To assist shrimp pathologists worldwide we are providing here photomicrographs of unique basophilic inclusions that are produced by Wenzhou shrimp virus 8 (WZV8), discovered in 2015 by Li et. al. We designed PCR primers and in situ hybridization probes for detection of WZV8. Subsequent ISH assays with shrimp RT-PCR positive for WZV8 samples indicate unique inclusions described herein as linked to WZV8 in H&E stained tissues. Going back over our previous histological reports and archived slides, we have found the unique WZV8 inclusions in E-cells of normal shrimp samples from several shrimp farming countries in Austral-Asia since at least 2008, and more recently in samples of P. vannamei from the Americas. We urge shrimp pathologists to review their records and specimens for the presence of WZV8 E-cell inclusions described herein to provide data on the global prevalence and impact of WZV8-like infections.

We are pleased to announce that the FAO Reviews of Aquaculture have been published online at the FAO website, including the six Regional Reviews and a Global Synthesis, which were developed and published in conjunction with the Global Conference on Aquaculture Millennium +20 (GCA+20). The publications are linked below. Video presentations of the reviews, including expert panel discussions and question and answer sessions, are also available from the GCA+20 website.
