Bilateral renal abscessation and chronic active pyelonephritis in a male camel (Camelus dromedarius) caused by Escherichia coli.

This report summarizes the clinical, hematobiochemical, ultrasonographic, histopathological and bacteriological findings in a male Arabian camel (Camelus dromedarius) with bilateral renal abscessation and chronic active pyelonephritis. Owner complaint included a decreased appetite and loss of body condition with occasionally voiding red urine. In the right kidney, ultrasonographic changes included a hypoechoic fluid surrounding the renal parenchyma. Within the left kidney, a large volume of hypoechoic contents were imaged. Bacteriological examination yielded only Escherichia coli. To the authors' knowledge this is the first reported case of bilateral renal abscessation and chronic active pyelonephritis in dromedary camels. In conclusion, renal ultrasonography provides a precise and non-invasive technique for diagnosis and subsequent clinical decision making of renal abscessation and chronic pyelonephritis camels.
