Growth kinetics of Salmonella enterica in Hajnatetrathionate broth, Rappaport broth and modified semisolid Rappaport agar

[摘要] References(15)To determine the appropriate method for isolating Salmonellaenterica, we compared the growth of S. enterica serovars usingthree selective enrichment media. S. enterica was more successfullyisolated from artificially contaminated fecal samples after enrichment in Hajnatetrathionate broth or modified semisolid Rappaport agar than in Rappaport broth. Sincemost bacteria (other than motile S. enterica) do not migrate on modifiedsemisolid Rappaport agar, the growth characteristics of S. enterica canbe interpreted easily and quickly. Two S. enterica isolates did notmigrate on modified semisolid Rappaport agar, but did grow in Hajna tetrathionate broth,which suggests that the combined use of these selective enrichment media is appropriatefor isolating S. enterica.
