Interpretive Summary: Neospora caninum is a recently discovered protozoan (single-celled) parasite of animals. It causes abortion in livestock and paralysis in companion animals. Its life cycle and sources of infections are unknown. Transplacental transmission is the only recognized mode of transmission. Scientists at Beltsville Agricultural Research Center and the Cairo University, Egypt report for the time N. caninum infection in water buffaloes and in Egypt. The results will be of interest to veterinarians, parasitologists and pathologists.

Technical Abstract: Dubey J.P., Romand S., Hilali M., Kwok O.C.H. & Thulliez P. 1997. Seroprevalence of Antibodies to Neospora caninum and Toxoplasma gondii in Water Buffaloes (Bubalus bubalis) from Egypt. International Journal for Parasitology. Sera from 75 water buffaloes from Egypt were examined using direct agglutination test incorporating mercaptoethanol for antibodies to Neospora caninum and Toxoplasma gondii. Antibodies to N. caninum were found in 51 (68%) of 75 buffaloes in titers of 1:20 (6 buffaloes), 1:40 (15 buffaloes), 1:160 (1 buffalo),1:320 (1 buffalo), and ò1:640 (28 buffaloes), using N. caninum formalin preserved whole tachyzoites as antigen. Antibodies to T. gondii were not found in a 1:100 dilution of serum of any of the 75 buffaloes, using T. gondii as antigen, indicating specificity in the detection of antibodies to N. caninum. This is the first report of N. caninum prevalence in water buffaloes.
