Odokotela base-Australia baqhuba isifundo lapho amathuba okulimala kwesiguli asebenza ngenxa yamagesi amathumbu avela kubasebenzi bezokwelapha. Kwavela ukuthi ubungozi bokuthi umphumela okhulisa izingane ancike ezimweni ezithile ezihambisana nale nqubo.
Iphuzu lokuqala lolo cwaningo lwaluwumbuzo womunye wabahlengikazi base-Australia abamnikezwe ngo-2001 kumphathi wakhe kudokotela ohlinzayo. Ummeleli wabasebenzi bezokwelapha, uvame ukubamba iqhaza ngqo ekusebenzeni, ubuze amathuba okulimaza isiguli ngenxa yokungcola kwamagesi amathumbu avela ngqo egumbini lokusebenza ngqo egumbini elisebenzayo. Ngokweqiniso, inqubo enjalo ingabangela ama-microgenic ama-microoorganisms ahlukaniswa nabasebenzi bezokwelapha, lapho kuvulwa isilonda sesiguli, futhi, ngokufanele, ibangela i-sepsis yokugcina. Kuyaqapheleka ukuthi udokotela ohlinzayo wayengazi ukusabela okusebenzayo kombuzo onikeziwe, ngakhoke waxhumana nenye yezazi ze-microbiologists ezigunyaziwe ezisebenza eCanberra (Australia). Isazi sanquma ukubamba isilingo esisebenzayo futhi sacela omunye ozakwabo ukuthi acindezele ngqo esitsheni se-petri ngebanga elifushane kakhulu - amasentimitha amahlanu. Ngasikhathi sinye, umhlanganyeli wesipiliyoni wenza isenzo esihlongozwayo kuqala ezingutsheni, bese ngaphandle kwawo. Ngemuva kokuthi ukuhlolwa sekuqediwe, zombili izitsha ze-Petri zasala ubusuku bonke, ukuze kuqinisekiswe ukukhiqizwa kwamagciwane afanele ngokwengeziwe. Umphumela wakhombisa ukuthi idivaysi yokuhlangenwe nakho lapho kukhiqizwa khona impisi lapho kukhiqizwa khona izingubo, ngakusasa bekuhlanzekile ngokuphelele, okufakazele okungenakwenzeka okusebenzayo ukulimaza abasebenzi bezokwelapha lapho kukhishwa amagesi amathumbu.
Kuyaphawuleka ukuthi esitsheni se-petri, umbhikisho ongenayo wenziwa ungakaze ushaywe yiPhasikemende Engemuva, kusekhona izinhlobo ezimbili zamagciwane avame ukuba khona emathunjini nasosikhumba somuntu. Kodwa-ke, njengoba abaphenyi baphawula, izingozi zokuchitha imfucumfucu kangaka ukuze isiguli ngeke zikwazi ukuzithoba emsebenzini, ngoba abasebenzi bezokwelapha benza umsebenzi wawo ngaso sonke isikhathi enza umsebenzi wawo ezimpamba.
