Phakathi nalolu bhubhane, ukuze kugwenywe ukusabalala kwaleli gciwane, wonke umuntu usejwayele ukugqoka imaski engalukiwe. Nakuba ukugqoka imaskhi kungavimbela ngempumelelo ukusakazeka kwaleli gciwane, ingabe ucabanga ukuthi ukugqoka imaskhi kungakunikeza ukuthula kwengqondo?
Umphumela wokuhlolwa
I-Straits Times isanda kuhlanganyela nelabhorethri yasendaweni ye-Eurofins ukutadisha ukuthi mangaki ama-microorganisms anamathiselwe kumaski angalukiwe uma egqokwe isikhathi eside, futhi imiphumela ayixazululi futhi iyaluma.
Ucwaningo oluvela elabhorethri ye-Eurofins lubonisa ukuthi uma imaskhi engalukiwe igqokwa isikhathi eside, inani lamagciwane, isikhunta, nemvubelo ngaphakathi kwemaski lizokhula.
Irekhodi lokuhlola
Ukuhlolwa kwenziwa kumamaski alahlwayo nasebenziseka kabusha amahora ayisithupha nayishumi nambili ngokulandelana, kuqoshwa ukwenzeka kwamagciwane, imvubelo, isikhunta, i-Staphylococcus aureus (ukhunta oluvamile olungadala izifo zesikhumba), kanye ne-Agrobacterium tumefaciens (ukhunta olubangela ukuqubuka kwesikhumba) phakathi nalesi sikhathi, bese uziqhathanisa.
Ukuhlolwa kuqophe amagciwane, imvubelo nesikhunta, i-Staphylococcus aureus, ne-Agrobacterium tumefaciens ngokuhlukana.
UDkt. John Common, udokotela wesikhumba eSingapore Institute of Science and Technology, engxoxweni uthe iStaphylococcus aureus ingase ikhiqize ubuthi obuyingozi kubantu.
Lawa magciwane angasakazwa ngokuthintana ngokuqondile nabantu abanaleli gciwane noma ngokusebenzisa izinto ezingcolile.
Ngakho-ke, lesi sikhunta sihlukaniswa njengento ephilayo ye-pathogenic, okusho ukuthi lesi sikhunta, esivame ukuvela kubantu abanempilo, singabangela ukulimala emzimbeni womuntu ngezinga elithile.
I-Agrobacterium ingolunye uhlobo lwamabhaktheriya angafaka i-parasitize esikhumbeni futhi abangele ukulimala emzimbeni womuntu.
Ngenhlanhla, awekho amaseli e-Staphylococcus aureus noma e-Pseudomonas aeruginosa atholakele kunoma imaphi amasampula imaski ahloliwe.
Isivivinyo samahora ayishumi nambili
Akumangalisi ukuthi abacwaningi bathola ukuthi isamba senani lemvubelo, isikhunta, namanye amagciwane kumaski agqokwa amahora ayishumi nambili laliphezulu kunekumaski eligqokwa amahora ayisithupha kuphela.
Ukugqoka imaski engalukiwe amahora ayishumi nambili kubangele amazinga ebhaktheriya aphezulu kakhulu uma kuqhathaniswa namahora ayisithupha.
Kuyaphawuleka ukuthi ucwaningo luthole ukuthi imaski esetshenziswa kabusha ngokuvamile iqukethe ama-microorganisms amaningi kunamaski angalukiwe alahlwayo.
Ukuhlola okwengeziwe okwamanje kuyadingeka ukuze kutholwe ukuthi ingabe amanye ama-microorganisms kanye namagciwane anamathele kumaski angabangela izifo noma izimo zesikhumba.
Izazi ze-microbiology zendawo zitshele i-Straits Times engxoxweni ukuthi indawo efudumele nenomswakama ngaphakathi kwazo zonke izifihla-buso ivame ukukhuthaza ukukhula kwamagciwane, kodwa akuzona zonke lezi zinambuzane ezincane eziyingozi.
Imvubelo nesikhunta
USolwazi Chen Weining, uMqondisi weFood Technology Programme eNanyang Technological University, engxoxweni wathi:
Ngenxa yokuba khona kwama-microorganisms endaweni esizungezile kanye nesistimu yokugaya ukudla (njengomlomo namathumbu), akumangazi ukuthola lawa ma-microorganisms namagciwane kumaski.
UDkt. Li Wenjian, iDini yoMnyango Wezekhemikhali Nesayensi Yempilo e-Nanyang Technological Institute, uthe izinto ezisetshenziswa kulawa maski zingabamba inani elithile lamagciwane ngemva kwamahora ayishumi nambili okusetshenziswa.
Uveze ukuthi umehluko omkhulu phakathi kwezifihla-buso ezingalukiwe ezilahlwayo nezingasetshenziswa kabusha yindwangu yolayini eseduze nomlomo. Wathi:
Indwangu yolwelwesi eseduze nomlomo yilapho amagciwane ehlala khona lapho sithimula noma sikhwehlela. Uma sigqoka imaskhi futhi sikhuluma, amathe ethu ayoba athomu futhi anamathele kule ndwangu
UDkt. Li wengeze ngokuthi uma kuqhathaniswa namamaski alukiwe angasetshenziswa kabusha, imaski engalukiwe alahlwayo inganikeza ukuphefumula okungcono kanye nomsebenzi wokuhlunga amagciwane. Isikhala sefayibha yamamaski alukiweyo sikhulu ngokuqhathaniswa, ngakho ukusebenza kokuhlunga kwebhaktheriya akukuhle kangako.
Ngakho-ke, uma imaski engasetshenziswa kabusha ingahlanzwa njalo, ingabangela uthuli, ukungcola, umjuluko, nezinye izinambuzane ezincane (kuhlanganise namabhaktheriya) ukunqwabelana ngaphakathi nangaphandle kwemaski.
Lokhu kungenzeka kubangele ukungezwani komzimba nezinto ezithile, ukucasuka kwesikhumba, noma izifo.
UDkt. Chen, uprofesa osizayo eMnyangweni weMicrobiology kanye ne-Immunology e-Yang Luling Medical College yase-National University of China, utshele izintatheli ukuthi “ezimweni eziningi”, amagciwane kumaski awabangeli imiphumela emibi kakhulu, kodwa ngezinye izikhathi “izifo ezingosomathuba” zingase zenzeke.
Imaski engcolile engakahlanzwa isonto lonke
Lawa mabhaktheriya enza i-parasitize esikhumbeni angaphindaphinda kakhulu kumaski angcolile futhi abangele izifo. UDkt Chen wathi:
Lapho inani lamagciwane liphansi, amasosha omzimba azowalawula. Uma inani seliphezulu, lingase libangele ukungezwani komzimba okumaphakathi kuya kokubi kakhulu, izinkinga zokuphefumula, kanye nezifo emakhaleni.
UDkt Chen uveze ukuthi kunzima ukunquma ukuthi amabhaktheriya ayingozi ahlala kumaski, ngakho-ke kunconywa ukuthi abantu bahlale behlanza imaski yabo noma bawageze ngemva kokuwagqoka usuku.
Ingabe usalokotha ukuyekethisa futhi ungashintshi kumaski angalukiwe lapho ubona lawa magciwane “abonakala ngokuzumayo” kumaski?
I-Dongguan Liansheng Non woven Technology Co., Ltd.yasungulwa ngoMeyi 2020. Kuyibhizinisi elikhulu lokukhiqiza indwangu engalukiwe ehlanganisa ucwaningo nentuthuko, ukukhiqiza, nokudayiswa. Ingakwazi ukukhiqiza imibala ehlukahlukene ye-PP spunbond izindwangu ezingalukiwe ezinobubanzi obungaphansi kwamamitha angu-3.2 ukusuka ku-9 amagremu kuya ku-300 amagremu.
