Evaluation of two commercially available media for detection of bacteremia

Analysis of the results of 13,162 blood cultures during a 9-month interval has shown that Pseudomonas aeruginosa statistically was recovered more frequently from Trypticase soy broth (TSB) than from Thioglycollate-135C and that contaminants, including Staphylococcus epidermidis and aerobic and anaerobic Corynebacterium species, were isolated with statistically greater frequency from Thioglycollate-135C than from TSB. No other statistically significant differences were found.
