Ngokutsho kophando olupapashwe kwi-Annals of Internal Medicine, isihluzo samanzi esithengiswayo sisenokuba sinegalelo ekosulelweni kwezigulana ezine zotyando lwentliziyo eBrigham and Women's Hospital, ezintathu kuzo eziye zafa.
Ukuqhambuka kwe-M. abscessus okunxulumene nokhathalelo lwempilo, okuchazwa njenge-"pathogen engaqhelekanga kodwa echazwe kakuhle kwi-nosocomial", ngaphambili kwakubizwa ngokuba "ziinkqubo zamanzi ezingcolisiweyo" ezifana noomatshini bomkhenkce namanzi, izinto zokufumisa, imibhobho yesibhedlele, kwizigulana ezityandwayo, izixhobo zokufudumeza nezokupholisa, amayeza kunye nezibulali-ntsholongwane.
NgoJuni ka-2018, ulawulo losulelo lwesibhedlele iBrigham and Women's Hospital lubike ukuba iMycobacterium abscesus subsp.abscessus ihlasele izigulana ezininzi ezityandwa intliziyo. Usulelo lwesisu, olunokubangela usulelo lwegazi, imiphunga, ulusu, kunye nezicubu ezithambileyo, ingakumbi kubantu abaneenkqubo zomzimba ezibuthathaka.
Abaphandi benze uphando oluchazayo ukuze baqonde ngcono amaqela osulelo. Bakhangele izinto ezifanayo phakathi kwamatyala, njengezixhobo zokufudumeza nezokupholisa ezisetyenzisiweyo, okanye amagumbi otyando, umgangatho wesibhedlele kunye namagumbi, kunye nokufikelela kwizixhobo ezithile. Abaphandi bakwathathe iisampulu zamanzi kuwo onke amagumbi abaguli ababehlala kuwo, kunye nakumaqula amabini okusela kunye nabenzi bomkhenkce kumgangatho wotyando lwentliziyo.
Zonke izigulana ezine “zanyangwa nge-multidrug antimycobacterial therapy,” kodwa ezintathu kuzo zafa, ubhale watsho uKlompas kunye noogxa bakhe.
Abaphandi bafumanise ukuba zonke izigulana zikwinqanaba elifanayo lesibhedlele kodwa azinazo ezinye izinto ezifanayo. Xa behlola abenzi bomkhenkce kunye nabasasazi bamanzi, baqaphele ukukhula okukhulu kwe-mycobacteria kwiibhloko zeqela, kodwa kungekhona kwenye indawo.
Emva koko, besebenzisa ulandelelwano lwe-genome epheleleyo, bafumene izinto ezifanayo ngokwemfuza kwimithombo yokusela kunye noomatshini bomkhenkce kumgangatho wesibhedlele apho kwakukho khona izigulane ezinesi sifo. Amanzi akhokelela kwiimoto adlula kwisixhobo sokucoca amanzi esihluziweyo ngekhabhoni esinokukhanya kwe-ultraviolet, nto leyo abaphandi abayifumeneyo inciphisa amanqanaba e-chlorine emanzini, nto leyo enokukhuthaza iintsholongwane ze-mycobacteria ukuba zihlale kwiimoto.
Emva kokuba izigulane ezisengozini enkulu zitshintshele kumanzi acocekileyo acocekileyo, zandisa ukugcinwa kwezixhobo zokuhambisa amanzi, zacima inkqubo yokucoca, akwabakho matyala angakumbi.
“Ukufaka izixhobo zombhobho zorhwebo ukuphucula incasa nokunciphisa ivumba lamanzi okusela ezigulana kunokuba nemiphumo ebeyingalindelekanga yokukhuthaza ukuhlanganiswa kweentsholongwane kunye nokuzala,” babhala abaphandi. Imithombo yamanzi (umz. ukwandisa ukusetyenziswa kwamanzi ukuze kuncitshiswe ukusetyenziswa kobushushu) inokunyusa ingozi yokosuleleka kwesigulana ngokunciphisa ukuhanjiswa kwekhlorine nokukhuthaza ukukhula kweentsholongwane.”
UKlompas kunye noogxa bakhe bagqibe kwelokuba uphando lwabo “lubonisa umngcipheko wemiphumo engalindelekanga enxulumene neenkqubo ezenzelwe ukuphucula ukusetyenziswa kwamanzi ezibhedlele, ukuthambekela kokungcoliswa kweentsholongwane zomkhenkce kunye nemithombo yokusela, kunye nomngcipheko oku okuwubangelayo kwizigulane.” inkxaso yeenkqubo zolawulo lwamanzi zokujonga nokuthintela usulelo lwe-nosocomial mycobacterial.
“Ngokubanzi, amava ethu aqinisekisa iingozi ezinokubakho zokusebenzisa amanzi empompini kunye nomkhenkce ekunyamekeleni izigulane ezisengozini, kunye nexabiso elinokubakho leenkqubo ezintsha zokunciphisa ukuvezwa kwezigulane ezisengozini kumanzi empompini kunye nomkhenkce ngexesha lonyango oluqhelekileyo,” babhala.
