Y. enterocolitica et Y. pseudotuberculosis magni momenti sunt cibus pathogens.Nihilominus praesentia microbiota competitive facit solitudinem enterocoliticam et Y. pseudotuberculosis a cibis naturaliter contaminatis difficilis.Agar Cefsulodin-Irgasan-Novobiocin (CIN) perpendere conati sumus in differentiatione Y. enterocoliticae a speciebus non-Yersinia, praesertim microbiota intestinali naturali.Modificatum CIN incrementum coloniarum enterocoliticorum Y. eadem efficacia quam CIN et Luria-Bertani agar donavit.Deprehensio limites mutationis CIN pro Y. enterocoliticis in cultura medii (10 cfu/ml) et in suilla artificiose contaminata (10(4) cfu/ml) comparati sunt etiam illis CIN.Sed mutatio CIN melius discrimen coloniarum Yersinia praebebat ab aliis bacteria exhibens Yersinia-similes colonias in CIN (H2S-producens Citrobacter freundii, C. braakii, Enterobacter cloacae, Aeromonas hydrophila, Provi dencia rettgeri, et Morganella morganii).Mutatio CIN exhibebat ratem receptam altiorem Y. enterocoliticam ex culturas bacterial arte praeparata et exempla naturaliter contaminata cum CIN comparata.Proventus noster ita demonstravit usum mutationis CIN esse validum medium ad augendum cibum receptam in Yersinia ex speciminibus naturalibus, quae pluribus speciebus bacteria contaminari solent.
