The BBL Crystal Enteric/Nonfermenter System (Crystal) was used to test 25 archived isolates of Yersinia pestis to obtain a unique biochemical profile code for Y. pestis. The revised Crystal system and the API 20E system were compared by using 12 clinical human isolates of Y. pestis. Crystal correctly identified 11 of the 12 isolates, while API correctly identified 7 of the 12 isolates.

The performance of BBL CHROMagar O157 (CHROM) versus that of sorbitol-MacConkey (SMAC) media for detection of Escherichia coli O157 was determined for a 3-month period. Results for 27/3,116 (0.9%) stool cultures were positive. CHROM had a higher sensitivity (96.30%) and negative predictive value (100%) and a better diagnostic efficiency than SMAC. Labor and material costs decreased when CHROM w...

A total of 52 residual CSF and serum specimens, which were originally negative with the Cryptococcal Antigen Latex Agglutination System (CALAS), were shown to become falsely positive after placement in BBL Port-A-Cul anaerobic transport vials. This transport device, although excellent for specimen transportation for subsequent culture, should not be used if cryptococcal antigen testing is needed.

The probe-based Velogene Rapid MRSA Identification Assay (ID Biomedical Corp., Vancouver, British Columbia, Canada) and the latex agglutination MRSA-Screen (Denka Seiken Co., Tokyo, Japan) were evaluated for their ability to identify methicillin-resistant Staphylococcus aureus (MRSA) and to distinguish strains of MRSA from borderline oxacillin-resistant S. aureus (BORSA; mecA-negative, oxacilli...

Spectral attenuation and absorption coefficients of particulate matter and colocated hydrographic measurements were obtained in the Mid-Atlantic Bight during the fall of 1996 and the spring of 1997 as part of the Coastal Mixing and Optics experiment. Within the bottom boundary layer (BBL) the magnitude of the beam attenuation decreased and its spectral shape became steeper with distance from th...

Brain-Based Learning (BBL) is an instructional approach that addresses students’ achievement and learning goals from the perspective of human brain. It entails specialised procedures centred on how memory, attention, motivation, conceptual cognitive work. The current experimental study was designed to investigate effect BBL elementary academic performance in mathematics. employed a single subje...

The hadronic interaction model BBL implements the ideas of gluon saturation due to large densities. When approaching the black body limit at high energies, leading partons acquire large transverse momenta which breaks up their coherence. This leads to a suppression of forward scattering, and is therefore important for air showers. We discuss some general aspects of this new approach and their i...

This paper presents methodologies for dimensioning access networks based on ATM technology, taking as a case study the Passive Optical Access Network (PON) being developed as part of the Broadband Loop (BBL) project, from the European Program ACTS Advanced Communications Technology and Services.
