First molecular detection of Neospora caninum in European brown bear (Ursus arctos)

Abstract

Neospora caninum is an important intracellular protozoan parasite with an affinity to the central nervous system of many animals and a major causative agent of repeated abortions in cattle. In total, 45 muscle, liver, or spleen samples of brown bear sampled in different locations of Central Slovakia were examined by PCR. Genotyping of N. caninum was based on amplification of Nc-5 gene and ITS1 rRNA fragments and subsequent sequencing. Presence of N. caninum DNA was confirmed in 24.4% (11/45) of tested animals. The results obtained in study confirm the first molecular evidence of N. caninum DNA in European brown bear (Ursus arctos) in Slovakia.
