(Springer Nature, 2021-03-24)Diseases are important drivers of population and ecosystem dynamics. This review synthesizes the effects of infectious diseases on the population dynamics of nine species of marine organisms in the Chesapeake Bay. Diseases ... -
Examination of a Culturable Microbial Population from the Gastrointestinal Tract of the Wood-Eating Loricariid Catfish Panaque nigrolineatus
(MDPI, 2013-08-19)Fish play a critical role in nutrient cycling and organic matter flow in aquatic environments. However, little is known about the microbial diversity within the gastrointestinal tracts that may be essential in these ... -
First data on aquaculture of the Tripletail, Lobotes surinamensis, a promising candidate species for U.S. marine aquaculture
(Wiley Online Library, 2021-05-18)The Tripletail, Lobotes surinamensis, is a warm-water pelagic fish that is increasingly targeted by U.S. anglers. The superior quality of Tripletail flesh coupled with the lack of domestic commercial fisheries stimulated ... -
First evaluation of resistance to both a California OsHV-1 variant and a French OsHV-1 microvariant in Pacific oysters
(BioMed Central, 2019-12-12)Background: Variants of the Ostreid herpesvirus 1 (OsHV-1) cause high losses of Pacific oysters globally, including in Tomales Bay, California, USA. A suite of new variants, the OsHV-1 microvariants (μvars), cause very ... -
Genetic and Physiological Characterization of the Antibacterial Activity of Bacillus subtilis subsp. inaquosorum Strain T1 Effective Against pirABVp-Bearing Vibrio parahaemolyticus
(American Society for Microbiology, 2020-08-10)Acute hepatopancreatic necrosis disease (AHPND) is caused by PirAB toxin-producing Vibrio parahaemolyticus and has devastated the global shrimp aquaculture industry. One approach for preventing growth of AHPND-producing ... -
Genetic compensation of triacylglycerol biosynthesis in the green microalga Chlamydomonas reinhardtii
(Wiley, 2022-06-21)Genetic compensation has been proposed to explain phenotypic differences between gene knockouts and knockdowns in several metazoan and plant model systems. With the rapid development of reverse genetic tools such as ... -
Genetic subtyping and phylogenetic analysis of HA and NA from avian influenza virus in wild birds from Peru reveals unique features among circulating strains in America
(PLOS, 2022-06-07)Avian influenza virus (AIV) represents a major concern with productive implications in poultry systems but it is also a zoonotic agent that possesses an intrinsic pandemic risk. AIV is an enveloped, negative-sense and ... -
The glycoprotein, non-virion protein, and polymerase of viral hemorrhagic septicemia virus are not determinants of host-specific virulence in rainbow trout
(BioMed Central Ltd, 2019-03-07)Background Viral hemorrhagic septicemia virus (VHSV), a fish rhabdovirus belonging to the Novirhabdovirus genus, causes severe disease and mortality in many marine and freshwater fish species worldwide. VHSV isolates ... -
Gnrh2 maintains reproduction in fasting zebrafish through dynamic neuronal projection changes and regulation of gonadotropin synthesis, oogenesis, and reproductive behaviors
(Springer Nature, 2021-03-23)Restricted food intake, either from lack of food sources or endogenous fasting, during reproductive periods is a widespread phenomenon across the animal kingdom. Considering previous studies show the canonical upstream ... -
Identification and characterization of the pckA gene from Staphylococcus aureus
(American Society for Microbiology, 1996-06)The Staphylococcus aureus pckA gene was identified and characterized. A pckA mutant lacked detectable phosphoenolpyruvate carboxykinase activity and grew poorly in the absence of glucose. Both enzymatic activity and pckA ... -
Induced Spawning of F1 Wreckfish (Hapuku) ¯ Polyprion oxygeneios Using a Synthetic Agonist of Gonadotropin-Releasing Hormone
(MDPI, 2019-07-08)Wild-caught hapuku ( ¯ Polyprion oxygeneios) spawn readily in captivity, but although first filial (F1) hapuku complete vitellogenesis, females fail to undergo oocyte maturation and spawn or produce poor quality eggs. ... -
Intensive oyster aquaculture can reduce disease impacts on sympatric wild oysters
(Inter-Research, 2018-12-13)Risks associated with disease spread from fish and shellfish farming have plagued the growth and public perception of aquaculture worldwide. However, by processing nutrients and organic material from the water column, ... -
