Gram-zoo kab mob

Gram-zoo kab mob tau txais nws lub npe rov qab nyob rau hauv 1884, thaum lub Danish paub txog G. gram muaj nws txoj kev tshawb xyuas. Lub hauv paus ntawm txoj kev no yog tso cia tseg ntawm lub cell phab ntsa ntawm cov kab mob tshwj xeeb dyes uas tso cai rau kom paub tias cov biochemical thaj chaw ntawm lub cell week. Muaj pes tsawg leeg ntawm cov tshuaj, uas ua coloration muaj xws li aniline thiab iodine tov rau kho cov xim. Gram zoo kab mob tom qab ntxuav lub tsuas xav thiab Gram - sis tsuas kob.

Gram-zoo kab mob muaj xws li laktobatsillobakterii, micrococcal kab mob batsillobakterii thiab klostridiobakterii. Tus qauv ntawm txhua pab pawg neeg yog txawv cov kab mob tau los yog impossibility ntawm sporulation, tab sis nyob rau hauv kev lawv yog raug - muaj ib tug membrane thiab ribosomal nucleotide.

Clostridia, lawv yog feem ntau anaerobes thiab feem ntau yog nyob rau hauv daim ntawv ntawm nrog, tab sis tej zaum cocci. Thaum lub sij hawm tsim ntawm cov kab mob noob Clostridium muaj ib tug txiv qaub lawm. Clostridium muaj lub peev xwm mus ua unrest nyob rau hauv ib co cov nqaijrog, polysaccharides, amino acids thiab Pirin. Piv txwv li, ib tug fermentation txheej txheem siv Clostridium tau acetone thiab ib co lwm yam alcohols. Cov kab mob no muaj peev xwm nyob rau hauv cov av, nyob rau hauv cov dej, cov hnyuv ntawm nyob quavntsej. Rau tib neeg txaus ntshai Clostridium tetanii (yav tetanus), thiab Clostridium septikum (causative tus neeg saib xyuas ntawm cov pa roj gangrene). Tus kab mob yog Clostridium Kab mob Botulinum, ua ib tug haib tshuaj lom uas ua rau yus instantaneous tuag.

Batsillobakterii yog pas nrig-zoo li tus feem ntau, Aerobic, lawv muaj peev xwm ntawm txoj kev noob. Bacillus subtilis yog zoo tshaj plaws paub tias cov no subspecies, uas yog kev koom tes nyob rau hauv tus txheej txheem ntawm decomposition ntawm cov organic teeb meem. Rau cov txiv neej yog yus Bacillus anthracis. Vim lub ntuj zog batsillobakterii siv los tsim tshuaj tua kab mob.

Lactobacillus - ib tug kab-zoo kab mob uas tsis noob thiab muaj nyob rau hauv daim ntawv ntawm cov sticks. Tus nqi ntawm cov kab mob yog lawv muaj peev xwm mus ferment carbohydrates thiab npaj los ntawm lactic acid. Lactobacilli yuav muaj nyob rau hauv cov dej, khoom noj siv mis, pickled qhwv, pickled. Lawv tsim thaum lub sij hawm ensiling raws li ib tug tshwm sim ntawm decomposition ntawm nroj tsuag thiab tsiaj seem.

Micrococci ua ke ob leeg aerobic thiab co kab mob uas tsis tsim endospores. Metabolism hauv no feem ntau yog aimed ntawm cov txij nkawm uas ua pa muaj nuj nqi. Cov cocci yog muab kev koom tes nyob rau hauv tus txheej txheem ntawm decomposition ntawm khoom noj khoom haus, tsiaj thiab cog nyob. Lub nto moo tshaj plaws tus neeg sawv cev ntawm micrococci - aureus. Yog hais tias nws tau txais rau cov khoom uas muaj nyob rau hauv tshav kub, ces nws pib los mus raws taug, txaus ntshai rau tib neeg.

Apart sawv mycoplasma, ib co kev uas yog tseem txais kab-zoo kab mob. Mycoplasma - qhov tsawg tshaj plaws pre-nuclear, kom lawv tsis txhob muaj ib tug membrane, tsis noob. Feem ntau ntawm lawv yog harmless, tab sis ib txhia pathogens tej zaum yuav, piv txwv li, ib tug neeg yuav ua kab mob rau ob leeg tsiav tshuaj, urogenital kabmob, txheej week thiab ua pa ib ntsuj av. Thaum coloring los ntawm cov Gram txoj kev, tsis yog txhua txhua ntawm lawv muaj peev xwm nrees tuav cov xim.

Tus txiv neej yog nyuaj heev "kom tau raws" nrog rau cov Gram-zoo kab mob. Kev tshawb fawb qhia tau tias txog ib nrab ntawm tag nrho cov kab mob nyob rau hauv tib neeg tshwm sim los ntawm tus neeg sawv cev ntawm no pab pawg neeg. Thaum zoo muab cov khoom thiab tus kheej kev tu cev tau uas tsis yog-conflictual zej zog yog siab txaus. Tab sis lub allergic ntawm lub cev, ib txhia Gram-zoo kab mob muaj peev xwm ntxias loj teeb meem. Nyob rau hauv cov ntaub ntawv no, mus rau cov kev pab ntawm ib tug tshwj xeeb cov pab pawg neeg ntawm tshuaj tua kab mob, uas thuam cov kab mob.
