Biofilm formation by the fish pathogen Flavobacterium columnare: a quantitative and qualitative study

Cai, Wenlong (2013-04-30)

The objective of this study was to evaluate the effect that temperature, pH, salinity, hardness and carbohydrates have on biofilm formation by the fish pathogen Flavobacterium columnare. Nineteen F. columnare strains, ...

Characterization of Innate Immune Genes of Catfish: CXC Chemokines and Toll-Like Receptors

Baoprasertkul, Puttharat (2006-05-15)

Innate immunity is known as the first line of defense against pathogenic invasions. Fish, as lower vertebrates, are believed to maintain their healthy status mostly by relying on their innate immunity. Of the many types ...

A Comparative Investigation of Streptococcus Agalactiae Isolates from Fish and Cattle

Garcia, Julio (2007-05-15)

Streptococcus agalactiae is the causative bacterium of streptococcosis and causes severe economic losses in wild and cultured fish and cattle, worldwide. In fish, infection can result in septicemia with hemorrhages on the ...

Development, Characterization and Early Evaluation of New Modified Live Vaccines Against Columnaris Disease

Olivares-Fuster, Oscar (2010-04-07)

Columnaris disease is an acute to chronic bacterial infection that affects commercial aquaculture and the ornamental fish industry. Flavobacterium columnare, causal agent of columnaris disease, is a facultative pathogen ...

Discovery, Isolation and Characterization of Bacteriophages Specific for Edwardsiella ictaluri

Walakira, John (2008-05-15)

Two novel bacteriophages that infect Edwardsiella ictaluri, the causative agent of enteric septicemia of catfish (ESC), were isolated from aquaculture pond water and from a diseased channel catfish. Both phages (FeiDWF and ...

Disruption of Embryonic Development in Channel Catfish, Ictalurus Punctatus, Using 'Sterile-Feral' Gene Constructs

Templeton, Christopher (2005-08-15)

Channel catfish, Ictalurus punctatus, embryos were electroporated with a sterile feral 3 (SF3), sterile feral 4 (SF4), glutamate decarboxylase (GAD) or CAB constructs and a blank control. Doxycycline was applied to some ...

Effect of calcium on biofilm development and role of mopB and msrA in virulence of Xylella fastidiosa

Chen, Hongyu (2016-07-27)

Xylella fastidiosa is the causal agent of many diseases on economically important plants. Pierce’s disease of grape (PD) and citrus variegated chlorosis (CVC) are among the most important diseases caused by X. fastidiosa. ...

Effects of desiccation practices and ploidy on Vibrio spp. abundances of cultured oysters, Crassostrea virginica

Grodeska, Stephanie (2016-05-05)

The expansion of off-bottom aquaculture of the eastern oyster, Crassostrea virginica, to the Gulf of Mexico accompanied by high temperatures, which are correlated with Vibrio parahaemolyticus and Vibrio vulnificus, has ...

Evaluation of a flow-through depuration system to eliminate the human pathogen Vibrio vulnificus from the eastern oyster (Crassostrea virginica)

Lewis, Matthew (2010-08-03)

Evaluation of a flow-through depuration system to eliminate the human pathogen Vibrio vulnificus was carried out through altering 3 different parameters: salinity, temperature, and flow rate. Oysters were supplied by Auburn ...

Evaluation of Biological Agents for Controlling Enteric Septicemia of Catfish

Carrias, Abel (2011-05-03)

Enteric septicemia of catfish (ESC), caused by the bacterium Edwardsiella ictaluri, is considered the most important bacterial disease of cultured channel catfish Ictalurus punctatus and is estimated to cost the industry ...

Evaluation of the Commercially-Available Probiotic Lymnozyme as an Effective Control of Bacterial Infections in Channel Catfish

Aboagye, Daniel (2008-05-15)

A major problem of commercially-cultured channel catfish (Ictalurus punctatus) in the S. E. United States is disease-related mortality. Probiotics may reduce diseases. A series of pond and challenge studies were conducted ...

Evaluation of the Live Attenuated Vaccine Aquavac Esc and the Effects of a Primary Nursery Phase on the Production of Channel Catfish Fingerling in Earthen Ponds

Carrias, Abel (2005-12-15)

The evaluation of the live attenuated vaccine AQUAVAC ESC® in field conditions as well as the use of a primary nursery phase were studied to determine if better production and survival of fingerlings were obtained. This ...

Genomic Approaches to Characterization of the Innate Immune Response of Catfish to Bacterial Infection

Peatman, Eric (2007-05-15)

Genetic selection for disease resistance encoded in the genomes of blue catfish and channel catfish continues to hold the greatest potential for long-term solutions to aquaculture-based disease outbreaks. Progress towards ...

Genomic Characterization of Expressed Sequence Tags and Gene Expression Profiling of the Three Life-Cycle Stages of Ichthyophthirius multifiliis

Abernathy, Jason (2010-05-05)

The ciliate protozoan Ichthyophthirius multifiliis (Ich) is an important parasite of freshwater fish that causes 'white spot’ disease. Ich is a major contributor of fish mortalities and economic loss to both the ornamental ...
