Analysis of repeated compound units in ORF94 of white spot syndrome virus isolated from Litopenaeus vannamei from outbreak and non-outbreak shrimp farms in Sonora, Mexico

White spot syndrome virus (WSSV) is the viral pathogen with the most negative impact on shrimp farming. In Sonora, Litopenaeus vannamei culture has decreased 50% during 2010-2012 due to WSSV outbreaks. The ORF94 has proven to be most useful for the analysis of WSSV variability. Several studies have...
