Cuatro cepas de AHPND identificadas en granjas de camarón de América Latina

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

Four AHPND strains identified on Latin American shrimp farms

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.

Probiotics benefit Pacific white shrimp challenged with AHPND

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

A holistic management approach to EMS

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.

PCR methods characterize AHPND V.p isolates

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.

Limited decomposition enhances PCR detection of AHPND Vibrio in shrimp

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

Genetic variation for resistance to WSS, AHPND in Pacific white shrimp

Selection for disease resistance has been used in breeding farm animals and can be a viable option to deal with white spot syndrome and acute hepatopancreatic necrosis disease in commercial shrimp culture. In trials, heritability for AHPND resistance was low,
