BACTEC flask

Clinical blood cultures were collected in the Bactec 8A flask (Johnston Laboratories, Cockeysville, Md.) and examined macrosopically, microscopically, and radiometrically in an effort to determine which approach produced the fastest detection time. Of 360 blood cultures found to contain organisms by subculture, 334 were first detected by Bactec, 98 by macroscopic examination, and 68 by microscopic examination. Examination times were at 4, 8, 16, 24, 36, and 48 h after collection of the specimen. Sixteen hours after specimen collection, microscopic examination had detected 31 positive cultures, macroscopic examination had detected two positive cultures, and Bactec had detected 160 positive cultures. By the end of the first 24 h of incubation, Bactec had detected 313 (93%) of those cultures eventually found to be positive. Although Bactec produced the fastest detection time in an overwhelming majority of the cultures, it failed to detect three of three Candida spp. cultures, three of five Bacteroides spp. cultures, and six of 32 Enterococcus spp. cultures during the first 48 h of incubation.
Growth of both PZA-resistant mutants (bottom rows in Tables 2 and 3) was not inhibited by any of the drug concentrations used for either medium; the mutants showed full resistance to all concentrations used in the BACTEC broth (MIC > 900 µg/ml).
