS-3006B)) e Jiangsu Macro & Micro-Test Med-Tech Co., Ltd.. Faʻaopoopo le 200μL o le saline masani ile o le thallus precipitate.O laasaga mulimuli ane e tatau ona mulimulita'i i fa'atonuga mo le su'eina, ma o le voluma elution fautuaina e100μL.
Filifiliga 2.
Fautuaina le fa'aaogaina o le fa'aputuina: Nucleic Acid Extraction po'o le Purification Reagent (YDP302) e Tiangen Biotech (Beijing) Co., Ltd. E tatau ona amata le fa'aputuga e tusa ma le la'asaga 2 o le fa'atonuga mo le fa'aoga (fa'aopoopo le 200μL o le pa puipui GA i le thallus precipitate. , ma lulu seʻia oʻo ina taofi atoa le thallus).Fa'aaoga le RNase/DNase vai e leai se totogi mo le fa'amama, ma le fa'atonuga o le voluma e 100μL.
Filifiliga 3.
Fautuaina le fa'asusuina o mea fa'apipi'i: Macro & Micro-Su'ega Fa'ata'ita'i Fa'ata'ita'iga Reagent.E mana'omia ona fufulu le fa'ata'ita'iga o le sputum e ala i le fa'aopoopoina o le 1mL o le masima masani i le fa'afefeteina o lo'o ta'ua i luga, fa'amama i le 13000r/min mo le 5 minute, ma lafoa'i le supernatant (tausia le 10-20μL o le supernatant).Mo colony mama ma rectal swab, faaopoopo 50μL o faataitaiga faamatuu atu reagent tuusao i le ua taua i luga togafitia thallus precipitate, ma le laasaga mulimuli e tatau ona aveesea e tusa ai ma faatonuga mo le faaaogaina.
