Streptococcus viridans: mapangidwe a tizilomboto ndi matenda

Tizilombo ali ponseponse ndipo akukhala mu thupi lathu, monga mbali yofunika ya izo ndi dziko pa lalikulu. Komabe, si onse amene ali oopsa thanzi lathu, pa M'malomwake, anthu mabakiteriya amene amapanga zomera yachibadwa ziwalo zosiyanasiyana, kukana tizilomboto mlendo ndi kuteteza zosayembekezereka matenda. Komanso, chinthu chofunika chitetezo ndi chitetezo cha m'thupi, koma pamene zofooketsa ngakhale salembedwa zomera tizilombo zingachititse matenda. Mmodzi wa owayimilira yowala ndi streptococcus viridans, tikambirana.

mfundo zofunika

Apo ayi amatchedwa "strep zelenyaschy", ino ndi wokhala yachibadwa ya m'kamwa zibowo zam'mano munthu, kumene iwo isanafalikire kwa mano ndi m'kamwa, ndipo kawirikawiri chifukwa cha caries mano. Ichi ndi chifukwa kapangidwe ka viridans streptococcus ali wapadera padziko mapuloteni amatha kumanga ndi malovu chotero Ufumuyo dzino. A sucrase chikuonetseratu ndi chakudya otembenuka mu asidi lactic, corroding enamel. Dzinali chidwi anapatsidwa chifukwa pamene bacteriological kufesa pa nthaka yachonde magazi ndi Hagara mabakiteriya izi kupanga padziko njuchi awo zelenyaschy zone ya hemolysis. Komabe, pali magulu ena a ichi streptococci hemolytic (kwathunthu hemolyzed chilengedwe) ndipo sanali hemolytic (haemolytic ndi michere). Poyerekeza ndi woyamba streptococcus gulu viridans si owopsa kwa thupi la munthu ali kuli chosakaza. Komabe, ndi chifooke chitetezo chokwanira, iwo zikukangalika kuchulukitsa zinthu ndiponso tizilombo, kuchititsa matenda osadziwika, ndipo si nthawi zonse kosavuta.

tizilombo tosaoneka ndi maso

Tsopano tiyeni tiyang'ane mwatsatanetsatane zimene streptococcus viridans. Ngati ife kulankhula za mabakiteriya izi kwa mfundo microbiological maganizo, iwo ali ozungulira kapena ovoid galamu HIV cocci, musati kupanga spores. Adzaupereka kwa gulu la anaerobes facultative ndipo zikuphatikiza Streptococcaceae banja. Kuti tipeze chimene chimaoneka viridans streptococcus, chimene icho chiri, tangoyang'anani mu kuwala maso. Kotero inu mukhoza kuona kuti ambiri a iwo anakonza awiriawiri kapena kupita ku unyolo, koma kukhala n'kupuma. Iwo ali pangozi kwa chitetezo cha m'thupi kwagona kuti akhoza kupanga kapisozi kuwateteza ku phagocytosis ndi maselo apadera magazi, ndipo m'posavuta mu L-mawonekedwe, motero mutating, nafenso nthawi yaitali asilikali zigawo za dongosolo lathu chitetezo.

Fesani ndi virulence

zofunika michere mabakiteriya awa, mosiyana staphylococci, ndi zovuta kwambiri. Iwo amakula bwino kokha anthu mapangidwe imene yokonza magazi athunthu kapena seramu, ngati iwo kwenikweni ayenera chakudya mphamvu ankagwiritsa ntchito. N'chifukwa chake ambiri seeding bacteriological viridans streptococci ntchito magazi Hagara. Mu malo kunja, ali wolimba kwambiri, chifukwa Mwachitsanzo, pa zouma zipangizo kwachilengedwenso (magazi, mafinya sputum), akhoza kukhala viability awo kwa miyezi ingapo. Pasteurization, disinfection, kufa, koma osati panopa. Choncho, pamene usavutike kutentha madigiri 60 Celsius imfa yawo kumachitika kokha pa theka la ola, ndi ntchito des. chuma - mphindi 15.

EPIDEMIOLOGY

Mfundo yakuti mwa microflora mwachizolowezi wa thupi, pamodzi ndi mabakiteriya ambiri, alowa ndiponso streptococcus viridans - ponseponse. Komabe, izi amangonena za nambala inayake tizilombo ta ake, ndi kudzadza chitha anthu kachilombo, onyamula mwachitsanzo wa streptococci kapena kale kachilombo wina wa mitundu yambiri ya matenda (zilonda zapakhosi, fever, chibayo, etc.). Odwala owopsa ndi matenda chapamwamba kupuma thirakiti, chifukwa iwo zimatulutsa streptococci zambiri mu chilengedwe. Motero, njira yaikulu ya matenda - airborne, ndiko, ndi kulankhula, sneezing, kutsokomola, nampsopsonetsa, etc. zina n'zothekanso zakudya (zakudya) ndi kukhudzana (zauve manja). Amadziwika kuti ambiri a gulu streptococci akhoza mosalekeza kukhala virulence katundu wawo pokhudzana ndi katundu, amene iwo, kunena, malo abwino. Zikuphatikizapo mazira, mkaka, nyama ndi nkhono.

zosokonezeka

The matenda ambiri oopsa chifukwa cha viridans ndipo sanali hemolytic streptococci, ndi infective endocarditis. Mfundo yakuti kugwa mu malo komanso kufalitsa zokhudza zonse pamene kuvulala kwa mucosa m'kamwa (m'kamwa, lilime) wamsuwachi kapena floss stomatitis streptococcus viridans. Ufike pamtima, iwo akhoza Ufumuyo mavavu ndi yolowera iwo. Choncho akufotokozera matenda. Umayamba, monga ulamuliro, ndi zizindikiro zosonyeza kuti: kufooka, malaise, malungo. Ichi ndi chifukwa makamaka chakuti nthawi zambiri amayambitsa zolimbitsa kapena slabovirulentnye tizilombo.

Clinic zakambidwa

Ngati chifukwa cha endocarditis infective amapatsa bakiteriya, nthendayo imayamba bwinobwino ndi limodzi febrile kutentha, mpaka madigiri makumi anai. Pankhaniyi pali kufanana minofu molumikizana mafupa, ndi auscultation anamva mtima kudandaula. Kuopsa kwa matenda ndi chiwonongeko cha endocardium ndi, i.e. maonekedwe a mapindikidwe vavu bakiteriya vegetations pa iwo. Ndi detachment awo akufotokozera tating'onoting'ono ziwiya embolism, zikubweretsa matenda a mtima ndi sitiroko. Komanso, aneurysm akhoza kupanga mitsempha yaikulu, ubongo abscess, kakhosi, encephalopathy ndi matenda a mtima.
