Abstract Feeding rainbow trout, Oncorhynchus mykiss (Walbaum), with 1% lupin, Lupinus perennis , mango, Mangifera indica or stinging nettle, Urtica dioica for 14 days led to reductions in mortality after challenge Aeromonas hydrophila . In addition, there was significant enhancement serum bactericidal activity, respiratory burst and lysozyme activity the treatment groups compared controls. Use of lupin mango highest number red blood white cells recipient fish, use nettle leading haematocrit...
The present study evaluated the effects of dietary onion (Allium cepa)powder and its extracts on growth, blood biochemical parameters, non-specific immune parameters potential disease resistance against pathogenic Aeromonas hydrophila infection in Oreochromis niloticus. Fish formulated diets containing powder (1% or 0.5%) alcoholic 0.5%). At end experiment, weight gain specific growth rate were significantly increased than control. Besides, red cells (RBCs) haemoglobin (Hb) showed a...
The fungal extract of Drechslera rostrata and Eurotium tonpholium showed a significant anti-leishmanial activity against Leishmania major; IC50 was 28.8 28.2 μg/mL, respectively. Seven compounds, five from D. (H1-H5) two E. (H6 H7), were isolated identified using different spectroscopic analysis including (1) HNMR, (13) CNMR, Hetero-nuclear multiple bond connectivity (HMBC), Multiple Quantum Correlation (HMQC), EI-MS. compounds are: di-2-ethylhexyl phthalate (1),...
The study aimed to evaluate the effect of dietary inclusions Moringa oleifera on growth, haematology, antioxidant activities, immunity, and protection against Aeromonas hydrophila in Oreochromis niloticus. Diets supplemented with 0.5% or 1% either crude moringa (CM) powder alcoholic extracts (AME) were used. Weight gain (WG), specific growth rate (SGR), haematological parameters (RBCs count, Hb content HCT %) significantly improved (p < 0.05) feeding CM than control fish, meanwhile they...
Using plant extracts as immunostimulants in aquaculture has prove effectiv resisting infectious disease, addition to being safe and inexpensive. The present study is concerned about the prospective mode of action using lesser galangal extract (Alpinia officinarum) encapsulated into amine surface functionalized mesoporous silica nanoparticles (MSN) order elevate immune status rainbow trout (Oncorhynchus mykiss). Fish were randomly divided 6 groups fed for 4 weeks with commercial diets...
Aquatic pollutants are responsible form any alterations in fish health.Our study was designed to examine the efficacy of dietary supplement black mustard seed, Brassica nigra (30% crude and 1% alcoholic extract) on enhancement immunity detoxification response Nile tilapia, Oreochromis niloticus after exposed a hydrocarbon pollutant; Benzo-a-Pyrene (BaP).Fish were divided into 3 groups before being fed for 28 days with seeds,1% extract un-supplemented commercial diet as control.At end...
The virulent clonal populations of Aeromonas spp. are recognized as the etiological agent motile septicemia (MAS) outbreaks in aquaculture. This study aimed to identify isolated from diseased Oreochromis niloticus, evaluate their virulence factors, and assess resistance antimicrobial agents. Species identification was conducted through analysis gyrB genes. Antibiotic phenotypes genotypes (blaTEM, blaCTX-M, aac(6′)-Ib-cr, intI1) were determined. results indicated that 44,4% isolates belonged...
This study investigated the effect of a lemon, onion, and garlic (LOG) juice mixture on Nile tilapia health productivity including; growth performance, feed utilization, body composition, immune status gene expression IGF-1, IGF-2, GH genes. 120 fish were randomly distributed among 12 tanks into four groups before fed with different iso-nitrogenous iso-caloric diets, containing 0%, 0.5%, 1.0%, or 1.5% LOG for 56 days. The results revealed significant improvements in especially specific rate...
