Oogqirha base-Australia baqhuba isifundo ngexesha lokuphathwa komonakalo kwisigulana esisebenza ngenxa yeegesi zamathumbu ezivela kubasebenzi bezonyango. Kwavela ukuba umngcipheko wokongeza ukuqulwa komntu uxhomekeke kwiimeko ezithile ezinxulumene nale nkqubo.
Indawo yokuqala yesifundo yayingumbuzo womnye wabahlengikazi wase-Australia wanikwa yena ngo-2001 kwisuphavayiza yakhe kugqirha wakhe. Ummeli wabasebenzi bezonyango, edla ngokubangela ukuba bathathe inxaxheba ngokuthe ngqo kwimisebenzi, babuza ukubakho kwengozi kwisigulana ngenxa yenkunkuma yexesha elithile kwigumbi lokusebenza. Ithiyori, le nkqubo enjalo inokubangela ukuba i-microorganic microorganis ye-pitogenic ehlulekileyo yabasebenzi bezonyango, ekuvuleni inxeba lesigulana, kwaye, kubangela le ndawo yokugqibela. Kufanelekile ukuba uqaphele ukuba ugqirha ongugqirha wayengazi impendulo ebonakalayo kumbuzo onikiweyo, ke ngoko waqhagamshelana nomnye wama-microbiogists ogunyazisiweyo asebenze eCanberra (Australia). Ingcali ithathe isigqibo sokubamba uvavanyo olusebenzayo kwaye icele omnye wabasebenzi bakhe ukuba atyhalele ngqo kwi-perit yesitya se-peri ene-petrimes emfutshane - iisentimitha ezintlanu. Kwangelo xesha, umthathi-nxaxheba amava enze isenzo esicetywayo kuqala kwimpahla yokunxiba, kwaye ngaphandle kwawo. Emva kokuba kugqityiwe kugqityiwe, zombini izitya zepetriki zashiywa ngobusuku, ukuqinisekisa ukuveliswa ngokuchanekileyo kwentsholongwane. Isiphumo sabonisa ukuba isixhobo samava apho i-bubbang yaveliswa khona kwimpahla yokunxiba, ngentsasa elandelayo yayicocekile, eqinisekisile ukuba akukho sigulana esisebenzayo sokwenzakalisa isigulana kubahlobo amalungu akhutshwayo.
Kuyaphawuleka ukuba kwisitya se-petri, ityhubhu eyenziwa yangaphantsi ye-PARR PASS, kusekho iintlobo ezimbini zentsholongwane ezihlala zikho kumathumbu nakwisikhumba somntu. Nangona kunjalo, kuba abaphandi baphawula, iingozi zenkunkuma yegesi ukuze isigulana asinakho ukuthobela umsebenzi, kuba abasebenzi bezonyango bahlala besebenza kwi-selferwear.
