The Failure of Brilliant Green and Telluric Acid as Selective Agents for the Isolation ofBacillus typhosusfrom Faeces
Year: 1935
Type: article
Abstract: 1. The causes of failure of the brilliant green enrichment method for isolation ofB. typhosusare discussed. 2. It has been shown that the negative results obtained depend partly on the number of resistantB. colistrains normally present in faeces, and partly on the use of McConkey's as a plating out medium. 3. The alleged selective action of telluric acid could not be confirmed. 4. The so-called antagonism betweenB. coliandB. typhosushas been investigated, and by the use of a selective bismuth medium it is shown that this is more apparent than real in most cases. 5. However, the existence of certain strains ofB. colior similar bacteria with a specific inhibitory effect onB. typhosushas been confirmed. 6. The value of Wilson's bismuth medium for the isolation ofB. typhosushas been demonstrated.
