Comparison of two commercially available media for detection of bacteremia.
An analysis of 3,795 positive blood cultures obtained from 1,718 patients in a 2.5-year evaluation of Tryptic Soy Broth (TSB) and Thiol Broth is reported. Isolation rates of Actinobacillus and Pseudomonas were significantly greater in TSB, whereas isolation rates of Streptococcus and Corynebacterium (aerobic and anaerobic) were significantly greater in Thiol. Otherwise, the two media were similar. Disregarding contaminants, anaerobic bacteria represented 11% of positive cultures and 20% of patients with bacteremia. Eleven per cent of the patients had polymicrobial bacteremia.
