''Proceedings of the Annual Convention of the AAEP'', 48:181-185.</ref> The vaccine proved to be ineffective in the prevention of EPM and has since been removed from the market (Furr) . There is evidence to suggest that the antiprotozoal, ponazuril, may be useful prophylactically to reduce the incidence and severity of clinical signs (111 in Furr). Implementing such a regime prior to and during stressful events may be beneficial, although the cost is likely to be prohibitive (Furr). |
