Resumo: 	Bovine schistosomiasis, caused by Schistosoma bovis, is a serious veterinary problem in many parts of the worid. The current methods used for the diagnosis of the disease include clinical signs, pathological lesions, parasitological and serological techniques. As clinical signs and parasitological lesions caused by S. bovis are indistinguishable from those induced by other trematode parasites, confirmation of diagnosis by these methods is unreliable. Parasitological techniques used to demonstrate eggs of the parasite in fecal or tissue samples represent the most accurate method for detection of an active S. bovis infection. The tissue of choice for detection of S. bovis infection is the liver because of the visible macroscopic lesion that can be seen in that organ and the rapid detection of the parasite eggs under the microscope using crush smears. The serological techniques used for diagnosis of the disease do not necessarily identify an active infection. In addition, some of the positive reactions are non specific. However, serology is useful to identify previous infection in epidemiologic study. The ELISA has been recentiy validated for the diagnosis of bovine schistosomiasis and will probably replace the other serological tests. The immunoblotting technique has been proven satisfactory to detect antibodies to defined and recombinant schistosome antigen vaccines. Nucleic acid hybridization techniques have been described for the study of schistosome species-specific identification. However, these molecular techniques have not yet revolutionarized diagnosis of schistosomiasis. These techniques will probably serve as the basis for future diagnostic tests.
