Fish intestinal microbiota changes with diet and this effect is of particular interest considering the increasing substitution of fish meal by plant protein sources. The objective of this work was to study the effects of partial substitution of fish meal with lupin and rapeseed meals on gut microbiota of the gilthead sea bream (Sparus aurata) and in goldfish (Carassius auratus). Faecal, gastrointestinal and intestinal contents were characterized by culture-based and molecular methods. Vibrionaceae was high in faeces and in the intestine of sea bream, while a more diverse microbiota was retrieved from the stomach, where Bacillales and Flavobacteriaceae appeared to be influenced by the diet. PCR-DGGE profiles revealed high diversity of the microbiota...

Anatomy and physiology of digestive tract of crustaceans decapods reared in aquaculture
Provedor de dados: 5
Autores: Ceccaldi, H.
The digestive tract of crustacea is complex. It is composed of a shor t oesophagum, a stomach with two bags, and internal wall with appendags specialized in grinding of feeds. These hard mastication pieces represent the gastric mill. Setae, filters included in the stomach structure allow the separation between food particles and liquid compounds. Those one are coming over through filters and more on to the digestive gland tubules or mid gut gland. In this organ, several types of cells play specialized functions: absorption, enzyme secretion, stocking function. Some cells of a new type, with undefined function, may be neurosecretions function, have been described recently. The end of tubules of digestive gland exhibits cells with embryonic characteristics....

Early weaning of marine fish larvae onto microdiets: Constraints and perspectives
Provedor de dados: 5
Autores: Person, L.
Weaning small sized marine fish larvae at first feeding directly onto compound pellets is still difficult, while good results can be obtained when used in combination with live prey or when a prefeeding period on live prey is provided up to a size of about 2-3 mg. Microdiets are generally well ingested as their acceptability and visual detection may be improved using feeding activators and increasing good perception contrast. In theory, food may be processed to have a correct nutritional balance, selection of high digestible components is very important as larval digestive system is not fully functional during the first 2 or 3 weeks of life.

Localization of Sugar Residues in the Stomach of Three Species of Monkeys (Tupaiidae glis, Nycticebus cocang and Callithrix jacchus) by Lectin Histochemistry
Provedor de dados: 77
Autores: Fayed,Masoud Hassan; Elnasharty,Mohamed; Shoaib,Mahmoud.
The stomach of three species of non-human primates was investigated by lectin histochemistry to clarify the staining affinity and distribution patterns of their sugar residues. All gastric regions, with little differences between the deep and superficial parts of the same region, were rich in. in N-acetylglucosamine and/or neuraminic acid. Although, the superficial regions of the gastric mucosa were scanty in N-acetylgalactosamine, a- D-glucose and a -D-mannose, the deep parts of the gastric mucosa were rich in these sugars. In conclusion, there is a difference among the mucosubstances of surface and foveolar mucous cells, mucous neck cells, and gastric gland cells. This indicates heterogeneous composition of gastric mucus, or mucus molecules with...

Provedor de dados: 77
Autores: Al-Tikriti,Mohammed S; Khamas,Wael; Chebolu,Seetha; Darmani,Nissar A.
Serotonin is an important neurotransmitter in the central (CNS) and peripheral (PNS) nervous systems. It is involved in a variety of physiological processes both in the gut and in the CNS. The present study examined the distribution of serotonin containing enterochromaffin cells in the gastrointestinal tract (GIT) of a vomit competent species, the least shrew. These cells were easily recognized by their globular granules stained with the H&amp;E and serotonin immune-positive stain. The immunoreactive enterochromaffin cells (IERCs) were mainly confined to the basal portion of the glandular epithelium and were distributed throughout the shrew stomach, small and large intestine. None was found to be associated with the mucosal epithelial lining. Moreover,...

Sexual Dimorphism in Histological Structure of Normal Rat Stomach
Provedor de dados: 77
Autores: Zhu,Lei; Wang,Jian Lin.
Fifty male and fifty female Spargue-Dawley rats were randomly chosen and used to study the sexual dimorphisms of stomachic histological structures. The rat stomach consisted of the nonglandular part and the glandular part. The gender differences of the nonglandular part existed in the thicknesses of the stratified squamous epithelium and the longitudinal muscle. These findings revealed that the male rat stomach may storage more foods than the female. The gastric glands occupied all the lamina propria in the glandular part. The thicknesses of the gastric glands of the female and male rat were 525.0 ± 95.9 µm and 472.0 ± 158.7 µm respectively, and the difference was very significant (p&lt;0.01). The gastric glands could be divided to two layers in the HE...

Diagnosing and treating stomach diseases requires as many of the related anatomy details as possible. The objective of this study based on the sectioned images of cadaver was to offer interested clinicians anatomical knowledge about the stomach and its neighbors from the new viewpoint. For the raw data, sectioned images of a male cadaver without stomach pathology were used. By manual segmentation and automatic interpolation, a high-quality volume model of the stomach was reconstructed. The model was continuously peeled and piled to synthetically reveal the inside and outside of the stomach. The anterior, posterior, right, and left views of the models were compared with a chosen sectioned image. The numerous stomach images were then put into user-friendly...

Spring blooms of the toxic dinoflagellate Alexandrium tamarense in the Argentine sea produce shellfish toxicity through the parallytic shellfish poison (PSP)accumulation. The trace PSP content in the mackerel Scomber japonicus liver was previously demonstrated in the Buenos Aires province coastal region (Carreto et al, 1993a),and a certain capability to accumulate the toxins was suggested.However, it was up to spring 1993 when a great number of PSP intoxicated mackerels where detected for the first time in a wideshelf area off the Buenos Aires province. This area, known as 'El Rincón' (39°00'-40°30'S), has become a growing importance mackerel fishing ground during the last few years. A high PSP concentration was determined in those mackerels, being the...

Foals were divided into four age groups of 15 animals as follows: 1 to 30 days, 31 to 60 days, 61 to 90 days and 91 to 120 days. The prevalence of gastric lesions was 43.3%. Foals aged 61 to ninety days were the most affected (nine of 15). There were no significant differences between ages. Squamous epithelial exfoliation was observed in nine foals (60%) less than thirty days, in six (40%) between 31 to sixty days and only in two foals...

Primary gastric non-Hodgkin's lymphoma (NHL) is a co-morbidity that can be observed during the clinical course of acquired immunodeficiency syndrome (AIDS). We evaluated the prevalence, clinical-evolutive aspects and form of endoscopic presentation of primary gastric NHL associated with AIDS. Two hundred and forty-three HIV patients were submitted to upper digestive endoscopy, with evaluation of clinical, endoscopic and histological data. A CD4 count was made by flow cytometry and viral load was determined in a branched-DNA assay. Six cases (five men; mean age: 37 years; range: 29-46 years) of primary gastric NHL were detected. The median CD4 count was 140 cells/mm³ and the median viral load was 40,313 copies/mL. Upper digestive endoscopy revealed polypoid...

Gastropexy techniques are performed aiming to adhere permanently the stomach to the abdomen, being this one of the most common indications for prevention and treatment of gastric dilatation-volvulus (GDV). The only accepted method for the prevention of GDV is the prophylactic gastropexy, and the laparoscopic-assisted procedure is quick and easy to perform. It is aimed to report the association of laparoscopic-assisted prophylactic gastropexyand elective ovariohysterectomy (OVH) in a two years old Great dane bitch using the two-portals access, when it was observed rapid and complete recovery. It is concluded that the two portals laparoscopic-assisted prophylactic gastropexy is feasible and safe in dogs, when combined with elective OVH. It makes the...
