Ha Lithibela-mafu li Khaotsa ho Sebetsa: Ho Utloisisa Kotsi ea Carbapenemase le Karolo ea ho Fumanoa ka Potlako

Ho hanyetsa likokoana-hloko (AMR) e se e le e 'ngoe ea liphephetso tse matla ka ho fetisisa tsa bophelo bo botle lefatšeng ka bophara tsa mehleng ea rona.Lethathamo la Likokoana-hloko tsa Bohlokoa tsa Baktheria la 2024 (BPPL)e lokollotsoeng ke Mokhatlo oa Lefatše oa Bophelo, libaktheria tse 'maloa tse hanyetsanang le carbapenem—ho kenyeletsoaAcinetobacter baumannii, Pseudomonas aeruginosa, le Enterobacteriaceae e hanelang carbapenem—e ntse e aroloa e leLikokoana-hloko tsa "Bohlokoa ba Bohlokoa", e emelang boemo bo phahameng ka ho fetisisa ba tšokelo bophelong ba sechaba lefatšeng ka bophara. Likokoana-hloko tsena li amahanngoa le tšoaetso e matla e amanang le tlhokomelo ea bophelo bo botle le mekhoa e fokolang ea kalafo, e leng se totobatsang tlhoko e potlakileng ea ho ntlafatsa tlhahlobo, tlhokomelo le tlhokomelo ea likokoana-hloko.

Lithibela-mafu esale e le tšireletso ea rona e matla ka ho fetisisa khahlanong le tšoaetso ea baktheria. Leha ho le joalo, kajeno, sesebelisoa sena se matla se tobane le tšokelo e ntseng e hola le e kotsi: ho hanyetsa likokoana-hloko (AMR). Empa ho thoe'ng haeba lithibela-mafu tseo u li nkang li sa sebetse? E 'ngoe ea mabaka a maholo a ho hlōleha hona ke enzyme e bitsoangcarbapenase.

Kamoo Lithibela-mafu li Sebetsang Kateng

Lithibela-mafu li sebetsa ka ho shebana le lits'ebetso tse itseng ka har'a libaktheria, li sitisa bokhoni ba tsona ba ho phela le ho ikatisa:

1. Ho Kopanya Lebota la Sele: Ka mohlala, di-penicillin di sitisa mabota a disele tsa baktheria, di etsa hore di senyehe.
2. Tlhahiso ea Protheine: Meriana e kang tetracycline le macrolides e thibela li-ribosome tsa baktheria, e emisa tlhahiso ea protheine.
3. Ho ikatisa ha DNA/RNA: Fluoroquinolones e thibela lienzyme tsa baktheria tse hlokahalang bakeng sa ho ikatisa ha DNA.
4. Botšepehi ba Membrane ea Sele: Li-polymyxin li senya lera la baktheria, e leng se lebisang lefung la sele.
5. Litsela tsa Metabolic: Li-sulfonamides li thibela lits'ebetso tsa bohlokoa tsa baktheria, joalo ka ho hlophisoa ha folic acid.
   

   Mekhoa ena e etsa hore lithibela-mafu li sebetse hantle haholo. Leha ho le joalo, keketseho ea ho hanyetsa lithibela-mafu e fokotsa matla a tsona, e leng se etsang hore ho be thata ho phekola tšoaetso e 'ngoe.

    

   Carbapenemase: Mokhoa oa Tšireletso ea Baktheria

   Carbapenemase ke enzyme e hlahisoang ke libaktheria tse itseng e sebetsang e le thebe, e etsang hore lithibela-mafu tsa carbapenem li se sebetse. Enzyme ena e senya carbapenems pele li ka kena liseleng tsa baktheria, e li thibela ho etsa mosebetsi oa tsona oa ho loantša libaktheria. Ka lebaka leo, libaktheria tse nang le carbapenemase li ka phela le ho ata esita le ha ho e-na le lithibela-mafu tse matla.
