Antihelimentic effect of scorpion venom against isolated from in Egypt.

family has a genetic and morphological variability between species affecting rodents, but it is considerably hard to morphologically diagnose species within the genus of and the individuals of these species are identified according to their host, as it is known that . is strictly host-specific. However, some species lack host specificity. So, it is necessary to use molecular data in order to well identify the spp. in Egyptian rodents. The host examined in the current research is and the molecularly identified species from its cecum is . In addition, was subjected to treatment with Crude Venom as a model of natural alternative treatment for gastrointestinal nematodes that increasingly develop anthelmintic drug resistance. The changes in were monitored using scanning electron microscopy, Crude Venom made a significant ultrastructural surface changes in , including marked cuticular sloughing, disintegrated bacillary glands, bursting of vulva and edema of anal region. This study was done for closer identification of . infecting rodents in Egypt and evaluating the efficacy of Crude Venom .
