Two groups of rabbits, with 10 animals each, were artificially infected with varying doses of sporulated intestinal coccidia oocysts. The first group was infected with 2x10(5), whereas the second received 4x10(5) infectious oocysts. The infectious material consisted of several rabbit intestinal coccidia oocyst species: Eimeria flavescens, Eimeria matsubayashi, Eimeria magna, Eimeria neoleporis, Eimeria perforans and Eimeria media. A third group of 10 rabbits served as the control. Following the artificial infection, in most animals a subclinical form of the disease was induced with weight loss, bristling hair and polydipsia while only 3 animals developed full-blown with diarrhoea. Immediately before and then on days 4, 7, and 10 after the infection, levels of the following electrolytes were determined in blood: sodium, potassium, chloride and calcium. Additionally, the concentration of sodium, potassium and chloride was measured in urine samples. A decrease in plasma sodium, potassium ...and chloride concentrations was observed with a concomitant rise in the levels of these electrolytes in urine. Plasma calcium concentrations varied, both rising and dropping in the course of the disease. The changes in concentration of the measured electrolytes in blood and urine did not correlate with the size of the inoculum of sporulated coccidia oocysts.
