Qhov sib txawv tseem ceeb ntawm Streptomyces thiab Streptococcus yog tias Streptomyces yog ib hom kab mob gram-positive filamentous, thaum Streptococcus yog ib hom kab mob gram-positive coccus lossis cov kab mob spherical.
kab mob kab mob yog cov kab mob uas tuaj yeem ua rau muaj kab mob. Feem ntau hom kab mob no tsis muaj teeb meem thiab muaj txiaj ntsig. Txawm li cas los xij, qee cov kab mob tuaj yeem ua rau kis kab mob. Cov kab mob pathogenic uas tuaj yeem ua rau tib neeg kis tau yog kwv yees tsawg dua. Cov kab mob pathogenic yog tshwj xeeb yoog thiab muaj txiaj ntsig cov txheej txheem uas tuaj yeem kov yeej lub cev tsis muaj zog thiab yoog raws kev tiv thaiv kab mob. Cov kab mob no, yog li ntawd, tuaj yeem nkag mus rau ntau qhov chaw ntawm lub cev, suav nrog cov ntshav, lymphatic system, tawv nqaij, hnoos qeev, ua pa, plab hnyuv, thiab lub hlwb. Streptomyces thiab Streptococcus yog ob hom kab mob uas ua rau muaj kab mob hauv tib neeg.
Streptomyces yog dab tsi ?
Streptomyces yog ib hom kab mob gram-positive filamentous. Lawv yog cov kab mob aerobic. Ntau tshaj 500 hom kab mob Streptomyces twb tau txheeb xyuas lawm. Streptomyces hom tsim tau zoo-tsim vegetative hyphae 05-2 µm nyob rau hauv txoj kab uas hla nrog ceg. Lawv tsim ib tug complex substrate mycelium uas pab nyob rau hauv scavenging organic tebchaw. Txawm hais tias mycelia thiab aerial hyphae uas tshwm sim los ntawm cov kab mob no yog motile, kev txav mus los tau ua tiav los ntawm kev tawg ntawm cov spores. Qhov chaw ntawm cov spores yog plaub hau, du, rugose, spiny, los yog warty.
Daim duab 01: Streptomyces
Lub genome ntawm Streptomyces muaj G-C cov ntsiab lus siab. Qhov ua tiav genome ntawm tus kab mob Streptomyces coelicolor A3(2) tau luam tawm xyoo 2002. Cov chromosome ntawm cov kab mob no yog 8, 667507bp ntev nrog GC cov ntsiab lus ntawm 72.1%. Lub genome ntawm tus kab mob no tau kwv yees tias muaj 7, 825 protein-encoding genes. Cov hom ntawm no genus yog feem ntau pom nyob rau hauv cov av thiab decaying zaub. Tsis tas li ntawd, lawv tau sau tseg rau lawv cov ntxhiab tsw hauv ntiaj teb, uas yog los ntawm kev tsim cov tshuaj metabolite hu ua geosmin. Tsis tas li ntawd, cov kab mob no tsim ntau tshaj ob feem peb ntawm cov tshuaj tua kab mob tseem ceeb uas suav nrog neomycin, cypemycin, grisemycin, bottromycins, thiab chloramphenicol. Streptomyces hom yog cov kab mob tsis tshua muaj. Lawv ua rau muaj kab mob xws li mycetoma thiab actinomycosis (S. somaliensis thiab S. sudanensis) hauv tib neeg. Qee hom nyob rau hauv cov genus no yog cov nroj tsuag kab mob xws li S. turgidiscabies (kab mob kab mob hauv cov qos yaj ywm) thiab S. ipomoeae (mob rot kab mob hauv qos yaj ywm qab zib).
Streptococcus yog dab tsi?
Streptococcus yog ib hom kab mob gram-zoo cocci lossis kab mob kheej kheej. Kev faib tawm ntawm tes hauv cov kab mob Streptococcus tshwm sim raws ib qho axis. Raws li lawv loj hlob, lawv nyiam tsim cov khub los yog cov saw hlau uas yuav tshwm sim khoov lossis twisted. Cov kab mob no txawv ntawm Staphylococci, uas sib faib raws ntau lub axis, yog li tsim cov kab mob tsis sib xws. Feem ntau cov kab mob Streptococcus yog catalase-tsis zoo thiab oxidative tsis zoo. Streptococcus hom yog facultative anaerobes.
Daim duab 02: Streptococcus
Ntau tshaj 50 hom tau lees paub hauv cov genus tam sim no. Ntxiv mus, cov genus no tau pom tias yog ib feem ntawm salivary microbiome. Feem ntau streptococcus genomes muaj li ntawm 1.8 txog 2.3 Mb qhov loj. Cov genomes no encode 1700 txog 2300 proteins. Tsis tas li ntawd, cov kab mob Streptococcus ua rau muaj kab mob sib txawv xws li S. pyogenes (pharyngitis, cellulitis, erysipelas), S. agalactiae (neonatal meningitis thiab sepsis), S. gallolyticus (endocarditis, urinary tract infection), S. anginosus (mob ua pa), S.. mutans (dental nqa), S. pneumonia (pneumonia).
Dab tsi yog qhov zoo sib xws ntawm Streptomyces thiab Streptococcus ?
- Streptomyces thiab Streptococcus yog ob hom kab mob pathogenic.
- Cov kab mob hauv ob hom kab mob yog gram-positive.
- Lawv ua rau mob rau tib neeg.
- Cov kab mob hauv ob hom kab mob muaj cov kab mob phem.
- Cov kab mob tshwm sim los ntawm cov kab mob ntawm cov genera no tuaj yeem tswj tau los ntawm kev xaiv tshuaj tua kab mob.
Qhov txawv ntawm Streptomyces thiab Streptococcus yog dab tsi?
Streptomyces yog ib hom kab mob gram-positive filamentous, thaum Streptococcus yog ib hom kab mob gram-positive coccus lossis cov kab mob spherical. Yog li, qhov no yog qhov txawv ntawm Streptomyces thiab Streptococcus. Ntxiv mus, ntau tshaj 500 hom tau lees paub hauv Streptomyces genus. Ntawm qhov tod tes, ntau dua 50 hom tau lees paub hauv Streptococcus genus.
Cov ntawv qhia hauv qab no nthuav tawm qhov sib txawv ntawm Streptomyces thiab Streptococcus hauv daim ntawv qhia rau ib sab ntawm kev sib piv.
Summary – Streptomyces vs Streptococcus
Streptomyces thiab Streptococcus yog ob hom kab mob uas ua rau tib neeg kis tau. Streptomyces yog ib hom kab mob gram-positive filamentous, thaum Streptococcus yog ib hom kab mob gram-positive coccus lossis cov kab mob spherical. Yog li, qhov no qhia txog qhov sib txawv ntawm Streptococcus thiab Streptococcus.
