Cov "intruders" no nyob txhua qhov chaw, tab sis tsis txhob ntshai.

Txhua square centimeter ntawm daim tawv nqaij harbors txog 100 txhiab microorganisms. Thaum peb txham, cov kua dej nrog cov kab mob thiab cov kab mob tawg yuav luag ib 'meter'.

Philip Tierno, kws kho mob microbiologist ntawm New York University hais tias "Lub neej ntawm cov kab mob nyob ntawm ntau yam," hais. - Cov kab mob yuav tsum nkag mus rau hauv lub cell ntawm lwm yam kab mob kom rov tsim dua. Yog li ntawd, sab nraud ntawm nws, lawv nyob tsawg dua cov kab mob. Txawm hais tias lawv tseem muaj sia nyob ntawm ntau qhov chaw hauv tsev. Cov kab mob tuaj yeem sib kis tau sab nraum lub cev, yog li lawv nyob ntev dua."

Lub neej ntawm microbes cuam tshuam los ntawm cov av noo thiab kub.

Tsis muaj kab mob lossis kab mob yuav muaj sia nyob ntawm qhov chaw qhuav nrog tsawg dua 10% noo noo. Lawv ua kom nquag plias nyob rau hauv lub xub ntiag ntawm tej as-ham: khoom noj khoom haus, hlwb hlwb, ntshav, mucus. Yog li ntawd, daim txhuam cev ntxuav tais diav yog ib qho av fertile rau lub neej ntawm cov kab mob.

Cov kab mob mesophilic, xws li tuberculosis-ua rau Koch's bacillus, zoo tshaj plaws nyob rau hauv chav tsev kub. Yog li ntawd, lawv nyob ntev dua li txias-hlub los yog thermophilic microorganisms. E. coli ntawm chav tsev kub thiab cov av noo ib txwm nyob ntawm ob peb teev mus rau ib hnub. Cov kab mob no tuaj yeem pom hauv cov nqaij minced thiab ua rau cov zaub mov lom. Tus kab mob calicivirus, uas ua rau mob plab hnyuv, nyob rau hnub lossis ntau lub lis piam. Tab sis HIV nyob rau hauv qhib huab cua tuag yuav luag tam sim ntawd.

Txhawm rau kom muaj sia nyob tsis zoo, qee cov kab mob ua rau lub plhaub ntom ntom.

Cov kab mob no hu ua spore. Nyob rau hauv daim ntawv ntawm spores, cov kab mob tiv taus huab cua kub thiab av noo.

Piv txwv li, cov kab mob Staphylococcus aureus, uas ua rau muaj kev phom sij-tshuaj lom, noj tshuaj lom thiab kis kab mob, ua li no. Staphylococcus spores muaj sia nyob ntawm cov khaub ncaws qhuav rau ob peb lub lis piam, pub rau cov tawv nqaij uas seem, Tierno tau hais. Thiab anthrax bacillus, tus neeg sawv cev ntawm anthrax, nyob rau hauv daim ntawv ntawm spores rau kaum thiab ntau pua xyoo.

Tab sis tsis txhob ntshai. Txhawm rau tiv thaiv koj tus kheej, ntxuav koj txhais tes ntau zaus. Qhov no zoo heev txo qhov kev pheej hmoo ntawm kev cog lus ib yam dab tsi. Siv cov tshuaj tua kab mob kom tsis tu ncua los so tej qhov chaw uas muaj kev phom sij: cov qhov rooj, rooj noj mov, dab dej.
