Seasonal variation in the intestinal bacterial flora of hybrid tilapia (Oreochromis niloticus×Oreochromis aureus) cultured in earthen ponds in Saudi Arabia

Haematological changes in Nile tilapia experimentally infected with Enterococcus sp.

“…There are several studies on fish bacteria identification, experimental infection or disease resistance (Azad et al, 2001;Al-Harbi and Uddin, 2004;Cai et al, 2004) but little relates the haematological parameters to bacterial experimental infection. The haematological parameters are an important tool of diagnosis that reveals the state of health of fish (Blaxhall, 1972;Rehulka, 2002;Martins et al, 2004a).…”

Fermentation of Arabinoxylan-Oligosaccharides, Oligofructose and their Monomeric Sugars by Hindgut Bacteria from Siberian Sturgeon and African Catfish in Batch Culture in vitro

“…The resident microbiota in certain fish species, including Siberian sturgeon and African catfish, is a relatively less studied aspect that plays potentially a role in health conservation and nutrition optimization. Based on cultivable isolates, Al-Harbi and Uddin [44] reported that gram-negative bacteria dominate up to 89% of catfish intestine, including Aeromonas hydrophila, Shewanella putrefaciens, Vibrio spp. and Staphylococcus spp.…”

“…Rao [46] indicated that initial concentration of Bifidobacteria in the feces, independent of the dose of the fructo-oligosaccharides, influences the fermentation. The bacterial composition may also be related to fish age or specific individuals, and be influenced by the nutritional status, environmental conditions, and the complexity of the fish digestive system [44,[47][48][49]. However, it has already been shown in the simulator of human intestinal microbial ecosystem, that AXOS supplementation can affect fermentation activity without significantly impacting the total microbial community [50].…”

Evaluation of probiotic strain Bacillus subtilis C-3102 as a feed supplement for koi carp (Cyprinus carpio)

“…The intestinal bacterial flora of hybrid tilapia cultured in earthen ponds has been reported to vary with seasonal changes: Al-Harbi & Uddin [25] reported that Pseudomonas spp. were found only in winter while other bacteria (e.g.…”
