Microbial tshuaj lom yog toxins tsim los ntawm cov kab mob me me, suav nrog kab mob thiab fungi. Microbial tshuaj lom txhawb kev kis kab mob thiab kab mob los ntawm kev puas tsuaj ncaj qha cov ntaub so ntswg thiab los ntawm kev xiam oob khab. Ib txhia cov kab mob co toxins , xws li Botulinum neurotoxins, yog qhov muaj zog tshaj plaws toxins paub.
Tsuas yog li ntawd, puas yog cov kab mob co toxins proteins?
Ntau kab mob toxins yog cov protein , encoded los ntawm kab mob chromosomal noob, plasmids los yog phages. Lysogenic phages tsim ib feem ntawm chromosome. Cov tshuaj lom feem ntau yog kev tso tawm los ntawm cov kab mob los ntawm lysis, tab sis qee qhov raug tso nrog txheej sab nrauv cov protein nyob rau hauv sab nrauv vesicles.
Qhov thib ob, puas muaj cov kab mob pathogenic tsim cov co toxins? Cov tshuaj lom yog cov muaj zog molecules ua los ntawm ib tug loj ntau yam ntawm kab mob kab mob uas lub hom phiaj host cells thiab ua lub luag haujlwm tseem ceeb hauv tus tswv tsev- kab mob dialog. Lawv yog cov kab mob virulence loj feem ntau txaus los txiav txim siab qhov tshwm sim ntawm kev kis tus kab mob.
Ntxiv mus, dab tsi yog ob chav loj ntawm cov kab mob co toxins?
Ntawm qib tshuaj lom neeg, muaj ob hom tseem ceeb ntawm cov kab mob hauv lub cev, lipopolysaccharides, uas cuam tshuam nrog cov phab ntsa ntawm cov kab mob Gram-negative, thiab cov protein , uas tso tawm los ntawm cov kab mob hauv cov kab mob thiab tuaj yeem ua rau ntawm cov ntaub so ntswg tshem tawm ntawm qhov chaw ntawm cov kab mob loj hlob.
Dab tsi yog pathogens thiab co toxins?
Qhov sib txawv loj tshaj ntawm Pathogens thiab Toxins yog li Kab mob yog cov kab mob microorganisms thiab yog li no tuaj yeem piav qhia thaum nyob toxins tsuas yog los ntawm cov khoom ntawm cov kab mob thiab tsis nyob. Tus kab mob Ebola thiab kab mob Bubonic Plague yog cov piv txwv ntawm kab mob (raws li lawv nyob).

Cov kab mob tseem ceeb ntawm kev txhawj xeeb thaum tham txog cov txheej txheem cov kab mob hauv cov ntshav yog dab tsi?
Cov kab mob tseem ceeb ntawm kev txhawj xeeb yog tib neeg kev tiv thaiv kab mob tsis zoo (HIV), kab mob siab B (HBV), thiab kab mob siab C (HCV). Cov neeg ua haujlwm thiab cov tswv ntiav haujlwm yuav tsum ua kom muaj txiaj ntsig ntawm kev tswj hwm kev tsim vaj tsev thiab kev ua haujlwm txhawm rau tiv thaiv kom tsis txhob muaj ntshav thiab lwm yam kua hauv lub cev
Qhov twg yog tus kab mob sib deev ntau tshaj plaws uas yog tshwm sim los ntawm cov kab mob thiab qee zaum ua rau mob tso zis hauv tus txiv neej?
Epididymitis feem ntau tshwm sim los ntawm kev kis kab mob, suav nrog kev sib deev sib kis (STIs), xws li tus kab mob gonorrhea lossis chlamydia
Dab tsi yog cov kab mob thiab cov kab mob uas cuam tshuam rau cov kab mob integumentary?
Cov pob txuv cuam tshuam nrog qhov txhaws ntawm qhov pores, uas tuaj yeem ua rau muaj kab mob thiab mob, thiab feem ntau pom hauv cov tub ntxhais hluas. Lwm yam kab mob, tsis tau tham txog ntawm no, suav nrog seborrheic dermatitis (ntawm tawv taub hau), psoriasis, mob khaub thuas, impetigo, kab mob khaus, khaus khaus, thiab pob tw
Cov kab mob dab tsi tuaj yeem yog antigenic hauv cov kab mob?
Ntau cov kab mob muaj pili, cov tuab tuab zoo li txuas ntxiv lossis fimbriae, luv "cov plaub hau zoo li" cov qauv uas nthuav tawm los ntawm cov kab mob ntawm cov kab mob ntawm tes thiab pab kho kom haum raws cov kab mob los tuav cov chaw ntawm tes. Kev cuam tshuam ntawm cov tswv tsev hlwb yog cov txheej txheem nyuaj uas cuam tshuam nrog kev nthuav dav ntawm cov protein uas pab txhawb kev nkag mus
Cov kab mob co toxins ua los ntawm cov kab mob dab tsi?
Ntau cov kab mob hauv cov kab mob yog cov protein, sau los ntawm cov kab mob hauv cov kab mob chromosomal, plasmids lossis phages. Lysogenic phages tsim ib feem ntawm chromosome. Cov co toxins feem ntau yog tso tawm los ntawm cov kab mob los ntawm lysis, tab sis qee qhov yog los nrog cov txheej txheem membrane txheej hauv cov txheej membrane vesicles
