The urea and uric acid contents in the hemolymph of Bradybaena similaris were analyzed under starvation and Eurytrema coelomaticum infection during 30 days. The urea and uric acid contents in the uninfected and fed snails were 15.090 mg/dl and 9.399 mg/dl, respectively, being the urea/uric acid ratio 1.6. The urea content in starved snails increased to a maximum of 363.237 mg/dl at 15 days, and the uric acid varied to a maximum of 11.470 mg/dl. The urea content in infected snails was reduced to a minimum of 2.123 mg/dl at 30 days of infection and the uric acid increased significatively at 25 days post exposure, being 13.820 mg/dl. A significative relation was not observed between the time of starvation and time of E. coelomaticum infection and the uric acid content in the hemolymph of B. similaris.
