The influence of starvation and Eurytrema coelomaticum infection on the nitrogenous products of degradation in the hemolymph of Bradybaena similaris

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 rati...
