Enterococcus e tetee i Vancomycin ma Gene e tetee i Vailaau
Igoa o oloa
HWTS-OT090-Vancomycin-tetetete Enterococcus ma Fualaau Fa'asaina Gene Su'esu'ega Pusa (Fluorescence PCR)
Epidemiology
Tete'e i Fualaau Fa'asaina ua ta'ua fo'i o le tete'e o vaila'au, e fa'atatau i le tete'e atu o siama i le gaioiga o vaila'au fa'ama'i.O le taimi lava e tula'i mai ai le tete'e atu i vaila'au, o le a matua fa'aitiitia le aafiaga o le chemotherapy o vaila'au.Tete'e i Fualaau fa'asaina ua vaevaeina i totonu o le tete'e ma maua tete'e.O le tete'e i totonu e fuafua e kenera chromosomal siama, pasi mai lea tupulaga i lea tupulaga, ma o le a le suia.O le tete'e maua e mafua ona o le mea moni pe a uma ona fa'afeso'ota'i ma vaila'au fa'ama'i, e suia e siama a latou lava ala fa'atosina ina ia aua ne'i fasiotia i latou e vaila'au.
Ole vancomycin resistance genes VanA ma VanB e maua mai fualaau faasaina, e aofia ai le VanA o loʻo faʻaalia le maualuga o le tetee i le vancomycin ma le teicoplanin, VanB o loʻo faʻaalia tulaga eseese o le tetee i le vancomycin, ma e maaleale ile teicoplanin.Vancomycin e masani ona faʻaaogaina ile falemaʻi e togafitia ai faʻamaʻi pipisi o le Gram-positive, ae ona o le tulaʻi mai o le vancomycin-resistant enterococci (VRE), aemaise lava enterococcus faecalis ma enterococcus faecium, e sili atu nai lo le 90%, ua aumaia ai ni luʻitau fou fou i togafitiga falemaʻi. .I le taimi nei, e leai se vailaʻau faʻamaʻi faʻamaʻi faʻapitoa mo togafitiga o le VRE.E le gata i lea, e mafai fo'i e le VRE ona tu'uina atu kenera e tete'e atu i vaila'au i isi enterococci po'o isi siama Gram-positive.
