Shigella Antigen Rapid Test

Npaj siv

Shigella Antigen Rapid Test (Feces) yog ib qho hauv vitro immunoassay rau qhov ncaj thiab zoo nrhiav tau ntawm Shigella antigens los ntawm tib neeg quav. Nws yog npaj los pab txhawm rau txhawm rau kuaj qhov sib txawv sai ntawm shigellosis. Cov txiaj ntsig tsis zoo tsis txwv tus kab mob Shigella thiab yuav tsum tau lees paub los ntawm kab lis kev cai kab lis kev cai lossis kev tshuaj ntsuam molecular.

Taw qhia

Shigella yog ib tug genus ntawm Gram-negative, facultative anaerobic, non-spore-forming, non-motile bacilli thiab yog tus ua tus neeg sawv cev ntawm tib neeg shigellosis. Shigella yog ib qho ntawm cov kab mob ua rau mob raws plab thoob ntiaj teb. Shigella hom yog cais los ntawm plaub serogroups (Pab A, B, C thiab D) nrog ntau yam serotypes raws li serological thiab biochemical tsom xam1. Feem ntau cov tsos mob ntawm shigellosis yog raws plab, ua npaws, xeev siab, ntuav, mob plab, thiab flatulence1, 2. Nws kuj tseem paub tias ua rau lub plab loj thiab mob plab. Muaj tsawg zaus, cov menyuam yaus yuav qaug dab peg. Cov tsos mob feem ntau pib ob mus rau plaub hnub tom qab noj tshuaj thiab kav ntev li ob peb hnub lossis ntau lub lis piam. Raws li kev tiv thaiv kab mob ntawm cov tib neeg, cov tsos mob ntawm tus kab mob asymptomatic mus rau mob bacillary dysentery. Hemolytic uremic syndrome tuaj yeem tshwm sim tom qab S. dysenteriae hom 1 lossis S. flexneri kab mob 3. Shigella tseem cuam tshuam raws li ib qho ntawm cov kab mob ua rau mob caj dab reactive thoob ntiaj teb4.

Shigellosis yog ib qho kab mob nyob rau hauv cov teb chaws uas muaj kev huv huv tsis zoo. Feem ntau 10 ~ 20 feem pua ​​​​ntawm cov kab mob enteric, thiab 50 feem pua ​​​​ntawm cov ntshav raws plab lossis kab mob plab ntawm cov menyuam yaus, tuaj yeem ua tus yam ntxwv xws li shigellosis1. Kev kis kab mob yog pib los ntawm kev noj cov shigellae thiab kis los ntawm fecal-qhov ncauj txoj kev feem ntau los ntawm cov tes tsis huv, tsawg zaus los ntawm cov zaub mov tsis huv lossis dej. Shigella hom kab mob kis tau yooj yim heev nrog cov kab mob tsawg (102 ~ 104 CFU), thiab lub sij hawm incubation yog 1 ~ 3 hnub 5. Carriage ntawm kab mob persistence li ntawm ib lub hlis tom qab convalescence. Yog li ntawd, kev kuaj mob sai sai yog lub luag haujlwm tseem ceeb hauv kev soj ntsuam kab mob thiab kev tswj xyuas.

Kev kuaj mob ntawm tus mob shigellosis tuaj yeem tsim los ntawm kev cais cov kab mob los ntawm cov kab mob raws plab fecal kab lis kev cai thiab tom qab morphological thiab biochemical tsom xam. Nrog rau cov cuab yeej tshwj xeeb thiab cov txheej txheem kev tshaj lij, PCR amplification ntawm plasmid noob ntawm Shigella hom thiab DNA hybridization tuaj yeem muab kev txheeb xyuas ceev thiab ceev ntawm Shigella1. Enzyme-linked immuosorbent assay (ELISA) thiab immunochromatography assay (ICA) siv cov tshuaj tiv thaiv kab mob los yog tshuaj tiv thaiv kab mob pom cov tshuaj tiv thaiv tshwj xeeb ntawm Shigella kuj tuaj yeem siv los tshuaj xyuas cov quav rau cov kab mob.

Shigella Antigen Rapid Test siv sijhawm li 10 ~ 20 feeb xwb thiab tsuas yog xav tau ib qho me me ntawm tib neeg cov quav los ua. Nws yog ib qho yooj yim thiab ceev kev kuaj mob rau tus kab mob Shigella.
