Zebrafish-based platforms have recently emerged as a useful tool for toxicity testing as they combine the advantages of in vitro and in vivo methodologies. Nevertheless, the capacity to metabolically convert xenobiotics by zebrafish eleuthero embryos is supposedly low. To circumvent this concern, a

The spatiotemporal distribution of fluorescent compounds was examined during 48 h after immersion (10 µM) or microinjection (2 mg/kg) in the pericardial cavity (PC), intraperitoneally (IP) and yolk sac (IY) of 3 dpf zebrafsh eleuthero-embryos. By modelling the fluorescence of whole-body contours

Immersion treatment: zebrafish embryos at the two-cell stage were immersed in Danieau’s medium containing the compound. A compound concentration of 10 µM and DMSO concentration of 0.1% (v/v) in a volume of 5 mL was used per well (6-well-plates). At 72 h, the zebrafish medium containing the compound

The Galleria mellonella assay makes use of larvae of the Greater Wax Moth. G. mellonella larvae are injected with a small amount of microorganisms, and survival can easily be followed for up to 1 week. This allows to compare virulence between different organisms. Alternatively, after injection of

The C. elegans assay can be used to study the virulence of various microorganisms, and can be used to evaluate the antimicrobial effect of drugs or drug candidates. The two main outcome parameters are (i) survival of C. elegans and (ii) microbial load.
