Y. enterocolitica thiab Y. pseudotuberculosis yog cov zaub mov tseem ceeb uas muaj kab mob.Txawm li cas los xij, qhov muaj kev sib tw microbiota ua rau kev sib cais ntawm Y. enterocolitica thiab Y. pseudotuberculosis los ntawm cov khoom noj khoom haus tsis zoo.Peb sim ntsuas qhov kev ua tau zoo ntawm kev hloov kho Cefsulodin-Irgasan-Novobiocin (CIN) agar nyob rau hauv qhov sib txawv ntawm Y. enterocolitica los ntawm non-Yersinia hom, tshwj xeeb tshaj yog cov kab mob hauv plab hnyuv microbiota.Kev hloov kho CIN tau ua kom muaj kev loj hlob ntawm Y. enterocolitica cov cheeb tsam nrog tib qhov ua tau zoo li CIN thiab Luria-Bertani agar.Cov kev txwv tsis pub muaj kev hloov kho CIN rau Y. enterocolitica hauv kab lis kev cai nruab nrab (10 cfu/ml) thiab hauv cov nqaij npuas uas tsis muaj kab mob (10(4) cfu/ml) kuj tau piv rau cov CIN.Txawm li cas los xij, qhov hloov kho CIN tau muab qhov kev ntxub ntxaug zoo dua ntawm Yersinia cov cheeb tsam los ntawm lwm cov kab mob uas nthuav tawm Yersinia zoo li cov cheeb tsam ntawm CIN (H2S-producing Citrobacter freundii, C. braakii, Enterobacter cloacae, Aeromonas hydrophila, Provi dencia rettgeri, thiab Morganella morganii).Qhov hloov kho CIN tau nthuav tawm qhov rov qab zoo dua ntawm Y. enterocolitica los ntawm cov kab mob sib xyaw ua ke thiab cov kab mob kis tau zoo piv nrog CIN.Peb cov txiaj ntsig tau ua pov thawj tias kev siv cov hloov kho CIN tuaj yeem yog ib qho txiaj ntsig zoo los ua kom cov khoom noj rov qab los ntawm Yersinia los ntawm cov qauv ntuj, uas feem ntau yog kis los ntawm ntau hom kab mob.
