Throughout 1995, Taura syndrome (TS) persisted as a problem on shrimp farms in the Americas. The geographic range of TS continued to expand and by May, 1995 the disease had reached shrimp farms as far north as South Texas, U.S.A. Investigation into the cause of TS continued with the Taura syndrome virus (TSV). Hasson and co-authors confirmed River's Postulates for TSV, which strengthened the conclusion that TSV is the direct etiology for Taura syndrome. However, some researchers in Ecuador still maintain that TS has a toxic cause. Moreover, Jiminez and co-authors have reported an intracellular bacteria associated with cuticle epidermal lesions of shrimp from some areas. Although survival and production have improved on some farms, effective, specific measures of control for TS remain undefined (or unreported). An impact of TSV on fishery stocks of shrimp has not been documented. Available information indicates that for 1996 and, perhaps beyond, Taura syndrome will continue to be an important issue for shrimp farmers in the Americas.
