Probiotics, lactic acid bacteria and bacilli: interesting supplementation for aquaculture
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-05)
Probiotics administration in aquafeed is known to increase feed consumption and absorption due to their capacity to release a wide range of digestive enzymes and nutrients which can participate in digestion process and feed utilization, along with the absorption of diet components led to an increase in host’s health and well‐being. Furthermore, probiotics improve gut maturation, prevention of ...
Histological and bacteriological changes in intestine of beluga (Huso huso) following ex vivo exposure to bacterial strains
(Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
In the present study the intestinal sac method (ex vivo) was used to evaluate the interactions between lactic acid bacteria and staphylococci in the gastrointestinal (GI) tract of beluga (Huso huso). The distal intestine (DI) of beluga was exposed ex vivo to Staphylococcus aureus, Leuconostoc mesenteroides and Lactobacillus plantarum. Histological changes following bacterial exposure were assessed ...
Anti-Infective Effect of Adhesive Probiotic Lactobacillus in Fish is Correlated with Their Spatial Distribution in the Intestinal Tissue
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-10-16)
In this study, we tested the distribution of 49 Lactobacillus strains in the mucus and mucosa of the intestine tissue of zebrafish. We observed a progressive change in the spatial distribution of Lactobacillus strains, and suggested a division of the strains into three classes: mucus type (>70% in mucus), mucosa type (>70% in mucosa) and hybrid type (others). The hybrid type strains were more efficient ...
Bacterial Diversity in the Digestive Tracts of Four Indian Air-Breathing Fish Species Investigated by PCR Based Denaturing Gradient Gel Electrophoresis
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-12-02)
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 gradient ...
The influence of weight and gender on intestinal bacterial community of wild largemouth bronze gudgeon (Coreius guichenoti, 1874)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-22)
Background: Largemouth bronze gudgeon (Coreius guichenoti) is of economic importance in China, distributed in upstream regions of the Yangtze River in China. But it has recently dramatically declined and is close to elimination. However, there is little knowing about the character of its intestinal microbiota. This study was conducted to elucidate the intestinal microbiota of wild largemouth bronze ...
Extracellular tannase-producing bacteria detected in the digestive tracts of freshwater fishes (Actinopterygii: Cyprinidae and Cichlidae)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016)
Background. Although, presence of tannase-producing and/or tannin tolerant gut bacteria has been documented
in ruminants and non-ruminant herbivores, the topic is rarely addressed in fi sh. The present study aimed at
enumeration of autochthonous tannase-producing bacteria in the gut of freshwater teleosts. <p>
Materials and methods. This study covered seven freshwater teleost fi sh species: rohu, ...
Effects of dietary Lactobacillus plantarum and AHL lactonase on the control of Aeromonas hydrophila infection in tilapia
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-04-20)
This study addressed the effects of dietary Lactobacillus plantarum or/and N-acylated homoserine lactonase (AHL lactonase) on controlling Aeromonas hydrophila infection in juvenile hybrid tilapia (Oreochromis niloticus♀ × O. aureus ♂). Fish were fed Lb. plantarum subsp. plantarum strain JCM1149 (108 CFU/g feed) or/and AHL lactonase AIO6 (4 U/g) and were exposed to a chronic challenge of A. hydrophila ...
Analysis of bacterial diversity in the intestine of grass carp (Ctenopharyngodon idellus) based on 16S rDNA gene sequences
(Journal article; Tidsskriftartikkel; Peer reviewed, 2010)
Do stocking densities affect the gut microbiota of gibel carp (Carassius auratus gibelio) cultured in ponds?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
The aim of the present study was to evaluate the intestinal microbial communities of gibel carp (Carassius auratus gibelio) cultivated in two beach ponds at different stocking densities. The two ponds were both ~3.33 hm2 in acreage and ~1.5 m in depth. The stocking densities included one intensive with 2 fish m–3 while the other treated as semi-intensive with 1 fish m–3. The gut microbiota (both ...
Effects of dietary soybean meal, inulin and oxytetracycline on gastrointestinal histological characteristics, distal intestine cell proliferation and intestinal microbiota in Atlantic salmon (Salmo salar L.)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2007)
Soyabean meal (SBM)-induced enteritis in the distal intestine of the teleost Atlantic salmon (Salmo salar L.) and other salmonids may be considered
a model for diet-related mucosal disorders in other animals and man. The role of the intestinal microbiota in its pathogenesis was explored.
Compared to diets containing fishmeal (FM) as the sole protein source, responses to extracted SBM or the prebiotic ...
