Comparison of two liquid blood culture media containing sodium polyanethole sulfonate: tryptic soy and Columbia.
In a comparison of tryptic soy broth and Columbia broth, two blood culture media containing sodium polyanetholesulfonate, there were 589 positive cultures (excluding presumed contaminants). The two media were equivalent in performance except for lower detection rates for Staphylococcus aureus (P < 0.01) and Pseudomonas aeruginosa (P = 0.05) and a higher detection rate for Bacillus (P < 0.01) in Columbia broth. No significant differences were noted in time intervals to detection of positivity. Routine subcultures on the 1st and 5th days of incubation provided the initial detection of 18.1% of the positive cultures.
