Renal abscessation in dromedary camels: Clinical, ultrasonographic, hematobiochemical, and etiological investigations.

Background: Although renal abscessation is rarely reported in dromedary camels, it is increasingly detected in this species. Aim: This study aimed to investigate renal abscessation in camels with special emphasis on ultrasonographic findings and causative agents. Methods: Seventeen diseased camels ( Results: The signs of diseased camels included general gradual and/or progressive weakness, inappetence or anorexia, passage of dry feces, dysuria, bloody feces, lameness, bloody urine, and abdominal pain. Neutrophilic leukocytosis is the most significant hematological abnormality. Significant biochemical alterations included hyperproteinemia, azotemia, hyperglycemia, and increased serum alkaline phosphatase activity. Single or multiple renal abscesses were visualized sonographically compressing the renal parenchyma. Three abscesses measuring 5.2-15.0 cm were scanned in 2 camels; one affected the left and the other affected the right kidneys. In addition, two abscesses were imaged in 2 camels; both are affecting the left kidney. However, single abscesses measuring 3.6-14.0 cm in length were recorded in the remaining 13 camels; nine in the right and four in the left kidneys. The contents of the abscesses were hyperechogenic in 8 cases, hypoechoic in 4, isoechoic with hyperechoic foci in 3 cases, and heterogenous in 2. In 4 of the 17 diseased camels, hyperechoic urine and echogenic deposits were found within the urinary bladder. Bacteriological examination showed pure growth of Conclusion: Sonography is extremely helpful for verifying renal abscesses and is a good guide for abscess aspiration in dromedary camels.
