I-Mycobacterium Tuberculosis Nucleic Acid kanye ne-Rifampicin Resistance

I-Mycobacterium tuberculosis , ngokushesha nje njenge-Tubercle bacillus, i-TB, igciwane le-pathogenic elidala isifo sofuba.Njengamanje, imithi elwa nesifo sofuba yomugqa wokuqala esetshenziswa kakhulu ihlanganisa i-isoniazid, i-rifampicin ne-hexambutol, njll. Imithi yomugqa wesibili yokulwa nesifo sofuba ihlanganisa i-fluoroquinolones, i-amikacin ne-kanamycin, njll. Imithi emisha ethuthukisiwe i-linezolid, i-bedaquiline ne-delamani, njll. Nokho, ngenxa yokusetshenziswa okungalungile kwemithi elwa nesifo sofuba kanye nezici zesakhiwo sodonga lwamangqamuzana e-mycobacterium tuberculosis, isifo sofuba se-mycobacterium siqala ukumelana nemithi elwa nesifo sofuba, okuletha izinselele ezinkulu ekuvimbeleni nasekwelapheni isifo sofuba.

I-Rifampicin ibisetshenziswa kabanzi ekwelapheni iziguli ezinesifo sofuba samaphaphu kusukela ngasekupheleni kwawo-1970, futhi inomphumela obalulekile.Kube yisinqumo sokuqala ukufushanisa ukwelashwa ngamakhemikhali ezigulini ze-pulmonary tuberculosis.Ukumelana ne-rifampicin kubangelwa ikakhulukazi ukuguqulwa kofuzo lwe-rpoB.Nakuba imishanguzo emisha yokulwa nesifo sofuba ihlale iphuma, kanye nokusebenza emtholampilo kweziguli ezinesifo sofuba samaphaphu nakho kuqhubekile nokuba ngcono, kusenokuntuleka kwezidakamizwa ezilwa nesifo sofuba, futhi ukwenzeka kokusetshenziswa kwezidakamizwa okungenangqondo emtholampilo kuphezulu uma kuqhathaniswa.Ngokusobala, isifo sofuba iMycobacterium ezigulini ezinesifo sofuba samaphaphu asikwazi ukubulawa ngokuphelele ngesikhathi esifanele, okuholela emazingeni ahlukene okumelana nemithi emzimbeni wesiguli, sandise isikhathi sokugula, futhi kwandisa ingozi yokufa kwesiguli.
