abstract- lactic acid bacteria are commonly found in the gastrointestinal tract of various endothermic animals and humans, in milk, dairy and seafood products and on some plant surfaces. the aim of this study was to investigate the inhibitory effect of isolated lactic acid bacteria from intestines of narrow-barred spanish mackerel (scomberomorus commerson) on listeria innocua growth. five strai...
the purpose of this experiment was to evaluate the effects of salinity on growth parameters and intestine morphology of the caspian white fish. experiment were used with four treatments include,(freshwater (0ppt), brackish water (5ppt), abrupt transition of fish to the salt water 10ppt: )the fish were transferred from fresh water to salt water immediately) and gradual transition of fish to the ...
Stability of bacterial flora in fish intestine is very important, because the intestine is an important organ for outbreak of microbial infections and other fish diseases especially when the fish have not been vaccinated. The aim of this study was to determine the bacterial flora of intestine in sturgeon juvenile in earthen ponds. The results can be applied to prevent the diseases occurren...
an experiment was conducted on broiler chickens to study the effects of conjugated linoleic acid (cla), fish oil, both at 7% of the diet, or their mixtures at 3.5% of the diet, on the performance, carcass traits and intestinal morphology of broiler chickens. the chicks fed with 7% fish oil or 7% cla diets, were found to have an inferior weight gain in grower and finisher phases, respectively. a...
The present study was carried out to investigate contamination of heavy metals in 19 fish species from the Banan section of Chongqing in the Three gorges, yangtze River. The results showed that the mean concentrations of heavy metals were higher in intestine than muscle, except zinc in upper strata. In the fish inhabiting the upper strata, there were significant differences between mean concent...
In this study, we investigated the characteristics of CCK-producing cells and mucus-secreting goblet cells with respect to stomach fish and stomachless fish of the Gobiidae in order to provide a basis for understanding the digestive physiology. Hairychin goby (Sagamia geneionema), which is stomachless fish, the numbers of mucus-secreting goblet cells is highest in the posterior intestine portio...
A total of 154 samples of marine (n=51) and freshwater fish (n=103) were obtained from fish markets in Elazig Province of eastern Turkey. These samples were tested for Campylobacter, Listeria and Salmonella using culturing and biochemical methods. Campylobacter failed to be detected in any freshwater or marine fish samples. Listeria was detected in 22 and 14 of gill and skin samples from freshw...
ABSTRACT- Lactic acid bacteria are commonly found in the gastrointestinal tract of various endothermic animals and humans, in milk, dairy and seafood products and on some plant surfaces. The aim of this study was to investigate the inhibitory effect of isolated lactic acid bacteria from intestines of narrow-barred Spanish mackerel (Scomberomorus commerson) on Listeria innocua growth. Five strai...
The gut transit rate of ingested feed in fish affects the utilization dietary nutrients; however, influence water temperature, remains underexplored Atlantic salmon (Salmo salar). present study quantified four distinct regions gastrointestinal tract (stomach, pyloric caeca, small and large intestine) post-smolt at two temperatures; 11 20°C, by feeding a diet incorporated with Ballotini beads. A...
In marine fish, high epithelial intestinal HCO₃− secretion generates luminal carbonate precipitates of divalent cations that play a key role in water and ion homeostasis. The present study was designed to expose the putative role for calcium and the calcium-sensing receptor (CaSR) in the regulation of HCO₃− secretion in the intestine of the sea bream (Sparus aurata L.). Effects on t...
