The present study was performed to identify the tail rot disease causing bacterium in marine ornamental fish, Amphiprion sebae. Bacteria were isolated from infected immune organs and region of A. Five different bacterial isolates (S1-S5) with shape, size colour chosen for infection study. strains individually challenged sebae at a constant dose 1 × 107 CFU/fish. virulent strain found be S-3, which showed maximum reproducing ability by typical mortality. Furthermore, S-3 identified as Vibrio...
leaf extract of A. marina was tested on the growth clinically isolated multi-drug resistant Staphylococcus aureus and its bioactive compounds were attempted. Clinical strain aureus, from sputum, pus blood different patients 22 strains screened for antibiotic susceptibility. Avicennia extracted in solvents antibacterial assay carried out using Kirby-Bauer's disk diffusion method. Crude methanol mangrove loaded a silica gel column eluted with chloroform (9:1 to 1:9) followed by ethyl acetate...
Mosquito larvicidal and repellent activities of phenolic acids Chaetomorpha antennina (Bory) Kuetz. against the third instar larvae Aedes aegypti were investigated. The larval mortality was observed after 24 h exposure. Results mosquito tests revealed that insoluble bound soluble conjugated acid fractions C. had an excellent inhibitory effect A. its LC50 values 23.4 44.6 μg ml−1, respectively. repellency assay antennina, at 10 cm−2 concentration gave 100% protection up to 120 min. results...
Increasing industrial activity causes the release of chemical compounds into aquatic habitats, including toxic heavy metals like cadmium and medications ketoprofen, posing considerable ecological concerns. Although previous studies have shown that ketoprofen individually cause cognitive impairment, there is a lack information on combined neurological effects two substances. We investigated consequences persistent exposure in presence adult zebrafish, providing an essential model for...
To screen the anti-fungal effects and find out active metabolites from sponge, Sigmadocia carnosa (S. carnosa) against four dermatophytic fungi.The methanol, ethyl acetate acetone extract of marine S. was examined Trichophyton mentagrophytes (T. mentagrophytes), rubrum rubrum), Epidermophyton floccosum (E. floccosum) Microsporum gypseum (M. gypseum) qualitative analysed to molecules.The methanol sponge expressed significant activity than acetone. The minimum inhibitory concentration (MIC)...
To screen inhibitory activity of pigments extracted from two sea-anemones, Heteractis magnifica (H. magnifica) and Stichodactyla haddoni (S. haddoni) against 10 aquatic human bacterial pathogens. Crude pigment were by using acetone solvent the extracts fractionated into 7 for H. 5 S. silica gel column chromatography also tested antibacterial Agar welldiffusion method. The 3rd fraction 2nd displayed higher eight pathogens seven showed than crude other fractions haddoni. Thus sea-anemone is...
The efficacy of supplementation diet with 0, 2.5, 5, and 10 g kg-1 Excoecaria agallocha aqueous leaf extract on innate immune response, survival, disease resistance was reported in clownfish, Amphiprion sebae against Vibrio alginolyticus. mean weight gain (MWG), specific growth rate (SGR), protein efficiency ratio (PER) did not significantly vary any except 5 weeks 6 8. white blood cell (WBC) level increased diets phagocytic activity, alternate complement lysozyme activity 8 whereas the...
