Njengoba ama-bacterium adla? Sakhiwo umsebenzi ebalulekile yamagciwane

Ama-bacterium - nezilwanyana ezincane kukhona elula. Ngokuvamile banayo cell eyodwa kuphela. Emvelweni, kukhona kokubili okuzuzisayo nokulimazayo kubantu imvelo nezilwanyana ezincane. Noma kunjalo, bona konke ukwabelana isakhiwo zazingavumi kahle futhi bengenalo usayizi encane. Ngemva kokufunda lesi sihloko, ungakwazi ukuthola ukuthi ama-bacterium ukondla, zohlobo aphefumule.

ulwazi olujwayelekile mayelana amagciwane

Ama-bacterium - superkingdom nezilwanyana ezincane prokaryotic. Namuhla sekunamabandla angaphezu kuka-nanhlanu nabameleli bayo. Ososayensi bathi empeleni ezincane kakhulu. Bacteriology - igatsha wesayensi study izilokazane ezincane aphansi.

usayizi sawo silinganiselwa 0.5-5 microns. Bonke zihlukaniswe amaqembu amabili - owumphumela futhi amaningi. Eyokuqala Kwenziwa ngokuphelele zonke izinqubo ukuthi esivela ku eziphilayo. Kuyaphawuleka ukuthi iningi motility virus.

Igama elithi "bacterium" njengenhlangano iyunithi ezimele ludabuka ezindaweni ngasekupheleni 70-yalolucwaningo kwekhulu elidlule. Ngaphambili, wakhonza lapho bekhuluma prokaryotes. Ngenxa yalokho zocwaningo ngo-1977, kwatholakala ukuthi zahlukaniswa subgroups ezimbili. Ukuze omunye wabo, futhi wasebenzisa igama elithi "ama-bacterium".

Inqubo emishinini yokuphefumula e-bacterium

Ukudlala inqubo ukuphefumula, nezilwanyana ezincane eziningi, kanye nabantu abadinga umoya-mpilo. abameleli enjalo ibizwa ngokuthi ama-aerobic. Nokho, kukhona labo amagciwane elula ukuthi akudingeki emoyeni. Oxygen lezi zidalwa ezincane - uhlobo ushevu. Igama lazo ngokwesayensi - anaerobes.

Zihlala izingqimba engenhla athukulule zenhlabathi, e ukudla namanzi. Yenza ikhono siphile ekujuleni okukhulu emhlabathini, imizimba amanzi, kanye ngqo odakeni. Kuyaphawuleka ukuthi ukuphefumula amagciwane aerobic hhayi kungaba lapho anaerobes baphile.

Akusiyo imfihlo ukuthi umsebenzi nezilwanyana ezincane kungaba lwezithelo olubangela ukubila. Ukuphefumula uhlobo lwama-bacterium provocateur le nqubo. Isibonelo okusobala kakhulu - kuyinto nemvubelo. Njengoba umphumela ukuvutshelwa yabo ukhiqiza carbon dioxide futhi amanzi.

Amandla lenyama. parasitism

Njengoba ama-bacterium adla futhi lokho parasitism? Lezi zinkinga ngokuvamile nesithakazelo hhayi kuphela emkhakheni wezinto eziphilayo, kodwa futhi nje abantu curious. Izimpendulo zale ungathola ku-athikili yethu.

Nezilwanyana ezincane lapho zidla izinto eziphilayo zihlukaniswe amaqembu amabili - saprotrophs kanye nezinambuzane. Ukusetshenziswa kuqala ukudla okusalile ezibolile, kanti eyesibili baziphilisa nezinye izilwane. Namuhla, parasitism - into lalivamile. Kwenzeka njengoba e kwala magciwane ngokwako, futhi abantu kanye nezilwane. Ngokuvamile kuba parasitism kungabangela ukugula okungathí sina.

It is ukuthi ezincane, kunezindlela ezimbili amandla ezaziwayo. eziphilayo Heterotrophic - kukhona ezincane izidalwa ezisetshenziswa ukuthuthukiswa ngomumo ndaba yalo organic. Isigaba sesibili sihlanganisa autotrophs - nezilwanyana ezincane ukuthi kukhona oludonsa ngamandla. Lokhu cyanobacterium, ama-bacterium yensimbi nesibabule amagciwane. Okokuqala zidlala indima ebalulekile enqubeni ye-photosynthesis. It cyanobacteria pose organic ngezinto wezinto ezingaphili.

eziphilayo Heterotrophic kungenziwa zihlukaniswe amaqembu amathathu: izimuncagazi, nezilwane eziphila futhi saprophytes. Njengomthetho, ama-bacterium yisinanakazana imisebenzi yabo ebalulekile emzimbeni izilwane, izinyoni, nezinhlanzi noma abantu. Bangaphinde baphile phezu kwesikhumba. Ngokuvamile ama-bacterium can yisinanakazana izitshalo. Kuyaphawuleka ukuthi amagciwane heterotrophic abakwazi ukufeza imisebenzi yalo ebalulekile ngesikhathi flora enempilo. Loku kungenteka kuphela uma kwenzeka ukuthi phezu kukhona izilonda fresh. Ngokuvamile ziba imbewu onegciwane kanye ama. Kulokhu, amagciwane adluliselwa vegetatively. Imbangela isifo esibangelwe igciwane kungaba imvula noma ukuthambisa yokufakelwa. Lesifo ezivamile yizinambuzane, izibungu futhi izinyoni. Kubantu, parasitism kungabangela isifo sofuba, umkhuhlane, isifo sohudo, ikholera nezifo.

Eziphila futhi saprophytes

Saprophytes - bacterium adla izinto ezifile. Bona kukhishwe micronutrients asendabeni ezingaphili, bese kwesokunxele khona uketshezi. Ziba izinto siphela.

Eziphila - amabhaktheriya esifo ezingavikelekile ongukuphela kwakhe ophilayo kanye nezinye izinto eziphilayo, kodwa futhi abalethe usizo olungenakuqhathaniswa. Ngokwesibonelo, lezi zidalwa ezincane bahlala nezilimo eziyizigaxa okusanhlamvu. Ziba nitrogen, okuyinto nomanyolo for izitshalo. Kubantu nasezilwaneni nazo eziphila manje. Bavumela izinga esiphezulu ukudla kusetshenzwe okulungiselelwe nezihlukene ukubaluleka olukhulu amavithamini impilo.

izakhiwo awusizo-bacterium

Kwenzeka isimanga, lesi isisindo ingqikithi nezilwanyana ezincane ezihlala emzimbeni wethu imayelana ezimbili amakhilogremu. nama-bacterium awusizo lapho abahlala umzimba isidalwa esiphilayo, esibizwa microbiota. Indikimba ngayinye abangaphezu kwesigidi. Microbiota unesibopho impilo enhle. nama-bacterium awusizo ukuvikela umzimba ekulweni namagciwane.

Le ndawo eyinhloko ukusatshalaliswa microbiota - kungcono emathunjini. nama-bacterium awusizo simondzawo esidi lapho ningathwali eziphilayo adala izifo.

Ukuvikelwa kwemvelo

I izakhiwo amabhaktheriya ukuthi zitholakala umgudu womuntu futhi phezu kobuso isikhumba sakhe, ukuvikela endaweni yazo. I Amagciwane ayingozi kakhulu ukuthi ukuhlasela emikhulu ebusweni bomhlaba kuyimiphumela streptococcus, Staphylococcus futhi micrococcus.

Phakathi namakhulu eminyaka ambalwa adlule, ukuvikelwa kwemvelo kwesikhumba womuntu uye washintsha eziningi eziphawulekayo. Lokhu kungenxa yokuthi umphakathi uye wathuthela ebangelwa ukuba nobuhlobo obuseduze nemvelo contact njalo amakhemikhali. Ososayensi baye bafakazela ukuthi isethi microbiota, okuyinto phezu kwesikhumba namuhla ngokuphongoza ukuthi obabukhona ngaphambili.

Ukubuyiselwa microworld

Kuyaziwa ukuthi microbiota i umzimba olusha ngokushesha. amagciwane Amandla incike isabelo esiphathiswa. I esiyingozi kakhulu nezilwanyana ezincane ukuze ukudla aqukethe imithi elwa namagciwane, nezivimbelakuvunda kanye colorants yokufakelwa. Lezi izinto ukubhubhisa microcosm angokwemvelo. Unalokho ngokuzayo kungabanga ezihlukahlukene zempilo.

Kubalulekile ngempela ukuqaphela ukuthi microcosm kudinga nokuqikelela. Sincoma kakhulu ukuthi ngezikhathi ukubuyisela microbiota ukuvimbela eziningi izifo. Lokhu kudinga ukusetshenziswa probiotics Yiqiniso. Ukuze alondoloze microcosm ayo kumele zidle amaveji ngaphezulu, ukwenza izinsuku ukudla futhi kwasemini iphalishi zemvelo.

Abaningi banesithakazelo umbuzo kanjani ukondla amagciwane atholakala emzimbeni wethu. Sithole ukuthi kuzuzisa amagciwane kudle iyafana inkampani yakhe. Kungenxa yalesi sizathu, ukuze silondoloze uhlelo sihlale siphilile kwasekuqaleni kubalulekile ukuba aphinde acabange ekudleni kwakho.

Enzyme ngokuthuthukisa isimo jikelele

Mhlawumbe ukuba ngamunye wethu uyajabula ujwayelene isimo, lapho emva kokudla kubonakale sibi impilo jikelele. Ngo ezifana icala kuyoba enzyme kubalulekile virus. Kuphi ukuze uwathole futhi indlela abenza ngayo emzimbeni womuntu?

Abaningi bathi ngemva ukweqisa iholide abazizwa ezimbi izinsuku ezimbalwa. Bayakhononda of goiter, ubuthakathaka kanye nokuntuleka ukudla. Zonke lezi zimpawu ibonisa ukuthi ama-bacterium ayingozi ozama push enempilo. Ukuze sibhekane inqubo enjalo futhi ukubuyisela impilo enhle, kubalulekile ukukufaka ekudleni ukudla yakhiwa enzyme virus. Lezi zihlanganisa ushizi, noshizi kanzima, kefir, yogurt, ubisi oludakisayo nezitini kanye nezinye ukudla yobisi. Ochwepheshe batusa nokuba ukuthatha imikhiqizo aqukethe probiotics. Ngaphambi kokuqala ukwelashwa, it is kakhulu Kunconywa ukuba bonana nodokotela wakho kuqala.

Ukutholakala kwemilingo. Ama-bacterium adla plastic

Sakhiwo umsebenzi ebalulekile yamagciwane iyathakazelisa izazi zezinto eziphilayo ezivela emhlabeni wonke. Bakholelwa ukuthi izilokazane ezincane akuzona bakudala ngakho njengoba kuzwakala. Lokhu kuqinisekisa ukutholakala eyenziwe iqembu biochemists Chinese microbiologists. Eminyakeni emibili edlule, bathola amagciwane udle plastic. Ngokusho ososayensi, lokhu uyosindisa iplanethi kusuka Inhlekelele yezindawo zemvelo.

Lokhu kwatholakala ngengozi. Inhloko leli qembu lathi ukuthi indlu yakhe lihlale lingcolile lula. Ngelinye ilanga ngaphawula ukuthi inani elikhulu elincane izibungu ekhona upulasitiki izinsalela okusanhlamvu, okuyinto ashwabadele emaphaketheni zalutho. Leli cala utshelwa abacwaningi bakholelwa ukuthi esingayenza engasiza ekusindiseni iplanethi ukungcola global.

Ngachitha eziningi ucwaningo, umholi weqembu wathola ukuthi hhayi izibungu kuphela udle plastic kanye polyethylene, kodwa futhi ingagayeka. Kwatholakala ukuthi lokhu kungenxa yokuthi esiswini amacimbi eziningi amagciwane. Kuyinto ba futhi inhlabamkhosi ezinobuthi. Iqembu lososayensi ubeke test izibungu phezu polyethylene. Ngokumangalisayo, kodwa kamuva ngenyanga base kuhlolwa iphakethe ngesibonakhulu. Amandla ivumela amagciwane hhayi ukuthumela plastic kabusha, ulichithe ngokushesha ngangokunokwenzeka.

amagciwane ayingozi olwenzeka endaweni

Kukhona zombili nama-bacterium awusizo kanye yisinanakazana. Lesi sakamuva singabangela ukuphuphuma eziningi zempilo. Ukuze wengeze ukuvikela umzimba wakho kusuka amagciwane ayingozi, kubalulekile ukwazi kahle lapho behlala khona.

• Into dirtiest endlini, okuyinto othanda ukuba kwamagciwane ayingozi - kuyinto isiponji for izitsha. Kakade emva kwesonto usebenzisa kulo unomuzwa wokuphuthuma idinga ukushintshwa. Ezimanzisa sponge, okwakukhona izinhlayiyana zokudla - indawo evumayo sokuthuthukiswa nezilwanyana ezincane yisinanakazana.
• Esinye isihloko okungukuthi kangaka uyakuthanda izidalwa ezincane - isixubho. esikhundleni ezingavamile ngcono ezifana kungaholela ezihlukahlukene izifo ezithathelwanayo ezifana SARS.
• Bambalwa abantu abacabanga, kodwa TV akude - kuba isihloko lapho uhlala lenqwaba kwamagciwane ayingozi ukuphila komuntu. Ukuze uzivikele ethonyeni layo, kubalulekile okungenani kanye ngesonto ukuze asingathe lesi isihloko magciwane. Uma esikhathini othile emndenini ithwala isifo esithathelwanayo, lokhu kufanele kwenziwe nsuku zonke.

Ukuze uzivikele eziningi amagciwane ayingozi, kubalulekile ukuthi ugeza izandla kaningi ngangokunokwenzeka. Ukuze avelele, njalo usebenzise isibulala-magciwane.

kabusha nezilwanyana ezincane

Kulabo abafisa ukufunda okwengeziwe mayelana izilokazane ezincane ezilula, kubalulekile hhayi kuphela ukuthi leli gciwane zidla, kodwa futhi indlela ukukhiqiza kabusha. Lolu lwazi iyathakazelisa eziningi Wabasaqalayo microbiologists. Iningi iseli webhaktheriya replicates sokuhlukanisa zibe izingxenye ezimbili. Uma lesi silwanyana ine kobujamo obusaqanda, kungaba kuphela okufanele lihlukaniselwe bona yonkana. Kukhona futhi izinhlobo ukukhiqiza kabusha by luthela. Inqubo ngokobulili ivelakancane futhi ngokuvamile kuphela E. coli.

Inqubo yokuzalana ku-bacterium senzeka ngokushesha ngokwanele. Noma kunjalo, lo division kungathatha indawo kuphela ngaphansi kwezimo ezithile. Ngaphansi kwezimo ezingezinhle, ezinye zenyathi bacterium angase yakha ezinhlamvu. Ngokumangalisayo, kuseli eyodwa, nizitholele abantu kunezigidigidi ezimbalwa zezingosi. Iningi inzalo abasha bafa ngenxa yokuchayeka kwezimo zendawo ezimbi.

efingqa

Ama-bacterium - a eziphilayo elula kangaka ezisizungezile yonke indawo. Abakwazi nemithelela zombili zibe phozithivu futhi omubi kwezemvelo kanye nempilo yabantu. microbiologists Abaningi bakholelwa ukuthi leli gciwane akuzona lula njengoba kubonakala. Namuhla nezilwanyana ezincane eyaziwa ezingasiza wakwazi ukubhekana kangcono nale enhlekeleleni yezinto eziphilayo emhlabeni. Kulesi sihloko ungathola ningakhathaleli nje kuphela indlela amagciwane ukondla, kodwa futhi ukwazi indlela ukuzalela aphefumule.
