Mycobacterium lefuba: litšobotsi tse ya data microorganisms

Mycobacterium lefuba (Koch o bacillus) - a mob mobile ea HIV molamu e bōpehileng joaloka libaktheria tse ka theha khoele-joaloka sebopeho. Ba acid e manganga le ntse ba le e ngata lipid le boka ba linotši ka leboteng lona, e leng qeto hanyetsa bona ho dezveschestvam, khanya ea letsatsi kapa omisa. microorganisms tsena ke tse mpe li 'mala le lidae aniline le ho hlokomela pathogenicity phahameng le hydrophobicity.

Re lokela ho hlokomela hore bana ba khethehileng mefuta morphological ea libaktheria tse coccoid sebopeho le lintho tse L, le hoja boholo ba bona ba - e tšesaane le otlolohileng le melamu hanyenyane kobehileng. Ho feta moo, Mycobacterium lefuba di na le dipegelo ka cytoplasm fofa khoahlapisitseng (granules itseng acid e labile).

Ha re bua ka setso thepa ea libaktheria tsena, ba facultative anaerobes kapa aerobes. bath tsobotsi bona - kgolo ya lieha haholo, 'me ho hlokahala hore protheine le glycerin ho ikatisa atlehileng. Mecheng ea litaba mokelikeli, microorganisms tsena theha holim filimi. Ka le letšo-letšo phepo buisanang Mycobacterium lefuba foromo ho ikatisa ya omileng wrinkled patina remereme mmala, ponahalo ea likolone tsa bona li tšoana le ho cauliflower.

makgetheng pathogenetic

Ntlha e ka sehloohong ea pathogenicity - "Thapo Ntho e". Ho glycolipids, e sireletsa Koch bacillus ke phagocytosis, 'me beha dinama tse nyenyane tse nang le chefo e senya le mamello batho. Ho lokela ho hlokomeloe hore ho M. lefuba rarahaneng ba tšoauoa ka sete ya antigens, kahoo boitsebiso bona e hoo e ka bang mohla sebediswa bakeng sa thepa antigenic.

Hore na lefuba a tšoaetsanoang? Mafu a Hlahang ka lefu lena ke mekhoa e meraro ea phetiso. Ho airborne, liphoofolo le tšoaetso ka tsela lebese (alimentary) le lerōle airborne. E lokela ho ile a bolela hore motho a ho pholletsa le bophelo ba hangata ha ho kopana le baemeli ba ea lefuba, empa lefu lena ha e ntshetsa pele ka nako e tšoanang, ho itšetlehile ka ho hanyetsa ea phelang.

bacillus Koch hangata phunyeletse ka pampitšana ho hema, e leng ba haptjoa ke macrophages ena. Ho ekelletsa moo sebakeng sa ingress ea libaktheria thehoa bronhopnevmonichesky tsepamisa, e le ho ruruha ha nodes lebatowa lisele tsa mmele. Mohloli o ka sehloohong oa tshwaetso ka mo lakalisa serame sa matšoafo le generalization ke lefuba. Ka ho hanyetsa phahameng ea phelang Mycobacterium khaotsa ho ikatisa. Ka nako e tšoanang, ba ile ba nako e telele lule 'mele' me ka butswe ka haholo a lilemo.

Ke lokela ho bolela hore ba bonoa pele tsa lefuba eketsa menyetla ea qeto e molemo ka lefu lena. Kajeno ba ka ho eketsehileng ho sebelisa mekhoa e morao-rao tekotshupo, har'a tse sebakeng se ka sehloohong e lula e polymerase ketane itšoara joang.

Ha PCR hloleha ho lemoha TB bacillus Koch DNA esita le tabeng ea chelete bonyane hore netefatsa ntshetsopele ya lefu lena le ke ke ba ka tsela leha e le efe. Ho phaella moo, PCR ke ho le bonolo ho lemoha mycobacteria hanyetsa lithethefatsi ka bomong. Ho lekaneng ho tšoara ho fihlela ka liphatsa tsa lefutso e na le boikarabelo ba ho hanyetsa baktheria ho rifampicin, isoniazid kapa ntho e fapaneng lithethefatsi, e le hore nka lihora tse ka tlaase ho 48.
