Pathogenicity a me virulence o microorganisms. Virulence - ia ...

Ke kanaka kino ka hale a hiki i kahi o 100 trillionov koʻohune. Epekema no i keia la i wale e hoakakaʻike nōʻo ia i kēia mau kaiaulu luna 'pāʻani aku me ke kanaka. Ka mea, he aha ka mea i ke kaʻina hana o ka digestion, ka'ōnaehana paleʻea nenoaia a paha a hiki i ka noʻonoʻo maikaʻiʻana. Naʻe, i nā mea a pau koʻohune ke coexist me ke kanaka kino me ka maluhia a me ka lokahi. Ua kapa pathogenic microorganism e hiki i maʻi i loko o mea kanu, holoholona a me nā mea kolo. Microbes ka hoike lākou pathogenicity hoʻohana 'virulence. No laila, he aha ka mea i ka virulence?

I ka manaʻo o ka virulence

Virulence - mea he kau e wehewehe i ka degere o ka pathogenicity o ka microbe. No laila, na determinants o virulence o ka pathogen o kekahi o kona aaiaoe, biochemical paha mall hiʻona e ae kumu maʻi.

Ka pilina ma waena o ka poʻe kaua, a me ka pathogen i mau hōʻeuʻeu, no ka mea, kela mea keia mea hiki ke hoʻololi i ka ha awina a me ka mana o ka mea 'ē aʻe. I ka hope o ka pilina ma hilinaʻi nui ma luna o ka virulence o ka pathogen, a me ka hoahanau degere o ka ia'ku paha susceptibility o ke kaua. kūlana nui An ua pâʻani 'laulā o aiiay maomeka o ka meaola.

Virulence kumumea 'ana e pili ana i ka waiwai e ae nā palapala microorganisms loaʻa i loko o' ole ma o ka kino o ka puali, a me ka mea maʻi. O nā mea koʻohune toxins e hoʻonui ai i ka pathogenicity.

nui manaÿo

Invasiveness - kēiaʻikeʻia i loko o ka'aʻaʻa. Ua nā maomeka no e hiki colonization a? Iecaianoaaiiie o extracellular waiwai e hoʻonui ai i ka manawa kūpono o ke kaua, a circumvent a lanakila kekahi aiiay maomeka.

Toksogennost - ka hiki e excrete toxins. Koʻohune hiki paka nāʻano o nā toxins: endotoxins a me exotoxins. Exotoxins hookuu mai mea koʻohune keena , a paipai i ka ulu ana o koʻohune. Endotoxins i aeea waiwai.

Mea koʻohune toxins, nā wailana a me aeea-pili, hiki e kaʻi aku ma ke koko a me ka lymph'aʻaʻa, a i cytotoxic 'ole ma ka wahi keʻena mai ka loiloi muaʻoi o ke anal. Kekahi mea koʻohune toxins i kekahi hana panalāʻau e komo i loko o ke kaua.

Pathogenicity a me virulence o microorganisms

Pathogenicity - i ka hiki ana o ka meaola i ka i maʻi. Kēia hiki He He aaiaoe ke keʻena o ka pathogen, a ia i hoeha mai kaʻaoʻao puali. No ka opportunistic pathogens, ua hiki i ka mea maʻi mea ole innate. Pathogens ke hoike i ka laulā huahelu o ka virulence.

Virulence - he manaʻo i ua inextricably ua hoʻopili i ka manaʻo o ka pathogenicity. Ke degere o ka virulence o ka pathogen ua ana correlated me ka hiki, e replicate i loko o ka poʻe koa, a ke hilinai aku ma luna o kekahi mau aʻe. virulence kumumea he hoʻonui i ka pathogenicity, oa kōkua i ka i maʻi.

Pathogens

Ua nui ua pinepine ae la oia e holo ana hoʻolohe i nā hoʻolaha likeʻole o ka huahana nā hoʻolaha i koi e pepehi 99% o germs. Pathogen - he kau hoʻohana 'ia no ka hōʻike liʻiliʻi meaola (koʻohune a me nā mea hoʻomaʻi), e kauoha ana na maʻi. Ma ka liluwelo terminology, ka mea, uaʻikeʻia kekahi e like me ka causative hope. He nui na ano o ka pathogens mea i maʻi likeʻole HEN, mai ka pono anu a me ka pau maʻi 'aʻai.

Pathogenic microorganisms lakou aloha ia i kekahi kanaka i loko o na aoao, ke kaumaha ma muli o ko lākou virulence. Virulence - he kau hoʻohana 'ia e wehewehe i ka laulā o kekahi pathogen. Ka oi virulent pathogen ua, ka hou ia, e i ka hopena maikaʻi ma luna o kanaka ola.

Makaʻu o virulence

Virulence kumumea nā hiʻona pathogens i hooholo i paʻa pathogen virulence. Ka hou, i ka mea i oi aku ka likelihood ia ia, e lilo ia i ke kumu o ka maʻi. Mau kumumea haawi i ka lanakila i ka Hana ana me na kanaka'ōnaehana paleʻea'ōnaehana, a me ka nui, o ka oi luku mea hiki ia.

Aia i kekahi mauʻano o ka virulence kumumea i i e noho paha ma kahi'ē ma ka kekahi pathogen: nā kumumea o colonization, enterotoxins a me hemolysin. Virulence - mea he laupaʻi kāna moʻolelo ka, no ko ka i ka degere o ka maʻi, kena ae la ia e ka microorganism. Kēia hiʻona, i expresses AaOIeIOUIeXAOAaIN ma waena o ka pathogen, a me ka lawe. Virulence ua ana correlated me ka hiki ana o ka pathogen e proliferate. Ua hiki no hoi hilinaʻi ma o ka lawe a? Aneie aʻe.

A mea koʻohune pathogen ua ana hoakaka me kekahi bacterium i ka hiki ana o na la maʻi. Kona hana i ka i maʻi ua kapaia pathogens. Ke virulence o ka microorganism mea pololei e kaukaʻi ma ke ano o ka maʻiʻaʻai a me ka mea he anakahi o ka oolea o ka maʻi i ia kumu.
