White spot syndrome virus (WSSV) in Litopenaeus vannamei captured from the Gulf of California near an area of extensive aquaculture activity.
For the shrimp farming industry of Mexico, disease outbreaks caused by white spot syndrome virus (WSSV) are relatively recent. Efforts to control the virus are assisted by monitoring for its prevalence in aquaculture systems, but few attempts have been made to search for it in carriers from coastal waters. To search for WSSV carriers in the Gulf of California, we made surveys off the coast of Sinaloa, Mexico, in March 2001, November 2001, and September 2003 using polymerase chain reaction (PCR) assays and histopathology. WSSV-positive shrimp were detected only in November 2001, after hurricane Julliete. This suggested possible dispersal of WSSV to the marine environment from infected shrimp farms.
