Overview

Case report demonstrates asymmetric obstructive and suppurative renal lesions in a calf with Proteus mirabilis infection, highlighting the need for bilateral diagnostic imaging.

Key Points

To describe the clinical presentation, diagnostic imaging, and postmortem findings of asymmetric urinary tract lesions caused by Proteus mirabilis in a beef calf.
Evaluated an 8-month-old Japanese Black heifer calf presenting with anorexia, dysuria, and abdominal pain via clinical examination and abdominal ultrasonography.
Provided supportive therapy and ceftiofur antimicrobial treatment prior to performing gross autopsy and bacterial cultures of urine, urinary tissues, and an urachal remnant.
Ultrasonography and postmortem examination identified marked left renal hydronephrosis with struvite calculi alongside severe right renal pyonephrosis without calculi.
Bacteriological culture confirmed Proteus mirabilis in urine antemortem and within suppurative exudate from both kidneys, ureters, urinary bladder, and an urachal remnant abscess postmortem.
