TY - JOUR T1 - Evaluation of ten commercial blood culture systems to isolate a pyridoxal-dependent streptococcus. JF - Journal of Clinical Pathology JO - J Clin Pathol SP - 930 LP - 934 DO - 10.1136/jcp.34.8.930 VL - 34 IS - 8 AU - G S Tillotson Y1 - 1981/08/01 UR - http://jcp.bmj.com/content/34/8/930.abstract N2 - This study evaluated the ability of ten commercial blood cultures to support the growth of a nutritional variant Streptococcus mitior (pyridoxal-dependent). The abilities of two established and two new agar formulations are also reported. The dependable isolation of a fastidious streptococcus can best be obtained with fastidious anaerobe broth (FAB) (Lab M Ltd, Ford Lane, Salford) for blood cultures in conjunction with one of the new media. FAB agar with the addition of heated blood was found to support the growth of pyridoxal-dependent Strep mitior and other fastidious organisms. ER -
