Qhov sib txawv tseem ceeb ntawm cov kab mob thiab cov kab mob yog cov kab mob yog cov kab mob microscopic prokaryotes nyob thoob plaws thaum cov kab mob parasites yog cov kab mob uas nyob hauv lossis hauv lawv cov tswv thaum ua rau muaj kab mob rau cov tswv.
Parasite thiab kab mob yog cov kab mob uas zoo li cov kab mob qub heev tab sis muaj kev hloov pauv zoo rau kev ciaj sia nyob rau hauv ib puag ncig sib txawv. Rau tib neeg, cov kab mob no tseem ceeb heev vim tias feem ntau ntawm tib neeg kis tau los ntawm lawv. Qee zaum, qee cov kab mob raug suav tias yog kab mob cab.
Pab yog dab tsi?
Parasitism yog ib hom kev sib koom ua ke uas cov kab mob tau txais txiaj ntsig thaum ua phem rau tus tswv tsev. Yog li, parasites ua rau muaj kab mob rau cov hom tsiaj. Yog hais tias ib tug kab mob nyob rau hauv los yog nyob rau hauv ib tug tswv tsev thaum tau txais cov as-ham los ntawm tus tswv tsev, tus kab mob no txhais tau tias yog parasite. Parasites tuaj yeem ua tau ntau lub cell lossis unicellular thiab feem ntau me dua lawv cov tswv. Piv txwv ntawm cov kab mob unicellular muaj xws li ntau yam kab mob thiab cov kab mob fungi, thiab cov kab mob ntau yam muaj xws li zuam, nab, thiab qee yam kab mob (Helminthes).
Daim duab 01: Parasite
Tus yam ntxwv tseem ceeb ntawm cov kab mob muaj raws li hauv qab no:
- Kev nkag mus rau lub neej yooj yim thiab nyuaj
- Koom nrog ob lossis ntau tus tswv
- Qhia ob qho tib si kev sib deev thiab kev sib deev hloov pauv
Raws li qhov chaw nyob, muaj ob hom kab mob cab; endoparasites thiab ectoparasites. Endoparasites nyob hauv lub cev ntawm lawv tus tswv, thiab ectoparasites nyob rau sab nrauv lossis hauv cov ntaub so ntswg ntawm tus tswv. Cov tswv yog ob hom; (a) tus tswv tsev, qhov twg kev sib deev ntawm cov kab mob tshwm sim, thiab (b) tus tswv tsev nruab nrab, qhov chaw yug me nyuam ntawm tus kab mob tshwm sim.
Cov kab mob yog dab tsi?
Cov kab mob yog cov kab mob keeb kwm yav dhau los ntawm unicellular prokaryotes nrog ntau haiv neeg. Thawj cov kab mob tshwm sim txog 3.5 billion xyoo dhau los. Txij li cov kab mob muaj ntau hom kab mob sib txawv, lawv nyob hauv yuav luag txhua qhov chaw nyob (txawm tias nyob hauv qee qhov chaw nyob) hauv ntiaj teb. Cov kab mob tsis muaj lub hauv paus txheej txheem. Tsis tas li ntawd, lawv muaj ib qho chromosome uas muaj DNA. Tsis tas li ntawd, cov kab mob hauv cov kab mob tsis muaj cov kab mob sib txuas ua ke xws li endoplasmic reticulum, Golgi apparatus, lysosomes, mitochondria, micro-filaments, microtubules, thiab centrosomes. Tsis tas li ntawd, cov kab mob cell phab ntsa muaj cov khoom tshwj xeeb hu ua peptidoglycan, uas yog polymer.
Daim duab 02: Cov kab mob - E. coli
Thaum xav txog cov duab ntawm cov kab mob, lawv pom peb cov duab yooj yim: bacillus, coccus, thiab spirillum. Ntau cov kab mob muaj ntau hom appendages nrog rau flagella thiab pili, uas pab lawv nyob rau hauv locomotion. Gram staining yog cov txheej txheem feem ntau siv los txheeb xyuas cov kab mob. Raws li cov stain no, cov kab mob tuaj yeem yog gram-positive lossis gram-negative. Binary fission yog hom tseem ceeb ntawm asexual reproduction pom nyob rau hauv cov kab mob.
Cov kab mob yog cov kab mob tseem ceeb rau tib neeg vim qee qhov ua rau tib neeg muaj kab mob thiab qee qhov muab txiaj ntsig xws li nitrogen fixation, genetic engineering, decomposition, thiab bioremediation, thiab lwm yam. Qee qhov piv txwv ntawm cov kab mob ua rau muaj kab mob Vibrio cholera, Corynebacterium diphtheria, Helicobacter pylori, thiab Rickettsia Typhi. Qee cov kab mob yog kab mob cholera, diphtheria, peptic ulcers, thiab typhus, thiab lwm yam.
Dab tsi yog qhov zoo sib xws ntawm Parasite thiab Bacteria?
- Qee hom kab mob raug suav hais tias yog kab mob cab.
- Yog li ntawd, cov kab mob cab thiab kab mob ua rau cov kab mob hauv tib neeg, lwm yam tsiaj thiab nroj tsuag.
- Ob pawg muaj xws li cov kab mob microscopic.
- Ntxiv mus, ob pawg suav nrog cov kab mob unicellular.
- Lawv muaj nyob hauv ntau hom chaw nyob.
- Parasites thiab qee cov kab mob nyob hauv kev sib raug zoo nrog lwm tus kabmob.
Dab tsi yog qhov txawv ntawm Kab Kab Mob thiab Kab Mob?
Ib tug kab mob yog ib yam kab mob uas nyob hauv lwm yam kab mob hu ua tus tswv tsev. Hauv qhov sib piv, cov kab mob yog cov kab mob me me uas yog prokaryotic thiab ubiquitous. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm cov kab mob thiab cov kab mob. Thaum xav txog lawv lub koom haum ntawm tes, cov kab mob tuaj yeem yog unicellular lossis multicellular thaum tag nrho cov kab mob yog unicellular, Qhov no yog lwm qhov sib txawv ntawm cov kab mob thiab cov kab mob. Ntxiv mus, txhua tus kab mob ua rau lawv tus tswv tsev thiab muab cov khoom noj los ntawm lawv cov tswv thaum cov kab mob feem ntau tsis muaj mob.
Cov duab hauv qab no qhia txog qhov sib txawv ntawm cov kab mob cab thiab kab mob.
Summary – Parasite vs Bacteria
Ib tus kab mob parasite yog ib yam kab mob uas nyob hauv lossis hauv lwm lub cev, muab cov khoom noj thiab ua rau tus tswv tsev. Nyob rau hauv sib piv, cov kab mob yog prokaryotic unicellular microscopic kab mob nyob txhua qhov chaw. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm cov kab mob thiab cov kab mob. Parasites ib txwm ua phem rau lawv cov tswv thaum qee cov kab mob ua rau mob lossis kab mob. Tsis tas li ntawd, qee cov kab mob parasites tsis yog microscopic. Ntxiv mus, ib txhia ntawm lawv yog eukaryotic thiab multicellular. Qhov no qhia txog qhov sib txawv ntawm cov kab mob cab thiab kab mob.
