The virucidal effect of pH and salinity on Penaeus monodon baculovirus (MBV) was investigated by water borne inoculated methods exposing PL12 Penaeus semisulcatus for 10 hours and observing for 10 days at temperature 28- 30°C. For this purpose, one thousand virus free PL12 of P. semisulcatus were divided into five groups and each group placed in a 10 L plastic basin containing chlorine-treated ...

The lack of a standardised system for the isolation, identification and purification of prawn viruses, is a major obstacle to the control of viruses in penaeid aquaculture. To date, spontaneous and induced transformation of somatic penaeid cells has failed. Hybrid cells with the aim of supporting the growth of penaeid viruses were created using polyethylene glycol (PEG)-mediated fusion with two...

Three shrimps population (Penaeus semesulacatus, Penaeus japonicus,Meta Penaeus monoceros) were investigated for determination of the genetic structure by using (PCR-RAPD) and SDS-PAGE. The results obtained from RAPD technique showed the same percentages of similarity (100%) within the three studied population. On the other hand, the degrees of similarity detected by SDSPAGE were 90%, 87% and 8...

We describe a duplex real-time PCR assay using TaqMan probes for the simultaneous detection of monodon baculovirus (MBV) and hepatopancreatic parvovirus (HPV). Both MBV and HPV are shrimp enteric viruses that infect intestinal and hepatopancreatic epithelial cells. Both viruses can cause significant mortalities and depressed growth in infected larval, postlarval, and early juvenile stages of sh...

In Penaeus indicus neuroendocrine organs plays an important role in the growth and reproduction. In Penaeus indicus four different types of neurosecretory cells such as A cell, B cell, C cell, D cell were identified. The Eyestalk of Penaeus indicus shows many neurosecretory cells, but the Brain and Thoracic ganglion shows only few neurosecretory cells. After the unilateral Eyestalk ablation the...

Saltatory impulse conduction in invertebrates is rare and has only been found in a few giant nerve fibres, such as the pairs of medial giant fibres with a compact multilayered myelin sheath found in shrimps (Penaeus chinensis and Penaeus japonicus) and the median giant fibre with a loose multilayered myelin sheath found in the earthworm Lumbricus terrestris. Small regions of these nerve fibres ...
