E. hepatopenaei (EHP)-infected Penaeus stylirostris were
collected from Brunei in 2006. EHP-infected P. vannamei were
collected in shrimp ponds from Vietnam in 2014 and 2015. A population
of P. vannamei was sent from Thailand to our laboratory at
University of Arizona in 2014 for a quarantine purpose, these
shrimp were later diagnosed with EHP infection by histology, their
hepatopancreas, feces and tank water were sampled for PCR
analyses.
