چکیده انگلیسی
The Penaeus stylirostris densovirus (PstDNV or IHHNV) is the smallest of the known shrimp viruses. It causes severe mortalities in juveniles and sub-adults of the blue shrimp Penaeus stylirostris, while specimens of the white shrimp Penaeus vannamei infected by this virus exhibit reduced growth rates and negative effects on the feed-conversion rate (FCR). To date, no descriptive epidemiological surveys on the prevalence of this virus in shrimp broodstock have been performed. In this study, the prevalence of IHHNV in broodstock of the white shrimp P. vannamei from hatcheries on the northwest of Mexico region was estimated. Prevalence vary across different regions from high (63%) to low (6%) in shrimp broodstock. Several factors, as transport of pathogens by human activities, or the absence or implementation of ineffective biosecurity measures, may explain the observed differences. To the best of our knowledge, the present study is the first to examine the prevalence of IHHNV on broodstock.
