The Siderophore 2,3-Dihydroxybenzoic Acid Is Not Required For Virulence Of Brucella Abortus In Balb/C Mice, Bryan H. Bellaire, Philip H. Elzer, Cynthia L. Baldwin, R. Martin Roop Jan 1999

The Siderophore 2,3-Dihydroxybenzoic Acid Is Not Required For Virulence Of Brucella Abortus In Balb/C Mice, Bryan H. Bellaire, Philip H. Elzer, Cynthia L. Baldwin, R. Martin Roop

Faculty Publications

2,3-Dihydroxybenzoic acid (DHBA) is the only siderophore described for Brucella, and previous studies suggested that DHBA might contribute to the capacity of these organisms to persist in host macrophages. Employing an isogenic siderophore mutant (ΔentC) constructed from virulent Brucella abortus 2308, however, we found that production of DHBA is not required for replication in cultured murine macrophages or for the establishment and maintenance of chronic infection in the BALB/c mouse model.

Acute Clinical Disease In Cats Following Infection With A Pathogenic Strain Of Bartonella Henselae (Lsu16), Kathy L. O'Reilly, Rudy W. Bauer, Rebecca L. Freeland, Lane D. Foil, Keith J. Hughes, Kristen R. Rohde, Alma F. Roy, Rhett W. Stout, Patricia C. Triche

Faculty Publications

Bartonella henselae is the causative agent of human cat scratch disease as well as several serious sequelae of infections, including bacillary angiomatosis and bacillary peliosis. Conflicting reports describe the pathogenesis of B. henselae in the cat. In this study, we characterized a strain of B. henselae termed LSU16. This strain was isolated on rabbit blood agar from a naturally infected 10-month-old female cat during a recurrent episode of bacteremia. The bacterial species was confirmed by PCR- restriction fragment length polymorphism analysis. Nine cats were infected intradermally with 5 x 107 CFU of LSU16, and clinical signs, antibody responses, and bacteremia …

Separation Of Saturated And Unsaturated Free Fatty Acids Using Capillary Electrophoresis With Indirect Photometric Detection, F. Haddadian, S. A. Shamsi, I. M. Warner Jan 1999

Separation Of Saturated And Unsaturated Free Fatty Acids Using Capillary Electrophoresis With Indirect Photometric Detection, F. Haddadian, S. A. Shamsi, I. M. Warner

Faculty Publications

The capillary zone electrophoresis separation of various mixtures of saturated and unsaturated free fatty acids (FFAs) is performed using adenosine monophosphate (AMP) as an indirect photometric detection reagent. The presence of Brij in the electrolyte and a temperature of 40°C in the running buffer are required to improve solubility of the very long chain FFAs. The separation of C12-C31 differing by only one carbon is achieved using N-methylformamide (NMF)-dioxane (3:2), 40mM Tris, 2.5mM AMP, and 0.5% (w/v) Brij in approximately 40 min. However, baseline resolution of unsaturated isomers of FFAs (C14-C22) requires the presence of water, because water enhances the …

Zim1, A Maternally Expressed Mouse Kruppel-Type Zinc-Finger Gene Located In Proximal Chromosome 7, Joomyeong Kim, Xiaochen Lu, Lisa Stubbs Jan 1999

Zim1, A Maternally Expressed Mouse Kruppel-Type Zinc-Finger Gene Located In Proximal Chromosome 7, Joomyeong Kim, Xiaochen Lu, Lisa Stubbs

Faculty Publications

In analysis of a conserved region of proximal mouse chromosome 7 and human chromosome 19q, we have isolated a novel mouse gene, Zim1 (imprinted zinc-finger gene 1), encoding a typical Kruppel-type (C2H2) zinc-finger protein, located within 30 kb of a known imprinted gene, Peg3 (paternally expressed gene 3). Our studies demonstrate that Zim1 is also imprinted; the gene is expressed mainly from the maternal allele and at high levels only during embryonic and neonatal stages. In contrast to most tissues, Zim1 is expressed biallelically in neonatal and adult brain with slightly more input from the maternal allele. Zim1 produces multiple …

Ferric Iron Reduction By Bacteria Associated With The Roots Of Freshwater And Marine Macrophytes, G. M. King, Meredith A. Garey Jan 1999

Ferric Iron Reduction By Bacteria Associated With The Roots Of Freshwater And Marine Macrophytes, G. M. King, Meredith A. Garey

Faculty Publications

In vitro assays of washed, excised roots revealed maximum potential ferric iron reduction rates of >100 μmol g (dry weight)-1 day-1 for three freshwater macrophytes and rates between 15 and 83 μmol (dry weight)-1 day-1 for two marine species. The rates varied with root morphology but not consistently (fine root activity exceeded smooth root activity in some but not all cases). Sodium molybdate added at final concentrations of 0.2 to 20 mM did not inhibit iron reduction by roots of marine macrophytes (Spartina alterniflora and Zostera marina). Roots of a freshwater macrophyte, Sparganium eurycarpum, that were incubated with an analog …

Complementation Of Conjugation Functions Of Streptomyces Lividans Plasmid Pij101 By The Related Streptomyces Plasmid Psb24.2, Gregg S. Pettis, Shubha Prakash Jan 1999

Complementation Of Conjugation Functions Of Streptomyces Lividans Plasmid Pij101 By The Related Streptomyces Plasmid Psb24.2, Gregg S. Pettis, Shubha Prakash

Faculty Publications

A database search revealed extensive sequence similarity between Streptomyces lividans plasmid pIJ101 and Streptomyces plasmid pSB24.2, which is a deletion derivative of Streptomyces cyanogenus plasmid pSB24.1. The high degree of relatedness between the two plasmids allowed the construction of a genetic map of pSB24.2, consisting of putative transfer and replication loci. Two pSB24.2 loci, namely, the cis-acting locus for transfer (clt) and the transfer-associated korB gene, were shown to be capable of complementing the pIJ101 clt and korB functions, respectively, a result that is consistent with the notion that pIJ101 and the parental plasmid pSB24.1 encode highly similar, if not …

Rapid Evolution Of Fertilization Selectivity And Lysin Cdna Sequences In Teguline Gastropods, Michael E. Hellberg, Victor D. Vacquier Jan 1999

Rapid Evolution Of Fertilization Selectivity And Lysin Cdna Sequences In Teguline Gastropods, Michael E. Hellberg, Victor D. Vacquier

Faculty Publications

Proteins mediating intercellular recognition face opposing selective forces as they evolve: purifying selection to maintain function, and diversifying selection to alter specificity. Lysin is a 16-kDa protein which enables sperm of free-spawning marine snails to make a hole in the vitelline layer (VE) surrounding conspecific eggs. Previous work on abalone (Haliotis spp.) has shown that positive selection promotes rapid interspecific divergence of lysin. Here, we present data on the specificity of VE dissolution by four species of teguline gastropods, along with lysin cDNA sequences. The teguline and abalone lineages diverged over 250 MYA. As in abalone, VE dissolution by lysin …

Maximum-Likelihood Generalized Heritability Estimate For Blood Pressure In Nigerian Families, Charles N. Rotimi, Richard S. Cooper, Guichan Cao, Olufemi Ogunbiyi, Modupe Ladipo, Eme Owoaje, Ryk Ward

Faculty Publications

Elevated blood pressure (BP) is more common in relatives of hypertensives than in relatives of normotensives, indicating familial resemblance of the BP phenotypes. Most published studies have been conducted in westernized societies. To assess the ability to generalize these estimates, we examined familial patterns of BP in a population-based sample of 510 nuclear families, including 1552 individuals (320 fathers, 370 mothers, 475 sons, and 387 daughters) from Ibadan, Nigeria. The prevalence of obesity in this community is low (body mass index: fathers 21.6; mothers, 23.6; sons, 19.2; and daughters=21.0 kg/m2). The BP phenotype used in all analyses was created from …

By virtue of its potential effects on rates of energy expenditure, uncoupling protein 3 (UCP3) is an obesity candidate gene. We identified nine sequence variants in UCP3, including Va19Met, Val102Ile, Arg282Cys, and a splice site mutation in the intron between exons 6 and 7. The splice mutation results in an inability to synthesize mRNA for the long isoform (UCP3L) of UCP3. Linkage (sib pair), association, and transmission disequilibrium testing studies on 942 African-Americans did not suggest a significant effect of UCP3 on body composition in this group. In vastus lateralis skeletal muscle of individuals homozygous for the splice mutation, no …

Effects Of Heat-Sensitive Agents, Soil Type, Moisture, And Leaf Surface On Persistence Of Anticarsia Gemmatalis (Lepidoptera: Noctuidae) Nucleopolyhedrovirus, F. Peng, J. R. Fuxa, A. R. Richter, S. J. Johnson

Faculty Publications

In a laboratory experiment, persistence of Anticarsia gemmatalis Hubner nucleopolyhedrovirus (AgNPV) was significantly lower in marsh soil than in agricultural soil. AgNPV was inactivated significantly more quickly in soil at -0.3 bar water potential than in soil at water potentials of 0 bar or -5 bar. Loss of AgNPV activity was significantly faster in unautoclaved soil than in autoclaved soil. AgNPV stored in unautoclaved marsh water lost 99% of its activity within 64 d, whereas AgNPV in distilled water or autoclaved marsh water remained 98-99% active after the same time period. The soil and marsh-water results indicate that 1 or …

Susceptibility Of Different Instars Of European Corn Borer (Lepidoptera: Crambidae) To Diet Containing Bacillus Thuringiensis, Fangneng Huang, Lawrent L. Buschman, Randall A. Higgins

Faculty Publications

The relative susceptibility of different instars of the European corn borer, Ostrinia nubilalis (Hubner), to a commercial formulation of Bacillus thuringiensis Berliner subsp. kurstaki, Dipel ES, was determined using diet incorporation. European corn borers exposed to Dipel during the 1st instar were much more susceptible than were older larvae. No significant differences in susceptibility were found among 3rd, 4th, and 5th instars at doses of 0.03-0.81 ml of Dipel per kilogram of diet. At high concentrations (2.43 ml/km of diet), 5th instars had significantly lower mortality than did 3rd or 4th instars. The LC50 and LC90 of the 5th instars …

Bromoxynil And Pyrithiobac Weed Control Systems In Transgenic Bxn Cotton., Christopher Brett Corkern

LSU Historical Dissertations and Theses

Field studies conducted in 1996 through 1998 evaluated grass control with the graminicides clethodim, fluazifop-P, quizalofop-P, and sethoxydim alone and in combination with bromoxynil. Sequential application of bromoxynil at 1.7 kg ai/ha 7, 3, and 1 day (d) before or 1, 3, and 7 d after each graminicide reduced antagonism of rhizome johnsongrass [Sorghum halepense (L.) Pers.] control when compared with bromoxynil plus clethodim, fluazifop-P, or quizalofop-P. Antagonism of johnsongrass control associated with bromoxynil and graminicide mixtures reduced cotton yield 17%. A 3 d or greater interval between bromoxynil and graminicide application was necessary to maximize cotton yield. Bromoxynil at …

Physicochemical Influences On Parasites Of Age-0 Largemouth Bass In The Atchafalaya River Basin, Louisiana, Randy C. Landry, William E. Kelso

Faculty Publications

We investigated prevalence and intensity patterns of nine parasite taxa in 244 age-0 largemouth bass (Micropterus salmoides) collected from lake (high dissolved oxygen levels), riverine (high current velocities), and swamp (hypoxic canals and bayous) sites (N=6) in the Atchafalaya River Basin during the 1996 flood pulse. Ectoparasites were dominated by monogenetic trematodes (prevalence=100%; median intensities 27–91 per host) and glochidia (prevalence > 96% at all sites, median intensities 47–148 per host), whereas Posthodiplostomum minimum (Trematoda), Caecincola spp. (Trematoda; C. parvulus and perhaps C. latostoma), Neoechinorhynchus cylindratus (Acanthocephala), and Proteocephalus ambloplitis (Cestoda) accounted for 94.6% of bass endoparasites.

Bird Communities In Two Types Of Anthropogenic Successional Vegetation In Central Amazonia, Sérgio Henrique Borges, Philip C. Stouffer Jan 1999

Bird Communities In Two Types Of Anthropogenic Successional Vegetation In Central Amazonia, Sérgio Henrique Borges, Philip C. Stouffer

Faculty Publications

When primary forest in central Amazonia is cut and abandoned, the plant succession is dominated by Cecropia spp., whereas when it is cut and burned for pastures, the regrowth vegetation is dominated by Vismia spp. The bird communities of these two regrowth forest types were sampled at six sites (9-13 years old) using mist-nets and observations. Bird species richness was similar between the two forest types. Cecropia regrowth, however, was richer for strictly forest bird species than was Vismia regrowth. Mixed-flock species and ant-following birds were significantly more abundant in the Cecropia second growth, whereas nonforest insectivores and omnivores were …

The Values-Ethical Dimension: Do Bsw Students In State-Supported And Religiously Affiliated Programs Differ?, Wade Milton Tyler

LSU Historical Dissertations and Theses

Although an important aspect of any baccalaureate social work program is the inculcation of social work values, there has not been an abundance of studies in this area. Many of those that exist have been criticized for their methodology in measuring values. It is appropriate to examine that which has been termed the "fulcrum" of social work practice relative to the educational processes which purport to put that fulcrum in place. The purpose of this study was to compare BSW students in religiously-affiliated institutions of higher education with those in state-supported institutions on three dimensions: adherence to social work values, …

On Biodata Construct Validity, Criterion-Related Validity, And Adverse Impact., Michelle Ann Dean

LSU Historical Dissertations and Theses

This study examined the personnel selection technique of biographical information (biodata) in terms of theory, criterion-related validity, and adverse impact. First, the construct validity of biodata was examined to determine if biodata theory was useful in explaining biodata's strong criterion validity. Items from an existing biodata inventory were mapped onto construct domains drawn from Mumford, Stokes, and Owens' (1990) ecology model. Relationships between subjects' biodata responses and training performance was examined for consistency with the model's predictions in an organizational sample. The ecology model did not fit the data well. Follow up exploratory analyses did yield good fit when the …

Ernest Renan And The Question Of Race., Jane Victoria Dagon Jan 1999

Ernest Renan And The Question Of Race., Jane Victoria Dagon

LSU Historical Dissertations and Theses

Racism in France can be traced back to the 1560's when the nobles claimed to be of a separate race in order to obtain special rights and privileges. Soon after in the seventeenth century, scientists started to classify humans according to physical features. With the increase in travel, the slave trade, the fear of the unknown and the fear of contamination, these factors along with physiognomy and phrenology encouraged "biological racism." During the second half of the nineteenth century, Ernest Renan (1823--1892) denounces biological racism and the existence of the so-called "pure races." He is also the first dramatist to …
