The results of epidemiological survey on farm animals of EL Dakhlia and EL Sharkia provinces by using (ELISA) revealed that the incidence percentage of infection with FMDV were not exceed than 37.5% and there is no actual out break during the period of2.

Collection of serum samples (1647) from farm animals for determination of Sceening of the collected 1647 serum samples for the presence of FMDv specific antibodies was be done using ELISA and SNT. The presence of neutralizing antibodies against FMDv inin 321 out of 470 tested sheep serum samples (68.29%),and in 190 out of
