Igama lemveliso
I-HWTS-OT090-Vancomycin-resistant Enterococcus kunye ne-Gene Restant-resistant Kit (i-PCR ye-Fluorescence)
I-Epidemiology
Ukumelana neChiza kukwabizwa ngokuba kukunganyangeki kwechiza, kubhekiselele kuxhathiso lwebhaktheriya kwisenzo samachiza okulwa neentsholongwane.Nje ukuba uxhathiso lwamachiza lwenzekile, umphumo wechemotherapy wamachiza uya kuncitshiswa kakhulu.Ukumelana neChiza kwahlulwe kuxhathiso lwangaphakathi kunye noxhathiso olufunyenweyo.Ukuchasana kwangaphakathi kuchongwa yi-bacterial chromosomal genes, edluliselwe kwisizukulwana ukuya kwisizukulwana, kwaye ayiyi kutshintsha.Ukuxhathisa okufunyenweyo kungenxa yokuba emva kokunxibelelana namayeza okubulala iintsholongwane, iintsholongwane zitshintsha iindlela zazo zemetabolism ukuze zingabulawa ngamayeza okubulala iintsholongwane.
Iijini zokuxhathisa ivancomycin iVanA kunye neVanB zifunyenwe ukunganyangeki ngamachiza, apho iVanA ibonisa amanqanaba aphezulu okuxhathisa ivancomycin kunye neteicoplanin, iVanB ibonisa amanqanaba ahlukeneyo okuxhathisa kwivancomycin, kwaye inovelwano kwiteicoplanin.IVancomycin isoloko isetyenziswa ezonyango ukunyanga usulelo lwentsholongwane yeGram-positive, kodwa ngenxa yokuvela kwe vancomycin-resistant enterococci (VRE), ngakumbi i-enterococcus faecalis kunye ne-enterococcus faecium, ebalelwa ngaphezulu kwe-90%, izise imingeni emikhulu kunyango lwezonyango. .Okwangoku, akukho ichiza elithile le-antibacterial kunyango lwe-VRE.Ngaphezu koko, i-VRE inokudlulisela imizila yokumelana neziyobisi kwezinye ii-enterococci okanye ezinye iibhaktheriya ezi-Gram-positive.
