摘要: Monolayer cultures were established from ovary, heart, lymphoid tissue and peripheral hemocytes of penaeid shrimps including Penaeus monodon, P. japonicus penicillatus. The most favorable conditions for the culture shrimp cells in vitro was CMRL L-15 media when used within an osmolarity range 620--760 mmol/kg. optimal maintenance temperature 25 °C tissues 28 monodon Among four tested, tissue, or 'Oka organ', superior to other formation confluent cell monolayers. Cell ovary have been subcultured up three times. When heart cultured, a maximum survival 4 days obtained. In contrast, derived maintained alive at least 20 appropriate systems. Neither sheet nor adherence obtained cultivation hepatopancreas using present results study also revealed that extract, muscle extract lobster hemolymph enhanced cultured vitro. organ' monolayer incubated with either white spot disease virus (WSDV) yellow head (YHV), no cytopathic effect (CPE) However, 5--7 after establishment, significant CPE (a few foci) observed monolayers WSDV- YHV-infected Oka tissue. By electron microscopy, virions WSDV YHV nuclei cytoplasm cells. foci developed further increased incubation time.
