in this study brown algae, sargassum glaucescens and that found plenteously in persian gulf and bushehr coast, were collected and hot water extracts of them were lyophilized. f. indicus (11.32±1.20 g), after two weeks adaptation in shoghab research station dependent to iran shrimp research center, isrc, were immersed in seawater (39 ppt and 25±1 c○) containing hot-water extract of brown algae, ...

The total haemocyte count (THC), differential haemocyte count (DHC), phenoloxidase activity, respiratory bursts (release of superoxide anion), superoxide dismutase activity, phagocytic activity and clearance efficiency to the pathogen Photobacterium damsela were measured when tiger shrimp Penaeus monodon (13.5+/-1.5 g) were individually injected with saline or dopamine at 10(-8), 10(-7), or 10(...

The total haemocyte count (THC), differential haemocyte count (DHC), phenoloxidase activity, respiratory burst (release of superoxide anion), superoxide dismutase activity, phagocytic activity and clearance efficiency to the pathogen Vibrio alginolyticus were measured when the white shrimp Litopenaeus vannamei (9.4-11.3 g) were injected individually with sodium alginate at 10, 20 or 50 microg g...

The Outer Membrane Protein (OMP) of Vibrio alginolyticus cell wall was administered intramuscularly (IM) to the tiger shrimp (Penaeus monodon Fab.) at 10, 20, 30 μg/kg bw. After 14 days infection, the tiger shrimps were challenged with 10(7) bacterial density of Vibrio harveyi for 24 hours. The total haemocyte count (THC), differential haemocyte count (DHC) and amount of total protein plasma (T...

Abstract This study aims to determine the effectiveness of supplementation sodium (Na) alginate Sargassum sp. from Lampung waters enhance non-specific immune response and resistence Pacific white shrimp ( Litopenaeus vannamei ) against spot disease. used a completely randomized design with 3 treatments, namely feeding without (A) or control, dietary Na at dose 2.0 (B), 4.0 g kg −1 feed (C), eac...

The occurrence of brown ring disease (BRD) in farmed Manila clams Ruditapes philippinarum is seasonal. Development of the disease is believed to require the presence of the infective agent Vibrio tapetis and particular environmental conditions. This paper studies the effect of salinity (20 to 40 per thousand) on measurable immune parameters of Manila clams, and the progression of BRD in experim...

The immunomodulatory action of superoxide dismutase (SOD) and its possible use as an indicator of immune responses in American white shrimp (Litopenaeus vannamei) were studied. Juvenile shrimp were immersed in aerated beta-glucan and sulfated polysaccharide solutions for 6 h. SOD activity in haemocytes and muscle was quantified to evaluate whether beta-glucan and sulfated polysaccharide induce ...
