Suppurative Nephritis, Pyelonephritis, Mouse
Bacterial lesions are usually focal in their distribution but, depending on their severity, may be multifocal or even confluent. Individual lesions may be tan or white and are slightly elevated when abscesses are formed. On cut surface there may be purulent exudate in the pelvis and red to white linear streaks often extend from the renal papillae into the cortex. Abscesses may be present anywhere in the renal parenchyma. Embolic lesions are usually limited to the cortex but may be present in the medulla as well (Jones et al. 1972; Maronpot and Peterson 1981).
