Saponins are naturally occurring amphiphilic molecules and have been associated with many biological activities. The aim of the present study was to investigate whether soya saponins trigger the onset of soyabean-induced enteritis in Atlantic salmon (Salmo salar L.), and to examine if dietary soya saponins increase the epithelial permeability of the distal intestine in Atlantic salmon. Seven ex...
The regulation of hepatic and intestinal 3-hydroxy-3-methylglutaryl-CoA (HMG-CoA) reductase and acyl-CoA; cholesterol acyltransferase (ACAT) activities by dietary fish oil was examined in the rabbit. Rabbits were fed 10% menhaden oil or menhaden oil plus 1% cholesterol for 14 days. They were compared with animals fed a control diet or one enriched with long-chain saturated fats consisting of 10...
An investigation was conducted to identify the allochthonous microbiota (entire intestine) and the autochthonous microbiota in proximal intestine (PI) and distal intestine (DI) of four species of Indian air-breathing fish (climbing perch; Anabas testudineus, murrel; Channa punctatus, walking catfish; Clarias batrachus and stinging catfish; Heteropneustes fossilis) by PCR based denaturing gradie...
Bioaccumulation of cadmium was assessed in different tissues the benthic fish Solea senegalensis. Juvenile Senegalese soles were simultaneously exposed to cadmium-contaminated diet (Hediste diversicolor) and water during 14 days allowed depurate for another days. Cadmium content measured muscle, gills, liver intestine, with recorded values increasing these this same order. Muscle showed a consi...
The growth performance, immunological status, intestinal morphology and microbiology of tilapia, Oreochromis niloticus, were investigated after dietary administration of the commercial probiotic AquaStar(®) Growout. Tilapia (29.02 ± 0.33 g) were split into five treatments; control (CON), 1.5 g kg(-1) probiotic (PRO-1.5), 3 g kg(-1) probiotic (PRO-3), pulsed probiotic feeding (PRO-PULSE) or an i...
The route of NO(2)(-) uptake and subsequent physiological effects were examined in the marine teleost, European flounder (Platichthys flesus), during exposure to 1 mM ambient NO(2)(-) for up to 11 days. Drinking of seawater resulted in a similar nitrite concentration in the anterior part of the intestine as in the ambient water. The NO(2)(-) concentration decreased along the gastro-intestinal t...
Immunoglobulin M (IgM) is the primary antibody in fish, which transported from epithelial cells into external secretion system by polymeric immunoglobulin receptor (pIgR). In this study, full length of IgM and pIgR complementary DNA sequences leopard coral grouper (Plectropomus leopardus) was characterized, their expression levels under Vibrio harveyi infection were studied. cDNA sequence analy...
Mannose receptor (MR) is a member of pattern-recognition receptors (PRRs), which plays a significant role in immunity responses. Much work on MR has been done in mammals and birds while little in fish. In this report, a MR gene (designated as zfMR) was cloned from zebra fish (Danio rerio), which is an attractive model for the studies of animal diseases. The full-length cDNA of zfMR contains 624...
As an integral part of the resident microbial community of fish intestinal tract, the mycobiota is expected to play important roles in health and disease resistance of the host. The composition of the diverse fungal communities, which colonize the intestine, is greatly influenced by the host, their diet and geographic origin. Studies of fungal communities are rare and the majority of previous s...
