Accumulation of trimethoprim, sulfamethoxazole, and <i>N</i>-acetylsulfamethoxazole in fish and shrimp fed medicated <i>Artemia franciscana</i> OMA
Chair, M.; Nelis, H.J.; Leger, P.; Sorgeloos, P.; De Leenheer, A.P..
In a previous paper (H.J. Nelis, P. Léger, P. Sorgeloos, and A.P. De Leenheer, Antimicrob. Agents Chemother. 35:2486-2489, 1991) it was reported that two selected antibacterial agents, i.e. trimethoprim and sulfamethoxazole, can be efficiently bioencapsulated in nauplii of the brine shrimp <i><i>Artemia</i> franciscana</i> for administration to fish. This follow-up study showed that larvae of the sea bass and the turbot as well as postlarvae of the white shrimp accumulate the therapeutic agents in high quantities when fed medicated <i>A. franciscana</i>. To monitor their levels as a function of time, the liquid chromatographic method originally developed for the analysis of <i>A. franciscana</i> was modified...

Bioencapsulation of the antibacterial drug sarafloxacin in nauplii of the brine shrimp <i>Artemia franciscana</i> OMA
Dixon, B.A.; Van Poucke, S.; Chair, M.; Dehasque, M.; Nelis, H.J.; Sorgeloos, P.; De Leenheer, A.P..
Nauplii of the brine shrimp <i>Artemia franciscana</i> were enriched with the antibacterial drug sarafloxacin hydrochloride to determine if levels effective against four pathogenetic strains of <i>Vibrio</i> spp. would accumulate in brine shrimp. Three vibrio strains were <i>Vibrio anguillarum</i>; the fourth was <i>V. vulnificus</i>. Concentrations of sarafloxacin ranging from 1 to 40% (weight: volume) were incorporated into the oil phase of Super Selco brine shrimp diets. Enriched nauplii and controls were sampled at 2h interval for 24h. Antibiotic sensitivity testing was evaluated with a modification of the Kirby-Bauer disk diffusion method. A microbiological assay with <i>Escherichia coli</i>...

Enrichment of live food with essential fatty acids and vitamin C: effects on milkfish (<i>Chanos chanos</i>) larval performance OMA
Gapasin, R.S.J.; Bombeo, R.; Lavens, P.; Sorgeloos, P.; Nelis, H.J..
The effects of essential fatty acids (EFA) and vitamin C-enriched live food on growth, survival, resistance to salinity stress and incidence of deformity in milkfish larvae reared in tanks were investigated. Larvae were either fed rotifers cultured on <i>Chlorella</i> sp. and newly hatched <i>Artemia</i> nauplii (control), highly unsaturated fatty acid (HUFA)-enriched rotifers and <i>Artemia</i> nauplii or HUFA + vitamin C-enriched rotifers and <i>Artemia</i> nauplii. Milkfish growth in outdoor nursery ponds was also assessed to compare with growth in indoor tanks. Milkfish fed rotifers/<i>Artemia</i> enriched with HUFA (32-48 mg dry weight, DW) or HUFA + vitamin C (33-45 mg DW) exhibited...

Progress in biomedication using live foods OMA
Robles, R.; Sorgeloos, P.; Van Duffel, H.; Nelis, H.J..
With the intensification of aquaculture production systems, mass mortality of fish and shellfish caused by bacterial infections is not unusual. Chemotherapy (treatment of infection with antimicrobial compounds) and immunoprophylaxis (vaccination and immunostimulation), are the common methods applied to treat bacterial infections. In search of an efficient and cost-effective delivery route for antimicrobial agents and/or immuno-prophylactics to treat fish and shrimp larvae, the use of live prey organisms bioencapsulated with drugs has been explored. This article provides an update on the use of the bioencapsulation technique in aquaculture.

Solid-phase extraction of ascorbic acid 2-sulfate from cysts of the brine shrimp <i>Artemia fransiscana</i> OMA
Nelis, H.J.; Merchie, G.; Lavens, P.; Sorgeloos, P.; De Leenheer, A.P..
Two producers are described for the solid-phase extraction of ascorbic acid 2-sulfate from cysts of the brine shrimp <i>Artemia</i> . The first one is based on reversed-phase ion pair extraction on an octadecylsilica cartridge using tetrabutylammonium as the counterion, followed by elution with methanol. In the second procedure ascorbic acid 2-sulfate is retained on a DEAE silica cartridge and eluted with 0.1M sodium salicylate. Both approaches were used as part of a quantitative reversed-phase ion pair liquid chromatographic method with detection at 254nm. The anion exchange extraction procedure is superior to its ion pair counterpart in terms of recovery (88.7±3,5% versus 63.0±12.7%), reproducibility (CVs of 3.6-7.7% versus 6.3-18.7%), and...
