Kiti yekuona Streptococcus nucleic acid yeBoka B (Enzymatic Probe Isothermal Amplification)
1. Kukosha kwekuona
Boka reB streptococcus (GBS) rinowanzo wanikwa munhengo yemukadzi nemudumbu, izvo zvinogona kukonzera hutachiona hwekutanga (GBS-EOS) muvana vacheche kuburikidza nekutapurirana kubva kuna amai kuenda kumwana, uye ndicho chikonzero chikuru chepneumonia yevana vacheche, meningitis, septicemia uye kunyange rufu. Muna 2021, Nyanzvi yeKubvumirana paKutarisira Kliniki kweVana Vachangoberekwa Vane Njodzi Yakanyanya Kutapukirwa neKutapukirwa Kwevana Vacheche muChikamu Chimwe Chemadzimai neVacheche veChina Maternal and Child Health Association yakaratidza kuti kuongororwa kweGBS mavhiki 35-37 vasati vasununguka uye kudzivirira antibiotic mukati mekusununguka (IAP) inzira dzinoshanda dzekudzivirira GBS-EOS muvana vacheche.
2. Matambudziko anosangana nenzira dziripo dzekuongorora
Kuputika kwema membranes nguva isati yakwana (PROM) zvinoreva kuputika kwema membranes nguva isati yakwana, inova dambudziko rinowanzoitika munguva yekusununguka. Kuputika kwema membranes nguva isati yakwana. Nekuda kwekuputika kwema membranes, GBS munhengo yemukadzi yevakadzi vari kusununguka inogona kupararira ichienda kumusoro, zvichikonzera hutachiona mukati mechibereko. Njodzi yehutachiona inoenderana nekukura panguva yekuputika kwema membranes (> 50% yevakadzi vane pamuviri vanosununguka mukati memaawa 1-2 mushure mekuputika kwema membranes, kana kunyange maawa 1-2).
Nzira dziripo dzekuongorora hadzigone kuzadzisa zvizere zvinodiwa panguva yakakodzera (< 1h), kunyatsojeka uye kuonekwa kweGBS panguva yekutumira.
| Zvishandiso zvekuongorora | Tsika yebhakitiriya | Nguva yetsika: 18-24hKana bvunzo yekunzwa kwemushonga: wedzera maawa 8-16 | 60% chiyero chekuonekwa kwechirwere ichi; panguva yekutorwa kwesampuli, chinogona kubatwa nemabhakitiriya akadai seEnterococcus faecalis akakomberedza chibereko nepahuro, zvichikonzera mhedzisiro yenhema / yenhema. |
| Immunochromatography | Nguva yekuona: 15min. | Kunzwa kwacho kwakaderera, uye zviri nyore kupotsa kuonekwa, kunyanya kana huwandu hwebhakitiriya huri hudiki, zvakaoma kuona, uye nhungamiro hadzikurudzirwi zvakanyanya. | |
| PCR | Nguva yekuona: 2-3h | Nguva yekuona inopfuura maawa maviri, uye mudziyo wePCR unofanirwa kuyedzwa mumapoka, uye hazvigoneke kutevera bvunzo. |
3. Zvinhu zvakakosha pakugadzirwa kweMacro & Micro-Test
Kukurumidza kuona: Uchishandisa nzira yekuwedzera tembiricha inogadziriswa neenzyme ine patent, varwere vane hutachiona vanogona kuziva mhedzisiro nekukurumidza mushure memaminitsi mashanu.
Kuonekwa chero nguva, hapana chikonzero chekumirira: ine analyzer ye nucleic acid amplification inodziya nguva dzose Easy Amp, uye ma module mana anomhanya ega, uye ma samples anoongororwa paanosvika, saka hapana chikonzero chekumirira ma samples.
Mhando dzakasiyana-siyana dzesamples: swab yekubereka, rectal swab kana mixed vaginal swab inogona kuonekwa, iyo inoenderana nezvinodiwa neGBS, inovandudza mwero wekuona positive uye inoderedza mwero wekusaziva chirwere.
Kushanda kwakanaka kwazvo: kuongororwa kwekiriniki kwemuenzaniso mukuru wepakati penzvimbo dzakawanda (> nyaya 1000), kunzwa kwemuviri 100%, kujeka kwemuviri 100%.
Reagent yakavhurika: inoenderana nechishandiso chePCR chinoshandiswa pakugadzira fluorescence.
