Streptococcus viridans: characterization o ka pathogen a me ka maʻiʻaʻai

Microorganisms mea a pau a puni mākou, a noho i loko o mākou kino, e like me ka integral hapa o ia a me ke ao ma nui. Eia naʻe,ʻaʻole i pilikia loa i ko makou ola kino a pau o ia mau mea, ma ka mea ku ole, ka poe koʻohune mea e i ka maʻamau flora o na kanaka nā loko, pale aku malihini microbes, a pale aku i ka hanana o nā mea palahēhē. Eia hou, nui ka hehee ai o ka hoomalu ana o ka'ōnaehana paleʻea'ōnaehana, akā, i ka wa a ka mea, ua hoʻonāwaliwali i hiki conditionally pathogenic flora hiki i maʻi. Kekahi o lākou brightest elele mea streptococcus viridans, a e e kūkākūkā.

kumu 'ike

I ole ia haawiia ia me "ka puʻu zelenyaschy", keia mea he maʻamau noho ana o na kanaka ku una lua, kahi e ua IIeEeAIEUIeXAIIUE i na niho a me ka nui aʻe ana, a me ka pinepine lilo i kumu o ke kahua niho caries. He mea no ka mea, i loko o ka 'ole o ka streptococcus viridans mai he kūikawāʻilikai kumuʻiʻo i ka mea hiki ke paa i ka tuha, a pela i pili i ka niho. A sucrase komo me ka ai e pio ia i loko o lacticʻakika, corroding enamel. Kona hana hoihoi inoa, ua loaa no ka wā bacteriological Hagara mau koʻohune kuahene a puni o ko lakou mau panalaau ia zelenyaschy oo? O hemolysis lulu ia ma luna o ka momona lepo o ke koko. Eia naʻe, loaʻa nō nā pūʻulu o keia hemolytic streptococci (loa hemolyzed 'ia) a me ka' ole-hemolytic (haemolytic i nā'ūhū). I e like me ka mea mua streptococcus pūʻulu viridans i pilikia no kanaka kino a me ka mea, ua ikaika nui ae emi virulent. Naʻe, a me ka mea hoʻonāwaliwali maoli nō o ka e hoʻonele, ka mea, e 'Imi hoonui loa, a i ka pathogenic hookoia, e kauoha ana opportunistic nā mea palahēhē, aʻaʻole e mau ana ka maʻalahi papa.

microbiology

Ano, e ka nana i hou au mamuli ka mea streptococcus viridans. Inā mākou e kamailio e pili ana i kēia mau koʻohune mai ka microbiologicalʻoi o ke hoomaopopo, ka mea i spherical paha ovoid gram-maikaʻi cocci, mai hana spores. Ka mea, no a hiki i ka pae ana o facultative anaerobes a me nā Streptococcaceaeʻohana. E loaʻa mai i ka mea nana e like streptococcus viridans, i ia mea, e nana ana ma ka malamalama microscope. Pela no oe e ike i ka hapanui o ia e hoonohonoho i ka hui a hele i loko o nā kaula hao, akā, koe wahi. Ka mea, e he pilikia i nā'ōnaehana paleʻea'ōnaehana moe i loko o ka mea ana ka mea e hiki ke hana i kekahi mea hōʻikeʻikeʻuʻuku ia i malama mai phagocytosis ia ma ka hana kūikawā koko keena, a hiki wale ke hoohuliia i loko o ka L-kinona, pela mutating, a no laila, e hiki i ka lōʻihi manawa pee mai na eiiiiiaiou o ko mākou pale nenoaiu.

Hua a me ka virulence

Nutrient olelo o kēia mau koʻohune, e like staphylococci, i loa eiiieaena. Ko lakou ulu ana pono wale i loko o kēlā mau hana kūpono ma i ka makaukau o ka a pau i ke koko a me ka lāʻau lapaʻau, e like me ka mea pono Pono carbohydrates i ka mana i hoʻohana. I mea no ke aha la ka hapanui o bacteriological seeding viridans streptococci hoʻohana koko Hagara. Ma ka mea mawaho i hoʻolilo 'ia, ka mea e loa i ka pilina paʻa, no ka mea, no ka mea hoike, i ka maloo liluwelo pono hana (koko, pus, sputum), ka mea hiki ke kōkua ma muli o kā lākou viability no kekahi mau mahina. Pasteurization, disinfection, ka mea make, akā,ʻaʻole koke. Penei, ka wā enaena i ka wela o ka 60 kekelē Kelekia ma kā lākou make wale ia lŘlŘ ma ka hapalua o ka hora, a me ka palapala noi Des. kumuwaiwai - i loko o 15 minuke.

epidemiology

Ka mea i waena o ka mau microflora o ke kino o ke kanaka, a me na mea he nui koʻohune, komo a me ka streptococcus viridans - kūmau. Naʻe, pili keia wale i ka kekahi helu o kona ke kanana nei, a ua hoʻolakoʻia aʻe ka mea, e hiki mai mailoko o kanaka, oa nā moku halihali mokulele o ka streptococci a ua iho mailoko o kekahi o ka nuiʻano o ka maʻiʻaʻai (loa puu, heʻulaʻula kuni, pneumonia, etc.). Ka noho pilikia loa nā mea maʻi me ka hoaka o ka naehana'āpana nā mea palahēhē, no ka mea, hoʻokuʻu akula nui aku streptococci i loko o ke kaiapuni. Nolaila, i ke kumu nui ala hele o ka maʻiʻaʻai - airborne,ʻo ia hoʻi, ma ka olelo ana, kiheʻana, me ka puʻu, honi, a pela aku.; ma kekahi hihia i hiki'aiaola (dietary) a me ka hui '(ʻino lima). Ua ua ike i na mea he nui o ka pae A streptococci ke noke kōkua ma muli o kā lākou virulence waiwai ma ka hui 'ana me nā huahana, i mea ai no lakou, ma ka mea, he maikaʻi' ia. O nā hua paha, ka waiu, o Hama, a me ka pūpū.

complications

Ke loa na olelo hooweliweli e maʻi, kena ae la ia e viridans a me ka 'ole-hemolytic streptococci, Ua infective endocarditis. Ka mea i hāʻule i loko o ka kūloko, a laila, i ka systemic holo ka wā poino o ku una mucosa (nui aʻe ana, elelo) toothbrush ole floss stomatitis streptococcus viridans. Hiki i ka naau, ka mea hiki e pili ana i ka nohona kiwikā a panalāʻau mua ia. Penei e hoʻomōhala ana i ka maʻi. Ua hoʻomaka, e like me ka rula, he pono ole symptoms: nawaliwali, malaise, kuni. O ke kumu ho kuhikuhi ana i ka mea e pinepine ia ke kumu lōpū paha slabovirulentnye ke kanana nei.

Ke Kalinika a me nā haumāna

Inā i ke kumu o infective endocarditis mea i aloha koʻohune, ka maʻi hoʻomaka ke hākilo loa, a hele pū febrile wela, i ke kanaha degere. Ma keia hihia, aia nō ia laua Muscle a me ka olelo eha, a me ka auscultation lohe naau ohumu. Ka pilikia o kēia maʻi o ka make ana o ka endocardium, a laila i ke ano o ka deformation kiwikā mea koʻohune mea kanu a ma luna o ia mau mea. Me kā lākou poe e hoʻomōhala ana i microbial embolism na moku, e alakai i ka naʻau ho'āhewa wale a me ka hahau ana. Eia hou, i ka aneurysm ke hana nui arteries, lolo abscess, meningitis, encephalopathy a me ka naʻau 'ole.
