Molecular phylogeny and in situ detection of the etiologic agent of necrotizing hepatopancreatitis in shrimp.
Necrotizing hepatopancreatitis (NHP) is a severe disease of farm-raised Penaeus vannamei that has been associated with mortality losses ranging from 20 to 95%. NHP was first recognized in Texas inExpand

Streptococcus shiloi, the name for an agent causing septicemic infection in fish, is a junior synonym of Streptococcus iniae.
Streptococcus shiloi strains, including the type strain, which were isolated in Israel and the United States, and Streptococcus iniae ATCC 29178(T) (T = type strain) are phenotypically identical (asExpand
