This study was conducted to record the histological features of the gastrointestinal tract of wild Indonesian shortfin eel, Anguilla bicolor bicolor (McClelland, 1844), captured in Peninsular Malaysia. The gastrointestinal tract was segmented into the oesophagus, stomach, and intestine. Then, the oesophagus was divided into five (first to fifth), the stomach into two (cardiac and pyloric), and ...
An experiment was performed to examine the interaction between Zn deficiency and lipid intake in carp. The carp were given a high-lipid diet that was either Zn-deficient (ZD) or Zn-supplemented (ZS), or were pair-fed (PF) the ZS diet to the intake of the ZD group. After 8 weeks the carp were killed and measurements were made of intestinal glucose uptake, levels of DNA, RNA and triacylglycerol, ...
Identification of tetrodotoxin (TTX) and its derivatives produced from a Vibrio strain in the intestine of the puffer fish Fugu vermicularis radiatus was performed by thin-layer chromatography, electrophoresis, high-performance liquid chromatography, and gas chromatography-mass spectrometry, together with a mouse bioassay for toxicity. It was demonstrated that the isolated bacterium produced TT...
This minireview summarizes the present state of knowledge concerning the importance of yeasts in fish gut. Yeasts have been commonly isolated in the gastrointestinal tract, and high population densities were sometimes noted in healthy fish, but the data were quite variable in terms of colony counts and taxonomical diversity. Rhodotorula sp. seemed relatively frequent in both marine and freshwat...
As the intestine is an essential organ for fish osmoregulation, the intestinal hormone guanylins may perform major functions, especially in euryhaline fish such as eels and salmonids. From the intestine of an eel, we identified cDNAs encoding three distinct guanylin-like peptides. Based on the sequence of mature peptide and sites of production, we named them guanylin, uroguanylin, and renoguany...
INTRODUCTION The ingestion of a foreign body is relatively common. However, it rarely results in the perforation of gastrointestinal tract. We herein report an unusual case of malignant lymphoma incidentally diagnosed after the perforation of the small intestine by a fish bone. PRESENTATION OF CASE A 90-year-old woman was admitted to our hospital because of abdominal pain and vomiting. Abdomi...
The intestine of marine fish plays a crucial role in ion homeostasis by selective processing of ingested fluid. Although arginine vasotocin (AVT) is suggested to play a role in ion regulation in fish, its action in the intestine has not been demonstrated. Thus, the present study investigated in vitro the putative role of AVT in intestinal ion transport in the sea bream (Sparus aurata). A cDNA e...
Diplostomum spathaceum is a digenean parasite with an indirect life cycle. Its mature stage lives in gull's intestine, cercariae in snails (Lymnaeidae) liver and metacercariae stage in piscine, amphibian, and mammalian eyes. Notice that penetration of cercariae into skin and eye cause lesions which cause susceptibility to secondary infections, appetite loss due to infections, blurry vision, and...
Despite wide studies of biomonitoring aquatic environment through dynamics host–parasite interaction, bio-indicators to track the influence and accumulation heavy metals on fish are still few. The present study sheds light relation between parasites as it threatens fish’s health and, a consequence, that humans after consumption. Samples Nile tilapia ( Oreochromis niloticus ) were collected in B...
