D'Hérelle akataura kuti yaive biology inoramba ichibereka, neimwe nzira ichidya mabhakitiriya. Vamwe, Nobelist Jules Bordet mukuru pakati pavo, vakafungidzira kuti ma phage aive makemikari asina hupenyu, kunyanya ma enzymes, ayo aive atovepo mumabhakitiriya, uye anongokonzeresa kuburitswa kwemapuroteni akafanana, achiuraya mabhakitiriya mukuita. Nekuda kwekusava nechokwadi uku, uye d'Herelle achishandisa ma phage pasina kuzeza kukuru pavanhu, basa rake raive pasi pekurwiswa nguva dzose kubva kune vamwe vazhinji vesaenzi. Yakanga isiri kusvikira phage yekutanga yaonekwa pasi pe electron microscope naHelmut Ruska muna 1939 kuti hunhu hwayo hwechokwadi hwakagadzwa. Mubvunzo waive wekuti D'Herelle aisatora zvakakomba nevaaishanda navo?
kushandisa ma-phage pasina kuzengurira kukuru pavanhu
