The incidence of white spot disease in farmed Penaeus indicus in Busheher region was evaluated by analyzing 200 shrimp individuals between June and September, 2005. The samples were examined for clinical sign including observation of white spots on the cuticle and tissue. Samples were processed using polymerase chain reaction (Nested-PCR) test. The results showed that 24% of the samples examine...

Recent studies have shown that the ubiquitin proteasome pathway (UPP) is closely related to immune defense. We have identified a ubiquitin-conjugating enzyme E2 from the Chinese white shrimp Fenneropenaeus chinensis (FcUbc). Injection of recombinant FcUbc protein (rFcUbc) reduced the mortality of shrimp infected with White Spot Syndrome Virus (WSSV) and inhibited replication of WSSV. rFcUbc, bu...

This paper describes a new bacterial white spot syndrome (BWSS) in cultured tiger shrimp Penaeus monodon. The affected shrimp showed white spots similar to those caused by white spot syndrome virus (WSSV), but the shrimp remained active and grew normally without significant mortalities. The study revealed no evidence of WSSV infection using electron microscopy, histopathology and nested polymer...

The banded coral shrimp, Stenopus hispidus (Crustacea: Decapoda: Stenopodidea) is a popular marine ornamental species with a circumtropical distribution. The planktonic larval stage lasts ∼120-253 days, indicating considerable dispersal potential, but few studies have investigated genetic connectivity on a global scale in marine invertebrates. To resolve patterns of divergence and phylogeograph...
