Maitiro Ekuramba Mishonga Inorwisa Mabhakitiriya Mumabhakitiriya Anokonzera Zvirwere
Mishonga inorwisa mabhakitiriya yagara ichinzi mishonga inoshamisa, inoshandura mishonga yemazuva ano uye inoponesa hupenyu husingaverengeki. Zvisinei, kushanda kwemishonga iyi kuri kuramba kuchiderera nekuda kwekuwedzera kwekusagona kurwisa mishonga inorwisa mabhakitiriya mumabhakitiriya anokonzera zvirwere. Nzira dzinoshandiswa nemabhakitiriya kuwana kusagona kurwisa uku dzakasiyana-siyana uye dzinopa dambudziko guru kuhutano hweveruzhinji pasi rose. Chinyorwa chino chinotarisa nzira huru dzekusagona kurwisa mishonga inorwisa mabhakitiriya mumabhakitiriya anokonzera zvirwere, zvichipa ruzivo pamusoro pedambudziko iri riri kuwedzera.
Nhanganyaya yeKuramba Kurwisa Mabhakitiriya
Kusagona kurwisa mabhakitiriya (AR) kunoitika kana mabhakitiriya achichinja nzira dzekudzivirira migumisiro yemishonga yaimboaparadza. Nzira idzi dzekudzivirira mabhakitiriya dzinobvumira mabhakitiriya kurarama, kuwanda, uye kutotamisa hunhu hwekudzivirira kune mamwe mabhakitiriya. Kukura nekupararira kweAR kunokonzerwa nezvinhu zvakati wandei, kusanganisira kushandiswa zvakanyanya uye kushandiswa zvisina kunaka kwemishonga inorwisa mabhakitiriya, kusakwana kwemaitiro ekudzivirira hutachiona, uye kushaikwa kwemishonga mitsva inorwisa mabhakitiriya iri kugadzirwa.
Nzira dzeKuramba Mishonga Inorwisa Mabhakitiriya
1. Kuora kana Kugadziriswa kweMishonga Inorwisa Mabhakitiriya muEnzymatic
Imwe yenzira dzinonyanya kushandiswa pakurwisa mabhakitiriya kugadzira ma enzymes anoderedza kana kugadzirisa ma antibiotics, zvichiita kuti asashande. Mabhakitiriya anogadzira ma enzymes akasiyana-siyana akadai:
– Beta-lactamases: Ma enzyme aya anonyanya kurwisa ma antibiotic e beta-lactam, anosanganisira penicillins ne cephalosporins, nekutyora mhete ye beta-lactam inokosha pabasa rayo rekuuraya mabhakitiriya.
– Maenzyme anochinja Aminoglycoside: Maenzyme aya anobatanidza mapoka ephosphate, acetyl, kana adenyl kumaaminoglycosides, zvichichinja chimiro chawo uye zvichikanganisa kugona kwawo kubatana nema bacterial ribosomes.
2. Kuchinja kweNzvimbo Dzakatarirwa
Mishonga inorwisa mabhakitiriya inoshanda nekusunga kune zvimwe zvinhu mukati memasero ebhakitiriya. Mabhakitiriya anogona kukura asingagoni kurwisa zvirwere izvi nekuchinja masero aya, zvichiita kuti zviomere kana kuti zvisakwanisike kuti mishonga inorwisa mabhakitiriya isunge. Mienzaniso yakajairika inosanganisira:
– Staphylococcus aureus inodzivirira Methicillin (MRSA): MRSA inowana puroteni inosunga penicillin (PBP2a) yakachinja ine simba shoma re beta-lactams.
– Mabhakitiriya asingapindi Rifampin: Kuchinja kwejini re rpoB kunochinja beta-subunit yeRNA polymerase, zvichideredza kubatana kwe rifampin.
3. Mapombi eEfflux
Mapombi eEfflux mapuroteni ekutakura ari mumembrane yemasero ebhakitiriya. Anoburitsa mishonga inorwisa mabhakitiriya kubva musero, zvichideredza huwandu hwemushonga mumasero kusvika padanho rekuuraya. Mapombi eEfflux anogona kunge akagadzirirwa mhando imwe chete yemishonga inorwisa mabhakitiriya kana kuti anogona kuburitsa mishonga yakasiyana-siyana inorwisa mabhakitiriya. Mienzaniso yakakurumbira inosanganisira:
– Tet transporters: Mapuroteni aya anoburitsa tetracycline, zvichiita kuti tetracycline isarambe.
– AcrAB-TolC: Pombi iyi yemvura inobuda muEscherichia coli inopa simba rekudzivirira mabhakitiriya akasiyana-siyana, anosanganisira fluoroquinolones uye beta-lactams.
4. Kuderedzwa kweKubvumidzwa kweKupinda
Kuchinja kwemaumbirwo nemashandiro emadziro kana mamembrane emasero ebhakitiriya kunogona kuderedza kutorwa kwemishonga inorwisa mabhakitiriya. Semuenzaniso, mabhakitiriya ane gram-negative ane membrane yekunze inoshanda seimwe chipingamupinyi. Kuchinja kwemapuroteni eporin, ayo anoshanda senzira yekupinda kwemishonga inorwisa mabhakitiriya, kunogona kuderedza kupinda kwemvura mumuviri:
– Kusagona kurwisa Beta-lactam muPseudomonas aeruginosa: Kuchinja kwemasero muOprD porin gene kunoderedza kupinda kwemasero mucarbapenems, akadai seimipenem.
5. Kuumbwa kweBiofilm
Mabhayofimu inzanga dzakaoma dzemabhakitiriya anobatanidzwa pamusoro uye anoiswa muchinhu chinobva kunze kwemuviri chinonzi extracellular polymeric substance (EPS). Mabhakitiriya ane chekuita nebhayofimu anoratidza kuramba kwakanyanya kumishonga inorwisa mabhakitiriya nekuda kwezvikonzero zvakawanda:
– Kusapinda kwemishonga inorwisa mabhakitiriya mumuviri: EPS matrix inogona kudzivirira kupararira kwemishonga inorwisa mabhakitiriya.
– Kuchinja kwemamiriro emuviri: Mabhakitiriya ari mu biofilms anowanzoita kuti masero emuviri asanyanya kubatwa nemishonga inorwisa mabhakitiriya inorwisa masero ari kukura.
6. Kudzivirirwa kweChinangwa
Mamwe mabhakitiriya anogadzira mapuroteni anodzivirira zvakananga mabhakitiriya asingaachinje. Mapuroteni aya anodzivirira anodzivisa mushonga uyu kusvika panzvimbo yawo yekusunga:
– Mapuroteni eQnr: Mapuroteni aya anodzivirira DNA gyrase netopoisomerase IV kubva kumaquinolones muQuinolone-resistant Enterobacteriaceae.
– Tet(M) naTet(O): Mapuroteni aya ekudzivirira ribosomal anodzivirira kubva ku tetracycline nekuburitsa mushonga unorwisa mabhakitiriya kubva panzvimbo yawo yekusunga pa ribosome.
Hwaro hweMajini uye Kutamisirwa kweMajini Akatsetseka
Majini ekudzivirira mabhakitiriya (ARGs) anogona kuwanikwa pa chromosome yebhakitiriya kana pazvinhu zvemajini zvinofamba, zvakaita seplasmids, transposons, uye integrons. Izvi zvinoita kuti majini ekudzivirira mabhakitiriya afambiswe zvakanaka (horizontal gene transfer) pakati pemabhakitiriya, zvichiita kuti kupararira kwekudzivirira mabhakitiriya kukurumidze. Nzira huru dzeHGT dzinosanganisira:
– Kubatana: Kutamiswa kwemaplasmid anotakura maARG kuburikidza nekubatana zvakananga kubva kumasero kuenda kumasero.
– Kuchinja: Kutorwa kwezvidimbu zveDNA zvakasununguka kubva munzvimbo ine majini anodzivirira.
– Kutapurirana: Kutapurirana kwemaARG kuburikidza nemabhakitiriya, ayo ari mavhairasi anokonzera mabhakitiriya.
Zvinoreva uye Remangwana Nhungamiro
Kupararira kwekusakwanisa kushandisa mishonga inorwisa mabhakitiriya kunokanganisa hutano hwepasi rose, zvichiita kuti kurapwa kwezvirwere zvinokonzerwa nemabhakitiriya kuome uye zvichikonzera kurwara kwakanyanya, kufa, uye mari yehutano. Kugadzirisa dambudziko iri kunoda nzira dzakasiyana-siyana:
– Kushandisa mishonga inorwisa mabhakitiriya zvine musoro: Kuisa mitemo yakaoma yekuderedza kushandiswa zvakanyanya uye kushandiswa zvisina kunaka kwemishonga inorwisa mabhakitiriya mumishonga yevanhu, mabasa emhuka, uye kurima.
– Kudzora hutachiona: Kuvandudza hutsanana, hutsanana, uye matanho ekudzivirira hutachiona munzvimbo dzehutano.
– Kutarisa: Kusimbisa masisitimu epasi rose ekutarisa kubuda nekupararira kwekusadzivirira.
– Tsvagiridzo nekuvandudzwa: Kuisa mari mukugadzirwa kwemishonga mitsva inorwisa mabhakitiriya uye dzimwe nzira dzekurapa, dzakadai semabhakitiriya, mapeptide anorwisa mabhakitiriya, uye immunotherapy.
mhedziso
Kusakwanisa kushandisa mishonga inorwisa mabhakitiriya mumabhakitiriya anokonzera zvirwere chinhu chakaoma uye chinokonzerwa nemaitiro akasiyana-siyana emamorekuru. Kunzwisisa mashandiro aya kwakakosha pakugadzira nzira dzinoshanda dzekurwisa kusakwanisa kushandisa mishonga inorwisa mabhakitiriya uye kuchengetedza kushanda kwemishonga inorwisa mabhakitiriya kuzvizvarwa zvinotevera. Kushanda pamwe chete kubva kumasayendisiti, nyanzvi dzezvehutano, vagadziri vemitemo, uye veruzhinji kwakakosha kugadzirisa dambudziko iri guru rehutano pasi rose.
