Chemical And Toxicological Characterization Of The Upper York River, Virginia The Mattaponi And Pamunkey Rivers, Morris H. Roberts Jr., Mark Richards, Peter F. Delisle Dec 2004

Chemical And Toxicological Characterization Of The Upper York River, Virginia The Mattaponi And Pamunkey Rivers, Morris H. Roberts Jr., Mark Richards, Peter F. Delisle

Reports

This study describes the most extensive effort to characterize the chemistry, toxicology and community of the sediments of the Mattaponi and Pamunkey Rivers. This was accomplished using a study design modified to expand the number of stations occupied by reducing the cost of analyses by compositing replicate samples collected from each study site rather than performing toxicity tests on these samples individually. In previous studies, the variability in field replicate samples was equivalent to the variability in laboratory replicates. This design has long been used to analyze samples for various chemical contaminants as a cost savings endeavor. More ....

Parasitism In Species Of Bathymodiolus (Bivalvia : Mytilidae) Mussels From Deep-Sea Seep And Hydrothermal Vents, Me Ward, Jd Shields, Cl Van Dover Nov 2004

Parasitism In Species Of Bathymodiolus (Bivalvia : Mytilidae) Mussels From Deep-Sea Seep And Hydrothermal Vents, Me Ward, Jd Shields, Cl Van Dover

VIMS Articles

Bivalve species, especially mussels, are biomass dominants in many deep-sea chemosynthetic ecosystems. As in shallow-water environments, parasites are likely to be important factors in the population dynamics of bivalve communities in chemosynthetic ecosystems, but there has been little study of parasitism in deep-sea seep or vent molluscs. In this study, Parasite types, diversity, prevalence, infection density and non-infectious indicators of stress or disease as related to host age, reproductive condition, and endosymbiont density were assessed in mussels (Bathmodiolus heckerae) from 2 seep sites and mussels (B. puteoserpentis) from 2 vent sites. We identified 10 microbial or parasitic agents in histological ...


Dinitrogen Fixation And Release Of Ammonium And Dissolved Organic Nitrogen By Trichodesmium Ims101, Mr Mulholland, Da Bronk, Dg Capone Nov 2004

Dinitrogen Fixation And Release Of Ammonium And Dissolved Organic Nitrogen By Trichodesmium Ims101, Mr Mulholland, Da Bronk, Dg Capone

VIMS Articles

Two methods used to measure dinitrogen (N-2) fixation (acetylene reduction and N-15(2) uptake) often result in different N-2 fixation rates. Part of the discrepancy may arise from the observation that Trichodesmium can release a fraction of their recently fixed N-2 as dissolved organic nitrogen (DON) and/or ammonium (NH4+). To resolve outstanding issues regarding N-2 fixation and the production of dissolved combined nitrogen (N) by Trichodesmium, we conducted a comprehensive analysis of N-2 fixation and the production of DON and NH4+ in cultures of Trichodesmium IMS101. We performed N-15(2) uptake experiments in parallel with acetylene (C2H2) reduction assays ...


Real-Time Pcr For Detection And Quantification Of The Protistan Parasite Perkinsus Marinus In Environmental Waters, C Audemard, Ks Reece, Em Burreson Nov 2004

Real-Time Pcr For Detection And Quantification Of The Protistan Parasite Perkinsus Marinus In Environmental Waters, C Audemard, Ks Reece, Em Burreson

VIMS Articles

The protistan parasite Perkinsus marinus is a severe pathogen of the oyster Crassostrea virginica along the east coast of the United States. Very few data have been collected, however, on the abundance of the parasite in environmental waters, limiting our understanding of P. marinus transmission dynamics. Real-time PCR assays with SybrGreen I as a label for detection were developed in this study for quantification of P. marinus in environmental waters with P. marinus species-specific primers and of Perkinsus spp. with Perkinsus genus-specific primers. Detection of DNA concentrations as low as the equivalent of 3.3 x 10(-2) cell per ...

Ultrastructure Of Mycobacterium Marinum Granuloma In Striped Bass Morone Saxatilis, Dt Gauthier, Wk Vogelbein, Ca Ottinger Oct 2004

Ultrastructure Of Mycobacterium Marinum Granuloma In Striped Bass Morone Saxatilis, Dt Gauthier, Wk Vogelbein, Ca Ottinger

VIMS Articles

An emerging epizootic of mycobacteriosis currently threatens striped bass Morone saxatilis populations in Chesapeake Bay, USA. Several species of mycobacteria, including Mycobacterium marinum, species resembling AT. avium, All. gordonae, M. peregrinum, M. scrofulaceum and M. terrae, and the new species M. shottsii have been isolated from diseased and healthy bass. In this study, we describe the ultrastructure of developing M. marinum granulomas in experimentally infected bass over a period of 45 wk. The primary host response to injected mycobacteria was formation of large macrophage aggregations containing phagocytosed bacilli. AT marinum were always contained within phagosomes. Close association of lysosomes with ...


Infection Dynamics Of Marteilia Refringens In Flat Oyster Ostrea Edulis And Copepod Paracartia Grani In A Claire Pond Of Marennes-Oleron Bay, C Audemard, Mc Sajus, Et Al Oct 2004

Infection Dynamics Of Marteilia Refringens In Flat Oyster Ostrea Edulis And Copepod Paracartia Grani In A Claire Pond Of Marennes-Oleron Bay, C Audemard, Mc Sajus, Et Al

VIMS Articles

The protozoan parasite Marteilia refringens has been partly responsible for the severe decrease in the production of the European flat oyster Ostrea edulis Linnaeus in France since the 1970s. The calanoid copepod Paracartia grani Sars was recently found to be a host for M refringens in French shallow-water oyster ponds ('claires'). This study reconsidered M refringens transmission dynamics in the light of this finding, taking into account not only oyster infection dynamics and environmental factors but also data concerning the copepod host. P. grani population dynamics in the claire under study revealed that this species is the dominant planktonic copepod ...

Isolation And Characterization Of Mycobacteria From Striped Bass Morone Saxatilis From The Chesapeake Bay, Mw Rhodes, H Kator, I Kaattari, D Gautier, W Vogelbein, Ca Ottinger

VIMS Articles

Mycobacteriosis in striped bass Morone saxatilis of Chesapeake Bay, USA, was first diagnosed in 1997 based on the presence of granulomatous inflammation and acid-fast bacteria in skin and spleen. To confirm histopathology, bacteriological detection and identification of mycobacteria were begun using splenic tissue from fish with and without skin ulcerations. On the basis of initial studies using a variety of selective and nonselective media, decontamination, homogenization and incubation conditions, a simple and quantitative recovery method using aseptic necropsy of splenic tissue was developed. Optimal recovery was obtained by spread-plating homogenates on Middlebrook 7H10 agar with incubation for 3 mo at ...

Light Dependence Of [H-3]Leucine Incorporation In The Oligotrophic North Pacific Ocean, Mj Church, Hw Ducklow, Da Karl Jul 2004

Light Dependence Of [H-3]Leucine Incorporation In The Oligotrophic North Pacific Ocean, Mj Church, Hw Ducklow, Da Karl

VIMS Articles

The influence of irradiance on bacterial incorporation of [H-3] leucine was evaluated at Station ALOHA in the oligotrophic North Pacific subtropical gyre. Six experiments were conducted on three cruises to Station ALOHA to examine how [H-3]leucine incorporation varied as a function of irradiance. Two experiments were also conducted to assess the photoautotrophic response to irradiance (based on photosynthetic uptake of [C-14] bicarbonate) in both the upper and lower photic zones. Rates of [H-3]leucine incorporation responded to irradiance in a photosynthesis-like manner, increasing sharply at low light and then saturating and sometimes declining with increasing light intensity. The influence ...


Microsatellite Marker Development And Analysis In The Eastern Oyster (Crassostrea Virginica): Confirmation Of Null Alleles And Non-Mendelian Segregation Ratios, Ks Reece, Wl Ribeiro, Pm Gaffney, Rb Carnegie, Sk Allen Jul 2004

Microsatellite Marker Development And Analysis In The Eastern Oyster (Crassostrea Virginica): Confirmation Of Null Alleles And Non-Mendelian Segregation Ratios, Ks Reece, Wl Ribeiro, Pm Gaffney, Rb Carnegie, Sk Allen

VIMS Articles

Eighteen microsatellite markers were developed for the Crassostrea virginica nuclear genome, including di-, tri-, and tetranucleotide microsatellite repeat regions that included perfect, imperfect, and compound repeat sequences. A reference panel with DNA from the parents and four progeny of 10 full-sib families was used for a preliminary confirmation of polymorphism at these loci and indications of null alleles. Null alleles were discovered at three loci; in two instances, primer redesign enabled their amplification. Two to five representative alleles from each locus were sequenced to ensure that the targeted loci were amplifying. The sequence analysis revealed not only variation in the ...

Status Of The Major Oyster Diseases In Virginia 2003 A Summary Of The Annual Monitoring Program, Ryan B. Carnegie, Lisa M. Ragone Calvo, Eugene M. Burreson

Reports

Low temperatures and salinities brought abatement in the oyster diseases caused by Perkinsus marinus (Dermo) and Haplosporidium nelsoni (MSX) for the first time since 1998. In the James River, P. marinus prevalences were the lowest they had been since 1998. In summer and fall, when P. marinus is normally most prevalent, it was found in a maximum of 72% of oysters at Wreck Shoal and in less than half the oysters at Horsehead Rock and Point of Shoals. Advanced infections were very rare. Haplosporidium nelsoni had disappeared completely from quarterly James River samples by July

A New Pathogenic Virus In The Caribbean Spiny Lobster Panulirus Argus From The Florida Keys, Jd Shields, Dc Behringer May 2004

A New Pathogenic Virus In The Caribbean Spiny Lobster Panulirus Argus From The Florida Keys, Jd Shields, Dc Behringer

VIMS Articles

A pathogenic virus was diagnosed from juvenile Caribbean spiny lobsters Panulirus argus from the Florida Keys. Moribund lobsters had characteristically milky hemolymph that did not clot. Altered hyalinocytes and semigranulocytes, but not granulocytes, were observed with light microscopy. Infected hemocytes had emarginated, condensed chromatin, hypertrophied nuclei and faint eosinophilic Cowdry-type-A inclusions. In some cases, infected cells were observed in soft connective tissues. With electron microscopy, unenveloped, nonoccluded, icosahedral virions (182 +/- 9 nm SD) were diffusely spread around the inner periphery of the nuclear envelope. Virions also occurred in loose aggregates in the cytoplasm or were free in the hemolymph. Assembly ...

Nuclear Export Of The Oncoprotein V-Erba Is Mediated By Acquisition Of A Viral Nuclear Export Sequence, Laura J. Delong, Ghislain M C Bonamy, Erin N. Fink, Lizabeth A. Allison Apr 2004

Nuclear Export Of The Oncoprotein V-Erba Is Mediated By Acquisition Of A Viral Nuclear Export Sequence, Laura J. Delong, Ghislain M C Bonamy, Erin N. Fink, Lizabeth A. Allison

Biology Articles & Book Chapters

v-ErbA, an oncogenic derivative of the thyroid hormone receptor alpha(TRalpha) carried by the avian erythroblastosis virus, contains several alterations including fusion of a portion of avian erythroblastosis virus Gag to its N terminus, N- and C-terminal deletions, and 13 amino acid substitutions. Nuclear export of v-ErbA occurs through a CRM1-mediated pathway. In contrast, nuclear export of TRalpha and another isoform, TRbeta, is CRM1-independent. To determine which amino acid changes in v-ErbA confer CRM1-dependent nuclear export, we expressed a panel of green and yellow fluorescent protein-tagged mutant and chimeric proteins in mammalian cells. The sensitivity of subcellular trafficking of these ...
