Gulu B Streptococcus nucleic acid detection kit (Enzymatic Probe Isothermal Amplification)
1. Kufunika kwa kuzindikira
Gulu B streptococcus (GBS) nthawi zambiri limapezeka m'mimba mwa akazi ndi m'matumbo, zomwe zingayambitse matenda oyamba (GBS-EOS) mwa makanda kudzera mu kufalikira kuchokera kwa mayi kupita kwa mwana, ndipo ndiye chifukwa chachikulu cha chibayo cha makanda, meningitis, septicemia komanso imfa. Mu 2021, Expert Consensus on Clinical Management of High-Risk Newborns with Early-onset Infection in One-Room of Mothers and Manners of China Moternal and Child Health Association inanena kuti kuyezetsa GBS milungu 35-37 asanabadwe komanso kupewa maantibayotiki m'mimba mwa mayi (IAP) kunali njira zothandiza zopewera GBS-EOS mwa makanda obadwa kumene.
2. Mavuto omwe akukumana nawo pogwiritsa ntchito njira zamakono zopezera
Kuphulika kwa nembanemba msanga (PROM) kumatanthauza kuphulika kwa nembanemba musanabadwe, zomwe ndi vuto lofala nthawi yobereka. Kuphulika kwa nembanemba msanga Chifukwa cha kuphulika kwa nembanemba, GBS m'chikazi cha amayi oyembekezera imatha kufalikira mmwamba, zomwe zimapangitsa kuti matenda a m'mimba ayambe. Chiwopsezo cha matenda chimakhala chofanana ndi kukula kwa nembanemba panthawi yophulika (> 50% ya amayi apakati amabereka mkati mwa maola 1-2 kuchokera pamene nembanemba zaphulika, kapena ngakhale maola 1-2).
Njira zodziwira matenda zomwe zilipo sizingakwaniritse mokwanira zofunikira pa nthawi yake (< 1h), kulondola komanso kuzindikira GBS pa nthawi yobereka.
| Zida zodziwira | Chikhalidwe cha mabakiteriya | Nthawi ya chikhalidwe: 18-24hNgati mayeso a kukhudzidwa ndi mankhwala: onjezerani maola 8-16 | Chiŵerengero cha 60% cha kupezeka kwa kachilomboka; panthawi yopereka zitsanzo, kachilomboka kamakhudzidwa ndi mabakiteriya monga Enterococcus faecalis kuzungulira nyini ndi thako, zomwe zimapangitsa kuti pakhale zotsatira zabodza/zabodza. |
| Kujambula kwa Immunochromatography | Nthawi yodziwira: 15min. | Kuzindikira matendawa n'kochepa, ndipo n'kosavuta kuphonya kuzindikira, makamaka ngati kuchuluka kwa mabakiteriya kuli kochepa, n'kovuta kuzindikira, ndipo malangizo sakulimbikitsidwa kwambiri. | |
| PCR | Nthawi yodziwika: maola 2-3 | Nthawi yodziwira matendawa ndi yoposa maola awiri, ndipo chipangizo cha PCR chiyenera kuyesedwa m'magulu, ndipo sizingatheke kutsatira mayesowo. |
3. Zofunika kwambiri pa zinthu za Macro & Micro-Test
Kuzindikira mwachangu: Pogwiritsa ntchito njira yodziwira kutentha kokhazikika ya enzyme digestion probe, odwala omwe ali ndi kachilomboka amatha kudziwa zotsatira zake pakangopita mphindi 5.
Kuzindikira nthawi iliyonse, palibe chifukwa chodikira: ili ndi chowunikira kutentha kosalekeza cha nucleic acid amplification Easy Amp, ndipo ma module anayiwo amayenda pawokha, ndipo zitsanzo zimawunikidwa zikafika, kotero palibe chifukwa chodikira zitsanzo.
Mitundu yambiri ya zitsanzo: swab ya m'mimba, swab ya m'matumbo kapena swab yosakanikirana ya m'mimba imatha kupezeka, zomwe zimakwaniritsa malangizo a GBS, zimathandizira kuzindikira bwino komanso zimachepetsa kuchuluka kwa matenda olakwika.
Kuchita bwino kwambiri: kutsimikizira kwachipatala kwa zitsanzo zazikulu m'malo ambiri (> milandu 1000), kuzindikira 100%, kutsimikizika 100%.
Chotsegula chothandizira: chimagwirizana ndi chida cha PCR cha fluorescence chomwe chimagwiritsidwa ntchito masiku ano.
