A primary cell culture system was developed for the cells of lymphoid organ tissue of kuruma shrimp, Penaeus japonicus. Minced tissues of lymphoid organs were seeded and incubated at 30 degrees C in medium 199 supplemented with 20% foetal bovine serum, a salt mixture and a lactalbumin hydrolysate (0.1 g/l). Fibroblast-like cells and epithelioid-like cells survived for 54 days. Cells did not survive after trypsin, collagenase or hyaluronidase treatment used for cell dissociation. Mitogens (Con A, PHA-P, Pokeweed) and insulin did not enhance cell proliferation. When penaeid rod-shaped DNA virus (PRDV) was inoculated into the lymphoid organ cell culture, a cytopathic effect was observed within 8 days. On the other hand, large granular haemocytes that were fractionated using a Percoll continuous density gradient were not infected with PRDV in vitro within 10 days, which was the longest period of haemocyte maintenance.
