Ngokocwaningo olwanyatheliswa kuyi-Annals of Internal Medicine, isisefo samanzi esidayiswayo singase sibe nomthelela ekuthelelekeni kweziguli ezine ezihlinzwa inhliziyo eBrigham naseSibhedlela Sabesifazane, ezintathu zazo sezishonile.
Ukuqubuka kwe-M. abscessus okuhlotshaniswa nokunakekelwa kwezempilo, okuchazwa ngokuthi “i-nosocomial pathogen engavamile kodwa echazwe kahle, ngaphambili eyayibizwa ngokuthi “izinhlelo zamanzi angcolile” njengemishini yeqhwa namanzi, ama-humidifiers, amapayipi asesibhedlela, ezigulini ezihlinzwa nge-bypass, ukushisa. kanye nezinto zokupholisa, imithi kanye nezibulala-magciwane.
NgoJuni 2018, ukulawulwa kokutheleleka kweBrigham kanye Nesibhedlela Sabesifazane kwabika ukuthi i-Mycobacterium abscessus subsp.abscessus ihlasela ezigulini ezimbalwa ezihlinzwa inhliziyo. Ukutheleleka ngethumba, okungadala izifo zegazi, amaphaphu, isikhumba, nezicubu ezithambile, ikakhulukazi kubantu abanamasosha omzimba abuthakathaka.
Abacwaningi benze ucwaningo oluchazayo ukuze baqonde kangcono amaqoqo okutheleleka. Babebheka izinto ezifanayo phakathi kwamakesi, njengemishini yokushisisa neyokupholisa esetshenziswa, noma amagumbi okuhlinza, iphansi lesibhedlela namakamelo, kanye nokutholakala kwemishini ethile. Abacwaningi baphinde bathatha amasampula amanzi kuwo wonke amagumbi iziguli ezazihlala kuwo, kanye nasemithonjeni yokuphuza emibili kanye nabenzi beqhwa endaweni yokuhlinzwa yenhliziyo.
Zonke iziguli ezine "zelashwa ngenkuthalo nge-multidrug antimycobacterial therapy," kodwa ezintathu zazo zashona, uKlompas nozakwabo babhala.
Abacwaningi bathole ukuthi zonke iziguli zisezingeni elifanayo esibhedlela kodwa azikho ezinye izinto ezifanayo. Lapho behlola abenzi beqhwa nabahlinzeki bamanzi, babona ukukhula okuphawulekayo kwe-mycobacteria emabhuloki eqoqo, kodwa hhayi kwenye indawo.
Khona-ke, besebenzisa ukulandelana kofuzo lonke, bathola izakhi ezifanayo zofuzo emithonjeni yokuphuza nemishini yeqhwa phansi esibhedlela lapho iziguli ezinegciwane zazikhona. Amanzi aholela ezimotweni adlula kwisihlanzi samanzi esicwengiwe nge-carbon esichayeka ekukhanyeni kwe-ultraviolet, okutholwe abacwaningi behlisa amazinga e-chlorine emanzini, okungase kukhuthaze i-mycobacteria ukuthi iqoqe izimoto.
Ngemuva kokuthi iziguli ezisengozini enkulu zishintshele emanzini acwengekile oyinyumba, zandisa ukugcinwa kwemishini yamanzi, zacisha uhlelo lokuhlanza, azibange zisababikho amacala.
"Ukufaka amapayipi okudayisa ukuze kuthuthukiswe ukunambitheka kanye nokunciphisa iphunga lamanzi okuphuza eziguli kungase kube nemiphumela engahlosiwe yokugqugquzela ukuzalanisa kwama-microbial colonization kanye nokuzalana," kubhala abacwaningi. imithombo yamanzi (isib. ukugaywa kabusha kwamanzi okwenyuka ukuze kuncishiswe ukusetshenziswa kokushisa) kungase kwandise ingozi yokutheleleka kwesiguli ngokuphambana ne-chlorine futhi kukhuthaze ukukhula kwamagciwane.”
UKlompas nozakwabo baphetha ngokuthi ukuhlola kwabo “kubonisa ingozi yemiphumela ebingahlosiwe ehlobene nezinhlelo eziklanyelwe ukuthuthukisa ukusetshenziswa kwamanzi ezibhedlela, ukuthambekela kokungcoliswa amagciwane eqhwa nemithombo yokuphuza, kanye nobungozi lokhu okububeka ezigulini.” ukwesekwa kwezinhlelo zokulawulwa kwamanzi ukuze kuqashwe futhi kuvinjwe izifo ze-nosocomial mycobacterial.
"Ngokubanzi, ulwazi lwethu luqinisekisa izingozi ezingaba khona zokusebenzisa amanzi kampompi kanye neqhwa ekunakekeleni iziguli ezisengozini, kanye nenani elingaba khona lezinhlelo ezintsha zokunciphisa ukuchayeka kweziguli ezisengozini emanzini kampompi neqhwa ngesikhathi sokunakekelwa okujwayelekile," babhala. .
