Mushure mokunge majekiseni aya aitwa, MTB inoita "Gram-positive" kana kuti haichengetedzi dhayi semugumisiro wepamusoro we lipid uye mycolic acid ye cell wall yayo. MTB inogona kumira nemishonga isina simba yekuuraya utachiona uye inopona mumamiriro akaoma kwemavhiki. Muzvarirwo, bhakitiriya inogona kungogara mukati memasero emurwere, asi MTB inogona kuonekwa murabhoritari. Kushandisa mazhinji ezvirwere zvechirwere ichi kwakanyanya kunonoka kana ichienzaniswa nemamwe mabhakitiriya, ayo anowanzo govana mune isingasviki awa. Mycobacteria ine yekunze membrane lipid bilayer. Kana Gram staining ikaitwa, MTB inochera "Gram-positive" kana kuti haichengetedze dhayi semhedzisiro yeiyo yakakwira lipid uye mycolic acid ye cell wall yayo. MTB inogona kumira nemishonga isina simba yekuuraya utachiona uye inopona mumamiriro akaoma kwemavhiki. Muzvarirwo, bhakitiriya inogona kungokura mukati memasero emurwere, asi MTB inogona kuonekwa mur
