Abstract
The formation of spheroid cells in the lymphoid organ of penaeid prawns has been suggested to be associated with infectious diseases either bacterial or viral. In this study, the abundance of lymphoid organ spheroid (LOS) cells, termed spheroid to total tissue (STT) ratio, in association with the moulting stages in Penaeus monodon that were experimentally infected with presumptive gill associated virus (GAV) was investigated. The experimental prawns were divided into 2 groups: A control group and a GAV infected group. The day post-injection was classified in three categories: (1) 1 5 dpi; (2) 6 10 dpi and (3) 11 onward dpi. The results showed that there were no significant effects of days post-injection, moult stages, lunar phase, and the size of the animals on the STT ratio (P>0.05). The relationship between the LOS cells and lunar phase was being masked by the significant interaction between lunar cycle and the treatments (P<0.05). In the control group, the ratio of STT was lowest at the new moon and highest at the full moon. On the other hand, in the infected (GAV) group, the ratio of STT was lowest at first quarter moon and highest at last quarter moon. The STT ratio was significantly higher in infected group than in the control group (P<0.05). In this study, sex also had a significant effect on the spheroid to total tissue ratio of P. monodon (P<0.05).
