Noninfectious sporozoites in the salivary glands of a minimally susceptible anopheline mosquito
(American Society of Parasitologists, 1995-12)
In studies to evaluate vector-malaria parasite relationships, we have found that Anopheles albimanus is minimally susceptible to the rodent malaria parasite Plasmodium yoelii. Normally, less than 10% of A. albimanus develop ...
Regulation of alginate biosynthesis in Pseudomonas syringae pv. Syringae
(American Society for Microbiology, 1999-06)
Both Pseudomonas aeruginosa and the phytopathogen P. syringae produce the exopolysaccharide alginate. However, the environmental signals that trigger alginate gene expression in P. syringae are different from those in P. ...
Performance of alternative component pricing systems for pork
(Cambridge University Press, 1998-12)
One method of implementing value-based marketing is a component pricing system. This research develops and evaluates alternative component pricing systems for pork. Two electronic technologies for estimating carcass ...
Molecular identification of Rickettsia typhi and R. felis in co-infected Ctenocephalides felis (Siphonaptera: Pulicidae)
(Oxford University Press (OUP), 1998)
Rickettsia typhi and R. felis, 2 closely related rickettsial species, often have been identified in cat fleas, Ctenocephalides felis (Bouche) from the same geographical location. However, no fleas have been found to be ...
Trap-enhanced electric fields in semi-insulators: The role of electrical and optical carrier injection
(AIP Publishing, 1991-10-14)
We report extremely large field enhancement near the anode of an electrically biased metal/semi-insulator/metal structure. The large anode field results from a trap-enhanced space-charge region and is large enough to cause ...
Resistance of Spiroplasma citri lines to the virus SVTS2 is associated with integration of viral DNA sequences into host chromosomal and extrachromosomal DNA
(American Society for Microbiology, 1995-11)
Spiroplasmavirus SVTS2, isolated from Spiroplasma melliferum TS2, produces plaques when inoculated onto lawns of Spiroplasma citri M200H, a derivative of the type strain Maroc R8A2. S. citri strains MR2 and MR3, originally ...
Study of the response of a biofilm bacterial community to UV radiation
(American Society for Microbiology, 1999-05)
We have developed a bioluminescent whole-cell biosensor that can be incorporated into biofilm ecosystems. RM4440 is a Pseudomonas aeruginosa FRD1 derivative that carries a plasmid-based recA-luxCDABE fusion. We immobilized ...
Plasmodium falciparum: Release of circumsporozoite protein by sporozoites in the mosquito vector
(Elsevier BV, 1992)
The release of circumsporozoite (CS) protein by Plasmodium falciparum sporozoites was investigated to identify factors regulating this process within infected Anopheles gambiae mosquitoes. The potential for sporozoites to ...
Population dynamics of Plasmodium falciparum sporogony in laboratory-infected Anopheles gambiae
(American Society of Parasitologists, 1992)
The population dynamics of cultured Plasmodium falciparum parasites was examined during their sporogonic development in Anopheles gambiae mosquitoes. Estimates of absolute densities were determined for each life stage, and ...
Effects of environmental and nutritional factors on production of the polyketide phytotoxin coronatine by Pseudomonas syringae pv. glycinea
(American Society for Microbiology, 1993-05)
Pseudomonas syringae pv. glycinea PG4180 produces the polyketide phytotoxin coronatine. The effects of environmental, nutritional, and host factors on growth and coronatine production by PG4180 were examined by varying the ...
