Pathogen Characteristics
Top of pageYellow head virus (YHV) is the cause of yellow head disease in penaeid shrimp.
YHV forms enveloped, rod-shaped particles 40-50 nm × 150-180 nm (Chantanachookin et al., 1993; Wongteerasupaya et al., 1995). Envelopes are studded with prominent peplomers projecting approximately 11 nm from the surface. Nucleocapsids appear as rods (diameter 20-30 nm) and possess a helical symmetry with a periodicity of 5-7 nm. Virions comprise three structural proteins (nucleoprotein p20 and envelope glycoproteins gp64 and gp116) and a ~26 kb positive-sense single-stranded RNA genome.
'Infection with yellow head virus' is on the list of diseases notifiable to the World Organisation for Animal Health (OIE). For further information on this disease from OIE, see the website: www.oie.int
