Phage H, thought to be specific for Pasteurella pestis, was shown to plate efficiently on F(-) strains of Escherichia coli but not on F(+), F', or Hfr strains. The phage was adsorbed rapidly to F(-) strains but was not adsorbed to strains carrying F. Comparison with seven other reported female-specific phages showed that, although phage H was similar to the… (More)
In this paper, we propose a probabilistic approach for foreground segmentation in 360 •-view-angle range data sequences, recorded by a rotating multi-beam Lidar sensor, which monitors the scene from a fixed position. To ensure real-time operation, we project the irregular point cloud obtained by the Lidar, to a cylinder surface yielding a depth image on a… (More)

Bacteriol. 84:147-153. 1962-Bacillus cereus produced toxin in a Casamino acids medium without added serum or other protein. The toxin was separated into two components… (More)
Bacteriophage P1 CM can convert Pasteurella pestis or P. pseudotuberculosis to chloramphenicol resistance and phage restriction, but no viable phage was induced from converted Pasteurella strains.
When either the F' lac or the F'Cm plasmid was transferred from Escherichia coli into Pasteurella pseudotuberculosis, the P. pseudotuberculosis (F') strains isolated formed plaques with both ribonucleic acid (RNA)-containing and deoxyribonucleic acid-containing male-specific phages. In contrast, strains of P. pestis harboring E. coli (F') plasmids did not… (More)
