Mycobacterium chelonei ss abscessus was isolated from a subcutaneous abscess that had been submitted in Bactec blood culture bottles. Detection occurred in three days as compared to seven days in classical mycobacterial media.

A commercially available agar-slide blood culture bottle (Septi-Chek; Roche Diagnostics, Div. Hoffman-La Roche, Inc., Nutley, N.J.) was compared with the radiometric blood culture system (BACTEC; Johnston Laboratories, Inc., Towson, Md.) in 8,544 paired blood cultures from adult patients. The systems were inoculated with equal volumes (10 ml) of blood. Overall, there was no statistically signif...

A single bottle blood culture system that detects the gas produced by micro-organisms from substrates in a specially formulated medium was compared with the Bactec radiometric system. A total of 725 blood samples collected from patients with suspected bacteraemia yielded 75 clinically important isolates. Fifty five (73%) of these cultures were detected by both methods, 16 (21%) by only the Bact...

In two long-term studies, the BACTEC radiometric system for detection of bacteremia was evaluated with three culture media each: (i) BACTEC media 6A (for aerobes) and 7B (for anaerobes) plus a thioglycolate medium and (ii) BACTEC media 6A, 7B, and 8A (hypertonic). In study 1, clinically significant isolates were identified in 1,873 (13.9%) of 13,432 blood cultures with all three media. The thio...
