Ngokophononongo olupapashwe kwi-Annals of Internal Medicine, isihluzo samanzi sorhwebo sinokuba negalelo kusulelo lwezigulane ezine zotyando lwentliziyo eBrigham nakwiSibhedlele sabaseTyhini, abathathu kubo bafa.
Ukuqhambuka kwe-abscessus yezempilo enxulumene nokhathalelo lwempilo, echazwa njenge "pathogen enqabileyo kodwa echazwe kakuhle ye-nosocomial", eyayibizwa ngokuba "kwiinkqubo zamanzi ezingcolileyo" ezifana nomkhenkce kunye noomatshini bamanzi, i-humidifiers, i-plumbing yesibhedlele, kwizigulane ezenza utyando lwe-bypass, ukufudumeza. kunye nezixhobo zokupholisa, amayeza kunye nezibulali ntsholongwane.
NgoJuni ka-2018, iBrigham kunye nolawulo losulelo lweSibhedlele sabaseTyhini babika i-Mycobacterium abscessus subsp.abscessus kwizigulana ezininzi ezenza utyando lwentliziyo. Usulelo lwamathumba, olunokubangela usulelo lwegazi, lwemiphunga, ulusu, kunye nezihlunu ezithambileyo, ngakumbi kubantu ababuthathaka amajoni omzimba.
Abaphandi baqhube uphononongo oluchazayo ukuqonda ngcono amaqela osulelo. Bakhangela izinto ezifanayo phakathi kweemeko, ezifana nezixhobo zokufudumeza nezokupholisa ezisetyenziswayo, okanye amagumbi otyando, imigangatho namagumbi esibhedlele, nokufikelela kwizixhobo ezithile. Abaphandi baphinde bathatha iisampulu zamanzi kwigumbi ngalinye izigulana ezihlala kulo, kunye nakwimithombo emibini yokusela kunye nabenzi bomkhenkce kumgangatho wotyando lwentliziyo.
Bonke abaguli abane "banyangwa ngokusebenzayo ngonyango lwe-antimycobacterial," kodwa abathathu kubo basweleka, uKlompas kunye noogxa babhala.
Abaphandi bafumanise ukuba zonke izigulana zazikwinqanaba elinye esibhedlele kodwa zazingenazo ezinye izinto ezifanayo. Xa behlola abenzi be-ice kunye nabahambisa amanzi, baqaphela ukukhula okuphawulekayo kwe-mycobacteria kwiibhloko ze-cluster, kodwa kungekhona kwenye indawo.
Emva koko, besebenzisa ulandelelwano lwe-genome epheleleyo, bafumana izinto ezifanayo ngokwemfuza kwimithombo yokusela kunye noomatshini bomkhenkce kumgangatho wesibhedlele apho kwakukho abaguli abosulelekileyo. Amanzi akhokelela kwiimoto adlula kwi-carbon-filtered water purifier kunye nokuvezwa kokukhanya kwe-ultraviolet, apho abaphandi bafumene ukunciphisa amanqanaba e-chlorine emanzini, okunokukhuthaza i-mycobacteria ukuba ibe koloni kwiimoto.
Emva kokuba izigulane ezinobungozi obuphezulu zitshintshele kumanzi ahlambulukileyo ahlambulukileyo, zandisa ukugcinwa kwezixhobo zamanzi, zacima inkqubo yokucoca, akuzange kubekho iimeko.
"Ukufaka izixhobo zemibhobho yokuthengisa ukuphucula incasa kunye nokunciphisa ivumba lamanzi okusela izigulana kunokuba neziphumo ebezingalindelekanga zokukhuthaza i-microbial colonization kunye nokuzala," abaphandi babhala. ubutyebi bamanzi (umzekelo, ukugaywa kwakhona kwamanzi ukucutha ukusetyenziswa kobushushu) kunokonyusa ngempazamo ingozi yokosuleleka kwesigulana ngokuphelisa izibonelelo zeklorine nokukhuthaza ukukhula kweentsholongwane.”
UKlompas noogxa bakhe baqukumbela ngelithi uhlolisiso lwabo “lubonisa umngcipheko wemiphumo ebingalindelekanga enxulumene nenkqubo eyilelwe ukuphucula ukusetyenziswa kwamanzi ezibhedlele, utyekelo lokungcoliswa ziintsholongwane zomkhenkce nemithombo yokusela, nobungozi boku kubaguli.” inkxaso yeenkqubo zolawulo lwamanzi ukujonga nokuthintela usulelo lwe-nosocomial mycobacterial.
"Ngokubanzi, amava ethu aqinisekisa ubungozi obunokubakho bokusebenzisa amanzi ompompo kunye nomkhenkce ekunyamekeleni abaguli abasengozini, kunye nexabiso elinokubakho lamanyathelo amatsha okunciphisa ukuvezwa kwezigulana ezisesichengeni kumanzi ompompo kunye nomkhenkce ngexesha lokhathalelo lwesiqhelo," babhala. .
