    A portion of the genome of yellow head virus (YHV) of penaeid shrimp was cloned and the cDNA fragment (1161 bp) was designated clone 3-27. The fragment was labeled with digoxigenin and hybridized in situ to tissue sections of YHV-infected Penaeus vannamei. Positively reacting tissues included those of the lymphoid organ, cuticular epithelium, and gills. In addition, connective tissue of hepatopancreas, heart, antennal gland, hematopoietic organ, nerve tract, midgut cecum and muscle reacted to the probe. The probe was highly specific since it hybridized only to tissues from YHV-infected shrimp. It did not react to those of uninfected shrimp or shrimp infected with WSSV (white spot syndrome virus), IHHNV (infectious hypodermal and hematopoietic necrosis virus), or TSV (Taura syndrome virus). The clone was sequenced, and primers were synthesized for rapid detection of YHV in hemolymph using RT-PCR (reverse transcription-polymerase chain reaction). The strand that constituted the viral sequence in the cDNA was also determined via RT-PCR and in situ hybridization with a single-stranded RNA (ssRNA) probe.
