The purpose of the present study was to evaluate serum canine Cystatin-C (Cys-C) concentration for the prediction of renal function (RF) in dogs naturally infected with Babesia canis vogeli and Ehrlichia canis. A total of 46 dogs were enrolled into three groups. Group B included 16 dogs naturally infected with B. c. vogeli, group E 10 dogs naturally infected with E. canis [dogs diagnosed as canine monocytic ehrlichiosis (CME)], and group H involved 20 healthy controls (negative for B. c. vogeli and E. canis). Solely dogs presenting uncomplicated babesiosis caused by B. c. vogeli were enrolled. Serum urea and serum creatinine (Cre) levels with serum Urea:Cre ratios were analyzed. Canine serum Cys-C was determined with a species-specific commercially available and validated ELISA assay as a reference. Mean serum Cys-C levels were 5.28 mg/L, 3.02 mg/L, and 2.30 mg/L for groups B, E and H, respectively. RF in uncomplicated CB caused by B. c. vogeli seems to be affected based on serum Cys-C concentrations. To the author's knowledge, this is the first study reporting that mean serum canine Cys-C levels in dogs with CME demonstrated no elevation. Serum canine Cys-C as a novel RF marker could be used for early detection of renal injury in both babesiosis and CME.

Introduction: This study consisted in histopathological and immunohistochemical examinations of the central nervous system of 15 sheep suspected of infection with Coenurus cerebralis. The sheep displayed compulsive circling and were submitted for necropsy in 2012–2016.

Material and Methods: Species identification was made on the basis of the PCR analysis and parasitological examination of the cysts.

Results: Coenurus cerebralis cysts were detected only in the cerebral tissue of 13 sheep and in the cerebral and cerebellar tissues of 2 animals. Out of the 33 parasite cysts, most (21.21%) were located in the right and left frontal lobes of the cerebrum. The largest cyst measured 6 × 5 cm and the smallest cyst was 2 × 2 cm in size. The highest and lowest numbers of scolices were 55 and 21, and the number of rostellar hooks ranged between 22 and 30. Histopathological examination revealed the presence of typical parasitic granulomatous inflammatory foci. Immunohistochemical staining showed that most common in the periphery of the parasite cysts were, in descending order by cell number, GFAP, CD163, CD3, and CD79α-positive cells.

Conclusion: The study confirms the role of cellular defence mechanisms in the pathogenesis of Coenurus cerebralis infection in sheep.
