Pandalus montagui Bacilliform Virus (PmBV)
Unassigned sp. from Family Baculoviridae Bateman KS, Hicks RJ, Stentiford GD (2008) Pandalus montagui Bacilliform Virus (PmBV) in Pink Shrimp (Pandalus montagui) from the Wash, United Kingdom. In prep.
Mortalities unknown as newly emerged disease. No gross signs of infection.
Histological analysis reveals hypertrophied nuclei containing an eosinophilic finely granular matrix within the epithelial cells of hepatopancreatic tubules. Affected nuclei also displayed marginated chromatin with strands of chromatin traversing the nucleoplasm leading to apparent intra-nuclear compartmentalisation. Affected cells appeared singly or in clusters; cells with hypertrophied nuclei were consistently found to be storage or R cells The infection was not observed in regenerating epithelial (E), fibrillar (F) or blister (B) cells.
