Mycobacterium tuberculosis: Pathogenesis uye Kurongwa

Mycobacterium tuberculosis (MTB/M. tuberculosis) ndiyo hosha huru uye inonyanya kukonzera tuberculosis (TB). Inogona kupinda mumuviri wemunhu kuburikidza nenzira yekufema, nzira yekugaya, kana ganda rakakuvara uye mucous membranes, ichibata nhengo dzakasiyana-siyana uye ichikonzera mhando dzakasiyana dzeTB. TB yemapapu, inonyanya kutapuriranwa nemadonhwe, inokonzeresa vanhu vanopfuura 80% yeTB. Zviratidzo zvakajairika zvinosanganisira kukosora, kugadzirwa kwemapumu, uye hemoptysis. Mushure mehutachiona mumapapu, bhakitiriya inogona kupararira kuburikidza neropa kuenda kune dzimwe nzira, zvichikonzera TB yemaskeletal, weti, kana gastrointestinal.[2]

MTB chikamu cheMycobacterium, iyo inosanganisira:

• Mycobacterium tuberculosis complex (MTBC): Inosanganisira M. tuberculosis, M. bovis, M. africanum, M. canettii, uye M. microti, pakati pezvimwe. Kunyange zvazvo M. tuberculosis iriyo inonyanya kukonzera TB, M. bovis naM. africanum zvinogonawo kukonzera chirwere ichi.
• Mycobacteria isingapfuure TB (NTM).
• Mycobacterium leprae, chikonzero chemaperembudzi.

Nzira dzekuongorora murabhoritari

Kuongorora chirwere cheTB nemazvo uye nenguva kwakakosha kuti chirwere ichi chidzorwe zvinobudirira. Sangano reWorld Health Organization rinosimbisa kuti chirwere ichi chinopararira.Tekinoroji dzekuongorora TB nekukurumidza dzakachinja zvakanyanya kuonekwa kweTB nekugonesa kuzivikanwa kwezvirwere zvinotapukira zvine hungwaru uye zvakananga ukuwo dzichiona kusakwanisa kushandisa mishonga.[1].

- Microscopy netsikae: Kurapa chirwere cheTB kunoramba kuri chiratidzo chetsika, sezvo kuchibvumira kuzivikanwa kwezvisikwa zvipenyu uye kuchitsigira kuongororwa kwemishonga uye kuongororwa kwemajini. Zvisinei, nekuda kwekukura kunonoka kweMycobacterium tuberculosis, mhedzisiro inowanzo tora mavhiki maviri kusvika masere, zvichideredza kushanda kwayo mukurapa pakuita sarudzo nekukurumidza.

-Kuedzwa kweMadziviriro emuviri: Nzira dzekudzivirira muviri, dzinosanganisira bvunzo yeganda re tuberculin (TST) uye bvunzo dzekuburitsa interferon-gamma (IGRAs), dzinoona mhinduro dzemuviri kuhutachiona hweTB. Kunyange zvazvo dzichibatsira pakuona hutachiona hwakavanda, bvunzo idzi hadzigone kusiyanisa pakati pehutachiona hwakasimba nehwakambovapo uye nekudaro dzine hushoma hwekuongororwa munzvimbo dzine mutoro wakanyanya.

-Kuongorora Mamorekuru (NAAT): Miedzo yakavakirwa paDNA yakaita senucleic acid amplification (NAAT) inokurudzirwa nekuda kwekunzwa kwayo kwakanyanya uye kujeka kwayo.

-Kutevedzana kweChizvarwa Chinotevera kwakanangwa (tNGS): Tekinoroji dzekutsvaga dzakanangwa dzinopa ruzivo rwakanyanya rwekuchinja kunokonzerwa nekusagona kurapwa. Mitemo yeWHO inokurudzira tNGS senzira yepamusoro yekuona kusagona kurapwa mushure mekuongororwa, ichitsigira nzira dzekurapa dzakanyatsojeka [3].

-Kutevedzana kweMetagenomic Next-Generation (mNGS): Kutevedzana kwemetagenomic kunoita kuti pave neruzivo rwakakwana rwezvirwere zvakasiyana-siyana pasina kusarudza kwazvinoitwa. Nzira iyi inonyanya kukosha muzviitiko zvakaoma kana zvisina kujeka zvekiriniki, zvinosanganisira hutachiona hwakasiyana-siyana uye varwere vane dziviriro yemuviri inoderera, uko kuongororwa kwakajairika kungave kusina kukwana.

WHO inoenderera mberi ichisimbisa kuti kusimbiswa kwehutachiona hwemabhakitiriya kwakakosha pakutanga kurapwa kwakakodzera uye kuvandudza mhedzisiro yemurwere, zvichisimbisa kukosha kwekubatanidza kuongororwa kwemamorekuru muzvirongwa zvekudzora TB [1].

Mhinduro Dzakakwana Dzekuongorora Mamorekuru kubva kuMacro & Micro-Test
