Objective. To evaluate the frequency of anti-N. Caninum antibodies in two sheep herds in the department of Córdoba, Colombia. Materials and methods. The study was performed in the department of Córdoba (Colombia) in two sheep farms that had a clinical history of abortions and death of adult animals; 28 female adults of creole hair (camura) breed were sampled at random. A recombinant peptide from the parasite (NcGRA1) was used in DOT-ELISA tests and the serum was diluted 1:200. Results. This study reports for the first time in this department, and the country the anti-N. Caninum in 78.6% (22/28) of the sheep sampled. Conclusions. These results confirm the Neospora caninum infection in sheep and the need for new studies linking the presence of the parasite with clinical manifestations in different regions of the country.

Objective. Evaluate and characterize the clinical and histopathological aspects of cutaneous Pythiosis in calves the department of Córdoba, Colombia. Materials and methods. A descriptive, non-probabilistic, convenience study was conducted in animals. 14 calves were with skin Pythiosis were analyzed, which underwent clinical and histopathologic characterization using hematoxylin-eosin and Grocott staining. Results. Clinically, the animals developed humid skin ulcers with abundant fibrin bloody exudation, some had irregular surface nodules and bleeding and in some cases, yellowish white caseous material. Lesions were located in most cases, on the distal parts of the limbs and the ventro-lateral region of the neck. Histopathologically, in hematoxylin-eosin staining, pyogranulomas and a multiple central area constituted by agglomerates of eosinophiis and neutrophils, some of them surrounded by macrophages and giant cells (Splendore-Hoeppli reaction) were observed. The Grocott stain showed multiple septate and partially branched, ¡ntralesional, straight, brown hyphae. Conclusions. The definitive diagnosis of the disease was based on epidemiology, macroscopic characteristics of lesions and histopathologic findings, as being conclusive diagnostic methods for bovine cutaneous Pythiosis.
