Brine shrimp are aquatic crustaceans belonging to a genus of Artemia. This organism is widely used for testing the toxicity of chemicals. In this study, brine shrimp were evaluated as an infection model organism to study bacterial virulence. Artemia nauplii were infected with various pathogenic bacteria, such as Vibrio vulnificus, Pseudomonas aeruginosa, Burkholderia vietnamiensis, Staphylococc...

Although invertebrates lack a true adaptive immune response, the potential to vaccinate Penaeus monodon shrimp against white spot syndrome virus (WSSV) using the WSSV envelope proteins VP19 and VP28 was evaluated. Both structural WSSV proteins were N-terminally fused to the maltose binding protein (MBP) and purified after expression in bacteria. Shrimp were vaccinated by intramuscular injection...

There are about 100 penaeid shrimp species in China’s coastal waters, of which a dozen Penaeus spp. and Metapenaeus spp. have commercial value (Liu 1989a). The main species cultured in China are Penaeus chinensis, P. monodon, P. japonicus, P. merguinsis and P. penicillatus. Chinese shrimp farms are distributed along almost 18,000 km of coastline from Hainan Province in the tropics to Liaoning P...

BACKGROUND Seawater and freshwater shrimp are some of the most common causes of food allergy among children in Thailand. Tropomyosin has been reported as a major allergen for shrimp allergic populations around the world. Despite a high number of shrimp-allergic Thai children, however, it is unknown whether shrimp tropomyosin is a major cause of allergic reactions. OBJECTIVES To clone and char...

Heavy metals are among the most dangerous substances that cause pollution and accumulation in nature. The bio-sensitive way to decompose these pollutants is through adsorption studies with biopolymers. In this study, chitosan, one of common cost-effective biopolymers, was produced be employed aluminum lead, which have proven negative effects on living organisms. production stages shrimp crab sh...

In this study, we discovered that shrimp miR-100 was up-regulated at 24 h after WSSV or Vibrio alginolyticus infection, confirming its participation in the innate immune system of shrimp. The anti-miRNA oligonucleotide (AMO-miR-100) was applied to inhibit the expression of miR-100. After AMO-miR-100 treatment, the shrimp was challenged with WSSV or V. alginolyticus. The knockdown of miR-100 exp...

AIMS To investigate the antimicrobial spectrum of Lactococcus piscium CNCM I-4031 and its protective effect in cooked and peeled shrimp against Brochothrix thermosphacta. METHODS AND RESULTS Sixteen pathogenic and spoiling bacteria were inhibited in Elliker, but not in shrimp juice agar plates. In shrimp packed under modified atmosphere and stored at 8 degrees C, B. thermosphacta (10(3) CFU g...

BACKGROUND Enterocytozoon hepatopenaei (EHP) causes hepatopancreatic microsporidiosis (HPM) in shrimp. It is probably endemic in Australasia and was first characterized and named from the giant or black tiger shrimp Penaeus monodon from Thailand in 2009. Later, it was also found to infect exotic Penaeus vannamei imported for cultivation in Asia. HPM is not normally associated with shrimp mortal...

White-spot syndrome virus (WSSV) is a devastating, infectious virus affecting shrimp. Although sensitive techniques involving PCR have been developed to assist farmers in screening shrimp (brood stock) for WSSV prior to stocking ponds, such practices have not yet been applied in Korea. Despite the rationality of implementing screening, there has been some doubt as to whether the stocking of WSS...

In this study, the toxicity of endosulfan sulfate, the primary degradation product of the insecticide endosulfan, was determined in three life stages of the grass shrimp (Palaemonetes pugio). After 96 h exposure to endosulfan sulfate, the grass shrimp adult LC50 was 0.86 microg/L (95% CI 0.56-1.31), the grass shrimp larvae LC50 was 1.64 microg/L (95% CI 1.09-2.47) and the grass shrimp embryo LC...
