Kev faib tawm lub cev: Streptococcus agalacti
Yog li ntawd, Gram positive bacteria txhais li cas?
Kho mob Txhais ntawm Gram - zoo Gram - zoo : Gram - cov kab mob zoo khaws cov xim ntawm crystal violet stain nyob rau hauv lub Gram stain. Qhov no yog yam ntxwv ntawm kab mob uas muaj cov phab ntsa ntawm tes tsim los ntawm cov txheej tuab ntawm cov khoom tshwj xeeb (hu ua peptidologlycan).
Tom qab ntawd, lo lus nug yog, kev kho mob rau gram zoo cocci yog dab tsi? Kev kho mob : Enterococci yog inherently resistant rau ntau chav kawm ntawm tshuaj tua kab mob uas nquag tawm tsam lwm tus gram positive cocci , suav nrog cephalosporins, macrolides, thiab clindamycin.
Hais txog qhov no, kab mob dab tsi tshwm sim los ntawm Gram positive cocci?
Streptococcus pyogenes yog ib pawg gram-zoo A cocci uas tuaj yeem ua rau pyogenic kab mob (pharyngitis, cellulitis, impetigo, erysipelas), toxigenic kab mob (scarlet fever, necrotizing fasciitis), thiab immunologic kab mob (glomerulonephritis thiab rheumatic fever). ASO titer ntes S. pyogenes kab mob.
Cov kab mob Gram zoo puas tsim kev puas tsuaj?
Gram - zoo Cov kab mob feem ntau tsis tshua muaj hnyav vim tias tib neeg lub cev tsis muaj peptidoglycan, thiab qhov tseeb tib neeg lub cev tsim cov enzyme hu ua lysozyme uas tawm tsam qhov qhib peptidoglycan txheej. Gram - cov kab mob zoo.

Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Gram + ve thiab Gram yog dab tsi?
Cov kab mob Gram zoo muaj txheej tuab peptidoglycan thiab tsis muaj cov lipid txheej sab nraud thaum cov kab mob Gram tsis zoo muaj txheej nyias peptidoglycan thiab muaj txheej txheej lipid
Puas yog Gram positive bacteria kis tau?
Cov kab mob gram-zoo yuav yog cocci lossis bacilli. Qee cov kab mob Gram-zoo ua rau muaj kab mob. Lwm tus ib txwm nyob ntawm ib qho chaw hauv lub cev, xws li daim tawv nqaij. Cov kab mob no, hu ua nyob hauv flora, feem ntau tsis ua rau mob
