Genetic and immunologic analyses of PlpE, a lipoprotein important in complement-mediated killing of Pasteurella haemolytica serotype 1
(American Society for Microbiology, 1998-12)
Pasteurella haemolytica serotype 1 is the bacterium most commonly associated with bovine shipping fever. The presence of antibodies against P. haemolytica outer membrane proteins (OMPs) correlates statistically with ...
Growth phase and temperature influence promoter activity, transcript abundance, and protein stability during biosynthesis of the Pseudomonas syringae phytotoxin coronatine
(American Society for Microbiology, 1998-03)
The plant-pathogenic bacterium Pseudomonas syringae pv. glycinea PG4180.N9 synthesizes high levels of the polyketide phytotoxin coronatine (COR) at 18°C, whereas no detectable toxin is produced at 28°C. Previously, we ...
Time resolved measurements which isolate the mechanisms responsible for terahertz glory scattering from dielectric spheres
(American Physical Society, 1998-01-12)
The surface-wave scattering processes responsible, in part, for the optical glory have never been compared with theoretical predictions. Here, THz impulse ranging is used to measure the time domain impulse response of ...
Characterization of CorR, a transcriptional activator which is required for biosynthesis of the phytotoxin coronatine
(American Society for Microbiology, 1998-12)
Coronatine (COR) is a plasmid-encoded phytotoxin synthesized by several pathovars of phytopathogenic Pseudomonas syringae. The COR biosynthetic gene cluster in P. syringae pv. glycinea PG4180 is encoded by a 32-kb region ...
Whole-cell kinetics of trichloroethylene degradation by phenol hydroxylase in a Ralstonia eutropha JMP134 derivative
(American Society for Microbiology, 1998-11)
The rate, progress, and limits of trichloroethylene (TCE) degradation by Ralstonia eutropha AEK301/pYK3021 whole cells were examined in the absence of aromatic induction. At TCE concentrations up to 800 uM, degradation ...
Reverse transcriptase PCR amplification of Rickettsia typhi from infected mammalian cells and insect vectors
(American Society for Microbiology, 1998-06)
We developed a reverse transcriptase PCR assay to detect expression of 120- and 17-kDa antigen genes in Rickettsia typhi. Infected Vero cell and flea RNAs were reverse transcribed by using random hexamers. The cDNA was ...
Predicting key malaria transmission factors, biting and entomological inoculation rates, using modelled soil moisture in Kenya
(Wiley, 1998-10)
While malaria transmission varies seasonally, large inter-annual heterogeneity of malaria incidence occurs. Variability in entomological parameters, biting rates and entomological inoculation rates (EIR) have been strongly ...
Trends in the accuracy of USDA production forecasts for beef and pork
(Western Agricultural Economics Association, 1998-12)
Trends in the accuracy of USDA forecasts of beef and pork production and supply are evaluated for the period 1982-96. Findings of the study show that USDA forecasts underestimated production and supply in the 1980s, but ...
Multilayer formation in an azacrown [18]N6 Langmuir film
(Royal Society of Chemistry, 1998)
A neutron reflectivity study of a deuterated azacrown [18]N6 at the air-water interface shows that it forms multilayers upon compression, with monolayers and trilayers being more stable than bilayers.
Influence of light on bacterioplankton production and respiration in a subtropical coral reef
(Inter Research, 1998-02-13)
The influence of sunlight on bacterioplankton production [14C-leucine (Leu) and 3H-thymidine (TdR) incorporation; changes in cell abundances] and O2 consumption was investigated in a shallow subtropical coral reef located ...
