Plain-English summary
A 6-year-old Cheval Canadien mare was brought to the vet because she was showing signs of sudden kidney problems after receiving pain relief medication. Tests on her urine showed tiny organisms called Klossiella equi, which had not been seen in this way before. The mare was treated with fluids given through an IV, and as her kidney function improved, the protozoa in her urine disappeared. After about a week in the hospital, she was sent home, and follow-up tests over the next year showed her kidney health returned to normal, with no signs of the protozoa in her urine.
Abstract
A 6-year-old Cheval Canadien mare was presented for clinical signs related to acute kidney injury after receiving a course of nonsteroidal anti-inflammatory therapy. Cytologic examination of concentrated urine revealed small protozoal organisms that were later identified as Klossiella equi. Both sporocysts and free-floating sporozoites were identified in the urine, which has not been previously documented. The mare responded well to intravenous fluid therapy, and as she regained tubular function, the presence of the protozoa in the urine also abated. The mare was discharged from the hospital after approximately 1 week of therapy. Repeat serum chemistries for up to 1 year following discharge demonstrated that all renal parameters had returned to normal, and the protozoa were not visualized on cytologic examination of the collected urine samples.
