Resumo: | 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 &lt;i&gt;&lt;i&gt;Artemia&lt;/i&gt; franciscana&lt;/i&gt; 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 &lt;i&gt;A. franciscana&lt;/i&gt;. To monitor their levels as a function of time, the liquid chromatographic method originally developed for the analysis of &lt;i&gt;A. franciscana&lt;/i&gt; was modified with respect to chromatography, internal standardization, and sample pretreatment. The levels of trimethoprim ranged from 1 to 7 µg/g (sea bass), 1 to 13µg/g (turbot), and 4 to 38 µg/g (white shrimp). The corresponding values for sulfamethoxazole were 0.3 to 4 µg/g (sea bass), 1 to 42 µg/g (turbot), and 4 to 35µg/g (white shrimp). Only the two fish species, unlike the shrimp, metabolized the latter to &lt;i&gt;N&lt;/i&gt;-acetylsulfamethoxazole (concentration range, 1 to 10 µg/g). These data suggest the potential of the bioencapsulation of therapeutic agents in live food as a tool to control infectious diseases in aquaculture. A preliminary challenge test also confirmed the in vivo efficacy of this approach.
