The effect of a practical plant protein-based diet containing vegetable oils (VO) as the major lipid source on the mucosal carbohydrate pattern of the intestine was studied in gilthead sea bream Sparus aurata challenged with the myxosporean parasite Enteromyxum leei. Fish fed for 9 mo either a fish oil (FO) diet or a blend of VO at 66% of replacement (66VO diet) were exposed to parasite-contami...

Oxynticopeptic cells of fish stomach are thought to secrete less acid than the specialized parietal cells of mammalian stomach. Gastric acidity, however, has not been directly compared between fish and mammals. We therefore fed rainbow trout and rats the same meal, and found that the lowest postprandial pH of trout stomach was 2.7, which was only transiently sustained for 1 h, whereas that of r...

This research examined the bacterial loads in intestine, skin and gills of cultured Clarias gariepinus some selected private farms at Eleme, Emohua, Ikwerre, Obio/Akpor Port Harcourt Local Government Areas Rivers State, Nigeria. Determination species characterization fish parts was done using standard microbiological procedures. Results assay showed high count gill, gut from different locations...

The toxicity of cypermethrin (a pesticide) on fingerlings African catfish, Clarias gariepinus was investigate with emphasis histopathological effects. juvenile were exposed to 0, 1.0, 2.0, 3.0, 4.0 and 5.0ppb under experimental condition. growth, nutrient utilization feed parameters (Weight gain, Average Daily Weight Gain, Percentage Gain , Specific Growth Rate Feed Intake ,Feed Conversion Rati...

Sturgeon is one of the most important species of the Caspian Sea aquatics. Unfortunately, this species faces the threat of extinction today. This makes specific studies on any type of sturgeons more important than before. Studies like histological studies, radiology, and sonography, all require a complete understanding of the anatomy of this fish. Since pilot studies showed some misconceptions ...

Infectious pancreatic necrosis virus (IPNV) causes high incidence of disease in salmonids during the first period after SW transfer. During this period as well as during periods of stress, cortisol levels increase and indications of a relationship between IPNV susceptibility and cortisol have been suggested. The intestine is an entry route and a target tissue for IPNV displaying severe enteriti...

Multiplex Fluorescence In-Situ Hybridization (M-FISH) is a recently developed chromosome imaging method in which each chromosome is labelled with 5 fluors (dyes) and is also counterstained with DAPI. This paper proposes an automatic pixel by pixel classification algorithm for M-FISH images using a Bayes Classifier. The M-FISH pixel classification was approached as a 25 class 6 feature pattern r...

This paper presents a novel 3D agent-based model of fish collective behaviour based on topological interaction. To the best of our knowledge, it is the first 3D model that implements topological interaction. Despite the fact that the topological interaction was proposed based on the observation of collective behaviour of bird flock [1], simulations show that our model also displays realistic co...

we described a case of lymphoid follicular hyperplasia that arose from the ileum of a 52-year-old woman. her colonoscopy revealed a large mass in the cecum associated with multiple polypoid lesions in the ileum. histologic examination demonstrated severe lymphocytic infiltration and lymphoid follicles with regular germinal centers, without evidence of malignancy. a right hemicolectomy was perfo...
