Studies of D-D Fusion Reactivity in High-Temperature Jet Plasmas (1991)

Adams, J. M., Balet, B., Boyd, D. A., Campbell, D. J., Challis, C. D., Christiansen, J. P., ...

The D-D fusion reactivity from JET plasmas has been optimized by using combined neutral beam injection and radiofrequency heating. Reaction rates of up to 2.9 x 10(16) reactions per second...

Molecular Characterization of the vanD Gene Cluster and a Novel Insertion Element in a Vancomycin-Resistant Enterococcus Isolated in Canada

Boyd, D. A., Conly, J., Dedier, H., Peters, G., Robertson, L., Slater, E., ...

A single vanD-containing Enterococcus faecium strain (N97-330) was isolated in Canada. The vanD-containing region was cloned and sequenced. Although the proteins have more than 96% identity to a...

Molecular Characterization of the vanE Gene Cluster in Vancomycin-Resistant Enterococcus faecalis N00-410 Isolated in Canada

Boyd, D. A., Cabral, T., Van Caeseele, P., Wylie, J., Mulvey, M. R.

The vanE operon was characterized from Enterococcus faecalis N00-410 (MIC of vancomycin = 24 μg/ml). The organization of the vanE operon was identical to that of the vanC1 operon from Enterococcus...

Glucose transport by a mutant of Streptococcus mutans unable to accumulate sugars via the phosphoenolpyruvate phosphotransferase system.

Cvitkovitch, D G, Boyd, D A, Thevenot, T, Hamilton, I R

Streptococcus mutans transports glucose via the phosphoenolpyruvate (PEP)-dependent sugar phosphotransferase system (PTS). Earlier studies indicated that an alternate glucose transport system...

Sequence, expression, and function of the gene for the nonphosphorylating, NADP-dependent glyceraldehyde-3-phosphate dehydrogenase of Streptococcus mutans.

Boyd, D A, Cvitkovitch, D G, Hamilton, I R

We report the sequencing of a 2,019-bp region of the Streptococcus mutans NG5 genome which contains a 1,428-bp open reading frame (ORF) whose putative translation product had 50% identity to the...

Regulation of sugar transport via the multiple sugar metabolism operon of Streptococcus mutans by the phosphoenolpyruvate phosphotransferase system.

Cvitkovitch, D G, Boyd, D A, Hamilton, I R

In this report, we provide evidence that the transport of sugars in Streptococcus mutans via the multiple sugar metabolism system is regulated by the phosphoenolpyruvate phosphotransferase system. A...

Sequence and expression of the genes for HPr (ptsH) and enzyme I (ptsI) of the phosphoenolpyruvate-dependent phosphotransferase transport system from Streptococcus mutans.

Boyd, D A, Cvitkovitch, D G, Hamilton, I R

We report the sequencing of a 2,242-bp region of the Streptococcus mutants NG5 genome containing the genes for ptsH and ptsI, which encode HPr and enzyme I (EI), respectively, of the...

Haemophilus pleuropneumoniae serotyping.

Rosendal, S, Boyd, D A

A total of 126 Haemophilus strains isolated from porcine pneumonia were serotyped, using the indirect fluorescent-antibody technique. Of these, 103 were successfully typed within the recognized...

Comparative virulence of porcine Haemophilus bacteria.

Rosendal, S, Boyd, D A, Gilbride, K A

The virulence of strains of Haemophilus pleuropneumoniae serotype 1, 2, 3, 7 and strains of the "minor-group" and Haemophilus parasuis were compared by inoculating specific pathogen-free pigs into...
