Mycobacterium Tuberculosis Nucleic Acid ma Rifampicin Resistance

Fa'amatalaga Puupuu:

O lenei pusa e talafeagai mo le suʻesuʻeina lelei o le Mycobacterium tuberculosis DNA i faʻataʻitaʻiga sputum tagata i vitro, faʻapea foʻi ma le faʻaogaina o le homozygous i le 507-533 amino acid codon itulagi o le rpoB gene lea e mafua ai le Mycobacterium tuberculosis rifampicin resistance.

Epidemiology

Mycobacterium tuberculosis , e le'i umi ae pei o le Tubercle bacillus, TB, o le siama fa'ama'i e mafua ai le mamapala.I le taimi nei, o vailaʻau faʻamaʻi faʻamaʻi e masani ona faʻaaogaina muamua e aofia ai isoniazid, rifampicin ma hexambutol, ma isi. Ae ui i lea, ona o le le saʻo o le faʻaogaina o vailaʻau faʻamaʻi faʻamaʻi ma uiga o le fausaga puipui puipui o le mycobacterium tuberculosis, o le mycobacterium tuberculosis e atiaʻe ai le teteʻe o vailaʻau i vailaʻau faʻamaʻi, lea e aumaia ai luitau ogaoga i le puipuia ma le togafitia o le mamapala.

O le Rifampicin na fa'aaogaina lautele i togafitiga o gasegase mamapala talu mai le tuai o 1970s, ma e iai sona aafiaga taua.O le filifiliga muamua lava e fa'apu'upu'u le chemotherapy o tagata mama'i mamapala.O le tetee i le Rifampicin e mafua ona o le suiga o le kenera rpoB.E ui lava o loʻo faʻaauau pea ona faʻaalia fualaau fou e tetee atu ai i le mamapala, ma o loʻo faʻaauau pea le faʻaleleia atili o le aoga o tagata mamaʻi mamaʻi, o loʻo i ai pea le le lava o vailaʻau faʻamaʻi, ma o le tulaga o le faʻaogaina o vailaʻau le talafeagai i falemaʻi e fai si maualuga.E manino lava, o le Mycobacterium tuberculosis i tagata mamaʻi e maua i le mama mama e le mafai ona faʻaumatia atoa i se taimi talafeagai, lea e iu ai ina oʻo atu i tikeri eseese o vailaʻau faʻasaina i le tino o le tagata maʻi, faʻaumiina le ala o le faʻamaʻi, ma faʻateleina ai le lamatiaga o le oti o le tagata maʻi.
