Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Chinokonzera TB zvikurukuru iMycobacterium tuberculosis (MTB), utachiona huduku, hunoita mhepo, husingafambi. Kuwanda kwemafuta emuviri wechirwere ichi ndiko kunoita kuti chirwere chacho chive nemakemikari akasiyana nemamwe. Rinopatsanuka pashure pemaawa 16 kusvika ku20, rinova danho rinononoka zvikuru kana richienzaniswa nemamwe mabhakitiriya, ayo anowanzopatsanuka mukati meawa isingasviki imwe. Mycobacteria ine membrane yekunze lipid bilayer. Kana kunhuwa kweGram kukaitwa, MTB inonhuwa zvishoma "Gram-positive" kana kuti haichengeti dhayi somugumisiro wepamusoro ye lipid uye mycolic acid ye cell wall yayo. MTB inogona kutsungirira mishonga isina simba yokuuraya utachiona uye kurarama mumamiriro ezvinhu akaoma kwevhiki. Muzvisikwa, utachiona hunogona kungokura chete mumasero echikara, asi M. tuberculosis inogona kukudziridzwa murabhoritari. Vachishandisa mavara eganda pamasampuli anobuda mumhino (anonziwo "sputum"), masayendisiti anogona kuziva MTB pasi pemicroscope. Sezvo MTB inochengeta mavara akati kunyange pashure pokurapwa nomushonga une acidic, inorondedzerwa sebhakitiriya ine acid-fast. Nzira dzinowanzoshandiswa pakusvibisa tsvina neacid-fast dzinoshandiswa neZiehl<unk>Neelsen uye neKinyoun, idzo dzinoita kuti tsvina neacid-fast dziite ruvara rutsvuku runoita kuti munhu aone zviri nani kana aine ruvara rwebhuruu. Auramine-rhodamine staining uye fluorescence microscopy zvinoshandiswawo.  Mubvunzo: Ndedzipi dzimwe acid dzinoshandiswa?
