Infectious hypodermal and hematopoietic necrosis virus (IHHNV) and Taura syndrome virus (TSV) in wild shrimp (Farfantepenaeus aztecus Ives, 1891 and Litopenaeus setiferus Linnaeus, 1767) of La Laguna Madre, Gulf of Mexico

Abstract

The occurrence of infectious hypodermal and hematopoietic necrosis virus (IHHNV) and Taura syndrome virus (TSV) in wild shrimp Litopenaeus setiferus (white shrimp) and Farfantepenaeus aztecus (brown shrimp) captured from the estuary of La Pesca in La Laguna Madre Tamaulipas, Mexico, are reported. This study was performed for histopathology and amplification of nucleic acids. The prevalence of TSV was 6.6\% (12/180) and 4.4\% for IHHNV (8/180). Most cases were observed from November to March (15/180). The presence of these viruses in wild shrimp from the La Laguna Madre, alerts about the risk that are having the wild populations and the shrimp farms that are contiguous with the Gulf of Mexico, so it is suggested to establish a program of sanitary monitoring and to verify the impact of both viruses in the near shrimp farms of the La Laguna Madre.
