Changes in the SUSPPUP ratio and fractional excretion of strong monovalent electrolytes in hospitalized dogs with canine babesiosis.

In this study an increased SUSPPUP ratio and fractional excretion of potassium in dogs infected with Babesia canis suggested mineralocorticoid excess in canine babesiosis. A significant increase in strong monovalent electrolyte fractional excretions in azotaemic dogs infected with B. canis probably resulted from acute tubular necrosis.
