Studies on the isolation of Salmonella dublin

Abattoir drain swabs, bovine faeces and a few other veterinary samples were examined for the presence of Salmonella dublin. Three selective agar media and four enrichment broths were investigated. The two most efficient plating media were deoxycholate citrate agar and brilliant green MacConkey agar. Wilson and Blair's bismuth sulphite agar (de Loureiro's modifications) was least successful. Selenite F broth, whether incubated at 37 or 43 degrees C., was better than the other enrichment broths used which contained a triphenyl methane dye as one of the selective ingredients.
