An evaluation of implanted male Onchocerca gibsoni in mice as a screen for macrofilaricides against Onchocerca volvulus. Tropical medicine and parasitology : official organ of Deutsche Tropenmedizinische Gesellschaft and of Deutsche Gesellschaft fur Technische Zusammenarbeit (GTZ), 1988, Volume: 39 Suppl 4 An in vivo drug screen for identifying new compounds with activity against Onchocerca macrofilariae was developed using male Onchocerca gibsoni implanted subcutaneously in outbred mice. There were several similarities (Mel W, CGP 20376, CGP 6140, levamisole) and two differences (suramin, furapyrimidone) between levels of drug efficacy in this model and activity against natural infections of O. gibsoni and O. volvulus. There was considerable variation in the mouse reaction. This mouse model is a potentially useful primary screen for macrofilaricidal drugs against Onchocerca.

In vitro drug screening in isolated male Onchocerca gibsoni using motility suppression. Tropical medicine and parasitology : official organ of Deutsche Tropenmedizinische Gesellschaft and of Deutsche Gesellschaft fur Technische Zusammenarbeit (GTZ), 1987, Volume: 38, Issue:2 A primary in vitro screen was developed to screen for drug activity against isolated Onchocerca gibsoni. The assay estimates variation in motility through the use of a motility meter. Of the seven compounds tested in the screen; ivermectin, CGP 6140, CGP20376, Mel W and furapyrimidone gave MI50 concentrations (the concentration at which the motility was reduced to 50% of the control value at 72 hours) below 10(-4) M, whereas suramin gave variable results depending on the varying susceptibility of individual worms and levamisole at 10(-4) M had no significant effect on the worms. The effects of these drugs were not reversible as removal of the worms into drug-free medium caused no increase in motility. Thus the reduction in motility is regarded as indicating significant metabolic damage. The results compared favourably with reported in vivo tertiary screens for activity against Onchocerca species. This is a quantitative, inexpensive and reproducible method for assessing the effectiveness of drugs against Onchocerca and could be included into the primary screens for activity against filarial worms.
