Qhov sib txawv tseem ceeb ntawm Pasteurella thiab Haemophilus yog Paeteurella yog ib hom kab mob gram-negative facultative anaerobic bacteria uas yog cov kab mob zoonotic thaum Haemophilus yog ib hom kab mob gram-negative, pleomorphic, coccobacilli cov kab mob uas xav tau ntshav rau kev loj hlob.
Pasteurellaceae yog tsev neeg loj ntawm gram-negative facultative anaerobic kab mob. Tsis tas li ntawd, lawv yog tus pas nrig-puab obligatory kab mob parasitic. Lawv tsis muaj flagella. Yog li ntawd, lawv yog cov tsis ua hauj lwm. Tsis tas li ntawd, lawv yog cov kab mob commensal ntawm cov kab mob ua pa ntawm cov noog thiab tsiaj txhu. Txawm li cas los xij, feem ntau ntawm cov kab mob ua rau cov kab mob kis tau zoo. Muaj 13 genera nyob rau hauv cov kab mob no. Ntawm lawv, Pasteurella thiab Haemophilus yog ob lub npe zoo tshaj plaws, uas muaj ntau hom tsiaj txhu tseem ceeb. Lawv muaj cov txheej txheem txheej txheej uas feem ntau yog lipopolysaccharides. Lawv cov kab mob pathogenic feem ntau cuam tshuam nrog lipopolysaccharide (LPS) lossis lipooligosaccharide (LOS), adhesins, capsules, cov tshuab tau hlau, thiab cov co toxins.
Pasteurella yog dab tsi?
Pasteurella yog ib hom kab mob gram-negative, facultative anaerobic bacteria. Lawv yog cov kab mob ntawm Pasteurellales thiab tsev neeg ntawm Pasteurellaceae. Pasteurella hom yog tsis-motile, non-spore forming thiab pleomorphic. Lawv nthuav tawm bipolar staining nta lossis kev nyab xeeb tus pin zoo li. Ntxiv mus, ntau hom ntawm cov genus no yog catalase thiab oxidase zoo.
Daim duab 01: Pasteurella
hom Pasteurella yog cov kab mob zoonotic. Tib neeg tau kis tus kab mob Pasteurella feem ntau los ntawm kev tom, khawb, lossis licks ntawm cov tsiaj hauv tsev. Lawv nyob ua ib feem ntawm cov nroj tsuag ntawm lub qhov ntswg thiab qhov ncauj ntawm ntau cov tsiaj nyeg, nqaij qaib, thiab cov tsiaj hauv tsev, tshwj xeeb tshaj yog cov dev thiab miv. P. multocida yog hom kab mob uas ua rau muaj kab mob rau tib neeg. Txij li cov hom Pasteurella yog tshuaj tua kab mob, lawv tuaj yeem tswj tau los ntawm cov tshuaj tua kab mob xws li chloramphenicol, penicillin, tetracycline, enrofloxacin, oxytetracycline, ampicillin thiab macrolides.
YHemophilus yog dab tsi?
Haemophilus yog lwm genus ntawm tsev neeg Pasteurellaceae. Haemophilus hom yog cov kab mob gram-negative facultative anaerobic kab mob uas yog pleomorphic thiab tsis-motile. Lawv yog coccobacilli zoo li cov kab mob pathogenic bacilli. Ntxiv mus, lawv yog cov kab mob uas tsis muaj kab mob. Cov kab mob no xav tau hemin thiab los yog nicotinamide adenine dinucleotide (NAD+) (factor V) rau kev loj hlob. Vim xav tau ntshav thaum lub sij hawm loj hlob, lawv tau muab lub npe Haemophilus.
Daim duab 02: Haemophilus spp.
Haemophilus hom yog tib neeg cov kab mob uas ua rau cov kab mob bacteremia, pneumonia, meningitis thiab chancroid. Txawm li cas los xij, lawv cov pathogenicity tsis cuam tshuam nrog kev tsim cov tshuaj lom lossis lwm yam khoom siv ntxiv.
Dab tsi zoo sib xws ntawm Pasteurella thiab Haemophilus?
- Pasteurella thiab Haemophilus yog ob hom kab mob gram-negative facultative anaerobic bacteria.
- Lawv muaj rau kev txiav txim: Pasteurellales thiab tsev neeg: Pasteurellaceae.
- Ob lub genera qhia ib lub koom haum polyphyletic.
- Lawv yog cov kab mob zoo li tus kab mob.
- Tsis tas li, lawv yog pleomorphic, nonmotile thiab non-spore tsim cov kab mob.
Qhov txawv ntawm Pasteurella thiab Haemophilus yog dab tsi?
Pasteurella yog ib hom kab mob gram-negative facultative anaerobic pleomorphic kab mob uas yog cov kab mob zoonotic thaum Haemophilus yog ib hom kab mob gram-negative, pleomorphic, coccobacilli uas xav tau ntshav rau kev loj hlob. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm Pasteurella thiab Haemophilus. Tsis tas li ntawd, hom Pasteurella ua rau cov kab mob ua pa sab saud feem ntau hauv tib neeg thaum Haemophilus hom ua rau cov kab mob bacteremia, pneumonia, meningitis thiab chancroid.
Summary – Pasteurella vs Haemophilus
Pasteurella thiab Haemophilus yog ob hom ntawm tsev neeg Pasteurellaceae. Cov tswv cuab ntawm ob hom no yog gram-negative, rod-shaped, facultative anaerobic bacteria uas yog pleomorphic thiab non-motile. Haemophilus hom xav tau ntshav rau kev loj hlob. Ob hom kab mob yog tib neeg cov kab mob. Cov kab mob Pasteurella ua rau kab mob ua pa sab sauv thaum Haemophilus hom ua rau cov kab mob bacteremia, mob ntsws, mob meningitis thiab chancroid. Yog li, qhov no qhia txog qhov sib txawv ntawm Pasteurella thiab Haemophilus.
