Similarity between copper resistance genes from Xanthomonas campestris and Pseudomonas syringae
(American Society for Microbiology, 1993-05)
Plasmid-borne copper resistance genes from copper-resistant strains of Xanthomonas campestris pv. vesicatoria from California, Florida, and Oklahoma shared structural similarities. A strain of X. campestris pv. campestris ...
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 ...
Prior blood feeding effects on susceptibility of Anopheles gambiae (Diptera: Culicidae) to infection with cultured Plasmodium falciparum (Haemosporida: Plasmodiidae)
(Oxford University Press (OUP), 1994)
We examined the relative susceptibilities of Anopheles gambiae Giles of different physiological ages to infection with cultured Plasmodium falciparum (Welch). Cohorts of mosquitoes were divided into three groups; one was ...
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 ...
Characterization and transcriptional analysis of the gene cluster for coronafacic acid, the polyketide component of the phytotoxin coronatine
(American Society for Microbiology, 1995-11)
Coronafacic acid (CFA), the polyketide component of the phytotoxin coronatine (COR), is activated and coupled to coronamic acid via amide bond formation, a biosynthetic step presumably catalyzed by the CFA ligase (cfl) ...
Eu-doped CaF2 grown on Si(100) substrates by molecular beam epitaxy
(AIP Publishing, 1995-09-25)
Eu is incorporated into CaF2 films grown on Si(100) by molecular beam epitaxy using elemental Eu evaporation. Eu doping as high as 4.05 at. % does not significantly degrade the surface morphology, indicating a relatively ...
Evidence for phage-mediated gene transfer among Pseudomonas aeruginosa strains on the phylloplane
(American Society for Microbiology, 1994-02)
As the use of genetically engineered microorganisms for agricultural tasks becomes more frequent, the ability of bacteria to exchange genetic material in the agricultural setting must be assessed. Transduction (bacterial ...
Development of a rickettsia isolated from an aborted bovine fetus
(American Society for Microbiology, 1990-10)
An obligate intracellular rickettsial organism isolated from an aborted bovine fetus was studied in bovine turbinate and mouse macrophage cell cultures with light and electron microscopy. Development of the organism was ...
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 ...
