Mycobacterium tarin fuka: halaye data microorganisms

Mycobacterium tarin fuka (Koch ta bacillus) - gram-tabbatacce sanda-dimbin yawa kwayoyin wanda zai iya samar da thread-kamar tsarin. Su acid-resistant kuma har yanzu dauke da wani yawa na sia kakin zuma a bango, wanda kayyade su jure dezveschestvam, hasken rana ko bushewa. Wadannan kwayoyin suna bad an canza launin tare da aniline dyes da kuma gano high pathogenicity da hydrophobicity.

Ya kamata a lura da cewa wadannan na musamman morphological iri kwayoyin ne coccoid tsarin da kuma L-siffofin, ko da yake mafi yawan su - shi ne na bakin ciki da kuma mike kuma dan kadan mai lankwasa sanduna. Bugu da ƙari kuma, Mycobacterium tarin fuka dauki kashi a cytoplasm Fly hatsi (takamaiman granules acid labile).

Idan muka magana game da al'adun Properties na wadannan kwayoyin cuta, su ne facultative anaerobes ko aerobes. Su halayyar alama - sosai m girma, da kuma bukatar da furotin da kuma glycerin ga nasara kiwo. A cikin ruwa kafofin watsa labarai, wadannan kwayoyin samar da wata surface fim. A m gina jiki duba Mycobacterium tarin fuka a haifuwa nau'i na bushe wrinkled patina mau kirim launi, bayyanar da mazauna kama farin kabeji.

Babban factor na pathogenicity - "igiyar factor". Yana glycolipids, wanda kare Koch bacillus daga phagocytosis da kuma sanin ko za a mai guba nama lalata mutum haƙuri. Ya kamata kuma a lura da cewa, M. tarin fuka hadaddun ne halin da wani sa na antigens, don haka su ganewa ne kusan ba amfani ga antigenic Properties.

Ko da tarin fuka daukar kwayar cutar? A epidemiology da wannan cuta ne uku halaye na watsa. Shi ne Airborne, dabbobi da cutar via da madara (alimentary) da kuma Airborne ƙura. Ba dole ne a ce cewa mutum cikin rayuwar quite sau da yawa a lamba tare da jamiái na da tarin fuka, amma cutar ba ci gaba a lokaci guda, dangane da juriya da kwayoyin.

Koch ta bacillus sau da yawa shiga ta hanyar da numfashi fili, wanda aka kama da macrophages. Bugu da ari, a wurin ingress na kwayoyin kafa bronhopnevmonichesky mayar da hankali, a matsayin kumburi yankin Lymph nodes. A farko tushen kamuwa da cuta iya fararwa ciwon huhu da kuma hakan na da tarin fuka. A wani babban juriya da kwayoyin Mycobacterium gushe haifa. A lokaci guda, suka dogon zama a cikin jiki da kuma za a iya kunna ta hanyar mai yawa da shekaru.

Dole ne in ce cewa farkon ganewa na tarin fuka qara chances wani m ƙarshe da cutar. Yau suna ƙara yin amfani da latest bincike hanyoyin, tsakanin wanda manyan wuri ne shagaltar da polymerase sarkar dauki.

Lokacin da PCR kasa gane tarin fuka bacillus Koch DNA ko a cikin yanayin da mafi ƙarancin adadin da tabbatar da ci gaban da cutar ba zai iya zama wani hanya. Bugu da kari, PCR ne sauki gane mycobacteria juriya daga mutum zuwa mutum kwayoyi. Shi ya ishe rike har da kwayoyin halittu da suke da alhakin kwayan juriya ga rifampicin, isoniazid ko daban-daban miyagun ƙwayoyi abu, cewa daukan kasa da 48 hours.
