Le teknoloji ibalulekile ekulweni nokumelana ne-antibiotic kunye nokuthintela ukusasazeka kwezifo ezinobungozi zebhaktheriya.

I-Insulated Isothermal PCR: Ukwenza lula uvavanyo lwe-PCR ngeTekhnoloji yoBuchule

Insulated isothermal PCR imele uguqulo lotshintsho kubuchwepheshe be-PCR, ivumela ukwandiswa kwe-DNA kwiqondo lobushushu elingaguqukiyo ngaphandle kwesidingo sokuhamba ngebhayisekile eshushu. Ngokungafaniyo ne-PCR yemveli, efuna umatshini we-PCR ukuba afudumale kunye neesampulu ezipholileyo, I-PCR ye-isothermal egqunyiweyo isebenzisa ubushushu obuzinzileyo, obunye ukuphumeza i-DNA amplification. Olu tshintsho lwenza lula uvavanyo lwe-PCR ngokususa imfuno yezixhobo ezintsonkothileyo kunye nokunciphisa ixesha kunye namandla afunekayo ukukhulisa. Insulated isothermal PCR ibonakalise ukuxabiseka ngokukodwa kwi-point-of-care diagnostics, apho ukuphatheka kunye nesantya kubalulekile. Ukukwazi ukuvelisa iziphumo ezithembekileyo ngokukhawuleza kwenza ukuba kube yinto efanelekileyo yokukhetha iindawo apho ukufikelela kwiziseko zebhubhoratri kunqunyelwe, njengemimandla ekude okanye ngexesha lomsebenzi. Ukulula kunye nokusebenza kakuhle kwe I-PCR ye-isothermal egqunyiweyo balungisa ngokutsha ubume boxilongo lwemolekyuli.

Ukufunyanwa kweeMveliso ze-PCR: Ukuqinisekisa ukuchaneka kunye nokuthembeka

I ukufunyanwa kweemveliso zePCR linyathelo elibalulekileyo ekuqinisekiseni impumelelo yenkqubo yePCR kunye nokuchonga ubukho beDNA ekujoliswe kuyo. Ukulandela ukukhulisa, iimveliso ze-PCR kufuneka zichongwe ukuze kuqinisekiswe ukuba i-DNA echanekileyo iye yandiswa. Kukho iindlela ezininzi zokulungisa ukufunyanwa kweemveliso zePCR, kubandakanywa i-gel electrophoresis, i-fluorescence-based assays, kunye ne-PCR yexesha langempela, nganye inikezela ngeenzuzo ezahlukeneyo ngokuxhomekeke kwisicelo. I ukufunyanwa kweemveliso zePCR ayibalulekanga kuphela ekuqinisekiseni ubukho bentsholongwane ethile kodwa kunye nokulinganisa inani le-DNA ekujoliswe kuyo kwisampulu. Oku kubaluleke ngakumbi ekujongweni komthamo wentsholongwane egazini, ekuxilongeni umhlaza, kunye nokubeka iliso kokusingqongileyo. Ikhono lokubona ngokuthembekileyo iimveliso ze-PCR ziqinisekisa ukuba iziphumo zokuxilonga zichanekile, ziyakwazi ukuveliswa kwakhona, kwaye ziluncedo ekukhokeleni izigqibo zonyango.

I-PCR yokuchongwa kweBhaktheriya: Umgangatho weGolide kwi-Microbial Diagnostics

I-PCR yokuchongwa kwebhaktheriya ibe ngumgangatho wegolide ekuchongeni iintsholongwane ze-bacterial pathogens, inika inqanaba lokuchaneka kunye nesantya esingenakulinganiswa neendlela zokuxilonga eziqhelekileyo. Nokuba kukwimeko yeklinikhi okanye yendalo esingqongileyo, I-PCR yokuchongwa kwebhaktheriya isetyenziselwa ukubona uluhlu olubanzi losulelo lwebhaktiriya, ukusuka kwiintsholongwane eziqhelekileyo ezifana ne-Staphylococcus aureus kunye ne-Escherichia coli ukuya kwiibhaktiriya ezinqabileyo okanye ezinzima-kwinkcubeko. Ngokujolisa kwiziphawuli ezithile zemfuza ezizodwa kwiintlobo zebhaktiriya, I-PCR yokuchongwa kwebhaktheriya yenza ubhaqo olukhawulezayo, oluchanekileyo kunye nokwahlula phakathi kweebhaktheriya ezisondeleleneyo. Oku kubaluleke ngakumbi ekufumaneni iibhaktheriya ezixhathisa amayeza okubulala iintsholongwane, apho ukuchongwa kwangethuba kunokuba nefuthe elibonakalayo kukhetho lonyango kunye namanyathelo olawulo losulelo. Uphuhliso oluqhubekayo lwee-assays ezisekelwe kwi-PCR zokuchongwa kwebhaktheriya luyaqhubeka nokwandisa isicelo salo kwi-diagnostics, ukuqinisekisa ukuba ababoneleli bezempilo banokuhlala phambi kweengozi zebhaktheriya ezivelayo.
