The presence of AHPND-Vibrio parahaemolyticus can be detected both in fecal DNA samples and in the enriched bacterial broth with samples of enrichment broth showing increased sensitivity.
This year’s Aquaculture America in San Antonio, Texas, provided significant learning and networking opportunities. It successfully brought together 14 U.S. aquaculture organizations and more than 1,600 participants from Europe, Asia, Africa and Australia.
Se conocen dos genes de virulencia que codifican una toxina binaria de Photorhabdus relacionada con insectos que causa la enfermedad de necrosis hepatopancreática aguda en camarones. Las patogenicidades de estas cepas de V. campbellii fueron evaluadas mediante infección de laboratorio
Two virulence genes are known to encode a binary photorhabdus insect-related toxin that causes acute hepatopancreatic necrosis disease in shrimp. The pathogenicities of these V. campbellii strains were evaluated through laboratory infection and subsequent histological examination in P. vannamei shrimp.
Un estudio fue llevado a cabo para medir los efectos de probióticos comerciales en camarón blanco del Pacífico en un modelo de desafío a AHPND estandarizado bajo condiciones controladas de laboratorio. Los resultados muestran que los tratamientos de probióticos por
A study was conducted to measure the effects of commercial probiotics on Pacific white shrimp in a standardized AHPND challenge model under controlled laboratory conditions. Results show that the probiotics treatments by themselves have beneficial effects, such as higher survival
Early Mortality Syndrome has devastated farmed shrimp in Asia and Latin America. With better understanding of the pathogen and the development and improvement of novel strategies, shrimp farmers are now able to better manage the disease.
In analyzing the plasmid sequence from the whole genome sequences of AHPND V. parahaemolyticus (V.p) isolates, researchers identified a clear geographical variation within the plasmid, and developed PCR methods to characterize AHPND V.p isolates as either Mexico-type or Southeast Asia-type.
A study confirmed the utility for improved polymerase chain reaction (PCR) detection of the Vibrio bacteria that cause acute hepatopancreatic necrosis disease (AHPND) in asymptomatic shrimp by permitting the shrimp to expire and decompose for several hours prior to preservation
