in this research, white spot syndrome virus (wssv) with 105.4ld50.ml-1 inactivated with gamma irradiation at a dose rate of 14-15 kgy.sec-1 was used as a vaccine. three hundred and sixty shrimp of litopenaeus vannamei, medium body weight (mbw) 1.0±0.17g), were prepared and experimentally exposed. they were distributed among four groups, inclusing vaccinated-virus exposed (t1), vaccinated-nonvir...

The present study deals with the oral supplementation with (50, 100 and 150 ?g/ml) synergetic effect of potassium and magnesium chloride on the fat body glycogen, protein, total lipids and haemolymph trehalose, protein of fifth instar larvae of Bombyx mori L (Lepidoptera: Bombycidae). The observed parameters significantly increased in all the treated groups when compared with those of the corre...

1. Physical and chemical parameters were measured in the Japanese oyster Crassostrea gigas to investigate whether the first step of urine formation in the lamellibranchs could be an ultrafiltration and to give a quantitative description. 2. The effective filtration pressure was not constant, but a function of time, oscillating between 317mmH2O and —3-8mmHzO. During the filtration, a separation ...

Decapod crustaceans inhabit aquatic environments that are frequently subjected to changes in oxygen content. The physiological mechanisms that allow them to cope with periodic episodes of hypoxia have been well documented. Most crustaceans exhibit a bradycardia coupled with diversion of haemolymph from digestive organs towards ventral structures. However, all these experiments were conducted on...

background: in this study the haemolymph components of infected and none infected lymnaea gedrosiana with xiphidiocercaria larvae was compared. methods: five hundred fifty lymnaea snails were collected from ilam and mazandaran prov­inces, iran, during 2008-2009. the snails were transported to the lab at tehran university of medi­cal sciences and their cercarial sheddings were studied. haemolmyp...

The safety of Archachatina maginata haemolymph on biochemical and hematological indices of albino rats was investigated. Twelve white albino rats were grouped into 3 (A-C) of 4 animals each. Original Research Article Bashir et al.; JAMPS, 3(3): 122-130, 2015; Article no.JAMPS.2015.033 123 Group A rats serve as control groups and received no treatment, while groups B and C received 2 and 4 ml/kg...

Crustaceans affected by shell disease syndrome display characteristic black-spot lesions in regions of exoskeletal degradation. Vogan et al. [Dis. Aquat. Org. (2001)] have shown that the severity of shell disease in the edible crab, Cancer pagurus, correlates with an increase in haemocoelic bacterial infections and may therefore serve as an external marker for the internal health of the animal....

Disseminated neoplasia (DN) has been detected in cockles from various beds in Galicia (NW Spain). A study was performed to characterise cockle neoplastic cell ultrastructure and to evaluate the effect of this disease at different severity stages on various haemolymph cell parameters. Examination of cockle neoplastic cells with transmission electron microscopy (TEM) showed round shapes and a lac...

Changes in the levels of haemolymph metal ions of two binoltine races of the silkworm, Bombyx mori (NB4D2 and CSR2) and the multivoltine race (Pure Mysore ) was studied at different stages of larval and pupal development. The haemolymph metal ions showed significant changes during different stages of larval development like moult, post-moult, feeding and spinning and pupal stages like pre-pupa,...
