Duba wurin da ke ƙasa sannan ka amsa tambayar daga baya a cikin harshe ɗaya kamar yadda wurin yake:  Passage: Babban reshe na ilimin ƙwayoyin cuta shine rarraba ƙwayoyin cuta. Ana iya rarraba ƙwayoyin cuta gwargwadon ƙwayoyin da suke kamuwa da shi: ƙwayoyin dabbobi, ƙwayoyin cuta, ƙwayoyin cuta, da bacteriophages (ƙwayoyin cuta da ke kamuwa da ƙwayoyin cuta, waɗanda suka haɗa da ƙwayoyin cuta mafi rikitarwa). Wani rarrabuwa yana amfani da sifar geometrical na capsid ɗin su (sau da yawa helix ko icosahedron) ko tsarin ƙwayoyin cuta (misali kasancewar ko babu labulen lipid). Kwayoyin cuta suna da girman daga kimanin 30 nm zuwa kimanin 450 nm, wanda ke nufin cewa yawancin su ba za a iya gani da microscopes na haske ba. An yi nazarin siffa da tsarin ƙwayoyin cuta ta hanyar microscopy na lantarki, NMR spectroscopy, da X-ray crystallography.  Tambaya: Wace microscopy ake amfani da ita don nazarin siffa da tsarin ƙwayoyin cuta?
