Infected shrimp go through an acute phase in which most mortality is observed.
In the ensuing chronic phase shrimp remain infected but otherwise appear normal. If chronically infected shrimp resume normal functions they should be as likely to survive a stress test as naive shrimp. Therefore we undertook this study to determine if chronically infected shrimp can withstand salinity shock as well as naive shrimp. All shrimp were obtained from the SPF program of the United States Marine Shrimp Farming Program. Chronically infected shrimp were shrimp that had survived a previous TSV laboratory per os challenge.
