Abaganga ba Australiya bakoze ubushakashatsi aho bishoboka ko ibyangiritse ku murwayi bikozwe biturutse ku myuga y'ubuvuzi. Byaragaragaye ko ibyago byo gutoranya biterwa nibihe bimwe bifitanye isano nibikorwa.
Intangiriro yo kwiga ni ikibazo cya umwe mu baforomo bo muri Ositaraliya bamuhaye mu 2001 ku muyobozi we kubaga. Uhagarariye abaganga, akenshi yakira uruhare mu buryo butaziguye mu bikorwa, yabajije bishoboka ko umurwayi yari afite kubera imyanda y'igihe kuva mu cyumba cyo mu mara. Ubuntu, inzira nkiyi irashobora gutera mikorobe ya pathogenic itandukanye nabashinzwe ubuvuzi, mugukingura igikomere cyumurwayi, kandi, kubwibyo, bitera Sepsis ya nyuma. Birakwiye ko tumaze kubona ko umuganga utazi igisubizo gifatika ku kibazo runaka, ni cyo cyatumye umwe mu Microbiologiste yemewe wakoraga muri Canberra (Ositaraliya). Impuguke yahisemo gukora ubushakashatsi bufatika maze abaza umwe muri bagenzi be kugirango basunike mu buryo butaziguye icyogajuru kigufi - santimetero eshanu. Muri icyo gihe, abitabiriye uburambe bakoze ibikorwa byateganijwe mbere mu myambaro, hanyuma bitabaye. Nyuma yubushakashatsi burangiye, ibiryo bya Petri byombi byari bisigaye ijoro ryose, kugirango habeho byoroshye kubyara bya bagiteri. Igisubizo cyerekanaga ko igikoresho cyuburambe aho bubbing yakozwe mumyenda, bukeye bwaho byari bifite isuku rwose, byagaragaye rwose ko bidashoboka kwangiza umurwayi hamwe nabashinzwe ubuvuzi mugihe imyuka yo hanze yasohotse.
Birashimishije kubona mu isahani ya Petri, bubbing yakozwe n'inyuma, haracyari ubwoko bubiri bwa bagiteri busanzwe buboneka mu mara no ku ruhu rw'abantu. Ariko, nkuko abashakashatsi bagaragaje, akaga ko guta imyuka ku murwayi ntigishobora kugashyikiriza imirimo, kubera ko abakozi b'ubuvuzi bahora bakora imirimo yayo mu myanya yashyizwe mu bikorwa byashyizwe mu bikorwa by'imikorere yashyizwe mu bikorwa byayo.
