Ngokusho kocwaningo olwanyatheliswa kuyi-Annals of Internal Medicine, isihlungi samanzi esithengiswayo kungenzeka ukuthi sibe nomthelela ekuthelelekeni kweziguli ezine ezihlinzwa inhliziyo eBrigham and Women's Hospital, ezintathu zazo esezishonile.
Ukuqubuka kwe-M. abscessus okuhlobene nokunakekelwa kwempilo, okuchazwe “njengegciwane elingavamile kodwa elichazwe kahle le-nosocomial”, ngaphambili okwakubizwa ngokuthi “izinhlelo zamanzi ezingcolile” njengemishini yeqhwa namanzi, izinto zokuhlanza umoya, amapayipi ezibhedlela, iziguli ezihlinzwa ngokuhlinzwa, imishini yokushisa nokupholisa, imithi kanye nezibulala-magciwane.
NgoJuni 2018, ukulawulwa kokutheleleka kweBrigham and Women's Hospital kwabika ukuthi i-Mycobacterium abscesus subsp.abscessus ihlasela iziguli eziningana ezihlinzwa inhliziyo. Ukutheleleka kwe-tumor, okungabangela ukutheleleka kwegazi, amaphaphu, isikhumba, kanye nezicubu ezithambile, ikakhulukazi kubantu abanezivikeli mzimba ezibuthakathaka.
Abacwaningi benze ucwaningo oluchazayo ukuze baqonde kangcono amaqoqo okutheleleka. Babheke izinto ezifanayo phakathi kwamacala, njengemishini yokushisa nokupholisa esetshenziswayo, noma amakamelo okuhlinzwa, phansi nasezindlini zesibhedlela, kanye nokufinyelela imishini ethile. Abacwaningi baphinde bathatha amasampula amanzi kuwo wonke amagumbi iziguli ezazihlala kuwo, kanye nasemithombo emibili yokuphuza kanye nemishini yeqhwa phansi kokuhlinzwa kwenhliziyo.
Zonke iziguli ezine “zelashwa ngenkuthalo ngokwelashwa ngemithi eminingi yokulwa namagciwane,” kodwa ezintathu zazo zashona, kusho uKlompas nozakwabo.
Abacwaningi bathole ukuthi zonke iziguli zazisezingeni elifanayo lesibhedlela kodwa zazingenazo ezinye izici ezifanayo. Lapho behlola abenzi beqhwa kanye nabasabalalisi bamanzi, baqaphele ukukhula okukhulu kwama-mycobacteria kuma-cluster blocks, kodwa hhayi kwenye indawo.
Ngemuva kwalokho, besebenzisa ukulandelelana kwe-genome ephelele, bathola izakhi ezifanayo zofuzo emithonjeni yokuphuza kanye nemishini yeqhwa phansi esibhedlela lapho iziguli ezinegciwane zazikhona. Amanzi aholela ezimotweni adlula ngomshini wokuhlanza amanzi ohlungiwe ngekhabhoni ochayeka ekukhanyeni kwe-ultraviolet, abacwaningi abakutholile kunciphisa amazinga e-chlorine emanzini, okungenzeka kukhuthaze ama-mycobacteria ukuthi ahlale ezimotweni.
Ngemva kokuba iziguli ezisengozini enkulu zishintshele emanzini acwengekile angenamagciwane, zandisa ukugcinwa kwemishini yokusabalalisa amanzi, zavala uhlelo lokuhlanza, akubange kusabakho macala.
“Ukufaka izinto zokufaka amapayipi ezentengiselwano ukuze kuthuthukiswe ukunambitheka nokunciphisa iphunga lamanzi okuphuza ezigulini kungaba nemiphumela engahlosiwe yokukhuthaza ukuqongelela kwamagciwane kanye nokuzala,” kubhala abacwaningi. Imithombo yamanzi (isib. ukwanda kokusetshenziswa kabusha kwamanzi ukuze kuncishiswe ukusetshenziswa kokushisa) ingandisa ingozi yokutheleleka kwesiguli ngokunciphisa ukuphakelwa kwe-chlorine nokukhuthaza ukukhula kwamagciwane.”
UKlompas kanye nozakwabo baphetha ngokuthi ucwaningo lwabo “lubonisa ingozi yemiphumela engahlosiwe ehlotshaniswa nezinhlelo ezenzelwe ukuthuthukisa ukusetshenziswa kwamanzi ezibhedlela, ukuthambekela kokungcoliswa kwamagciwane eqhwa kanye nemithombo yokuphuza, kanye nengozi lokhu okubangela iziguli.” ukwesekwa kwezinhlelo zokuphathwa kwamanzi zokuqapha nokuvimbela ukutheleleka kwe-nosocomial mycobacterial.
“Ngokubanzi, okuhlangenwe nakho kwethu kuqinisekisa izingozi ezingaba khona zokusebenzisa amanzi ompompi kanye neqhwa ekunakekelweni kweziguli ezisengozini, kanye nokubaluleka okungenzeka kwezinhlelo ezintsha zokunciphisa ukuchayeka kweziguli ezisengozini emanzini ompompi kanye neqhwa ngesikhathi sokunakekelwa okuvamile,” babhala.
