Iqhaza Eliyinhloko Lobuchwepheshe Be-ELISA Enyaweni-kanye-Nokutholwa Kwegciwane Lesifo Somlomo kanye Nokuguqulwa Kwemboni

Enqubweni yokuthuthukiswa kwemboni yemfuyo emhlabeni wonke,-kanye{1}} nesifo somlomo, njengesifo esiyingozi kakhulu esiwubhubhane lwezilwane, bekulokhu kuyizinto ezibalulekile zokuvikela nokulawula embonini. I-Foot-kanye-i-Mouth Disease Virus (FMDV) ingathelela izilwane ezihlukahlukene ezinenselo-ezinamanqina njengezingulube, izinkomo, nezimvu, zibangele izifo ezithathelwanayo eziyingozi kakhulu, ezinomkhuhlane, kanye nezifo ezithathelwanayo kakhulu. Akulethi nje kuphela ukulahlekelwa okukhulu kwezomnotho embonini yemfuyo kodwa futhi kungase kube nomthelela omubi kakhulu ekuhwebeni kwamazwe ngamazwe. Eminyakeni yakamuva, ngenqubekelaphambili eqhubekayo yesayensi nobuchwepheshe, ubuchwepheshe be-Enzyme-I-Linked Immunosorbent Assay (ELISA) yenze inqubekelaphambili emangalisayo emkhakheni wezinyawo{9}}kanye{10}}nokutholwa kwegciwane lesifo somlomo futhi sekuyizindlela ezibalulekile zokuqinisekisa ukuthuthuka kwemboni yemfuyo.

I-ELISA Technology: Ithuluzi Elinamandla Lezinyawo-kanye-Nokutholwa Kwezifo Zomlomo

Ubuchwepheshe be-ELISA busekelwe kumgomo wokubopha okuthile phakathi kwama-antigen nama-antibodies. Ngokusabela kwe-enzyme-yezinto ezilebuli, isignali yokuthola iyakhuliswa, ngaleyo ndlela kutholakale ukutholakala okunembile kwezinyawo-kanye{3}}namasosha omzimba egciwane lesifo somlomo noma ama-antigen. Uma kuqhathaniswa nezindlela ezijwayelekile zokuhlonza, ezifana ne-Virus Neutralization Test (VNT), i-ELISA inezinzuzo eziningi. Okokuqala, i-ELISA inesivinini sokuthola ngokushesha nokusebenza okulula. Ingakwazi ukucubungula inani elikhulu lamasampuli ngesikhathi esifushane ukuze ihlangabezane nezidingo{7}}zokuqapha ubhubhane olukhulu. Okwesibili, lobu buchwepheshe bunezidingo eziphansi uma kuqhathaniswa zemishini yokuhlola kanye nama-opharetha futhi akudingekile ukuncika kubuchwepheshe obuyinkimbinkimbi bosikompilo lwamangqamuzana, okwenza kube lula ukuthi kudume futhi kusetshenziswe eziteshini zezilwane nasemapulazini aphansi. Ukwengeza, ukunemba nokuphindaphinda kwemiphumela yokutholwa kwe-ELISA kuphezulu uma kuqhathaniswa, kunciphisa amaphutha abangelwa izici zabantu futhi kunikeze ukwesekwa kwedatha okuthembekile ekuvimbeleni nasekulawuleni ubhubhane.

Ukuthuthukiswa Okusha Kwezindlela Zokutholwa ze-ELISA

Abacwaningi bahlola futhi benza izinto ezintsha njalo, bazibophezele ekuthuthukiseni izindlela zokuthola i-ELISA ezisebenza kahle nezibucayi. Isibonelo, ithimba labacwaningi baseNyuvesi yaseNyakatho-ntshonalanga ye-A&F yakhe inkundla ye-ELISA ye-multiplex immunochromatographic emakwe nge-crystal violet. Le ELISA plateform ayikwazi nje ukubona izinsalela ze-streptomycin ne-chloramphenicol ezinyaweni-kanye{3}kanye{3}negciwane lesifo somlomo ngesikhathi esisodwa kodwa futhi ikwazi ukuthola ukubonwa kwekhwalithi kanye{4}}nomthamo omncane. Ekusetshenzisweni okungokoqobo, le nkundla ibonisa ukuzinza okuhle ekutholeni amasampula okudla afana nobisi noju. Izinga lokutakula elinyukile liphakathi kuka-83.82% no-113.38%, futhi ukuchezuka okujwayelekile okuhlobene (RSD) kusebangeni elingu-0.4% - 4.18%. Le ndlela emisha yehlisa ukusetshenziswa kwezinyibilikisi eziphilayo, ifinyeze isikhathi sokulungiselela, futhi igwema ukuhlangana okuphindaphindiwe{12}} kokuxhumanisa ama-molecule ezinto eziphilayo, ivule indlela entsha{13}}yesayithi kanye{14}}nokutholwa komphumela ophezulu.

I-ELISA Technology Iqhuba Uguquko Lwemboni

1. Ukugqugquzela Ukuvimbela kanye Nokulawula Okunembayo Emapulazini

Emapulazini, kubalulekile ukuthi ngesikhathi esifanele futhi ubambe ngokunembile isimo sokuzivikela komzimba kanye nesimo esiwumqedazwe sezilwane. Ukusetshenziswa okusabalele kobuchwepheshe be-ELISA kwenza amapulazi akwazi ukubona i-sera yezilwane njalo, ahlole umphumela wokuzivikela komzimba wemithi yokugoma, futhi alungise uhlelo lokugoma ngesikhathi esifanele. Ngokuqapha izinga lamasosha omzimba komama ezilwaneni ezisencane, isikhathi esifanele sokugoma kokuqala singanqunywa ukwenza ngcono umphumela wokugoma. Ngesikhathi esifanayo, qaphela njalo izinga lamasosha omzimba ezilwane ngemva kokugonywa ukuze uqinisekise ukuthi izinga elifanelekile lokugonywa komhlambi lifinyelela izinga futhi livimbele ngempumelelo ukwenzeka nokusabalala kwesifo sonyawo-kanye{4}}nomlomo. Isibonelo, uma izinga elifanelekile lamasosha omzimba komama emhlambini libalelwa ku-50%, ukugonywa kokuqala kuyenziwa. Inyanga eyodwa ngemva kokugoma kokuqala, kunikezwa ukugonywa kwe-booster, bese kunikezwa ukugonywa kwe-booster njalo ezinyangeni ezi-4 kuya kweziyisi-6. Izinga le-antibody litholwa yi-ELISA ukuze kuqinisekiswe umphumela wokugoma, futhi abantu abahlulekayo ukugoma bahlonzwa ngokushesha futhi{11}}bagonywe kabusha.

2. Ukuqinisa Ukuqapha Ubhubhane Ngeziphathimandla Ezilawulayo

Iziphathimandla ezilawulayo zingasebenzisa ubuchwepheshe be-ELISA ukuze zenze-ukuhlola okungahleliwe okungahleliwe kwemikhiqizo yezilwane emakethe, zithole ngokushesha izifo zezinyawo{{-kanye{2}}nezifo zomlomo, futhi zinqande ukusabalala kwalolu bhubhane. Ezindaweni zokuhlaba nokucubungula, uhlelo lokuhlolwa nokubhaliswa kwemfuyo engena endaweni isetshenziswa ngokuqinile. Ngenkathi kuhlolwa izitifiketi zokuhlukaniswa zemvelaphi kanye nemfuyo kanye nezinkukhu ezihlonza imfuyo ezohlatshwa ingena endaweni, indlela ye-ELISA isetshenziswa ukuze kutholwe amasosha omzimba-kanye{6}}negciwane lesifo somlomo ku-sera yezilwane. Uma isilwane okusolakala ukuthi sinegciwane, kuthathwa izinyathelo ezihambisanayo ngokushesha, njengokubika kuziphathimandla zezolimo nezasemaphandleni nokuthumela amasampula amahle ku-National Foot-kanye-ne-Mouth Disease Reference Laboratory ukuze kuhlaziywe i-pathogen, njll., ukulawula ngempumelelo ingozi yokusabalala kobhubhane. Ngaphezu kwalokho, ubuchwepheshe be-ELISA buphinde bunikeze isisekelo sedatha yeziphathimandla ezilawulayo ukuze zenze izinqubomgomo zokuvimbela nokulawula izifo eziwumshayabhuqe zesayensi nezinengqondo, ukukhuthaza ukuphathwa okujwayelekile kwayo yonke imboni yemfuyo.

3. Ukuthuthukisa Ukuthuthukiswa Kwezimboni Ezihlobene

Inqubekelaphambili yobuchwepheshe bokutholwa kwe-ELISA iqhubekisele phambili ukuthuthukiswa okunamandla kwezimboni ezihlobene. Abakhiqizi bekhithi yokutholwa bayaqhubeka nokwenyusa utshalomali lwabo lwe-R&D, bathuthukisa ikhwalithi yomkhiqizo nokusebenza, futhi bahlangabezane nesidingo semakethe sama-reagents okutholwa asebenza kahle nanembile. Ngaso leso sikhathi, amabhizinisi akhiqiza izinsimbi nezinto zokusebenza nawo athuthukisa ngokuqhubekayo asekela okokusebenza okutholwayo okuzenzakalelayo ukuthuthukisa ukusebenza kahle nokunemba. Isibonelo, ezinye izihlaziyi ze-chemiluminescence immunoassay ezizenzakalelayo ngokugcwele ezihlanganiswe nezindlela ezintsha zokuthola i-ELISA zingafinyelela ukutholwa okuzenzakalelayo nokuphezulu-kwenani elikhulu lamasampuli ngesikhathi esifushane, kunikeze isixazululo sokuthola esilula nesisebenza kahle somkhakha. Ngaphezu kwalokho, izimboni zezinsizakalo ezifana nokuqeqeshwa kanye nokubonisana mayelana nobuchwepheshe be-ELISA nazo sezivele, zinikeza ukwesekwa okuqinile kokuthandwa nokusetshenziswa kobuchwepheshe.

Amathembawe ELISA

Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, ubuchwepheshe be-ELISA buzoqhubeka nokusungula futhi buthuthuke emkhakheni wezinyawo-kanye{1}}nokutholwa kwegciwane lomlomo. Ngokuzayo, silindeleke ukuthi sibone ukuvela kwezindlela zokuhlonza ezibucayi kakhulu, eziqondile, nezisheshayo ze-ELISA, okuthuthuke kakhudlwana ukunemba nokusebenza kahle kokutholwa kwezinyawo{3}kanye{4}}nezifo zomlomo. Ngesikhathi esifanayo, ngokuhlanganiswa okujulile kobuchwepheshe obusafufusa njengobuhlakani bokwenziwa kanye nedatha enkulu enobuchwepheshe be-ELISA, ukuhlaziya{6}}kwangempela kwesikhathi kanye nokubikezelwa kwedatha yesifo esiwumqedazwe kuzofezeka, kuhlinzekwe izinqumo zesayensi nezinembile{7}}zokwenza ukwesekwa kokuvimbela nokulawula ubhubhane. Esimweni sokuthuthukiswa okudidiyelwe kwemboni yemfuyo yomhlaba wonke, ubuchwepheshe be-ELISA buzodlala indima ebaluleke kakhulu ekuqinisekiseni impilo yezilwane kanye nokugqugquzela ukuthuthukiswa okusimeme kwemboni yemfuyo, futhi buzokwenza umnikelo omkhulu ekuphepheni kokudla emhlabeni wonke kanye nokuzinza komnotho.
