Journal ArticleDOI

Determination of the infectious nature of the agent of acute hepatopancreatic necrosis syndrome affecting penaeid shrimp

TL;DR: AHPNS has a bacterial etiology and Koch's Postulates have been satisfied in laboratory challenge studies with the isolate, which has been identified as a member of the Vibrio harveyi clade, most closely related to V. parahemolyticus.
Journal ArticleDOI

Photorhabdus insect-related (Pir) toxin-like genes in a plasmid of Vibrio parahaemolyticus, the causative agent of acute hepatopancreatic necrosis disease (AHPND) of shrimp.

TL;DR: A duplex PCR diagnostic method, with a detection limit of 10(5) CFU ml(-1), can reliably detect AHPND-causing strains of V. parahaemolyticus and does not cross react with non-pathogenic strains or with other species of Vibrio isolated from shrimp ponds.
Journal ArticleDOI

Development of in situ hybridization and PCR assays for the detection of Enterocytozoon hepatopenaei (EHP), a microsporidian parasite infecting penaeid shrimp.

TL;DR: A PCR assay from this 18S rRNA gene region is shown to be specific to EHP, did not react to 2 other parasitic pathogens, an amoeba and the cotton shrimp disease microsporidium, nor to genomic DNA of various crustaceans including polychaetes, squids, crabs and krill.
Journal ArticleDOI

The Rho signalling pathway mediates the pathogenicity of AHPND-causing V. parahaemolyticus in shrimp.

TL;DR: Results suggest that Rho signalling helps to mediate AHPND pathogenesis in shrimp, and the expression of 376 unique genes was differentially regulated by AHP ND infection.
Journal ArticleDOI

Immunoregulation and Resistance to Aquatic Pathogens with Dietary Nucleotides in Pacific White Shrimp, Litopenaeus vannamei

TL;DR: In this article , the effects of nucleotide supplementation on performance, immune response, and survival when challenged with Vibrio parahaemolyticus, in PWS receiving a diet with FM partially replaced with vegetable protein sources were evaluated.
