Abstract
It is clear that the study of parasitic fauna of the amphibian parasites has paid with a little attraction from the parasitologists in Egypt except some studies on the predominant parasites species such as nematodes, digeneans or some flagellates in blood. The present thesis is considered to be the first one which deals with the study of different groups of the amphibian parasites in North of Egypt and specially in Damietta governorate. Ten adult parasite species were found to be infected the maculated toad, Bufo regular is that collected from Damietta governorate. These parasites species belong to five different groups; protozoans, digeneans, cestodes, nematodes and acanthocephalans. Four of them were found to be belong to Protozoa, two of them belong to Digenea, one of them belongs to Cestoda, two of them belong to Nematoda and one of them belongs to Acanthocephala. These parasites species are mainly infected the digestive system of B. regular is which was collected from two different localities; the first location is semi-dried while the location was aquous. General survey, morphological and anatomical studies on these ten parasite species were done in the present study. Study of the general survey in the present thesis has revealed that the general prevalence of infection with the different groups of the parasites infecting the maculated toad, B. regular is was 92.69% and the mean intensity of infection was 700.79 ± 131 individuals/infected toad. The infected toads had high infection with protozoans and nematodes. The terrestrial toads that collected from location I had high prevelancc of infection with nematodes, cestodes and acanthocephalans and had high mean intensity of infection with nematodes, cestodes and most of protozoans.
